The Whale and the Hockey Stick

There are two different clusters of galaxies in this image – the large galaxy you see is NGC 7331, part of the “Deer Lick Galaxy Group.” The smaller galaxies you see surrounding it (sometimes called “The Fleas”) are actually about ten times further away than NGC 7331. In the corner, you’ll see “Stephan’s Quintet,” a…

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…

Taken just prior to Halloween in 2018, the southeastern knot of the Eastern Veil Nebula takes on a ghostly appearance when imaged in the Hubble palette with narrowband filters.

An interesting emission nebula 30 light years across. Imaged with narrowband filters.

Granted this is only a portion of it, but for the life of me I don’t see a pelican in this thing. But, it’s still pretty. I processed this object two ways: using the “Hubble palette” that maps red, green, and blue to Sulfur, Hydrogen, and Oxygen emissions (that results in the pretty blue one)…

Highlighted here is a recently discovered supernova in the galaxy M61, over 50 million light-years away! This exploding star outshines the entire core of its own galaxy, and many of the much closer stars seen within our Milky Way. The sheer power of this stellar explosion is unfathomable. It’s 50 million light-years away, which means…
