The @accuweather.com acct hasn't posted here on Bluesky in two months but they did put this map together on their other socials, showing verified shots of the 11/11 aurora in all 50 states. Solar Cycle 25 has defied expectations and has been giving us a show for a year and a half.

If you've ever wanted an author to explain their entire paper, here is me explaining this entire paper. JWST spectroscopy of asteroid Polana and why I think the Polana family is the origin of NEA Bennu. #planetaryscience 🔭
✨ Anicia Arredondo chats about near-Earth asteroid (142) Polana and where this exciting research may take us next.

New #planetaryscience paper! #JWST spectra of (142) Polana, the parent body of the new Polana asteroid family. We compare Polana to Bennu and Ryugu to test hypotheses that both NEAs came from the new Polana family.

July 29, 2025 marks 67 years to the day since the founding of NASA. NASA Spinoff—a section of the US space agency’s technology transfer program—compiles just about every commercial technology that has originated in US space research, from freeze-dried food to wireless vacuum cleaners.

New paper! I observed the three largest members of the Eurybates family (the parent body is a target of the Lucy mission) with NIR spectroscopy to see if there were changes in the spectra as the asteroids rotated. 🔭🧪

In addition to these never-before-seen cosmic neighbors, Rubin detected another ~1800 previously-known asteroids, bringing the total detections to just under 4000 in just 10.5 hours!🔭🧪
In other words, over half of Rubin's first detections are new discoveries☄️

I really like this video showing some of the 2104 asteroids found in 10 hours of data - really gives a sense of how Rubin's view of the changing sky will be different. www.youtube.com/watch?v=JrmI...

A look at my camera roll from 1 year ago on eclipse day. We were supposed to see 4.5 minutes of totality, but the clouds had other ideas. Luckily, they thinned out long enough for me to get one photo! 🌞 🌝 🤠

☄️JWST managed to image asteroid 2024 YR4 this month, and its infrared scopes got a really good estimate of its size.
Turns out it was 60m (+/-7)—sufficient to wreck a large city. Good thing it wasn’t heading to Earth after all…
