In Brera (Milan) to present how @elsa-euclid.bsky.social will use AI to study galaxies! @ec-euclid.bsky.social

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 🔭

Beautiful comparison of @ec-euclid.bsky.social's infrared view of an interstellar dark cloud, compared to what we see in optical light 🧪🔭 www.youtube.com/watch?v=MlmQ...

wow....

The solar flare that caused aurora here on Earth a few days ago, also caused a blizzard of particle impacts on @ec-euclid.bsky.social's detectors. Very nice explainer by @james4cet.bsky.social www.euclid-ec.org/here-comes-t... 🧪🔭

Blog post by @ec-euclid.bsky.social PhD student Ruby Pearce-Casey from her #DISCnet industry placement with #KeenAI, deploing her AI skills to new areas. Earlier, Ruby made a breakthrough in finding strong gravitational lenses in Euclid imaging using machine learning keen-ai.com/blog/anticip... 🧪🔭

Very nice blog post by my grad student Ruby Pearce-Casey (who's done excellent @ec-euclid.bsky.social work on finding strong gravitational lenses), from her #DISCnet industry placement with #KeenAI 🧪🔭 keen-ai.com/blog/anticip...

Let me tell you, our officially-not-an-X-ray-telescope #ESAEuclid did notice this flare. Very much so. A gazillion cosmic ray hits, plus a shadow of hardware where the instruments aren't fully X-ray shielded. I mean this was the 39th (?) strongest flare in 30 years.

Whoa. The scale of this thing. That blast wave radiating away from the flare location is impressive. Esp. when you think about the size of the Earth in comparison. It’s so very near that we live so close to a star and can watch its behaviour and activity. A star and it’s just right there!

Many new @ec-euclid.bsky.social papers have just been released too, including this beautiful morphological tuning fork of galaxies 🔭🧪 This page is interactive - have a play! www.euclid-ec.org/euclid-morph...

Some marvellous @ec-euclid.bsky.social press releases just out! A beautiful image of a shimmering infrared dark cloud observed with Euclid www.esa.int/ESA_Multimed...

Rather lovely blog marking the second anniversary of the launch of @ec-euclid.bsky.social, by @knudjahnke.bsky.social www.euclid-ec.org/second-anniv... 🔭🧪

"Almost dark galaxy" discovered with the help of the @ec-euclid.bsky.social archive - press release in English 🧪🔭 www.statistics.utoronto.ca/news/candida...

New Euclid archive result: discovery of an "almost dark galaxy" with four globular clusters. Wonderful to see the community make great use of the @ec-euclid.bsky.social archive! Press release (in German): 🔭🧪 www.uibk.ac.at/de/newsroom/...

A short 🧵 on some lovely Euclid-relevant Sixty Second Adventures, commissioned earlier by ELSA project members and narrated by the excellent David Mitchell 🧪🔭 The Big Bang: www.youtube.com/watch?v=6bPL...

The mathematical poet Piet Hein wrote this lovely poem about Euclid, titled Parallelism 🧪🔭 /cc @ec-euclid.bsky.social "Lines that are parallel meet at Infinity!" Euclid repeatedly, heatedly, urged. Until he died and so reaching that vicinity in it he found that the damned things diverged.

On the other microblogging site (no, not that one, the _other_ other microblogging site), the astrodon.social server is being decommissioned, so we've migrated our Mastodon account and moved most of its content over to mastodon.social/@elsa_euclid . Come and say hello! 🧪🔭

We're planning a citizen science project for volunteers to rummage the spectroscopic data from the ESA Euclid mission. Watch this space (metaphorically, and in time, literally) @science.esa.int @ec-euclid.bsky.social 🧪🔭

The new EULICD data release is AMAZING! 🔭 Here's a before / after of a random galaxy I found in one of the new images, comparing against the Digitized Sky Survey. I highly recommend taking a look around on ESA Sky - it's fun! Link: sky.esa.int/esasky/?targ...

Okay, we’re sorry…it’s a school night, we know… But, stick with us, because we’ve got a case of the zoomies! 🔍 Here’s an area of Deep Field South zoomed in 16x 🌌 (1/3)

We’re delighted to share that Galaxy Zoo (and you!) are featured in the first Euclid data release announced today! Read more: blog.galaxyzoo.org/2025/03/19/g... 🔭

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

🌌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.

Watch this great explainer by one of our #EuclidUK scientists, @stephenserjeant.bsky.social ⬇️ 💍

Beautiful gravitational lens in our cosmic doorstep discovered by the @ec-euclid.bsky.social . In the future, Euclid's spectroscopy will give us new windows into these warps in space and time. @esa.int press release: www.esa.int/Science_Expl... 🧪🔭

Our ELSA meeting conference, after a few days playing with Euclid @ec-euclid.bsky.social spectroscopy. We're enjoying the cognitive dissonance of being in a 18th century building working on a 21st century space telescope 🧪🔭

We're so excited to be here at #AAS245! 🤩 We have a busy week ahead with lots of Rubin-related sessions and even more talks throughout the week ✨ Don't miss these sessions! You can also find us all week in the exhibit hall at booth 105A in the NSF pavilion 🔭🧪 🧵

At #AAS245 you will find the special session "241 - The Euclid Mission: First Results and Opportunities for Archival Research" on Tuesday, January 14, 2:00-3:30 PM, in National Harbor 10. Five presentations on the current state of Euclid and it's upcoming first science data release. #astronomy

Our annual ELSA meeting has kicked off! Beautiful location in Bristol University’s Goldney House, which looks like it’s straight out of Downtown Abbey

A very warm welcome to @esa.int ! 🔭🧪

Happy holidays from the @ec-euclid.bsky.social and the Euclid ELSA project

A look back at #ESAEuclid in 2024, and a look forward into what to expect from #Euclid in the coming year: www.euclid-ec.org/euclid-in-20... #astronomy #science #space

A common theme of many of the excellent talks at the @ec-euclid.bsky.social @eucliduk.bsky.social meeting today has been application of machine learning technologies: cGANs, Bayesian CNNs etc. Also many examples where human input via citizen science is crucial to the ML workflows for truth sets 🧪🔭

Today is Day 1 of #EuclidUK2024, where scientists from across the UK are meeting to share their latest updates about the pioneering Euclid Space Telescope! Thanks to the @royalastrosoc.bsky.social for hosting - a beautiful venue 😍

Congratulations to @ec-euclid.bsky.social member Ruby Pearce-Casey - her excellent paper on finding strong gravitational lenses with #MachineLearning has been very nicely covered by this #YouTube video - an unexpected but lovely surprise 🧪🔭 www.youtube.com/watch?v=XZKz...

Would you like to spot warps in space and time? The @ec-euclid.bsky.social #Euclid space telescope consortium needs your help! With this help from you, ELSA will unpick what's going on in newly-discovered magnified background galaxies with Euclid's spectroscopy 🧪🔭 www.zooniverse.org/projects/apr...

Very happy to see my grad student Ruby Pearce-Casey's first fully refereed paper at number 1 on the arXiv mailing this morning - and it's a beautiful piece of work, a big step forward in machine learning/AI methods to find strong gravitational lenses 🧪🔭 arxiv.org/abs/2411.16808

#ESAEuclid's 'Space Warps' #citizenscience search for gravitational lenses is still running. You can participate! www.euclid-ec.org/space-warps-... #astronomy #ESA #Euclid #space

Celebrate World Space Week with sparkling cosmic views – courtesy Euclid, the powerful European space telescope! Launched on 1 July 2023, Euclid will create the most extensive 3D map of the universe yet, to uncover some of its hidden secrets. Learn more → europa.eu/!QFVgqc

Were happy to announce #Euclid #SpaceWarps - our first citizen science search for gravitational lenses in #ESAEuclid data. Curious? Join our #CitizenScience project on the #Zooniverse: www.zooniverse.org/projects/apr... #astronomy #space #science #cosmology

This is one really big area of @ec-euclid.bsky.social Legacy Science that absolutely needs human eyes. The very best machine learning gravitational lens finders make lens-candidate lists that are just 10% pure, ie 1 lens comes with 9 false positives. We need your 👀! 🔭🧪 bsky.app/profile/elsa...

We're delighted to announce a new citizen science project: SPACE WARPS - ESA EUCLID. Browse the @ec-euclid.bsky.social data and be the first to discover warps in space and time! www.zooniverse.org/projects/apr... 🧪🔭
