Starship Asterisk*

Ann wrote:That's a splendid, fantastic image, Marco Lorenzi! It is amazingly beautiful. The colors are absolutely stunning, some of them vivid, some of them subtle. And it is the first time ever that I have actually seen emission nebula Sharpless 34 (the nebula at upper left) in a picture of the Lagoon and Trifid region. I wonder what causes this nebula. Could it be the combined ultraviolet light from all the hot bright stars in this area?

I had indeed discovered Sharpless 22 before. That nebula is centered on O type star HD 162978.

Anyway, that is a brilliant, lovely picture! Thank you, Marco Lorenzi!

Thanks Ann, you are very kind! Colors in this part of the sky are really amazing, I am happy to have been able to get them in their glory

IC443 - Supernova Remnant
http://www.schursastrophotography.com/astromain.html
Copyright: Chris Schur This extremely faint object in near the feet of Gemini is the result of a star exploding several thousand years ago, in creating a nebula that was formed the same way the more famous and well known Veil nebula in Cygnus came about. Spanning over a half a degree in extent, the progenitor star is located within the lower brighter portion. The brilliant star is Eta Geminorium "Propus", and is 3.3rd magnitude of a very orange type M3. South is up in this image.
