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.
Imaged in narrowband filters from my suburban driveway. This object lives up to its name with the right color mappings!
Both on Earth, and in space! While we prepare for a year or two in California, I trained Scopey von Scopington on the California Nebula for a few nights. Pretty obvious how it got its name! This is a two-panel mosaic, consisting of narrowband SHO data for the nebula and broadband RGB for the stars….
This is M27, the “Dumbbell Nebula,” about 1600 light-years away. It’s what’s called a planetary nebula – not because it has anything to do with planets, but because early observers confused them for planets. In reality it’s far more interesting. This is what’s left over when a medium-sized star runs out of Hydrogen to fuse,…
This is the Tulip Nebula in Cygnus, but see that shell-like structure just above it, to the right a little? That’s the bow shock wave of Cygnus X-1, a stellar-mass black hole! It’s one of the most powerful X-ray sources in the sky – but don’t worry, our atmosphere protects you from it. 20 hours…
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.
This image really blows my mind – this is the reflection nebula NGC1333 in Perseus. The blue part is reflected gas and dust from the star that’s lighting up – that’s nothing too unusual. But check out the little red blobs above it. Many of those are “Herbig-Haro” objects, formed by jets spewing out from…
