To search for Earth-like planets our Plato mission will use 26 cameras in a design inspired by the compound eyes of insects. The mission will spot any slight dimming or brightening of a star when a planet passes in front of it. Learn more about Plato's 'eye' 👉 www.esa.int/Science_Expl... 🔭

The latest @science.esa.int newsletter includes information on a new opportunity: a call to be part of the ESA advisory structure.

Meet the 2025 Research Fellows in space science! They were selected to pursue their own independent research in space science at one of our establishments. Find out who they are and what kind of research they do here 👉 www.esa.int/ESA_Multimed... Congratulations to all! 🧪☄️

And that’s a wrap on #EuclidConsortiumMeeting2025! Hundreds of #HumansOfEuclid are heading home after catching up in #Leiden 🇳🇱 🌌 Latest data was shown 🚀 Incredible new results shared 😃 Friends were made Thanks to all the organisers and sponsors for such a wonderful week! #Euclid #Space

Goodbye Gaia spacecraft and no worries: all your data are in excellent hands and the next Gaia data releases will keep the scientific community busy for many many years with new exciting discoveries.

Agree, really cool app!

More than a thousand citizen scientists across the world took part through Space Warps, the dedicated strong lens search project hosted on the @galaxyzoo.org platform. (2/4)

Enjoyed the latest #ESAEuclid images? Why not exploring them in depth? Go to sky esa urlzs.com/F6PeAo and choose between the Science or the Explorer mode to access them. 🔭🧪 #astrosci

If you want to spend some quality time with #Euclid data, you can use "ESA Sky", which allows everyone to browse public data, pan, zoom, and look around. All in full colour galore, and full resolution. #astronomy #space @esa.int 1/2

Scientists hail ‘avalanche of discoveries’ from Euclid space telescope

So many things to be excited about with today’s #ESAEuclid data splash, but this👇is the result I’m most in awe of: “mass curves spacetime” in action, revealed in exquisite detail for absolutely oodles of galaxies, all thanks to citizen scientists❤️ 🔭🧪

Thank you @ec-euclid.bsky.social consortium scientists for your hard work preparing these data & congratulations to all teams on the release, phenomena science productivity & innovative inclusion of nearly 10,000 citizen science volunteers in this exciting milestone @science.esa.int @esa.int

It's #Euclid data release day! @esa.int and the Euclid Consortium are making 63 deg² of Wide Survey data available to the world. Imaging and spectroscopy data, catalogues and masks for 20+ million galaxies, quasars, stars and substellar objects. #astronomy #science #space 1/4

#AI is used in nearly half of the papers published today by @ec-euclid.bsky.social for Q1.

#Euclid’s release today unlocks a treasure trove of information for scientists to dive into. “With this, ESA is delivering on its commitment to enable scientific progress for generations to come,” declared cmundell.bsky.social, ESA Director of Science. 9/ 🔭🧪 #astrosci

The mysteries of the dark universe are set to be revealed, thanks to cutting-edge UK science. 🌌🔭 New data from @esa.int's #Euclid mission includes details of galaxies experiencing strong gravitational lensing, helping scientists identify where dark matter is located.🔎 👉 gov.uk/government/n...

The mysteries of the dark universe are set to be revealed, thanks to cutting-edge UK science involving Fellows from the RAS.🌌 New data from #ESAEuclid includes details of galaxies experiencing strong gravitational lensing, so scientists can identify where dark matter is located. 🔎 ⤵️

ESA Sky is amazing 🤩

Time for a close up! 📸 Here we zoom into #ESAEuclid ‘s Deep Field North and bump into the beautiful Cat’s Eye Nebula! 😻 (1/3)

A nice write-up by @theguardian.com on the @ec-euclid.bsky.social data release, including some quotes on the avalanche of gravitational lenses by @stephenserjeant.bsky.social 🧪🔭 www.theguardian.com/science/2025...

The first Euclid survey data release is out 🎉 With data on the ESA Euclid archive and Datalabs platforms, a new video on YouTube, images on ESAsky in very high resolution, 34 scientific papers written by Euclid Consortium members. An enormous effort, from so many people!

I presented to ESA Council the 1st data from @esa.int's Euclid mission. This dataset includes 26 million galaxies, including a catalogue of more than 380 000 galaxies and the first catalogue of 500 galaxy-galaxy strong lenses, created using AI algorithms trained by the effort of 10k volunteers. 🅰️🧵👇

Ca y est ! Les premières données scientifiques de la mission @euclid-france.bsky.social sont enfin publiées. Elles proviennent d'une toute petite portion de la surface totale prévue. Ci-dessous, en jaune et numérotées, les 3 parties sur lesquelles portent cette 1ère release. #thread à dérouler

Our March issue is here! Learn about gravitational lenses, the changing length of the day, and ballistic cucumber seeds. 📸: Image from ESA/Euclid/Euclid Consortium/NASA, processing by J.-C. Cuillandre, G. Anselmi, T. Li. #PhysicsToday ⚛️🔭 pubs.aip.org/physicstoday...

Coming up

Astro job alert! 🚨🔭 @science.esa.int is hiring a Project Scientist for NASA's Roman mission, to join our ESA office here at @spacetelescope.bsky.social in Baltimore! Check out the job ad and please share with anyone who might be interested! jobs.esa.int/job/Baltimor...

Euclid Einstein ring is astronomy picture of the day 🤩 @esascience.esa.int

At the Space Science Workshop, the annual scientific retreat of the ESA space science faculty. Great dynamic format this year, 5-minute talks and posters, lots of occasions to talk, two “unconferences” on machine learning and visual trust. The stunning Einstein ring. Horses also had a visible role.

European Space Agency: Euclid Discovers a Stunning Einstein Ring www.esa.int/Science_Expl...

Euclid telescope captures Einstein ring revealing warping of space

🌌Einstein Ring Discovered by @esa.int's Euclid in galaxy NGC 6505 "just" 590 million light-years from Earth, which relatively speaking, is quite close! The newly discovered ring is made up of light from a previously unobserved galaxy 4.42 billion light-years away.

Bullseye! Remarkable discovery of an Einstein Ring in the heart of nearby galaxy NGC6506, imaged by @esa.int @esascience.esa.int #Euclid mission. Crystal clear vision of #Euclid & sharp eyes of Euclid scientists spotted this rare occurrence that shows the promise of Euclid for precision cosmology!

www.science.org/content/arti... 🔭🧪 @science.org

This is the first time that the ring of light surrounding the centre of NGC 6505 is detected, thanks to Euclid’s high-resolution instruments. 🔭🧪 #cosmology

It's time for a Euclid scientific highlight and stunning discovery! An Einstein ring, a rare phenomenon that demonstrates how Euclid can see new things, even in well-known galaxies. You never forget the first Einstein ring, the first of many to come!

Euclid showed us a spectacularly panoramic and detailed view of the Horsehead Nebula. No other telescope can create such a sharp and wide view as Euclid can with just one observation. 4/9
