The Whirlpool Galaxy
The Whirlpool Galaxy (M51) appears to be sucking the life out of its companion, NGC 5195. While these galaxies are interacting, they’re not actually connected right now – it just looks that way.

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…
The galaxy M106 is an interesting one; it’s large and relatively bright – about the same size as Andromeda. And it’s in a busy part of the sky, within Canes Venatici, with lots of galactic neighbors. This image has been enhanced with Hydrogen emission data; that’s what the red dots and tendrils are. There’s one…
Our new home has clear views of the sky down to about 15 degrees from the horizon; which means some objects that are normally considered only visible from the Southern hemisphere just peek above our trees for a few hours. One such object is the galaxy Centaurus A; it’s an odd galaxy that looks like…
There are a lot of stars in this picture; the gases of the Wizard Nebula (formally SH2-142) are the birthplace of those stars, and more are being created even now. It’s located about 7,200 light-years away, and is extremely dim – it took over 9 hours of exposure time to capture this image. Your ability…
Comet C/2021 A1 (Leonard) is approaching the Sun – right now it’s only above the horizon in the early morning hours, but soon it will loop around and be visible in the evening. As of right now, you need a telescope to see it – it’s too dim even for binoculars. But it’s possible it…
The Rosette Nebula is about 5,000 light-years away in the constellation Monoceros. It’s the birthplace of the cluster of stars it contains. While it doesn’t look much like a Rose in this view, the false-color narrowband image below brings out more of its structure. 7 1/2 hours of total exposure time, on New Year’s Eve…
