Notorious asteroid 2024 YR4 won't crash into the moon after all Earthlings aren't the only ones safe from a city-wrecking-size asteroid. Future lunar inhabitants won't have to worry about a strike in 2032 either

NEW: Sad news for those wanting the Moon to be hit by a sizeable asteroid: it ain’t happening, at least not in 2032.

But at least we now that JWST is a surprisingly good asset for tracking dangerous space rocks! :)

The Schrödinger equation is getting a glow-up for its 100th birthday A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking what happens when the observer is part of that world

Now on @sciam.bsky.social: The Schrödinger equation just turned 100, but that doesn’t mean quantum physicists have solved all its mysteries. Chief among them: What, exactly, does it mean to incorporate observers into the gnarly math? By Joseph Howlett.

Sick Astronaut on ISS Forces Early Command Transfer from NASA Crew Member to Russian Cosmonaut NASA astronaut and ISS leader Mike Fincke transferred station command to a Russian cosmonaut ahead of an unprecedented medical evacuation

NASA astronaut and ISS leader Mike Fincke transferred station command to a Russian cosmonaut ahead of an unprecedented medical evacuation

In Unprecedented Move, NASA to Rush Astronauts Home after Medical Incident on ISS NASA on Thursday announced it would take the unprecedented step of bringing four crewmembers back to Earth from the space station before their official mission end

This is a first for NASA--hope the astronaut is ok!

Lazuli, a Billionaire-Funded Private Space Telescope, Signals a New Strategy for Astronomy Bigger than Hubble and launching as soon as 2029, the Lazuli Space Observatory would be the first-ever full-scale private space telescope

The first full-fledged private space telescope could launch as early as 2029--here's a thoughtful look at what that might say about and mean for astronomical science: www.scientificamerican.com/article/schm... 🧪 🔭

Humans Made Poisoned Arrowheads Thousands of Years Earlier Than Previously Thought The use of poison on arrows marked a revolution in human hunting technology—new evidence suggests it happened tens of thousands of years earlier than previously known

This is such a cool finding--the oldest direct evidence of poisoned arrows. Poisoned hunting weapons were a game-changing innovation for our ancestors. Absolutely incredible that researchers found traces of plant toxins on these tiny arrowheads from 60,000 ago 🤯🏹 🧪

NASA’s Nancy Grace Roman Space Telescope Completed - NASA Two technicians look up at NASA’s Nancy Grace Roman Space Telescope after its inner and outer segments were connected at the agency’s Goddard Space Flight

Holy moly: The Nancy Grace Roman Space Telescope construction is completed! That's fantastic news — much needed right now — and I am very much looking forward to when this beast launches. It has 100X the field of view of Hubble.
