Happy New Year !

We had the most spectacular lunar halo tonight. (I usually post single exposures, but here the face of the Moon is from a separate shot — it was just too bright otherwise. This is much closer to how it looked.)

A collage of some of my simulations of galaxy interactions and real observed galaxies from some Sloan Digital Sky Surveys images. Thinking of re-running the best ones at much higher resolution with ALL THE PHYSICS

Has it hit or will it hit tomorrow? Prediction models of the recent #solarstorm launch disagree! NOAA/SWPC says it already hit, while NASA says impact will be late Jan 18. Either way, expect mild #aurora at high latitudes; only minor issues with #emergency radio & #GPS reception!

Spiral galaxies look like pinwheels, but their arms are actually density waves that trigger star formation as they go. A spiral galaxy is more a *pattern* than a single object. burro.cwru.edu/Academics/Astr…

Caroline Herschel was a German astronomer born in 1750. She discovered a new galaxy, an asteroid, and five comets. She also compiled a star catalogue and a catalogue of nebulae 🔭🌌

David Blanchflower BSc Got to see Neowise through aome aurora that washed it out , Aurora only lasted 20 minutes. Beautiful comet looking through binoculars.

What an amazing weekend up north! Got comet Neowise in Mackinaw City and Wilderness State Park. #cometNEOWISE #NeowiseComet #NEOWISE #MilkyWay #Astrophotography #SonyAlpha #BeAlpha #PureMichigan #StormHour Jim Cantore James Spann Reed Timmer (parody) Ginger Zee Dr. Tamitha Skov Pure Michigan

As dark skies have returned I thought I’d venture out of the solar system for a change and image something a little further away. Here’s the beautiful Double Cluster in Perseus imaged from #London last night. #astronomy #astrophotography #canonphotography #space
