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.
Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away. These images were taken over the span…
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…
Our new house has plenty of land, reasonably dark skies, and a reasonable homeowner’s association… so of course I had to try building an observatory! It may sound crazy, but it does offer a lot of advantages: I no longer have to set up my telescope, wait for dark, polar align it, and run a…
Every year I try to take a better image of M81, Bode’s Galaxy. It’s located about 12 million light-years away, which is unfathomably far but close by galactic standards. Look closely, and you’ll see a faint splotchiness in the background. This is the Integrated Flux Nebula (IFN,) composed of gases that lie just outside of…
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…
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…
