Mars is now shining brightly in the evening sky, as close and as bright as it has been since 2005.
Look southeast to south after dark and you’ll see a brilliant reddish “star.” That’s Mars, now at opposition, and retrograding slowly westward each night through Scorpius into Libra.
My image above captures Mars set in the entirety of the northern spring sky, complete with the arch of the Milky Way, twilight glows to the north (at left), some satellite trails …
… and Mars itself as the brightest object just right of centre shining above the landscape of Dinosaur Provincial Park.
Just to the left of Mars is Saturn, while below both is the star Antares in Scorpius, for a neat triangle of objects. Jupiter is the bright object in Leo at far right.
Technical: I shot the lead image on the evening of May 25. It is a 360° and horizon-to-zenith panorama stitched from 44 images, taken in 4 tiers of 11 panels each, shot with a motorized iOptron iPano mount. I used a 35mm Canon lens at f/2.8 for 30-second exposures with the Canon 6D at ISO 6400. I stitched the images with PTGui. The original image is a monster 32,500 pixels wide by 8,300 pixels high.
I shot the panorama above earlier in the evening, when Mars and Saturn were just rising in the southeast at left, and the sky to the northwest at right was still bright with twilight.
This shows the geometry of Mars at opposition. It lies opposite the Sun and is so rising at sunset and directly opposite the sunset point. The Sun, Earth and Mars are in a straight line across the solar system with Earth in the middle and as close to Mars as we get.
Actual date of opposition was May 22 but Earth is closest to Mars on May 30. That’s when it will look largest in a telescope. But to the unaided eye it appears as a bright red star.
Whether with eye or telescope, have a look!
