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…

We kept the ‘scope out all day, and observed a smaller flare seen across from the big ones turn into a…

Formally SH2-155, the Cave Nebula lies about 2,400 light-years away within the constellation Cepheus. It’s part of a much larger region of gas and dust (called a molecular cloud). This region is mostly ionized Hydrogen, but there’s just enough Oxygen – blue in this image – to make for a pretty picture. Capturing that Oxygen…

A nebula that looks like its name! Formally SH-308, this bubble of gas 60 light-years across is blown out by a hot Wolf-Rayet star at its center. It’s about 4500 light-years away in the constellation Canis Majoris. It’s quite dim, but if you could see it with bionic vision or something, it would be larger…
