The joys of stargazing at southern latitudes! Here’s a shot from this morning, May 2, 2011, of the gathering of four planets now coming together in the pre-dawn sky. From Canada, you won’t see this well at all. The planets will be hugging the horizon and lost in the twilight. But from here in Chile, at a latitude of 23° south, the planets are arranged vertically straight up from the horizon. Over the next couple of weeks the planets will converge as Venus and Mercury drop down to meet Jupiter and Mars – they’ll be tightest, within 6° of each other on the mornings of May 11 and 12, when Venus and Jupiter, the two brightest objects here, will be closest together.
It was very neat watching them rise this morning over the Andes, first brilliant Venus popping over the ridge, then fainter Mercury, the Jupiter, and finally, at the bottom here, Mars. Venus and Mercury pair at top, and Jupiter and Mars are together at bottom.
The conical peak at left is 5,900-metre (19,400-foot) Licancabur, an extinct volcano, one of many along the line of the Andes. I shot this from just outside our dining room at the Atacama Lodge near San Pedro de Atacama. It was the finale of an all-night session shooting the Milky Way in stills and time-lapse. All the gear worked great and the raw images look fabulous. More to come!
