The “Leo Trio” of galaxies

There are two different clusters of galaxies in this image – the large galaxy you see is NGC 7331, part of the “Deer Lick Galaxy Group.” The smaller galaxies you see surrounding it (sometimes called “The Fleas”) are actually about ten times further away than NGC 7331. In the corner, you’ll see “Stephan’s Quintet,” a…

M13, the great globular cluster in Hercules. You can see some of its interesting neighbors, including the galaxy NGC 6207 in the lower-left. While M13 itself is 25,000 light-years away just above our galactic plane, NGC 6207 is 37 million light-years distant. About halfway between the two, the galaxy IC 4617 is also visible –…

This image was something of a happy accident – I spent a night capturing narrowband data on M16, the Eagle Nebula (home of the famous “pillars of creation”.) Of course I had to try reproducing the iconic Hubble image as best I could, but the color palette they use results in big, ugly, magenta-colored stars….

It doesn’t take much imagination to see a ghost leaving a trail of ectoplasm in this cloud of Hydrogen gas, lit up by the bright star Navi. To keep with a spooky and ethereal theme, I photographed this object in monochrome using only a Hydrogen-alpha filter.

The three galaxies in the constellation Leo (M65, M66, and NGC3628) are about 31 million light-years away. Each one is being seen from a different angle; the one viewed edge-on is also known as the “Hamburger Galaxy”. Each has been interacting with each other, and distorting the shapes of these galaxies through the complex dance…

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…
