#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 🎃

Wherever you are, have a wonderful #DarkMatterDay! 🎃🔭

Seeing into Space (ages 8+) Tuesday 4 November 09.15am Join James from @EdinburghUni to uncover how the European Space Agency’s Euclid telescope is mapping a third of the sky - and the role Scotland is playing in this mission.   https://bit.ly/4nT3gMr #CuriousAbout

If you put your mind to it, you can accomplish anything. This #BackToTheFutureDay, we’re celebrating the countdown to our first big data release (DR1) on 21st October 2026 - just one year to go until large pieces of #Euclid ‘s map of the Universe are released to the world! 🌍

#HumansOfEuclid - Carolyn Mill & Elena Silvestre Roselló 🧵 (1/4) “I was choosing my bachelor thesis, randomly picked one and yeah, now she's my PhD supervisor! I could have ended up doing anything. Before that I was tempted to do translation. Like, I speak Catalan, Spanish and English..."

#HumansOfEuclid - Carolyn Mill & Elena Silvestre Roselló 🧵 (1/4) “I realized when I was doing my physics courses, I really started enjoying it when I first encountered cosmology in my final year. It just really clicked..."

#HumansOfEuclid - Konstantinos Tanidis 🧵 (1/2) “There’s something I have been thinking about recently. I remember before I started my academic career, during my Bachelor’s, I went to one of my astronomy professors and said I would like to start a project. And he asked me...

Its Doors Open Days at @uni-of-edinburgh.bsky.social! All weekend, find Euclideans at the Royal Observatory Edinburgh and learn more about how the #Euclid mission will transform our understanding of the Dark Universe. 🌀🔭🌌 #ROEopen

#HumansOfEuclid - Konstantinos Tanidis 🧵 (1/3) "“I was born in Thessaloniki, in Greece. When I was young in elementary school, yeah, I was obsessed with documentaries about astronomy and astrophysics. I was born in a city, but some weekends, I would go to the village of my grandparents...

#HumansOfEuclid: @cosmocora.bsky.social - Part 2 (1/5) 🧵 "I never wanted to be an astronomer - I don't have the story of, like, being fascinated by the stars when I was a kid. When I was 14 years old, I wanted to be a TV host...!"

#HumansOfEuclid (1/5) "By training, I’m a theorist. I come from quite a theoretical working group doing my PhD. There, I was used to being the most applied person just because I studied something that you could, at least in principle, observe - dark matter..."

We’ve got more #HumansOfEuclid for you to meet! 🕵️ 🌌 Get ready for the Leiden Entries, beginning this Friday, where we’ll feature some of the scientists we caught up with earlier this year at the @ec-euclid.bsky.social meeting. 🇳🇱

A time-lapse movie of our @eucliduk.bsky.social stand at the @goodwoodrrc.bsky.social Festival of Speed Future Lab last weekend! Visitors were zooming into data from ESA's Euclid Space Telescope, and using their body to make a gravitational lens to learn how astronomers search for dark matter.

Who's behind the research using Euclid data? Meet some of the scientists who work with data collected by our #DarkUniverse 🕵️ detective, ICYMI 👉 www.cosmos.esa.int/web/euclid/q... 🧪

Did you know it’s #NationalGuineaPigAppreciationDay? Meet Guinevere and Morgana, who couldn’t make the Goodwood #FestivalOfSpeed last week and decided to catch up on all the lensing they missed!

Take a whistle stop tour of @esa.int’s Euclid mission exhibit at this year’s GoodWood #FestivalOfSpeed with James, an Outreach Co-ordinator at The University of Edinburgh… (1/6) 🧵

And that’s a wrap for another day…see you tomorrow #FestivalOfSpeed!

Pleasure to be back at the Goodwood Festival of Speed Future Lab!

Some behind the scenes #Euclid filming with Tim Peake 👀 #FestivalOfSpeed

Had such a fun time explaining the wonders of @eucliduk.bsky.social to those at @goodwoodrrc.bsky.social yesterday! Time to spot some F1 cars today! 🏎️

🔭🧪😍

It’s Day 3 at the the @goodwoodrrc.bsky.social #FestivalofSpeed Future Lab. Our #HumansOfEuclid have had an early start, back and ready to share the mysteries of the dark Universe all over again! 🌌🕸️

The universe is in progress

Hanging out at the @eucliduk.bsky.social Future Lab exhibit at Goodwood Festival of Speed. Astronaut Tim peake popped by 🤩🧪🔭☄️

Good morning from the final day of #NAM2025! ☀️ There's lots going on today, from scientific sessions on @esa.int's @eucliduk.bsky.social and Gaia to a plenary from our president Professor Mike Lockwood on why diversity and inclusion are essential. ⤵️

Thanks to support from @esa.int and @sussex.ac.uk, #HumansOfEuclid from UK universities are at the Goodwood #FestivalOfSpeed! Today, Astronaut Tim Peake dropped by to learn about more about the Dark Universe. If you’re visiting #FOS near Chichester this weekend, be like Tim and come say hi!

It's time now for our final event of Day 1 at #NAM2025... Professor Isobel Hook, of @lancasteruni.bsky.social, is exploring the "massive mystery" that is dark energy. Here's a snippet of her public talk...

#ESAEuclid launched two years ago. This seems both like yesterday and a long time ago: www.euclid-ec.org/second-anniv... #astronomy #cosmology #space #science #Euclid

On this day, at this time, 2 years ago, #Euclid was successfully launched from Cape Canaveral, Florida, toward its home at L2 - a gravitational sweet spot in our Solar System that’s 1.5 million km away from us on Earth. Let’s look back at how some of our UK #HumansOfEuclid felt that day… #TBT 🚀

…are you ready for a #ThrowbackTuesday? (Yes, we’re making that a thing 😉) #TBT 🚀

… 🚀 …

Congratulations to @vrubinobs.bsky.social, and our UK based colleagues at @lsstuk.bsky.social, as they begin to #CaptureTheCosmos! 🥳 Together, Rubin and Euclid will help scientists unravel the mysteries of dark matter and dark energy. 🕸️
