Cone Nebula

This edge-on spiral is around 40 million light-years away within the constellation Coma Berenices. Lots of satellite and background galaxies to explore around it! Zoom in, and travel back in time – hundreds of millions of years.

Located about 1,300 light-years away, the Iris Nebula is a reflection nebula – unlike most of the nebulas on this site, it’s not made of ionized gases emitting light of their own. It’s just starlight reflecting off clouds of dust. Reflection nebula are harder to image in light-polluted skies, since the narrowband filters we use…

The three galaxies in the constellation Leo (M65, M66, and NGC3628) are about 31 million light-years away. Each one is being seen from a different angle; the one viewed edge-on is also known as the “Hamburger Galaxy”. Each has been interacting with each other, and distorting the shapes of these galaxies through the complex dance…

The Dumbbell Nebula (M27) is what’s called a planetary nebula – but it has nothing to do with a planet. This shell of gas was blown out by a dying star; once it started to run out of Hydrogen to burn, it expanded and blew out the gases you see here. The star then collapsed…

Here’s my latest image of the “Bubble Nebula”, one of my favorite objects in our galaxy. That blue “bubble” is a shell of gas pushed out by the stellar wind of the bright star just right of its center. It’s a big star, 10-20 times larger than our sun. Its radiation is also illuminating and…

Every year I try and do a better job of capturing and processing the Bubble Nebula in Cassiopeia. Here’s this year’s attempt. The Bubble Nebula is one of my favorite objects. Not only is it interesting scientifically (the bubble is the stellar wind of a hot O-type star blowing away the surrounding gases,) it’s also…
