Triangulum Galaxy

The Cocoon Nebula in Cygnus is a compact cloud of Hydrogen, lit up by the bright star in its center. Dust lanes can also be seen across it, obscuring the ionized Hydrogen gas behind them. This object is best imaged during the heart of Summer, which means really challenging conditions here in Florida. High humidity,…

These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…

This one’s also known as the “Silver Sliver” Galaxy, or more formally NGC 891. It’s about 30 million light-years away, well beyond our own local group. It’s thought to be quite similar to our own Milky Way! What I really geek out on, though, is the wider views here – there are so many other…

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,…

There’s a big cluster of galaxies within Virgo; it’s just filthy with them. People usually image a different part of it, but I found another interesting area that’s often overlooked. The grand-design spiral at the bottom is NGC5364; it’s about 55 million light-years away. The annotated image identifies its buddies.

The main galaxies in this image go by the unassuming names of NGC5033 and NGC5005 (5033 is the larger spiral galaxy.) They’re within a constellation named Canes Venatici, or “the hunting dogs.” Look closely, and you’ll spot a few other galaxies – some large but more distant, and some that are just really small and…
