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,…
Formally IC1396, this cloud of interstellar gas and dust is thought to be an active site of new star formation. And with a little imagination, it kind of looks like an elephant’s trunk. There’s more to it than you see here, but I tried to get an interesting framing. From this angle we see a…
On December 21, 2020, something really special happened in the sky: Jupiter and Saturn had an approach so close that it only happens every 800 years or so. They were so close in the sky that to the unaided eye, they looked like a single, bright star. This led many to proclaim it to be…
Also in Hercules, M92 is often passed over for its larger and more dazzling neighbor, M13. But M92 is pretty in its own way! It’s also one of the oldest globular clusters in our galaxy (over 11 billion years old) and has some very interesting background galaxies around it too.
The “Jellyfish Nebula” is a supernova remnant in the constellation Gemini, about 5,000 light-years away. It’s the gas blown off from a star that exploded, sometime between 3,000 and 30,000 years ago – we’re really not sure when it happened. But it makes for quite a spectacle! I was plagued with technical issues while capturing…
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…
