M13 is a globular cluster located about 24 kly away in the constellation of Hercules.

One of the more spectacular globular clusters visible in the northern hemisphere, it is relatively easy to find once you find the constellation Hercules. Looks good even in binoculars. #astronomy

Good article! I would add that NOAA has a predictor website. Tomorrow looks good:

Scroll down to the 30 minute predictions and refresh often. Things can change quickly.

M28 is a globular cluster located about 18 kly away in the constellation of Sagittarius.

As with most globular clusters there appears to be no active star formation as the stars in the cluster are all cool, older red stars with no young blue stars. #astronomy

Our Observers’ Group meeting this evening at our club observatory was sparsely attended due to overwhelming clouds. A few others joined in via Zoom. 🔭 #astronomy

🦇Here’s the truth: Alberta’s bats are working night shift every single day to keep our forests and crops healthy.
If they disappeared, we’d feel it fast - more pests, more damage, more pesticides.
Small animals. Big impact.

Has anyone observed STEVE from Alaska? This is just a soft ask for now, but I am compiling a list of events to study further, and if you have a photo of STEVE from Alaska (specifically near Fairbanks), feel free to comment it below with a date, time, and location!

The Peekskill meteorite car belonged to my mother’s housekeeper.

She called me that day and said “A meteorite crashed through my housekeeper’s car”
I thought it was just a bid for attention because she was bored and I was the primary caregiver.

M78 is a reflection nebula located about 1350 ly away in the constellation of Orion.

We see reflection nebulae because the light from a nearby star is bouncing off the gas and dust of the nebula. #astronomy

Take three minutes to look at pretty birds, explore radar data, and see how we connect the structure of skies to MacArthur's ideas of niche partitioning. 📡🐦☁️🎧

M104 is a spiral galaxy located about 9.5 Mly away in the constellation of Virgo.

M104 is known for its prominent dust lane, visible across the galaxy image. We can see this as the galaxy is nearly edge-on to our view. #astronomy
