It’s been a marvelous few months following Venus rise and fall across the evening sky, in its best show in eight years.
Venus is now gone from our western sky, but since late 2019 until late May 2020 it had dominated the sky as a brilliant evening star.
Here’s a gallery of Venus portraits I shot during its wonderful show these last few months.
The show began in November 2019 when rising Venus met declining Jupiter on November 23 for a fine conjunction of the two brightest planets in the evening twilight.
A week later I captured the line of the then three evening planets and the Moon across the southwest, defining the path of the ecliptic across the evening sky.
A week after that I took the opportunity to shoot some selfies of me with binoculars looking at Venus, as it met Saturn in a wide conjunction, with Venus then still low in the southwest. It was just beginning its climb up into the western sky.
A month later in mid-winter, Venus was still rather low but brilliant even in a hazy moonlit sky, as I posed for another selfie, this time with a small telescope. These images are always useful for illustrations in books and magazines. And blogs!
By the end of February Venus had climbed high into the west, and was appearing monthly near the waxing crescent Moon. This is another binocular selfie from February 27.
In March I visited Churchill, Manitoba just as the lockdown and travel restrictions were coming into effect. But our lone and last tour group at the Churchill Northern Studies Centre saw some fine auroras, as here on this evening with the Northern Lights appearing even in the twilight. And what’s that bright star? Venus, of course!
Upon my return home to Alberta, I was able to shoot more panoramas on the prairies of the wonderful early spring sky with Orion setting into the twilight and Venus in Taurus shining below the iconic Pleiades star cluster.
March 26 was a superb night for catching Venus now at its highest and almost at its brightest at this appearance, as the waxing Moon appeared below it.
The highlight of the spring Venus season was its close approach to the Pleiades, which it passes only every 8 years. Here I am viewing the conjunction two days before the closest approach, with Orion over my shoulder.
The night of closest approach, April 3, was cloudy, but here is a consolation closeup taken the next night with brilliant Venus departing the Seven Sisters.
Later in April Venus reached its greatest brilliancy, at magnitude -4.7, the date when the size of is disk, phase, and proximity to Earth converge to make Venus as bright as possible. On this night I shot the Moon, then 30° away from Venus and the planet with the same gear to show their relative sizes and similar crescent phase this night. The caption provides more details.
A week later, with Venus just past its point of greatest brilliancy, I shot the planet by daylight in the early evening sky, using a telescope to zoom into the planet to show its waning crescent phase. By this time the phase was obvious in binoculars.
But Venus was now dropping rapidly from sight. By May 23, it was low in the twilight and below Mercury, then at its best for 2020 for an evening appearance from my latitude. Note the thin Moon below the planets. This was a superb sight for binoculars.
By May 29, Venus was now tough to pick out of the evening sky, and a challenge to shoot even by day, as it then stood only 8° away from the Sun. What was once obvious to the naked eye now took a computerized telescope to pick out of the noon-day blue sky. A telescope showed the now razor-thin crescent as Venus approached its June 3 “inferior conjunction” — its passage between Earth and the Sun.
I shot and narrated video footage of the thin crescent Venus, my parting shots of Venus for its evening appearance in 2020.
But in June, post inferior conjunction, it will rise very quickly into our morning sky, providing a mirror-image repeat performance as a morning star for the rest of 2020.

I wish you all the best and a safe and healthy time in 2020. Take some solace in what the sky can show us and in the beauty of the night.
I spent a wonderful week touring the star-filled nightscapes of southwest Saskatchewan.
On their license plates Saskatchewan is billed as the Land of Living Skies. I like the moniker that Saskatchewan singer-songwriter Connie Kaldor gives it – the sky with nothing to get in the way.
Grasslands National Park should be a mecca for all stargazers. It is a Dark Sky Preserve. You can be at sites in the Park and not see a light anywhere, even in the far distance on the horizon, and barely any sky glows from manmade sources.
The lead image shows the potential for camping in the Park under an amazing sky, an attraction that is drawing more and more tourists to sites like Grasslands.
This is a multi- panel panorama of the Milky Way over the historic 76 Ranch Corral in the Frenchman River Valley, once part of the largest cattle ranch in Canada. Mars shines brightly to the east of the galactic core.
Mars and the Milky Way over the tipis at Two Trees area in Grasslands National Park, Saskatchewan on August 6, 2018. Some light cloud added the haze and glows to the planets and stars. Illumination is by starlight. No light painting was employed here. This is a stack of 8 exposures for the ground, mean combined to smooth noise, and a single untracked exposure for the sky, all 30 seconds at f/2.8 with the Sigma 20mm lens, and Nikon D750 at ISO 6400 with LENR on.
Mars (at left) and the Milky Way (at right) over a single tipi (with another under construction at back) at the Two Trees site at Grasslands National Park, Saskatchewan, August 6, 2018. I placed a low-level warm LED light inside the tipi for the illumination. This is a stack of 6 exposures, mean combined to smooth noise, for the ground, and one untracked exposure for the sky, all 30 seconds at f/2.2 with the 20mm Sigma lens and Nikon D750 at ISO 3200.
The Big Dipper and Arcturus (at left) over a single tipi at the Two Trees site at Grasslands National Park, Saskatchewan, August 6, 2018. This is a stack of 10 exposures, mean combined to smooth noise, for the ground, and one untracked exposure for the sky, all 30 seconds at f/2.8 with the 20mm Sigma lens and Nikon D750 at ISO 6400. Light cloud passing through added the natural star glows, enlarging the stars and making the pattern stand out. No soft focus filter was employed, and illumination is from starlight. No light painting was employed. Some airglow and aurora colour the sky. A Glow filter from ON1 Photo Raw applied to the sky to further soften the sky.
At the Two Trees site visitors can stay in the tipis and enjoy the night sky. No one was there the night I was shooting. The night was warm, windless, and bug-less. It was a perfect summer evening.
From Grasslands I headed west to the Cypress Hills along scenic backroads. The main Meadows Campground in Cypress Hills Interprovincial Park, another Dark Sky Preserve, is home every year to the Saskatchewan Summer Star Party. About 350 stargazers and lovers of the night gather to revel in starlight.
The Perseid meteor shower over the Saskatchewan Summer Star Party, on August 10, 2018, with an aurora as a bonus. The view is looking north with Polaris at top centre, and the Big Dipper at lower left. The radiant point in Perseus is at upper right. The sky also has bands of green airglow, which was more prominent in images taken earlier before the short-lived aurora kicked up. The aurora was not obvious to the naked eye. However, the northern sky was bright all night with the airglow and faint aurora. This is a composite of 10 images, one for the base sky with the aurora and two faint Perseids, and 9 other images, each with Perseids taken over a 3.3 hour period, being the best 9 frames with meteors out of 360. Each exposure was 30 seconds at f/2 with the 15mm Laoawa lens and Sony a7III at ISO 4000. I rotated all the additional meteor image frames around Polaris to align the frames to the base sky image, so that the added meteors appear in the sky in the correct place with respect to the background stars, retaining the proper perspective of the radiant point.
A Perseid meteor streaks down the Milky Way over the Saskatchewan Summer Star Party in the Cypress Hills of southwest Saskatchewan, at Cypress Hills Interprovincial Park, a Dark Sky Preserve. The Milky Way shines to the south. About 350 stargazers attend the SSSP every year. Observers enjoy their views of the sky at left while an astrophotographer attends to his camera control computer at right. This is a single exposure, 25 seconds, with the Laowa 15mm lens at f/2 and Sony a7III camera at ISO 3200.
This year coincided with the annual Perseid meteor shower and we saw lots!
Most nights were clear, and warmer than usual, allowing shirt-sleeve observing. It was a little bit of Arizona in Canada. Everyone enjoyed the experience. I know I did!
SSSP and Cypress Hills are stargazing heaven in Canada.
From Cypress Hills I drove due north to finally, after years of thinking about it, visit the Great Sandhills near Leader, Saskatchewan. Above is a panorama from the “Boot Hill” ridge at the main viewing area.
The Sandhills is not a provincial park but is a protected eco zone, though used by local ranchers for grazing. However, much of the land remains uniquely prairie but with exposed sand dunes among the rolling hills.
There are farm lights in the distance but the sky above is dark and, in the panorama above, colored by twilight and bands of red and green airglow visible to the camera. It’s dark!
In the twilight, from the top of one of the accessible sand dunes, I shot a panorama of the array of four planets currently across the sky, from Venus in the southwest to Mars in the southeast.
This is the kind of celestial scene you can see only where the sky has nothing to get in the way.
If you are looking for a stellar experience under their “living skies,” I recommend Saskatchewan.
Mars and Jupiter are meeting up in the morning sky. Soon they’ll be joined by the Moon.
Here’s a heads up for one of the best planet conjunctions of the year. Mars and Jupiter are now close together in the dawn sky to the south, and getting closer!
Above is the actual view on the morning of January 4, with Jupiter the brightest of a trio of objects. Mars is reddish and in the middle. The object at right is the star Alpha Librae, also known as Zubenelgenubi in Libra.
As shown in the simulation above, on the morning of January 6 Mars and Jupiter will be only 1/3rd of a degree apart (20 arc minutes), so close that dimmer Mars might not be obvious to the naked eye next to bright Jupiter. But use binoculars to show the planet pair.
The next morning, on January 7, they will appear almost as close, as Jupiter climbs higher past Mars.
As shown here, on the morning of January 11 the waning crescent Moon will sit only 4 degrees from the planet pair, with all three worlds gathered close enough for binoculars to frame the scene.
With sunrise coming late on winter mornings, it doesn’t take an early rise to take in the dawn scene. Make a note to take a look about 6:30 to 7:00 a.m. over the next week.
POSTSCRIPT added January 6:
Here’s the real scene from the morning of January 6, with Mars and Jupiter just 16 arc minutes apart, very close but still easy to distinguish with the naked eye. Jupiter did not overwhelm Mars.
Saturn, Mars and the Milky Way appeared in the twilight over the Bow River.
I shot this scene on August 24 from the viewpoint at Blackfoot Crossing Historical Park, overlooking the Bow River. Mars appears between Saturn above and Antares below, in a line of objects west of the Milky Way.
The valley below is the traditional meeting place of the Blackfoot Nation, and the site of the signing of Treaty Seven between Chief Crowfoot and Colonel MacLeod of the North West Mounted Police in 1877.
The image is a panorama of two images, each 20-second exposures at f/2 and ISO 1600 with the 24mm lens. I shot them just prior to shooting time-lapses of the moving sky, using two cameras to create a comparison pair of videos, to illustrate the choices in setting the cadence when shooting time-lapses.
The movies, embedded here, will be in the next edition of my Nightscapes and Time-Lapse ebook, with the current version linked to below. The text explains what the videos are showing.
Choose Your Style
When shooting frames destined for a time-lapse movie we have a choice:
Shoot fewer but longer exposures at slower ISOs and/or smaller apertures.
Shoot lots of short exposures at high ISOs and/or wide apertures.
The former yields greater depth of field; the latter produces more noise. But with time-lapses, the variations also affect the mood of a movie in playback.
This comparison shows a pair of movies, both rendered at 30 frames per second:
Clip #1 was taken over 2 hours using 20-second exposures, all at ISO 2000 and f/2 with 1-second intervals. The result was 300 frames.
Clip #2 was taken over 1 hour using 5-second exposures also at f/2 and 1-second intervals, but at ISO 8000. The result was 600 frames: twice as many frames in half the time.
Clip #2 exhibits enough noise that I couldn’t bring out the dark foreground as well as in Clip #1. Clip 2 exhibits a slower, more graceful motion. And it better “time-resolves” fast-moving content such as cars and aircraft.
Which is better? It depends …
Long = Fast
The movie taken at a longer, slower cadence (using longer exposures) and requiring 2 hours to capture 300 frames resulted in fast, dramatic sky motion when played back. Two hours of sky motion are being compressed into 10 seconds of playback at 30 frames per second. You might like that if you want a dramatic, high-energy feel.
Short = Slow
By comparison, the movie that packed 600 frames into just an hour of shooting (by using short exposures taken at fast apertures or fast ISOs) produced a movie where the sky moves very slowly during its 10 seconds of playback, also at 30 frames per second. You might like that if you want a slow, peaceful mood to your movies.
So, if you want your movie to have a slow, quiet feel, shoot lots of short exposures. But, if you want your movie to have a fast, high-energy feel, shoot long exposures.
As an aside – all purchasers of the current edition of my ebook will get the updated version free of charge via the iBooks Store once it is published later this year.
Mars outshines his rival red star Antares in the heart of the Scorpion.
This was the view last night from my observing site in Australia, of red Mars shining near the red star Antares, whose very name means “rival of Mars.” But as Mars nears its closest approach to Earth next month it is already far brighter than Antares, easily winning the rivalry now.
The view takes in the head of Scorpius, one of the most colourful areas of the night sky when photographed in long exposures. Uniquely, Antares illuminates a nearby dust cloud with its light which is more yellow than red.
Other dust clouds reflect the blue light of hot young stars in this section of the Milky Way. Red nebulas are emitting their own light from glowing hydrogen.
The area around Antares is also streaked with lanes of dark dust that absorb light and at best appear a dull brown.
Mars reaches its closest point to Earth since 2005 on May 30. All through May and June Mars will shine as a brilliant red star near Antares. A telescope will provide the best view of the red planet we’ve had in a decade.
While you are in the area aim your telescope a little to the east to catch Saturn, also in the area, though technically over the border in the constellation of Ophiuchus the Serpent Bearer.
In the view above, Saturn is the bright “star” to the left of Mars. Saturn reaches its closest to Earth in early June. Its rings are now wide open and a spectacular picture postcard sight in any telescope.
This final view shows Mars and Saturn rising with Scorpius in the moonlight from two nights ago. From my current latitude of 32° south, Scorpius comes up on his side.
The morning planets are now strung out along the ecliptic, visualizing this line in the sky.
This was the view this morning, November 14, of the three dawn planets lined up along the ecliptic, with the stars Spica and Regulus also defining this imaginary line.
The ecliptic is the Earth’s orbital path around the Sun projected into the sky. So it is along this line that we see the Sun appear to move around the sky over a year. But it is also the path along which we find the seven other major planets – in this case, three of them: Venus, Mars and Jupiter.
These three worlds were clustered together in October, but are now spreading out along the ecliptic, as Venus drops lower but Mars and Jupiter climb higher.
The stars Spica and Regulus also lie along the ecliptic, where the Moon can occasionally pass in front of, or occult, these stars.
So the two stars and three planets are now nicely drawing the ecliptic line for us in the dawn sky. At this time of year, the ecliptic is also steeply angled above the eastern horizon.
The main image above is a stack of 4 x 20 second exposures for the ground, to smooth noise, and one 20-second exposure for the sky, all with the Nikon D810a at ISO 1000 and Nikkor 14-24mm lens at f/2.8 and at 14mm.
This image just above is with the same gear but with the lens at the 24mm setting to more tightly frame the planets.
Meanwhile, on the other side of the sky at dawn, Orion and his winter sky friends were setting into the west (image below).
All the images here are shot with the Nikon D810a camera and the amazing Nikkor 14-24mm lens, two items in hand this month for testing and review. A thorough test will appear in future blogs.
Of course, as wonderful as the gear is, it cannot extract the ecliptic line and labels from the sky – those are added in Photoshop!
This was the trio of planets at their best in the morning sky.
On the morning of October 28, Mars, Venus and Jupiter formed a neat isosceles triangle in the twilight. Venus, the brightest, was in the middle, with Mars below and Jupiter above. The grouping shone amid the stars of Leo, with its brightest star, Regulus, above the windmill in the lead image above. The rest of Leo lies above the planets.
To capture the scene I drove west at 5 am to a farmstead I had shot at before, in June, to capture Venus and Jupiter, also then in Leo near Regulus, but in the evening sky looking west. Click here for that blog post from mid-June.
This morning, the Moon, just past full as the annual Hunter’s Moon, shone in the west off camera lighting the landscape.
The dawn sky colours and the moonlit red barn made for a fine colour contrast.
After today, the planet configuration breaks up, as Venus descends to meet Mars on November 2 and 3, while Jupiter climbs higher. But another great morning sight awaits on November 7 when the waning crescent Moon will shine near the Venus-Mars pairing, with Jupiter above.
On the way home I stopped at fog-bound Lake MacGregor to capture the planets in a brightening dawn sky over the misty waters.
This morning the three planets lay just 4.5 degrees apart, close enough to frame in high-power binoculars.
We won’t see these three planets this close to each other in a darkened sky — as opposed to being so close to the Sun we really can’t see them — until November 21, 2111.
Four planets appear in the dawn sky outlining the morning ecliptic.
This morning, October 20, I was able to capture four planets in the morning sky, arrayed along the ecliptic.
From bottom to top they are: Mercury (just past its point of greatest elongation from the Sun), dim Mars, bright Jupiter, and very bright Venus (just 6 days away from its point of greatest elongation from the Sun). Above Venus is Regulus, in Leo.
I’ve added in the labels and the line of the ecliptic, rising steeply out of the east in the autumn dawn sky.
Of course, there is a fifth unlabelled planet in the scene, quite close in the foreground.
The image below is an unlabeled version.
Mercury will be disappearing from view very quickly now as it drops back down toward the Sun.
But over the next week the three higher planets will converge into a tight triangle just 4.5 degrees apart. We won’t see these three planets this close together in a darkened sky until November 2111.
I shot the scene from home in southern Alberta. The image is a composite stack, with manually created masks (not an HDR stack), of 5 exposures, from 15 seconds to 1 second, to contain the range of brightness from the bright horizon to the dimmer star-filled sky higher up. All are with the 35mm lens and Canon 6D at ISO 800.
You might have already seen Venus shining brightly in the morning sky. And perhaps you’ve seen a slightly less bright object below it. That’s Jupiter.
But there’s a third, even dimmer planet accompanying Venus and Jupiter — reddish Mars. On the morning of Saturday, October 17 (chart above ⬆️) Mars and Jupiter pass just 1/2 degree apart, for a mismatched double “star” at dawn.
The planets put on an even better show in the following 10 days as all three converge to form a tight triangle of worlds in the morning sky.
On October 23 ⬆️, Venus, Mars and Jupiter appear in a close grouping just 4.5 degrees apart, close enough to each other to be easily contained in the field of typical binoculars, the circle shown in these charts.
Two mornings later, on October 25 ⬆️, Venus and Jupiter are at their closest apparent separation, just 1 degree apart, for a brilliant double “star” in the morning twilight. If you miss this morning, on the next morning, October 24, the two planets appear about the same distance apart as well.
By October 28 ⬆️, the three planets have switched positions, as Venus drops lower but Jupiter climbs higher. But they again appear in a triangle, 4.5 degrees wide.
The motion you’re seeing from day to day is due to a combination of the planets’ own orbital motions around the Sun, as well as our planet’s motion.
Keep in mind, the planets aren’t really close together in space. They lie tens, if not hundreds, of millions of kilometres apart. They appear close to each other in our sky because they lie along the same line of sight.
Do try to get up early enough — between 6 a.m. and 6:30 a.m. should do it — to look east to see the changing configuration of planets as they dance at dawn. Binoculars will provide the best view.
This is a rare sight! We won’t see these three planets this close to each other in a darkened sky until November 20, 2111!
Look east this week to see a wonderful conjunction of the waning Moon with three planets in the morning sky.
A great dance of the planets is about to begin in the dawn sky.
Venus, Mars and Jupiter are now all prominent in the eastern sky before sunrise, with Venus by far the brightest. Below it shines slightly dimmer Jupiter. But between those two brightest of planets shines dim red Mars.
The three planets are converging for a mutual close meeting in the third week of October, when from October 23 to 28 the trio of planets will appear within a binocular field of each other.
But this week, with the three planets still spread out along a line, the Moon joins the scene to start the planet dance. It shines near Venus on the morning of October 8 (as shown here). and then near Mars and Jupiter on October 9.
Look east between 5:30 and 6:30 a.m. local time. All the planets are easy to see with unaided eye even in the city, but binoculars will frame the Moon-Venus pairing on October 8 and the Moon-Mars-Jupiter trio on October 9.
On the morning of September 10 the waning crescent Moon gathered near bright Venus and much dimmer but redder Mars (at left) in the dawn sky.
Venus and Mars have both moved into the morning sky, where they will begin a series of conjunctions with the Moon and with Jupiter, now just emerging from behind the Sun, over the next two months. This gathering is just the start of the dawn planet dance.
For the technically minded, this is a high-dynamic range stack of 5 exposures to accommodate the large range in brightness between the sky and Moon, and to preserve the earthshine on the “dark side of the Moon.”
I shot this with the Canon 6D and 135mm lens at f/2 and at ISO 800 in a set of 8, 4, 2, 1 and 0.5-second exposures, blended with HDR Pro in Photoshop using 32-bit mode of Adobe Camera Raw.
During the week of July 13 to 17 we are witness to a momentous event in space exploration. Here’s how to follow along!
During the last week, and next, I’m out of photography for awhile and back into planetarium programming and production mode, my old day-job for decades. What has brought me back to the programming console is the once-in-history exploration of a new world – Pluto by the New Horizons probe.
I’m presenting a live public talk at the TELUS Spark science centre in Calgary on July 16 to present the new images. In the talk I use the amazing Evans and Sutherland Digistar digital planetarium system to fly people along with New Horizons as it makes its historic encounter.
Here, I present images of some of the full-dome immersive scenes I’ve programmed for the lecture. The top image is from the animation that places the audience alongside New Horizons as it flies from Earth and then through the Pluto system.
This image is the template scene into which I’ll drop what we hope will be even better images next week.
Here we fly out of the solar system to see the orbit of Pluto and its dwarf planet companions, as well as other objects of the Kuiper Belt, in perspective.
In this scene we land on Pluto to see the sky as it will appear next week during the encounter, complete with moons in the Plutonian sky.
To put the mission into historic perspective I also take people inside the observatory where Clyde Tombaugh discovered Pluto in 1930.
And we’ll also visit dwarf planet Ceres, and fly to the Rosetta comet (above) to watch Philae land, and bounce!
For those in the Calgary area able to attend, you can find more details about my July 16 talk at the TELUS Spark website. The talk is in the Digital Dome at 4 pm and is free.
But to follow along with the mission from anywhere on Earth I recommend bookmarking these sites:
The summer solstice sky was filled with twilight glows, planets, and dancing Northern Lights.
What a magical night this was. The evening started with the beautiful sight of the waxing crescent Moon lined up to the left of the star Regulus, and the planets Jupiter and Venus (the brightest of the trio), all set in the late evening twilight.
They are all reflected in the calm waters of a prairie lake.
I shot the above photo about 11 p.m., as late a twilight as we’ll get. From here on, after solstice, the Sun sets sooner and the sky darkens earlier.
Later, about 12:30 a.m., as predicted by aurora apps and alert services, a display of Northern Lights appeared on cue to the north. It was never very bright to the eye, but the camera nicely picks up the wonderful colours of a solstice aurora.
At this time of year the tall curtains reaching up into space catch the sunlight, with blue tints adding to the usual reds fringing the curtain tops, creating subtle shades of magenta and purple.
The display made for a photogenic subject reflected in the lake waters.
Each night, Venus and Jupiter are converging closer, heading toward conjunction on June 30.
This was Venus (right) and Jupiter (centre) with Regulus at left, in a cloudy twilight sky on Friday, June 12, as Venus and Jupiter converge toward their close conjunction in the evening sky on June 30.
Be sure to watch each night as the two brightest planets in the sky creep closer and closer together. Mark June 19 and 20 on your calendar, as that’s when the waxing crescent Moon will join the duo.
I shot this from near Vulcan, Alberta, after delivering an evening program at the Trek Centre in Vulcan as a guest speaker. Clouds prevented us from seeing anything in the sky at the public event, but on my way home skies cleared enough to reveal the two bright planets in the twilight.
I stopped at an abandoned farmyard I had scouted out earlier in the evening, to serve as a photogenic backdrop.
This is a high dynamic range stack of three bracketed exposures, one stop apart, to record detail in both the dark foreground as well as in the bright sky.
It was a fine celestial sight to begin the week, as Venus met Jupiter in the dawn sky.
This morning, August 18, Venus and Jupiter appeared just 1/2 degree apart, as close as they’ve appeared to each other since 1999.
The top image shows the wide-angle setting, with Venus and Jupiter tightly paired near the horizon, and the waning Moon above, itself in conjunction with Aldebaran in the Hyades star cluster.
This zooms into the main event, the Venus-Jupiter pairing, as they were emerging from the horizon haze.
I shot this from home, off the back deck, having little ambition at 5 a.m. to venture any further afield. I had planned to shoot this from Dinosaur Park but had second thoughts on the hour drive there and back!
This zooms into the secondary show this morning, the meeting of the waning crescent Moon with the brightest star in Taurus, Aldebaran, and its companion stars in the Hyades star cluster. This is a telephoto lens shot with a fixed camera, no tracking.
Thus begins a fine two weeks of stargazing, weather permitting, as the Moon exits the sky to leave us the summer Milky Way at its best, and dual pairs of planets in the dusk and dawn sky – Mars and Saturn converging in the evening and Venus and Jupiter, now parting ways, in the morning.
The evening planet show we’ve been enjoying all year comes to a close for a while, but in grand style with a convergence of four worlds in the dusk.
This was the scene from my front driveway, Tuesday, August 21, as the waxing crescent Moon shone near Mars (just above the Moon) and Saturn (at top right just above the clouds), and near the star Spica (to the right of the Moon). The four objects formed a somewhat lopsided square in the evening twilight. But from my latitude of 51° North, they were very low and never visible in a dark sky. Enjoying them with the eyes required binoculars to pick them out.
Saturn will disappear behind the Sun shortly, but Mars hangs around in the evening sky for a few more months, but always low and easy to miss.
Mercury is elusive but here it is, showing up as a speck over the skyline of Calgary, as it begins its best evening appearance of the year, rising a little higher into the twilight sky each night for the next few evenings.
To find it, follow the line down from the Moon and then bright Jupiter and Venus at upper left and continue that line to the lower right. Just to the right of the tallest building (the new Bow tower) and just above the rooftops there’s a tiny dot of light. That’s the inner planet Mercury. It’ll get higher in the first week of March but not by much. Mercury is bright. It’s just not very high and is easy to miss.
But with Mercury coming into view, and with Venus and Jupiter so prominent now in the evening, and Mars now bright in the east after sunset – look for a red star – we have a nice array of 4 naked eye planets across the sky at once. Saturn comes up later after midnight now. So you can see 5 naked eye planets in one night.
