Canadian scientists from several institutes contribute to the #ESAEuclid mission 👉 www.asc-csa.gc.ca/eng/satellit... Mike Walmsley from @uoft.bsky.social, for example, led the results on galaxy morphology & strong lensing from the first batch of Euclid survey data. 2/

Happy birthday also from us! #Science #Space #Astronomy #Research

Did you know that the world's 16th largest tree is a Giant Sequoia called Euclid? famousredwoods.com/euclid/

The new #esa science newsletter is out: ▶️ https://www.cosmos.esa.int/web/scinews * Euclid first quick data release * F/M and mini-F mission calls are now out with a deadline on May 21 * Cheops AO 6 calls & XRISM AO2 calls for guest observer proposals * Gaia retires, but mission continues * […]

If you're interested in the lastest #EuclidESAMission data release (Q1) and want to get your bearings before diving into the data, you can go to this page, put together by my colleague @knudjahnke.bsky.social www.euclid-ec.org/science/q1/

So long Gaia. Your data is invaluable for ensuring @ec-euclid.bsky.social data all sky photometric calibration. Looking forward to DR4 next year !

Loving the Euclid @ec-euclid.bsky.social galaxy explorer tool by Mike Walmsley. Thanks to the @galaxyzoo.org volunteers for all this work! euclid.streamlit.app 🔭🧪

#ICYMI, #ESAEuclid dropped its first batch of survey data, including a preview of its very own deep fields! 🤩 This video walks you through some of the hidden treasures the #DarkUniverse detective 🕵️ has uncovered. And this is still just the beginning. www.youtube.com/watch?v=rXCB... 🔭 🧪

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

Can't get enough of @ec-euclid.bsky.social? Here are three "key science areas" the consortium identified from the results today and wanted to talk more about: - Active Galactic Nuclei - Galaxy Morphology - Strong Lensing youtu.be/YGqaxDH00Yw

Et voici le communiqué de presse de @cnrs-insu.bsky.social sur Euclid www.insu.cnrs.fr/fr/cnrsinfo/...

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

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

For an explainer on #Euclid's background and what's in the Q1 data release, here's a conversation between Shaun Hotchkiss (@justshaun.bsky.social), Guada Canas-Herrera (gcanasherrera.com) from @esa.int, and our Herve Aussel (@herveaussel.bsky.social). www.youtube.com/watch?v=DVlK... #space 🔭

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

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. 🅰️🧵👇

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...

This looks like it is absolutely not real. But it is. A tiny tiny patch of sky (FoV: 7.1' x 3.6') - so about the size of a grain of rice at arm's length, and ALL of these galaxies in it. And then more beyond that. 🤯 @elsa-euclid.bsky.social @ec-euclid.bsky.social 🔭🧪

Look at ALL the galaxies in the new @ec-euclid.bsky.social images! It's walls of galaxies, and behind them, even more walls of galaxies. It just keeps going on and on. You can find more info on the @science.esa.int page here: www.esa.int/Science_Expl... It's incomprehensible! 🔭🧪

Lights, camera, action! The world's largest digital camera has been installed at NSF–DOE Rubin Observatory! 🤩 The LSST Camera was the final major component of the observatory. With it in place, Rubin officially enters its final phase of testing!🔭 🔗: rubinobservatory.org/news/lsst-camera-installed

I know you are excited about your JWST results (or sad, sorry), but let me divert your attention for a second. Today you have in the arXiv a nice paper looking at the intracluster light of Abell 2390 with Euclid! @ec-euclid.bsky.social #astronomy #space

The next #Ariane6 flight #VA263 is now scheduled for 6 March at 13:24 local time (16:24 GMT, 17:24 CET). The investigations carried out on the ground equipment interfacing with the launcher following the launch attempt on 3 March now allow Arianespace to target this new launch date.

Later today, the first commercial launch of an #Ariane6 rocket is planned, after the maiden flight in July 2024 that was mostly successful. Ariane 6 was had been the backup launcher for #Euclid for many years. #space #astronomy 1/4

We are very happy to announce that #Euclid's Einstein Ring in NGC6505 is Astronomy Picture of the Day: apod.nasa.gov/apod/ap25022... #astronomy #ESA #NASA #APOD #science

Very nice zoom-out from our recently discovered Einstein Ring in the very center to the whole galaxy NGC 6505. On @esa.int`s Instagram: www.instagram.com/reel/DGTUyum... #science #space #astronomy

🎵 If you warp space due to the combined massive gravitational field of billions of stars in a chance alignment with Earth then you should've put a ring on it 🎶 badastronomy.beehiiv.com/p/einstein-p... 🔭🧪

We would like to welcome and thank our follower number 1000 (as well as the other 999) for your interest in #Euclid, our science, and the diverse set of people behind the mission! 🎉🔭🚀🛰️🍾

📸 🔭 Check out our week in images 10-14 February 2025 ➡️ www.esa.int/About_Us/Wee...

Always good to see interesting science news reported in mainstream newspapers (so often a science desert🤦🏻‍♂️) so well done @theguardian.com for the @esascience.esa.int #Euclid story and it even features @stephenserjeant.bsky.social 👏👏👏👍 #astronomy

And as usual with #ESAEuclid, both the full scene of NGC 6505 and its environment and background are visible in the same image, as well as the Einstein Ring in the center. But you have to zoom in! Images in our blogpost www.euclid-ec.org/einstein-rin... and at ESA www.esa.int/Science_Expl... 🔭

The combination of #ESAEuclid's spatial resolution and sensitivity of these observations shows the central Einstein Ring in NGC 6505 so clearly that it almost looks painted. But it is being created by gravity. #astronomy #space #science

Scientists with #ESAEuclid have discovered an Einstein Ring gravitational lens in a nearby NGC galaxies - something very rare, unexpected, and beautiful. NGC 6505 bends space, turning the image of a background galaxy into a ring. Read more: www.euclid-ec.org/einstein-rin... 🔭 #space #science
