Today’s Astronomical Events – February 24th, 2015

Observers on opposite sides of the world get to see events on opposite sides of the day on the 24th. Mercury is at greatest western elongation, meaning that it is best placed for observation in the pre-dawn twilight sky. Unfortunately, it will be too close to the horizon for observers in the United Kingdom and North America. However, those in the northern hemisphere can still enjoy the conjunction of Venus and Mars in the evening twilight. The pair are slowly moving apart but still appear close together. Take another look over the next few nights to see the gap between them widen.
