Yay! Dr. Tanya Atwater finally getting public credit for her (very big) role in the plate tectonics revolution.
The discovery that the continents are in continuous motion is fairly recent—dating back only to the late 1960s — and one woman was responsible for decoding what it meant for California and much of the West Coast.

Stunning footage from earlier today, when the new Kilauea eruption covered the USGS Webcam 3, which is situated in the Halemaʻumaʻu crater near the southern rim of the much larger Kilauea caldera.
This *isn't* what the people of Pompeii saw.

The distance was "only" 0.2 AU or 30 Mio km, far closer than the comet ever got to Earth. 🔭 #3IAtlas

No Avi, that Perseverance Navcam picture you posted isn't showing 3I/Atlas, it's just Phobos, the brighter one of Mars' moons.
If you were even half the expert you think you are, this possibility should have been quite obvious and worth mentioning.
