Here’s my latest image of the Bubble Nebula in the Hubble Palette. This is such a cool area of the sky, and I never get tired of imaging it. Eventually, I’d like to do some more higher resolution work of it, but this data from October with my TMB130 will have to do for now.
As always, C&C are welcome and encouraged! Thanks for looking!
The Bubble Nebula is an emission nebula in the constellation Cassiopeia and lies some 11000 light years away. The bubble is 10 light years in diameter and is formed by the strong stellar wind of a large hot star at the 11 o'clock position in the bubble. This wind is causing the bubble to expand at roughly 6 million miles per hour. This star is 2 million years old and will likely go supernova within 10-20 million years. Surrounding the bubble are expansive molecular clouds that are also excited by the hot central star.
