Residents of an inshore Bridlington Bay shipwreck attend the BRUV for day 4 of #25DaysOfFishmas. A shoal of pouting investigate the bait cage, while tucked away in a triangular hole top left is a rarely filmed visitor in these waters - a shy conger eel awakes and surveys the melee outside! 🐟🧐🎅🦑

The first image of #3IAtlas from ESA's JUICE mission is in! I reprocessed the image to remove hot pixels (left) and the stars (right) to make the tail easier to see. Credit: ESA/Juice/NavCam Processing: Simeon Schmauß

Yardangs in East Candor Chasma, as seen by NASA's Mars Reconnaissance Orbiter. The area shown is about a kilometer across. (Worth embiggening.)

🌞🛰️Sun-watcher SOHO turns 30! 🎂 "SOHO has overcome nail-biting challenges to become one of the longest-operating space missions of all time" – Prof. @cmundell.esa.int , ESA Director of Science 👉 www.esa.int/Science_Expl... 🔭🧪

it finally rained, so the yard is filled with funny guys again

NASA's Curiosity Rover found evidence of tides in the sediments of an ancient lake. Today's Martian moons aren't big enough to to do that. Mars may once have had a much larger moon, which then shattered (perhaps repeatedly), creating the smaller moons of today. 🧪🔭 agu.confex.com/agu/agu25/me...

Spotted Gars think they’re salmon swimming upstream😂 Most gars do in fact migrate to spawn, typically from rivers & lakes into adjacent floodplains. Some gars, however, swim upstream to spawn. Unlike salmon, gars don’t die after spawning, but often return to the same spawning areas👍 🎥 D.McDonald

I’m here to remind folks that we live next to a star — a huge nuclear fusion factory of plasma and radiation — and proximity gives us an opportunity to study a star! We often take it for granted as “the Sun in the sky” and consider stars just points of light — but we have one right next door too!

The Christmas darter isn't the only darter in the holiday spirit! Other seasonally-appropriate darter species include the candy darter (Etheostoma osburni), lollipop darter (E. neopterum), Halloween darter (Percina crypta), and, of course, the holiday darter (E. brevirostrum) #25DaysofFishmas

On the 1st day of #Fishmas, we present the noble Copper Redhorse (Moxostoma hubbsi), an endangered fish found only in the St Lawrence & Richelieu rivers in southern Quebec. It's known in Quebec as "le chevalier cuivré" ("the copper knight") b/c its large scales are like chain mail. #25DaysofFishmas

The southeastern US is a global hotspot of freshwater fish biodiversity, supporting almost 2/3 of the country’s fish species! The region is also a hotspot of darter diversity - Georgia alone is home to ~45 species including the Christmas darter #25DaysofFishmas

Ok everyone let's get in formation 💃 NSF–DOE Rubin Observatory’s image of the Trifid and Lagoon Nebulae captures several dazzling open star clusters. 🌌💫 These clusters are young, loosely bound families of stars that will eventually drift apart over millions of years. 🔭🧪 🧵

bryologists please keep your eyes out for the legendary American Moss Shrimp, probably about 1 mm long and looking something like this

3/3 Time to update the Gas Giant Portrait I created, now including the new versions of Saturn and Uranus I recently processed. Full size & more info: flic.kr/p/2oUkYSY 🔭🧪 Credit: NASA/ESA/CSA/STScI/AndreaLuck Jupiter is next on the list to be updated :)

What does the fox say?🦊 Today, we’re showing off our favorite pictures of culpeo foxes we’ve spotted around Cerro Pachón, home of NSF–DOE Rubin Observatory. 📸 💡Fun fact: While these little guys look like foxes (and are called foxes), they’re actually more closely related to wolves and jackals!🔭

Travel from the comfort of your own home this #25DaysofFishmas as we explore fishes from all across the US each day in December. Best part? No sleeping on air mattresses in guest rooms! The road trip kicks off with fishes from the southeastern US on Monday Dec. 1!

Go my Bothriolepis... This year's fish pecan pie! Bothriolepis was a peculiar-looking placoderm from the Devonian period or the Paleozoic. It had two long pointed pectoral fins and silly little eyes on top of its head. #fossil #fish #paleontology #bothriolepis

#HappyThanksgiving from WitmerLab! You have your holiday traditions, and we have ours! Yes, we CT scanned our turkey on our best turkey platter. Science has never been so delicious! And like any good dinosaur biologist, I prepared and accessioned the skeleton—OUVC 10789. 🦃🦖

The nearly complete Nancy Grace Roman Space Telescope has made another set of critical strides toward launch. This fall, the outer portion passed two tests—a shake test and an intense sound blast—to ensure its successful launch: go.nasa.gov/4ooRM2L #NASARoman 🔭 🧪

I don't know why this idea is suddenly flaring up online so early, but yeah, this time next year, Voyager 1 will be one light-DAY away – meaning it will take light a whole 24 hours to travel between Earth and the spacecraft. For comparison: Mars is a few light MINUTES from Earth!

Have you ever heard of an allonautilus? The fuzzy sea peach at the top of my oil painting is the extremely rare allonautlius. Its only been documented in the wild a couple of times. *more in comments* #nautilus #allonautilus #marinelife #cephalopods #wildlifeart #oilpainting 🐡 🦑 #deepseamining

☀️ Lessons from the November 2025 solar storm Last week, Earth was hit by a large solar storm. The event provided an opportunity for multiple ESA missions, whether orbiting Earth or far into deep space, to collect radiation data, which is now being analysed. www.esa.int/Space_Safety...

The 54-mile-long Talimena Scenic Drive passes over the Ouachita mountains and winds through the Ouachita national forest in southeast Oklahoma. While beautiful any time of the year, it comes alive in the fall with vibrant foliage. This video showcases some of my favorite views on Nov 6. #Oklahoma

Very excited to share the NASA/ESA/STScI press release of our team's work on Apep! It's a terrific writeup, complete with a brand new beautiful visualisation of the nebula geometry. 1/? ⚛️🔭🧪 science.nasa.gov/missions/web...

This should be interesting 👀☄️ Mark your calendars for 3pm EST Wed.! www.nasa.gov/news-release...

#PPOD: Saturn is seen here through the lens of NASA's Cassini spacecraft during a ring plane crossing in February 2005. The picture reveals the razor-thin ring plane in blue, atmospheric bands in gold, and moons Dione and Enceladus as slight "bumps" in the rings. 🧪 🔭

I will never get tired of watching meteorites blast new craters on the Moon. This likely lunar impact flash appeared today. Like a space firefly. 🧪

For the first time, scientists have documented an unusual defense: Some species of arachnids build giant doppelgängers on their webs, creating a frightening deception that scares off would-be killers. https://scim.ag/487Myn0

my new #sciart for @chistinesd.bsky.social: her research in @newphyt.bsky.social reveals arbuscular mycorrhizae in the stem of the early plant Aglaophyton from 407 million years ago, showing that fungal-plant symbioses are as old as the earliest soils. nph.onlinelibrary.wiley.com/doi/10.1111/...

anyway this artist Charles McKim is really cool and I'd never heard of him, yeah don't bother making any prints or anything though. continue to sell chocolate and socks

WE ARE BACK!! And the Roman telescope is looking *GREAT* as we continue to prep it for launch here at @nasagoddard 🚀✨ Roman is designed to unravel the mysteries of the dark universe - dark matter & dark energy - as well as finding tens of thousands of new planets outside our solar system.
