THIS IS WHAT IT LOOKS LIKE WHEN YOU SLAM A ROCKET INTO 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.

A new video emerged which seems to show a surface rupture in Yatsushiro, Japan following the M6.8 earthquake in July! Exact location of the video would be 32°30'04.0"N 130°38'29.9"E. Absolutely wild. Only the second ever video of a surface rupture forming after the 2025 Myanmar video! ⚒️🧪 #geology
Sitting on top of a giant landslide in Svalbard at 78N is a pretty fucking place to see the eclipse
Happy World Elephant Day!
UMD Geology@umdgeology.bsky.social · 2w agoUMD Geologists Measuring Ground Vibration Near an Elephant Enclosure GEPS faculty used seismic monitoring to address a non-traditional challenge (i.e., not earthquakes): investigating ground vibrations around an amusement and safari park in New Jersey #worldelephantday go.umd.edu/2d8t
IT WORKED! Thousands of you wrote your senators, and the Senate passed a funding bill pausing the OMB rule that would hand political appointees control over science grants. But it's not over: the House's bill doesn't include the pause. Tell your Rep to back the Senate's language: planet.ly/cPbNu
Friends in southern Arizona have taught me not to spend much time outside or walk the dog when dust from these storms reaches us in the north. The number of people and dogs I know with Valley Fever is troubling.

I will then continue running at 5 am with these temps and humidity levels.
Capital Weather@capitalweather.com · 2w agoIf you liked yesterday, good news. If not... 🫣 More heat. More humidity. More storm chances late in the day. Pretty much the same into the weekend. Hotter to start next week? Full forecast at CapitalWeather.com (Photo by Mary Clive)
I feel like I cheated on WMATA tonight with Lyft. I was totally planning on taking the metro back home but walking out of the airport at 8pm after a 9 hour flight from Europe and seeing that Lyft would shave an hour off my commute home..... I knew what the choice would be tonight.
#BepiColombo is approaching Mercury 🛰️🌑☀️ And we’re here for it! 🙌 On 3 September, the @esa.int / #JAXA mission will carry out its first arrival manoeuvre, kicking off the Mercury Arrival Phase. Want to watch live on 3 Sept? ️️Stay tuned here and on @science.esa.int for more details on 27 August 🗓️
Part of a SpaceX rocket weighing 8,800 pounds is about to crash into the moon at 5,400 mph, releasing an amount of energy equivalent to about 3 tons of TNT. WOW! And, the event might be visible from the East Coast by telescope early Wednesday. More details: www.capitalweather.com/part-of-a-sp...
We have acquired a new friend during our trip to Berlin.
@macsquirelera.bsky.social I wasn't able to reply but thought I'd share when I visited Dachau and this lady kept taking selfies with her selfie-stick among the flowers around the area. Yes, please, take that beautiful photo of yourself next to the "showers".

I think the word here is "cathartic." Eruptions heads into hiatus ... and my musings on where we are in science communication, education, research and life: eruptions.site/2026/07/23/t...

So, as most of you know, it has been a rough few years in the realm of science, education and journalism. I won’t get into the big picture issues individually, but they are the backdrop for t…

Over the past weeks, I've started listening to songs from my youth. Today was Marilyn Manson, and I forgot how good the Mechanical Animals album is.
Crater Fact Friday ☄️DID YOU KNOW☄️ Layered ejecta craters are hypothesized to form in the presence of subsurface ice, where volatiles are fluidized upon impact. This means these craters can be used as a way to identify subsurface volatiles and resources on other planets!
According to USGS PAGER, 1.4 million people may have experienced strong or very strong shaking, and an additional 17 million people may have experienced light to moderate shaking. earthquake.usgs.gov/earthquakes/...
Dr. Wendy Bohon@drwendyrocks.bsky.social · last mo.Strong or very strong shaking was likely experienced by communities along the coast. Loose soils in these areas may have amplified shaking.
Why did no one warn me the amount of administrative work I'd need to deal with as a scientist?
Update: Photo with rock has occurred! Now to wait a few weeks for the photos.
Jackie Clark@geojackjack.bsky.social · last mo.Now to decide on the rock! I have too many choices! Maybe a large shatter cone from the Sante Fe Impact structure? Perlite (because I have a giant sample)? Too bad I don't have a big piece of copper from the UP (gotta show off those MI roots).
You have time until 11:59 PM eastern to add your comments against this!
The Planetary Society@planetarysociety.bsky.social · last mo.The OMB rule that lets political appointees override scientific peer review on federal grants will be decided after today. This authority won't disappear when the administration changes, it's for every administration going forward, no matter who's in office. 🗣️⬇️: www.planetary.org/advocacy-act...
