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.

Part of our Local Group of galaxies, the Triangulum Galaxy (M33) is about 3 million light years away and the most distant object visible to the naked eye under dark skies.
As we enter summer and the Earth starts pointing us back into the plane of the Milky Way and its many nebulas, we’re nearing the end of globular cluster season. M5 seems a fitting one to end on this year; there’s nothing terribly remarkable about it, other than I think it’s pretty. It’s located about…
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…
Located 63 million light-years away in the constellation Coma Berenices, M91 is part of the Virgo cluster of galaxies – and if you zoom in and explore this image, you’ll find many other galaxies surrounding it, and also far in the distance beyond it.
This was intended to just be an image of the galaxy M77 in Cetus, but quite a few other galactic photobombers showed up! The annotated image below guides you to the brighter galaxies in this image, but click on it to expand it, and you’ll find many other ones as well that are incomprehensibly distant.
Our new house has plenty of land, reasonably dark skies, and a reasonable homeowner’s association… so of course I had to try building an observatory! It may sound crazy, but it does offer a lot of advantages: I no longer have to set up my telescope, wait for dark, polar align it, and run a…
