40 years ago, the Giotto mission was writing history:  🛰️ ESA's first deep space mission ☄️ first cometary close flyby ⏰ and later on, first reactivation of a spacecraft The success of Giotto inspired our Rosetta mission and together laid the foundation for our Comet Interceptor mission. 🔭 🧪 1/3

possible paleoart reference: I was trying to figure out what that third line was...

🧃 Juice update! 👩‍💻 Science teams are busy analysing the 3I/ATLAS data received from five Juice science instruments ☄️ They're also looking forward to a star occultation by Jupiter’s moon Kallichore on 18 March, which could refine its known position – valuable data for a possible 2031 flyby. 1/2 🔭🧪

🌊 🌿 Scripps Oceanography scientists are here to “kelp” uncover San Diego’s kelp history. Researchers have released an unprecedented record of kelp forests off La Jolla and Point Loma, revealing a steady long-term decline beyond normal boom-and-bust cycles. Dive in. ⤵️ https://bit.ly/40Rvddr

After a night of skywatching a blue glow begins in the east, visible only in the camera at first. Then it rises noticeably into the sky, turns white, then eventually the sky is blue again. The stars are re-veiled, but I know they're still there. The owls stop calling, but they're still there, too.

“bathynomus giganteus” mixed media, by me :) wanted some new room decor so i made it #isopod #mixedmedia

Come on, just look at him. Little weirdo minding his own business in the groundwater and saturated interstitial soil spaces. Then during periods of high water tables the earth vomits him up through a seep, whence a most unlikely creature plucks him from the mucky leaves.

From NASA Our Eye on Mars 🔴 As it marks 20 years at the Red Planet, here are five ways NASA's Mars Reconnaissance Orbiter (MRO) is mapping the future of exploration. 🛰 ➠ 👩‍🚀 🧵

Episode 43 of the Kilauea eruption is a BEAST. They just zoomed out and uhhh this may be on its way to setting a record for tallest lava fountains. What on Earth. 😍🌋 Cam 2 live: www.youtube.com/watch?v=fiyt...

🚨 UPDATE: fireball over Europe – 8 March 2026 At 18:55 CET on Sunday, 8 March, a very bright fireball streaked across the skies of Belgium, France, Germany, Luxembourg, and the Netherlands, glowing for around six seconds before fragmenting. 🧪🔭 🎥 Allsky7

Thanks so much for hosting, Élle! Congrats on 18K!! 🎉 I'm Tisha, an artist north of Boston using oil paints to tell stories about light and atmosphere. Original paintings are available on my website: tishamark.com/shop

Yesterday's storm chase along the TX/OK border didn't play out as I had hoped, but that's not too surprising for early season setups. Still, there's almost always at least a bit of a consolation prize. This struggling storm painted by the setting Sun was yesterday's. #Photography

🆕 Cast your mind back to May 2024... remember how a massive solar storm triggered northern lights across Europe? We can now reveal how this same solar storm affected Mars, thanks to clever teamwork from our two Mars orbiters. Find out more 👉 www.esa.int/Science_Expl... 🔭 🧪 ☀️

Astronomers are losing their minds over #NASAWebb’s latest images of the very brainy-looking nebula PMR 1. Its distinctive form is the result of a dying star expelling its outer layers: https://news.stsci.edu/4tVQccE 🔭 🧪

😲 *stunning* new image from #jwst The "Exposed Cranium" nebula showcases what can happen as a star nears the end of its life. The outer shell (or skull 😏) is mostly hydrogen gas, & the brain is a mix of different gases that have been expelled from the star. More: science.nasa.gov/missions/web...

One of the annual #southpole traditions at the start of winter is watching John Carpenter's #thething in the gym. A fitting start to over 8 months of isolation for the 40 winterovers after becoming officially stranded at a remote Antarctic base! #Antarctica

From high-impact weather events to stratus clouds dancing over the open ocean, this year was filled with impressive satellite imagery. We look back on the most compelling satellite views of 2025. 1) Mesovortices slosh within Hurricane Melissa’s ferocious eye (October 8).

I came across a great photo of a Mooneye, Hiodon tergisus, from the St. Croix watershed in Minnesota. Photo by Drew Geving. Minnesota is working to implement new protections for "native rough fishes" such as Mooneye and Bowfin. It's the first US state to do so, finally. 🧪🌍🐟 #TeamFish

A star has died! For the first time, astronomers have used #NASAWebb to identify which specific star exploded as a supernova. The star—located in galaxy NGC 1637—was a red supergiant surrounded by so much dust that it was invisible to Hubble: https://news.stsci.edu/4alt51V

From NASA One image from the upcoming Roman telescope would need an entire wall of 4K TVs to display. The sharpest large-scale cosmic map ever will reveal our universe, hundreds of millions of galaxies, and clues to dark matter. The universe is about to get a lot clearer: go.nasa.gov/4qRJDVM

The first photo I captured of the 9-23-23 Ada, OK supercell (after a few test shots). Yes, all three lightning strikes were captured in a single image! From my distant vantage point, this intricately-structured supercell gracefully danced under a sky full of stars with unmatched beauty. #Photography

STScI is opening its doors for a celebration of creativity at the intersection of art, science, and community on May 6 at 6 p.m.! The evening will feature an art exhibit of works by local artists inspired by space and astronomy. More information: https://www.facebook.com/share/17HoRP1ZxM/

Happy 5th Landing-iversary to the Perseverance Mars Rover! I made this illustration to celebrate the landing 5 years ago and it’s still an all-time personal favorite. #sciart #spaceart #marsrover #illustration

Five years ago today! We imaged Perseverance on its descent to Mars, under fairly challenging conditions but we did it because we have a kickass team. www.uahirise.org/ESP_068281_9...

Both Mars rovers are still roving. Here’s Perseverance's latest view (L) and Curiosity's (R) — taken yesterday. Ride along at science.nasa.gov/mars/

it's incredible how fast the last 5 years have flown by. Happy anniversary to #Perseverance landing on Mars! 🎂🥳 If you want to relive this incredible moment, look no further than this remastered video of the #EDL by @stim3on.bsky.social @theseaning.bsky.social 🔭🐡🧪🎨 www.youtube.com/watch?v=HHhy...

Jupiter bonanza scheduled for JWST starting this Friday 🔭 - woo hoo! The teams are calling on amateur astronomers to assist with context imaging of the Solar System's largest planet.

Check out our new #OpenAccess paper in @commsbio.nature.com redescribing bewhiskered Jurassic shark Bavariscyllium, led by Sebastian Stumpf. Although relationships hard to pin down, its catshark-esque form shows sharks explored varied body shapes from the start. 🦈〰️ www.nature.com/articles/s42...

For the record @drfishsg.bsky.social and I are BOTH big fans of Bowfin! Photo from fieldwork collab 11 years (!!!) ago on restored wetlands in Green Bay, Wisconsin.
