What Seismology Tells Us About the Captive Elephants at Six Flags
A groundbreaking seismic study reveals that Joyce, an elephant held at Six Flags Wild Safari, lives amid near-constant human-made vibrations, an unnatural and potentially harmful sensory world.

We took a brief break from our planetary research to help figure out what's bothering Joyce! #savejoyce @worldanimalprotection.us www.worldanimalprotection.us/latest/blogs...

I'll bite. No matter how many places I live, you can't take the Michigander out of me. Also, the only reason why Phoenix is number 3 is due to the high amount of MI transplants trading the snowy weather for 110F heat.

⏳ The countdown is over.
#BepiColombo's Mercury Transfer Module should have now separated from the spacecraft, a key step in the mission's journey towards orbiting #Mercury. 🛰️↔️🚀
Now expecting acquisition of signal confirming separation no earlier than 15:53 CEST.

An incredibly well-timed Landsat 9 pass captured the effects of yesterday’s catastrophic glacier collapse near the Nepal–Tibet border. The event was so massive that it was detected by seismometers around the world.

We are heartbroken 💔 to see the images and videos coming out of Nepal this morning. Initial footage suggests this was a hugely destructive event originating in glacierized terrain. Our thoughts are with all affected communities and emergency responders. #cryohazards #rasuwa #glaciers #hazards

I can't wait!
I'm on the science team of the Lunar Environment Monitoring Station (LEMS), a compact, autonomous seismic station designed to be placed on the lunar surface on a future Artemis mission.
This is an engineering mock-up of LEMS at GSFC yesterday.
Its twin is going to the Moon.

New images just dropped from NASA's Lunar Reconnaissance Orbiter, showing the crater formed by a SpaceX Falcon 9 upper stage when it hit the Moon on 5 August 2026.
The new crater is 18 m across and 3 m deep.
