The “Leo Trio” of galaxies

If you point your telescope outside of the Milky Way, you’re almost guaranteed to pick up very distant galaxies, because there are just so many of them out there. This patch of sky inside Cancer is a cluster of galaxies called Abell 671. If you click the image and look at it full size, you’ll…

A wider shot of the Eagle Nebula, with the famous “pillars of creation” in its center.

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…

This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…

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…

This morning, my cat woke me up at 3 AM, and I noticed it was clear outside. But, the sun would start rising in just a couple of hours, so doing some super-long-exposure shot of a faint nebula wasn’t in the cards. However, globular clusters don’t take long to image, as they are relatively bright…
