Markarian’s Chain

This galaxy is truly one of a kind, at least among that galaxies we have found. It’s a “polar ring galaxy,” probably the result of an unusual collision that left the core lenticular galaxy surrounded by the disk of another galaxy that it merged with. It’s a small, dim object, and just barely detectable from…

Last night marked Jupiter’s “opposition” – this is the time of year where Jupiter is at its closest point to Earth, and it’s at its biggest and brightest. By a stroke of luck, we had unusually clear skies for this event, and its moon Io was also crossing in front of Jupiter! You can see…

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…

Formally this nebula is called vdB93, but more commonly it is a part of the “seagull nebula.” The larger nebula really does look like a flying bird, but it’s a little too big to fit in the field of view of my telescope – so I focused instead on its “head” where most of the…

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.

We recently obtained a new telescope for observing the planets, and we had our first good conditions for planetary imaging this morning! This is the best image of Jupiter I’ve ever gotten, and I’m hopeful that it will be even better once it gets closer to Earth in a couple of Months. Saturn’s not looking…
