Glenn's Astrophotography




M42, M43 and NGC 1977

M42 also know as "The Great Nebula in Orion" is one of the most viewed and photographed objects in the night sky. M42, in the constellation of Orion is the brightest nebula in our sky and is visible to the naked eye as the middle fuzzy star-like object in Orion's Sword. At its core is a nest of star birth activity, which excites the atoms in the surrounding hydrogen cloud to the point of luminescence.

To the immediate left in this image is a nearly circular emission nebula formation, known as M43, which is partially obscured by the dust and gas in M42.

The left-most somewhat bluish object in this image is the reflection nebula NGC 1977, also known as the Running Man Nebula because of its unique shape.

This group of objects is approximately 1500 light-years from Earth and about 30 light years across.

Recent images from the Hubble Space Telescope of this region have revealed many stars in various stages of formation. The HST images have also revealed proto-planetary disks around many of the young stars which further verify the theories of planetary formation around stars.
