Can some planetary scientist please teach Avi the most fundamental basics of comets? Like how tails work, and what previous comets look and act like? Because holy moly, this is embarrassing.
New image of interstellar comet 3I/ATLAS by M. Jäger, G. Rhemann & E. Prosperi.
Avi Loeb's: "Is the network of jets associated with pockets of ice on the surface of a natural cometary nucleus or are they coming from a set of jet thrusters used for navigation of a spacecraft? We do not know."

Read this thread. This is what @katmabu.bsky.social was protesting, and why she repeatedly says getting beaten up by ICE outside is nothing compared to the torture and crimes being committed inside Broadview. These thugs must be held to account.
A family friend was telling us about what her husband shared about his experience in Broadview before he was deported back to Mexico. She's been sharing to friends and family because she's just in disbelief & horror what her husband told her. She wasn't able to talk to him until he was in Mexico.

I feel like I say this every year but I really need people to hear it. Halloween is the best American holiday. Just kids outside welcomed into their world, marching around together, showing off their costumes to the elderly, parents meeting parents, neighbors catching up with neighbors.

New incredible detail here: ICE says a match in its facial recognition app Mobile Fortify is a "definitive" determination of a person's status, and that this overrides birth certificates. This is an app ICE is using in the field to scan people

Good. When I worked for the National Park Service I had to learn about the Hatch Act and be sure not to violate it when talking to the public, coworkers, or even sending messages while using a government computer.

This is why we fund scientists to study things like oyster slobber even if you don’t think it sounds important
⚠️ Chinese researchers have invented bone glue that mimics how oysters stick to surfaces underwater.
The adhesive can reportedly repair orthopedic fractures in 2-3 minutes, even in blood-rich environments, and is bioabsorbable.
