The Moon

This is M27, the “Dumbbell Nebula,” about 1600 light-years away. It’s what’s called a planetary nebula – not because it has anything to do with planets, but because early observers confused them for planets. In reality it’s far more interesting. This is what’s left over when a medium-sized star runs out of Hydrogen to fuse,…

This is NGC281, or the “Pac-Man” nebula. I think it’s one of those objects that might look a little like its name if you’re viewing it through a big telescope in a dark sky, but takes on a totally different character in long-exposure, narrowband images such as this. This is a total of 13 hours…

It’s been really cloudy lately in Central Florida, so instead of imaging from my driveway, I’ve tried using remote observatories. This particular image was taken using a telescope in Australia, using a service called telescope.live. This is the “Coalsack nebula”, a dark cloud of gas obscuring the Milky Way in the Southern hemisphere. We’re looking…

Johan Bode discovered both Bode’s Galaxy (M81, on the left) and the Cigar Galaxy (M82, on the right.) Look closely and you’ll see many other, more distant galaxies in the background as well.

Every year I try to take a better image of M81, Bode’s Galaxy. It’s located about 12 million light-years away, which is unfathomably far but close by galactic standards. Look closely, and you’ll see a faint splotchiness in the background. This is the Integrated Flux Nebula (IFN,) composed of gases that lie just outside of…

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…
