ELSA - Euclid

Would you like to rummage data from the Euclid space telescope, and uncover cosmic nurseries where stars like our Sun are born? We're delighted to announce our new @ec_euclid@mastodon.social citizen science project, Galaxy Zoo Clump Scout 2 #astrodon https://www.zooniverse.org/projects/hughdickinson/galaxy-zoo-clump-scout-ii

At the @ec_euclid@mastodon.social meeting, Pietro Bergamini showing narrow-band spectroscopic images of gravitational arcs - like from the beautiful galaxy cluster gravitational lens in his title slide here. The curved arcs are background galaxies seen through warped spacetime #astrodon

News from the Euclid Consortium Meeting in Barcelona:
Kudos to ELSA member Andrea Enia for winning the Euclid Star Prize (junior category)! #astrodon

Today the Euclid space telescope team are launching a new search for Space Warps! Come and be the first to find warps in space and time in Euclid's unseen Data Release 1, before the DR1 publication in October @ec_euclid@mastodon.social #astrodon

Paper day!! Very nice ELSA @ec_euclid@mastodon.social result by Fabrizio Gentile and team, using Euclid's huge dataset to unpick how galaxies' star formation, environment and morphology are connected. Just accepted by A&A #astrodon https://arxiv.org/abs/2511.02964

A happy and peaceful holiday season and a prosperous DR1 new year from @ec_euclid@mastodon.social in general and the ELSA team in particular #astrodon

The ELSA @ec-euclid.bsky.social team meeting this week in beautiful Bologna. Amazing things being done with Euclid spectroscopy - watch this space :) #astrodon

Beautiful comparison of @ec_euclid@mastodon.social's infrared view of an interstellar dark cloud, compared to what we see in optical light #astrodon https://www.youtube.com/watch?v=MlmQQMf4Gjs

The solar flare that caused aurora here on Earth a few days ago, also caused a blizzard of particle impacts on
@ec_euclid@mastodon.social's detectors. Very nice explainer by @james4cet.bsky.social #astrodon https://www.euclid-ec.org/here-comes-the-sun/

Many new @ec-euclid.bsky.social @ec_euclid@mastodon.social papers have just been released too, including this beautiful morphological tuning fork of galaxies. This page is interactive - have a play! #astrodon https://www.euclid-ec.org/euclid-morphological-tuning-fork/

Some marvellous @ec-euclid.bsky.social @ec_euclid@mastodon.social press releases just out! A beautiful image of a shimmering infrared dark cloud observed with Euclid #astrodon https://www.esa.int/ESA_Multimedia/Images/2025/11/Euclid_peers_through_a_dark_cloud_s_dusty_veil

"Almost dark galaxy" discovered with the help of the @ec_euclid@mastodon.social archive - press release in English #astrodon https://www.statistics.utoronto.ca/news/candidate-dark-galaxy-2-u-t-researchers-shine-new-light-universe%E2%80%99s-darkest-realms

Blog post by @ec_euclid@mastodon.social PhD student Ruby Pearce-Casey (who made a breakthrough in finding strong gravitational lenses), from her #DISCnet industry placement with #KeenAI https://keen-ai.com/blog/anticipating-geomagnetic-storms-reflections-at-the-halfway-point-part-2/ #astrodon

Many other @ec-euclid.bsky.social @ec_euclid@mastodon.social papers being released this week, including by Daniela Vergani and team on discoveries of galaxies with unusual emission lines - here's an explainer by @stephenserjeant.bsky.social @stephenserjeant@mas.to

‪Rather lovely blog marking the second anniversary of the launch of @ec_euclid@mastodon.social , by @knud@mastodon.social https://www.euclid-ec.org/second-anniversary-of-euclid-in-space/ #astrodon

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@mastodon.social archive! Press release (in German): #astrodon https://www.uibk.ac.at/de/newsroom/2025/dunkle-galaxie-im-perseushaufen-entdeckt/
