Globular Cluster M3

M13 is one of the most photogenic and popular globular clusters, and it’s pretty easy to see with nothing more than a pair of binoculars if you know where to look! But it’s even prettier with a long exposure – this is about 3 hours of exposure time. Blow it up to full size, and…

This is the Helix Nebula, sometimes also called the “Eye of God” or the “Eye of Sauron”. It’s a planetary nebula, formed by a star blowing off its outer layers of gas before collapsing into the white dwarf you can see at its center. This is thought to be the ultimate fate of our own…

Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away. These images were taken over the span…

This is a somewhat obscure target; at 46 million light-years distant, it’s hard to capture much detail on it from Earth. But that’s what makes it interesting and challenging! Located within the constellation Ursa Major, this is a flocculent spiral galaxy notable for its massive central core. Look around in the background, and you’ll find…

The Whirlpool Galaxy (M51) appears to be sucking the life out of its companion, NGC 5195. While these galaxies are interacting, they’re not actually connected right now – it just looks that way.

This is a weird little cluster of galaxies – there are four in all, and each one is completely different. There’s a weird, S-shaped one that must have been messed up by its neighbors in the past, a somewhat normal-looking spiral galaxy, and elliptical, and another one that’s viewed edge-on. Galaxies that have interacted with…
