OK, look, this is super-niche and I know it, but the set of asteroids that resulted from an ancient impact into Vesta are commonly called "Vestoids" in the community when they should be called "Vestiges" and I've been saying that for decades, so that's my answer thanks for reading.

Two weeks ago northern Chile was affected by severe weather. It caused damage to several cities and brought snow to our observatories, leaving stunning imagery like this drone video of our Extremely Large Telescope.

If you’re in the US, expect maps on your phone to start showing you “Lake America” soon, now that the US Geological Survey has updated the GNIS.
