A bubble of glowing gas blows away from an ancient dying star, next to a cluster of new stars in Gemini.
This image, from a week ago, captures contrasting stages in the life of a star.
At left is a crescent-shaped bubble of gas called IC 443, or the Jellyfish Nebula, billowing away from the site of an ancient supernova explosion, when a giant star ended its life in a blast thousands of years ago. Estimates put its age as between 3,000 and 30,000 years.
At upper right is the bright open star cluster, Messier 35, a gathering of hundreds of comparatively new stars at the beginning of their lives. M35 lies 2,800 light years away, close enough that its stars are nicely resolved in my photo and in any small telescope. M35 is one of the showpieces of the winter northern sky.
Just below M35 you can see a fuzzy glow. It’s another star cluster, NGC 2158. However, its great distance of 11,000 light years makes it appear as a small, partially-resolved glow, a nice contrast in clusters near and far.
This image focuses on IC 443, sitting between the stars Eta (right) and Mu Geminorum. The field is filled with other faint nebulosity, all part of the cycle of star birth and death.

The Amazing Sky 
I am in awe! ❤
An amazing composition Alan. Inspiring.
My close-ups of M35 certainly doesn’t show it’s located in, galactically speaking; “An nebulosity filled, upscale neighbourhood within an urban renewal scheme”.
If the clouds ever break & it’s not under -15 C, I think I’ll return to M35 with a wider angle view in mind.

Hi, yes, that’s why I like the wider field images through telescopes, to show the object in context, rather than in-your-face close ups. Thanks!
Alan,
The colors and details are fantastic. Was this shot through one of your telescopes?
Yes, through the 92mm TMB apo refractor, working at f/4.4. Both are stacks of 10 x 6 minute exposures.
