Orion Nebula, Messier 42

$65.00 $52.50

The Orion Nebula, also known as Messier 42, the nebula’s glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1,500 light-years away. The Orion Nebula offers one of the best opportunities to study how stars are born partly because it is the nearest large star-forming region, but also because the nebula’s energetic stars have blown away obscuring gas and dust clouds that would otherwise block our view – providing an intimate look at a range of ongoing stages of starbirth and evolution.
