The Bubble Nebula

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…

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 –…

Our new home has clear views of the sky down to about 15 degrees from the horizon; which means some objects that are normally considered only visible from the Southern hemisphere just peek above our trees for a few hours. One such object is the galaxy Centaurus A; it’s an odd galaxy that looks like…

I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope. But through 2 hours of total exposure time, the colors do emerge, and…

It’s been awhile since I attempted Jupiter and Saturn… years, in fact. But last night was too good to pass up. Jupiter is just past its opposition, and it’s one of its closest approaches to Earth ever. There wasn’t a lot of turbulence in the air late last night, the Great Red Spot was out,…

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…
