Located 63 million light-years away in the constellation Coma Berenices, M91 is part of the Virgo cluster of galaxies – and if you zoom in and explore this image, you’ll find many other galaxies surrounding it, and also far in the distance beyond it.
Granted this is only a portion of it, but for the life of me I don’t see a pelican in this thing. But, it’s still pretty. I processed this object two ways: using the “Hubble palette” that maps red, green, and blue to Sulfur, Hydrogen, and Oxygen emissions (that results in the pretty blue one)…
Spent a couple of nights imaging these distant galaxies; the spiral in the upper-left is NGC2336, and the other is IC467. Galaxies this faint and distant generally don’t have catchy names! NGC2336 is 100 million light-years away. Think about that – you’re looking 100 million years in the past. The light we captured started its…
I’ve wanted to image the “Fox Fur Nebula” for awhile now – it’s pretty obvious where it is in this image! Within the same field of view is the Cone Nebula (near the bottom.) It’s all an area of gas within the Christmas Tree Cluster, which is an open cluster of stars that kind of…
In these short summer nights, I want to take advantage of every moment of darkness. Right now, the galaxy M100 is up in the hours before midnight, and the “Tulip Nebula” – formally SH2-101 – rises just as M100 sets. So for this past week, I’ve been imaging both objects. But no more clear skies…
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…
I trained my telescope at this pair of nebulas in Orion for a total of 10 hours. On the right is the iconic Horsehead nebula – actually a dark cloud of gas in front of the illuminated nebula behind it. To the left is the Flame Nebula. In between, in the upper-left, is the bright…
