Tonight's Sky for March 29: Moon Meets Mars and Saturn, Take 2

It's the second close meeting of the Moon, Mars, and Saturn of the month. At the start of the month, there was a similar meet up but, come the end of the month, things are going to look quite different. Why? Mars has been retrograding, or appearing to move backwards relative to the stars (this is an optical illusion caused by Earth passing the slower Mars as both planets travel around the Sun), all month. End result: Mars and Saturn are a lot closer together than they were just at the start of March. Additionally, Antares, whose name means 'rival of Mars,' undoubtedly due to the star's red color, is nearby, too.
