M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.
This image contains a few things! At the bottom is the Cone Nebula, at the upper-right is the “Fox Fur Nebula”, and in the middle is the “Christmas Tree” star cluster… you have to flip the image upside down to see that one. It’s a gorgeous region of active star formation in the constellation Monoceros….
As Halloween draws closer, this seems like an appropriate object to image: the “Witch’s Broom” nebula! Although to be honest, that bright star (Cygnus 56) looks more like an eye on some sort of fantastical, cosmic creature to me. In reality, it’s part of the larger Veil Nebula, which is a huge supernova remnant 1,400…
Here we have another globular cluster: M53. You don’t see this one imaged too often, but it’s still quite pretty. I’ve never met a globular cluster I didn’t like. It’s one of the more distant globular clusters in our galaxy, about 60,000 light-years away.
This galaxy is truly one of a kind, at least among that galaxies we have found. It’s a “polar ring galaxy,” probably the result of an unusual collision that left the core lenticular galaxy surrounded by the disk of another galaxy that it merged with. It’s a small, dim object, and just barely detectable from…
The Pelican Nebula frankly isn’t a very attractive object as a whole, but if you crop it down to its heart, there’s a lot of interesting stuff going on. Look for little puffs in the image, or areas with spikes coming out of them. Those are Herbig-Haro objects – stars that are still in the…
Had a couple of clear nights recently, and trained the ‘scope at the Rosette Nebula again. By combining this year’s data with last year’s, I created an image with a total 27 hours of exposure time! The Rosette Nebula is about 5,000 light-years away within the constellation Monoceros, and is the birthplace of the cluster…
