#Euclid scientists identified 31 new early Universe quasars, including the two most distant quasars currently known. The new record holder's redshift z=7.77 places it only 670 million years after the Big Bang. www.euclid-ec.org/most-distant... #ESA #ESAEuclid #astronomy #blackholes #science

📣 Most ancient quasars ever found! Euclid has discovered 31 ancient quasars. Two of them shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age. Discover more 👉 www.esa.int/Science_Expl... 🔭 🧪 ☄️

If you are in the London/UK area right now, #Euclid has an interactive exhibition at the @royalsociety.org's #SummerScience exhibition. Open until Sunday 5 July. See you there! #ESAEuclid #astronomy #space #research

Euclid, the dark universe has arrived at the @royalsociety.org's #SummerScience exhibition! Our team of scientists, engineers and public engagement professionals, ranging from undergraduate students to senior professors, will be here until Sunday...

60 million stars in just one image 🤯 @esa.int's Euclid mission has just released the most detailed visible light image ever of our galaxy's centre. See this image up close and meet some of the scientists behind it at our #SummerScience Exhibition next week: eucliduk.net/rssse.html

From depictions of science on the silver screen to what black holes look like up close and the art and ingenuity of feathers, here's what you can expect from the packed line up of talks and activities at the #SummerScience Exhibition this week: https://bit.ly/4vzOTA2

A year ago, #Euclid's first small data release 'Q1' provided data for 63 deg² of sky to the world. Now an 'Astronomy & Astrophysics Special Issue' has been published with 41 articles about and around this release: www.euclid-ec.org/q1-special-i... #astronomy #ESA #ESAEuclid #space #galaxies

Our Dark Universe detective 🕵️ earns its spot in ESA's June highlights – with the largest, most detailed image of the Milky Way's heart ever taken in visible light 👉 www.esa.int/Science_Expl... 🔭

#Euclid Q1 special issue is finally published in A&A 🎉 Big congrats to everyone who contributed! www.aanda.org/articles/aa/... New challenges with DR1 are already ongoing with full speed 😀 @ec-euclid.bsky.social @eucliduk.bsky.social @esa.int @de.esa.int

Wild to see the detail revealed by the #Euclid #Galactic Bulge Survey. Right side of the ESASKY image below shows a zoomed in edge of the EGBS area on the right, with adjoining Gaia DR3 data to the left. EGBS gives HST WFC3 level detail, but over an area 2000 larger! @eucliduk.bsky.social 🧪🔭

Erm... I might have just got a little bit too carried away on the BBC World Service, waxing lyrical about the gorgeousness of the @ec-euclid.bsky.social image of the heart of the Milky Way: "swirling golden cloudy fuzziness" "the cosmos scattered with glitter" 😂 ☺️🔭 📷: www.esa.int/Science_Expl...

🤩 Gorgeous image drop from @ec-euclid.bsky.social! 60 million stars = (roughly) >60 million exoplanets too.... Anyone else gazing at this image wondering what might be out there gazing back? 🤗 🥳 Huge congratulations to @science.esa.int and the whole Euclid team! 🧪🛰️🔭

Proud of the team I led during 2023-2025 when this survey was designed and executed. Very grateful to my @ec-euclid.bsky.social and @esa.int colleagues for allowing us to do something a little different from Euclid's day-to-day work. youtu.be/2DtFRq1cgcc?... Sound on, and ideally use a 4k screen!

No less than 60 million stars in one image. It's possible thanks to ESA's Euclid mission. For just one day, Euclid turned its gaze to the crowded heart of the Milky Way and captured the largest, most detailed photo ever taken of our galaxy's centre in visible light. Let's dive deeper 👇 🔭 🧪 ☄️ 1/8

It's #Euclid Q2 data release day! ESA and the EC are releasing an unusual dataset: a view into our Milky Way's bulge. There's a primer in this video: www.youtube.com/watch?v=2DtF... #ESA #ESAEuclid #astronomy #MilkyWay #stars #exoplanets 1/

🎄 Are your holiday decorations ready? Euclid has a cosmic garland to add: NGC 646. The large barred spiral galaxy appears close to a smaller galaxy to the left, but they’re actually about 45 million light-years apart 👉 https://www.esa.int/ESA_Multimedia/Images/2025/12/Euclid_s_galaxy_garland 🔭

Yannick Mellier, 1958–2025 www.euclid-ec.org/yannick-mell... #ESAEuclid #astronomy #space #ESA

Au revoir Yannick! Dear colleagues and friends, It is with the greatest sadness that we announce the passing of Yannick Mellier, which occurred during the night between Friday and Saturday. His death leaves a huge void within the consortium and our community. 1/3 #astronomy #space #ESA

Wishing you all a very happy holiday (as and when it starts for you) with this, the best-christmas-card-of-the-year, a gorgeous lino print of the Euclid Space Telescope! @eucliduk.bsky.social 🔭🎄 🙏👩‍🎨: @notverymedieval.bsky.social

We would like to wish everyone joyful holidays and a good start into the Euclid Data Release 1 year 2026. For more info about the image: www.euclid-ec.org/happy-holida... #astronomy #ESA #space #galaxies

Euclid, our #DarkUniverse 🕵️ detective, is hard at work creating a map of the large-scale structure of the Universe across space and time. What five mysteries is this detective trying to crack? Find out here 👉 www.esa.int/Science_Expl... 🔭

#HumansOfEuclid - Giuseppe Congedo (Edinburgh University) 🧵 (1/3) "I was in Italy on holiday at the time, but we watched it on YouTube, and it was really good fun. My children loved it. Everyone in the family followed it. But I was a bit nervous because I knew that my contract depended..."

Today is International Day of Persons with Disabilities #IDPwD. ESA keeps moving forward the conversation to break down barriers and make space and science accessible to all. #EveryoneIncluded #AccessibleWorld

We followed up #ESAEuclid's near-infrared image of the Dark Cloud LDN 1641 with a comparison to the NIR 2MASS survey, and to a bespoke ground-based image in visible light. Here's the comparison including a tool to experiment yourself: www.euclid-ec.org/clouds-darkn... #ESA #space #science 🔭

#HumansOfEuclid - Giuseppe Congedo (Edinburgh University) 🧵 (1/3) "I really hope Euclid will find something really new and change cosmology in an instant. But I do have a strong prior belief in [the standard model] Lambda-CDM. I think most of us have a fear that Lambda-CDM might be..."

Do you remember the 'Dark Cloud' image of LDN 1641 from #ESAEuclid that was released by @science.esa.int two weeks ago? We now added a comparison to a ground-based image in visible light: www.youtube.com/watch?v=MlmQ... #ESA #Euclid #astronomy #space 🧵

Remember that lovely aurora last week? Well...um...this is what Euclid saw... 😱 🧵

Those were beautiful #aurorae in the past days. A solar storm brought a lot of protons to Earth. Not only to Earth but also to #ESAEuclid – but does #Euclid notice? Oh yes. www.euclid-ec.org/here-comes-t... #ESA #Sun #SpaceWeather #space

#HumansOfEuclid - Carolyn Mill & Elena Silvestre Roselló 🧵 (1/4) “Yeah, being from Scotland, it's just so easy to just get immersed in the landscape. My dad started bagging Munros [Scottish peaks > 3000ft] when he was younger. And as soon as I could reliably carry my own rucksack, I joined him..

Reminder: @science.esa.int is hosting a workshop "Working with #Euclid Q1: from Data Access to Science" in a hybrid format at ESAC, Madrid, Spain, and online – from 1.-3. December 2025. This event will bring together researchers with + without prior experience using #ESAEuclid data. 1/ #ESA 🔭

New #Euclid image drop from @esa.int and @ec-euclid.bsky.social! 😍 Meet LDN 1641, a ‘dark cloud’ about 1300 light-years from Earth, observed by Euclid back in 2023 to test its guiding systems. ⬛️☁️

#ESAEuclid peers through a dark cloud’s dusty veil to reveal a place teeming with very young stars ✨ While investigating the nature of the dark Universe, Euclid is also delivering observations such as this one that enable research in different fields of astronomy 👉 www.esa.int/ESA_Multimed... 🔭

We are releasing seven new science publications today, based on our Q1 data release earlier this year. All revolve around galaxies, from dust to interactions to active centers.These are accompanied by two new image collages drawn from the same release. 1/ 🔭 #astronomy #space #ESA

Are you Curious About the Euclid Space Telescope? Take half an hour to watch the James from the @eucliduk.bsky.social outreach team talk all things space telescope and dark matter in today's #CuriousAbout session! curiousabout.glasgowsciencecentre.org/live-session...

Please bear with us as we take a short break from mapping the Universe to turn our attention to pumpkin carving… #DarkMatterDay #Halloween 🎃
