Description

The Eagle Nebula is a young open cluster of stars in the constellation Serpens. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation.

Evidence from the Spitzer Telescope originally suggested that the pillars in M16 may already have been destroyed by a supernova explosion. Hot gas observed by Spitzer in 2007 suggested that the area was disturbed by a supernova that exploded some 8,000 to 9,000 years ago. Due to the distance of the nebula, the light from the supernova would have reached Earth between 1,000 and 2,000 years ago. The more slowly moving shock wave from the supernova would have taken a few thousand years to move through the nebula and would have blown away the delicate pillars.

However, in 2014 the Pillars were imaged a second time by Hubble, in both visible light and infrared light. The new images being 20 years apart provided a new, detailed account of the rate of evaporation occurring within the pillars. It was later discovered that there in fact was no supernova explosion within them, and it is estimated they will be around for at least 100,000 years longer.

There is always a story behind every imaging night, I am just grateful that I was able to get enough data to process this. Here's my SHO version of the Eagle Nebula. Comments and feedback are much appreciated.

Clear Skies!
