Coma Berenices Galaxy Cluster

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…

Messier 88, within the constellation Coma Berenices, is part of the nearby Virgo cluster of galaxies. And by “nearby”, I mean 50-60 million light years away! The light we’re seeing from this galaxy originated from the time of the dinosaurs. Telescopes are really time machines. There are many other galaxies surrounding M88, both smaller and…

This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…

M17 is commonly known as the Swan Nebula or the Omega Nebula. From this angle, I think it looks more like a crab – but “Crab Nebula” was taken! Shot over a hazy summer night, with narrowband filters for the gases of the nebula itself, and RGB natural-color filters for the stars. Presented processed with…

Imaging deep sky objects from a suburban driveway forces one to find ways to deal with light pollution. Light pollution is the enemy of astronomers – but in reality, there are ways around it. Some of the most beautiful objects in the cosmos are called emission nebula. They are clouds of gas, often where new…

Domey McDomeFace’s days are numbered, I’m afraid! Our property is up for sale, and hopefully its new owner will continue to use it to produce amazing images of their own. Meanwhile, I’m taking advantage of every clear night I can, while we’re still here. Here’s one of my favorite objects: “Thor’s Helmet” or NGC2359. Like…
