Welcome back to Messier Monday! In our ongoing tribute to the great Tammy Plotner, we take a look at that Great and most brightest of nebulae – the Orion Nebula!
During the 18th century, famed French astronomer Charles Messier noted the presence of several “nebulous objects” in the night sky. Having originally mistaken them for comets, he began compiling a list of them so that others would not make the same mistake he did. In time, this list (known as the Messier Catalog) would come to include 100 of the most fabulous objects in the night sky.
One of these objects is the Orion Nebula, a diffuse nebula situated just south of Orion’s Belt in the Orion constellation. Located between 1,324 and 1,364 light years distant, it is the closest massive star forming region to Earth. Little wonder then why it is the brightest nebula in the night sky and can be seen on a clear evening with the naked eye.
Description:
Known as “The Great Orion Nebula,” let’s learn what makes it glow. M42 is a great cloud of gas spanning more than 20,000 times the size of our own solar system and its light is mainly florescent. For most observers, it appears to have a slight greenish color – caused by oxygen being stripped of electrons by radiation from nearby stars.
