NEW: Does Planet 9 exist? No telescope has been capable of finding it—but in 2025, the Rubin Observatory will come online, and with its remarkable eye, it will find out, once and for all, if the elusive world is truly there. My cover story for @sciam:

RT @AsteroidWatch: 📣Discovery alert! One of NASA's planetary defense telescopes first observed an interstellar comet passing through our so….

RT @esaoperations: ESA's astronomers are actively tracking 3I/ATLAS, which is now the third confirmed interstellar comet to pass through ou….

RT @tony873004: 3rd interstellar object discovered? Maybe. There's a lot of buzz right now in the Astro community. More observations should….

The object’s position in the sky, combined with its *very* eccentric (oval-shaped) orbit, makes it look very much like a comet that’s plunged into our solar system from the depths of shadowed space. Could this be interstellar object number three?

Hey, remember ‘Oumuamua and 2I/Borisov? They were the first two interstellar objects ever discovered—sojourners from another star. Well, it’s not yet confirmed, but we may have just found our third interstellar object! Say hello to A11pl3Z.

RT @VRubinObs: Think you can spot a comet? ☄️. Try your eye with the *very first* citizen science project on @the_zooniverse that uses data….

RT @Bobrien2705: MY DOCTOR! #DoctorWho

RT @mjuric: Just submitted the next set of @VRubinObs asteroid data to the MPC. 93 new objects, 2229 observations. Small batch from Nov/D….

NEW: The Rubin Observatory is going to see everything that glimmers in the night sky. It just opened its eyes for the very first time, and saw wonders: bridges of light connecting galaxies, and thousands of asteroids once hidden from view. Me @techreview

YESSSSSSS COME ON LET’S SMASH UP THE MOON.

NEW: You’ve probably seen a few scary headlines (and histrionic stories) about asteroids hiding near Venus that might crash into Earth. So should we be concerned about a fleet of stealthy asteroids killing us all?. (Nah. But we should try to find them!). Me @NatGeo 👇

RT @SquigglyVolcano: NEW: Astronomers have long predicted that the Andromeda Galaxy will one day crash into the Milky Way. Well, good news,….

RT @marinakoren: I wrote about Trump's surprise withdrawal of Jared Isaacman's nomination to lead NASA, and the future of the agency under….

NEW: Astronomers have long predicted that the Andromeda Galaxy will one day crash into the Milky Way. Well, good news, future time travellers: scientists now think that the pull of a small, nearby galaxy might just save our galactic bacon. Me @NatGeo

RT @JCDAmos: This is just crazy.

This sort of outburst is both spectacular and very dangerous (smaller pyroclastic density currents, created by discrete explosions, are still highly lethal). Etna has been erupting near-continuously for some time now, but it’s mostly been lava effusions.

Per the INGV (Italian volcanologists): “Over the past few hours, the activity flagged in the previous statement issued at 4.14am (3.14am BST) has carried on with strombolian explosions of growing intensity that, at the moment, are of strong intensity and nearly continuous.”.
