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 into a white dwarf, slowly burning what’s left of it at the nebula’s center. Our own sun is expected to do the same in a few billion years.
A spiral galaxy almost 40 million light-years away, viewed edge-on. The dust lane in the center of its disk, and central bulge are clearly visible. A couple of its smaller, satellite galaxies can also be seen here.
Here’s another galaxy with no nearby neighbors, and no catchy nicknames either: NGC 3344. It’s about 22.5 million light-years away within the constellation Leo Minor. Although it doesn’t get the love it deserves, it’s a glorious face-on barred spiral galaxy that’s about half the size of our own Milky Way. Explore the space around it,…
There’s a comet in the sky! They don’t appear this bright very often, so don’t miss what could be a once-in-a-lifetime chance to see a comet with your own eyes. It’s tough to spot here in suburbia with your eyes, but it’s easy to see with binoculars. Its official name is C/2020 F3 NEOWISE. Just…
This is planetary nebula PK205+14.1, but its common name “The Medusa Nebula” rolls off the tongue a little better. About 1500 light-years away within the constellation Gemini, you’re seeing the gas blown off by a small star that ran out of fuel, and blew up into a red giant – later to end its life…
Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner! Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.
This portion of the Veil Nebula, commonly called the “Witch’s Broom,” is part of a larger shell of gas known as the Cygnus Loop. It’s gases blown off from a supernova that exploded 10,000 to 20,000 years ago! The rich red and blue colors are real; this is not a false color image. Shot over…
