The Whale and the Hockey Stick
It’s not the title of a children’s story – it’s a pair of galaxies 30 million light-years away that look like, well, a whale and a hockey stick. Officially their names are NGC 4631 and NGC 4656.

Located about 1,300 light-years away, the Iris Nebula is a reflection nebula – unlike most of the nebulas on this site, it’s not made of ionized gases emitting light of their own. It’s just starlight reflecting off clouds of dust. Reflection nebula are harder to image in light-polluted skies, since the narrowband filters we use…
This is the Christmas Tree Cluster (turn the picture upside down and you might see it!) But the real focus here is the Cone Nebula at the bottom of the image, and the Fox Fur Nebula in the upper-right. Lots of red Hydrogen gas here being ionized by the young stars it formed. Also visible…
It’s a good thing galaxies don’t have feelings; they’re just collections of billions of stars. Because NGC 2903 would need therapy. It has no cute nickname like other galaxies; it’s just NGC 2903. And it has no galactic neighbors; most galaxies are gravitationally bound to other galaxies in their local group or cluster, but NGC…
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…
This is IC342, located about 10 million light-years away. If it were anywhere else in the sky, it would be visible to the naked eye – but it lies behind the disk of our Milky Way galaxy, obscuring the view. This image is the result of 22 hours of total exposure time to try and…
M17 is commonly known as the Swan Nebula or the Omega Nebula. From this angle, I think it looks more like a crab – but “Crab Nebula” was taken! Shot over a hazy summer night, with narrowband filters for the gases of the nebula itself, and RGB natural-color filters for the stars. Presented processed with…
