Early reviews are starting to filter in for NIGHTFARING, and I am so grateful to Jamie Carter at Forbes for including it on his list of the best books for stargazers. What a lovely review from a fellow night sky lover. 🌌🙏 www.forbes.com/sites/jamiec...

NGC 6058 (blue object, centre) is a planetary nebula located about 11 kly away in the constellation of Hercules.
Planetary nebulae are the penultimate stage of evolution of stars like our Sun. The star has blown off its outer layers and the remnants of the core cause that gas to glow. #astronomy

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:
www.swpc.noaa.gov/communities/...
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

🦇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.
