Most fieldwork posts show smiling people, beautiful landscapes, and/or interesting things. For a view of the other side, I give you fieldwork in Nepal with endless rain (thanks cyclone Montha), mud everywhere, and leeches. One of my more difficult trips in recent years...

It’s such a relief to see her happy and comfortable again. Y’all I am so codependent with this stupid cat

Goddard spacecraft engineer: "I think it just kind of speaks to the atmosphere of the agency and the nation, where people are like, 'Well, laws don't matter for the people at the top anymore.'"

This is the surface of Saturn's giant icy moon Titan, photographed by the Huygens probe on 14 January 2005. It is the farthest place from Earth where we have so far landed.

Whenever I get Chinese food, I always make sure to get a second fortune cookie for my dog. I opened his up and read his to him: "You are adored by many." So true, he is. I then open mine and...there was no fortune. The cookie was empty. Too real.

I've been a professor for a decade and my parents still ask me "how was school?" whenever we talk lmao

Ganymede. The biggest moon in the Solar System. Bigger than Mercury, and with a rocky interior under NINE HUNDRED KILOMETRES of ice and water.

Big shoutout to @geosociety.bsky.social for upping the ribbons game at the GSA meeting with an impressive variety of geonerd-themed ribbons available for attaching to our badges. 🧪🪨⚒️🤣

Layoff notices at JPL are going out today. About 11% of the Lab, or 550 people, are being let go. I'm thinking of my friends and colleagues there, some of whom will still be employed after today and some of whom won't. I'm sorry you're having to deal with this.

Before laser pointers we had to just point at the wall with a stick. Photo from my collection, no date/info.

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

It's been months since I've been out in the backyard. Here is a little bit of Saturn from tonight in Whittier, CA. #astronomy #astrophotography #saturn #LAAS

🌊With the Fall semester upon us, it's time to start thinking about recruiting/applying to grad school for 2026. If you are a marine scientist looking for a graduate student, I've created a form where you can add your name and other info: docs.google.com/forms/d/e/1F... Please share widely! (1/2)

Are you someone who is interested in astronomy graduate school? This is a list of many/most departments and their expectations for admissions this year. Please feel free to spread it far and wide. If you are doing admissions and you'd like to update your entry, reach out as per the form!

A few hours ago, Comet 3I/ATLAS passed about 28 million km from Mars. This was the best opportunity we'll have to image the interstellar visitor from spacecraft. When those data are available, I'll share them!

Our galaxy is full of rogue planets, worlds that live in darkness without a parent star. And now we've caught one as it forms, scooping up gas at a rate of 6 billion tons a second. 🧪🔭 www.eso.org/public/news/...

Almost exactly 30 years ago, the first extrasolar planet was identified orbiting a main-sequence star. Now, not only can we directly image planets orbiting other stars, but we can see planets *being born* Imagine what the next 30 years will bring.

Spectacular concentric zoning and twinning of large titanaugite in essexite (nepheline monzogabbro) from Lennoxtown, Scotland. Plagioclase inclusions within the phenocryst align with zoning just as proximal groundmass plagioclase align with its edge. #ThinSectionThursday 🧪⚒️

CNSA has released an image of Tianwen-2 in deep space using a robotic arm, giving us a proper look at the spacecraft and return capsule for delivering samples from near Earth asteroid 469219 Kamoʻoalewa. Tianwen-2 has been in space for 125 days, is 45 million km from Kamoʻoalewa.

Here is the trilobite Angelina sedgwickii from the Lower Ordovician (Tremadocian) Dol-cyn-afon Formation from Wales, U.K. This trilobite is slightly distorted due to tectonic forces. It is a great teaching piece to discuss structural geology.

Keep sciencing. We are living through a time when looking at a rock and wondering how old it is qualifies as an act of resistance.

Asteroid Donaldjohanson just got some new names for its various surface features. The names were proposed by the NASA Lucy mission team to the IAU based on various paleoanthropological sites and discoveries. science.nasa.gov/solar-system... #PlanetSci

The final target for the Hayabusa2 mission is a tiny asteroid. We knew it was small, it turns out is much smaller than expected. Not much bigger than the spacecraft What's killing me is the size comparison with Ryugu, the first target of Hayabusa2! So wee! 🔭🧪 www.iflscience.com/hayabusa2s-t...

One of the samples that I was working on today, a hefty slab of "Duke Stone" metaignimbrite from the Piedmont of North Carolina. This is the rock that was used to build the Gothic architecture of Duke University. Made in a pre-Appalachian volcanic eruption, it got squeezed as Pangaea was assembled.⚒️
