🌎 NASA's Artemis II mission has splashed down and all four astronauts are reported safe, bringing an end to a stunning flight around the moon. www.scientificamerican.com/article/nasa...

Reports this week claimed the CIA used a tool called Ghost Murmur—allegedly powered by “long‑range quantum magnetometry”—to detect a downed Air Force officer’s heartbeat in the mountains of Iran. It's a great story, but there's one problem: The tech is almost certainly impossible.

Astronaut Bill Anders took the iconic 1968 photo "Earthrise." “It's really too bad, we're shooting missiles and rockets and whatnot at each other…" Anders later said. "It's the only home in the universe for us humans." Artemis II just recreated the photo: www.scientificamerican.com/article/in-a...

The Artemis II Orion spacecraft is at the peak of its trip around the moon—the first time humans have passed nearby in more than 50 years. As they make the flyby, the four astronauts will travel farther in space than any human before them. www.scientificamerican.com/article/nasa...

Artemis II has successfully launched and the first crewed moon mission of the 21st century is on its way! www.scientificamerican.com/article/nasa...

The new issue of @sciam.bsky.social describes a cosmic conundrum that's keeping astronomers up at night: We assume galaxies are held together by dark matter because without it all the stars would simply fly apart. So what's keeping together galaxies that have no dark matter at all?

A mixture of AI and algorithms uncovered a hidden structure spanning 2,000 years of equations for pi

The venerable Hubble observatory is going strong despite its decades in space and the advent of next-generation successors

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. www.scientificamerican.com/article/the-...

“These tropical lizards were experiencing conditions that they’ve never experienced in their entire evolutionary history before, tens of millions of years”

Look how excited I am to get a sneak peek of the Public Science Common at @museumofscience.bsky.social! It's super secret inside so no pictures, but this is going to be an incredible space for live events and science education. I can't wait for collaborations with @sciam.bsky.socia... stay tuned!

Now on @sciam.bsky.social: Did astronomers photograph UFOs orbiting Earth in the 1950s, years before human activity there? New peer-reviewed studies suggest the answer is “yes,” but skeptics say these conclusions are premature. By @astrojonny.bsky.social. www.scientificamerican.com/article/did-...

How can reconstructing long-lost smells of ancient artifacts help us connect with the past?

This is only the second time we’ve had more than two Category 5 storms in a single Atlantic hurricane season

As cat 5 hurricane Melissa bears down on Jamaica, it is poised to be the worst storm to ever hit the Caribbean island, surpassing Hurricane Gilbert in 1988, which killed 49 people, destroyed 100,000 homes and did $700 million in damage www.scientificamerican.com/article/why-...
