AKA Abell 1656. There are tens of thousands of galaxies in this portion of the sky; almost everything in this image is an entire galaxy filled with hundreds of millions of stars. Whoah. And they’re hundreds of millions of light-years away. Click and zoom in to explore them all.
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…
Imaged in narrowband filters from my suburban driveway. This object lives up to its name with the right color mappings!
These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…
M13, the great globular cluster in Hercules. You can see some of its interesting neighbors, including the galaxy NGC 6207 in the lower-left. While M13 itself is 25,000 light-years away just above our galactic plane, NGC 6207 is 37 million light-years distant. About halfway between the two, the galaxy IC 4617 is also visible –…
As Halloween draws closer, this seems like an appropriate object to image: the “Witch’s Broom” nebula! Although to be honest, that bright star (Cygnus 56) looks more like an eye on some sort of fantastical, cosmic creature to me. In reality, it’s part of the larger Veil Nebula, which is a huge supernova remnant 1,400…
This is a weird little cluster of galaxies – there are four in all, and each one is completely different. There’s a weird, S-shaped one that must have been messed up by its neighbors in the past, a somewhat normal-looking spiral galaxy, and elliptical, and another one that’s viewed edge-on. Galaxies that have interacted with…
