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.
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…
Now that our new backyard observatory is up and running, and we’re under darker skies than in our previous home, I’m revisiting some galaxies I’ve imaged before to see how things compare. Galaxies are tough… any amount of light pollution or moonlight really limits your ability to capture faint, wispy details. But the less light…
If you look at the constellation Orion in the winter night’s sky, the center of Orion’s “sword” is not a star at all – it is the brightest nebula in our sky, M42 or the Great Nebula of Orion. Sitting right on top of it is technically another nebula designated M43, and above that is…
Imaged in narrowband filters from my suburban driveway. This object lives up to its name with the right color mappings!
Globular clusters are mysterious objects – they are dense clusters of stars, some containing hundreds of thousands of them. And they’re not within the plane of the Milky Way galaxy; they are scattered around it. How they formed is a bit of a mystery. Did they form with our galaxy, or are they the cores…
Narrowband image of the cone-shaped absorption nebula in front of the brighter emission nebula in this interesting region of the Christmas Tree Cluster, about 2,700 light-years away.
