Official Consortium of ESA's Euclid mission on the Universe's dark matter, energy & expansion, 14 European countries + USA + CAN + JAP, 2000+ scientists + engineers. Telescope successfully launched 1 July 2023 and now arrived at L2. Commissioning completed, calibration still running over the next weeks. First colour images released!

Finally, after months of work, the Early Release Observation images, data, first science results, and mission reference papers have been released. You can read more in our blog post, which has links to the papers, the press releases, and everything else:

In 45min (noon CEST today) and the @ec_euclid will release 5 more Early Release Observation images to the world. Accompanied by the first release of Euclid ERO science data, as well as 15 reference and science papers.

Tomorrow, 23 May, 12:00 CEST, and the @ec_euclid will present 15 papers, including first results:

5x reference papers about the main mission, the instrumentation, and related cosmological simulations

10x Early Release Observation papers, ranging from ... near to far

At the same time ESA will make 5 new ERO images public and the underlying science images. This programme was observed before the start of Euclid's main survey.

Stay tuned!

1112 authors for a space mission 🛰️ reference paper seems ... adequate 🤷🏽😯😁

We, the @ec_euclid will publish five main reference papers aimed at the astronomy community about the mission, the instruments, both cosmology and other astronomy science possibilities, as well as the cosmological simulations used to test all procedures.

Available coming Tuesday, 23 May, 12:00 CEST (and on arXiv a few hours later). Stay tuned!

Coordination of 100 to 1000 co-authors is actually quite a logistical feat. For this the @ec_euclid has a dedicated membership and author database, to keep contact info and affiliations up to date, and to manage the author lists of already more than 100 publications.

The upcoming release this week has still required a lot of work behind the scenes.

@ec_euclid@astrodon.social avatar

Expect new images and first science results from coming Thursday, 23 May. Five new stunning images, first ten science papers plus five reference publications.

There will be broadcast by as well as press and paper releases by ESA and us. Stay tuned!

What is ? It's a physics experiment and an space mission 🛰️ - but foremost it's a project imagined, designed, built, and operated by more than 2000 scientists, engineers, and technicians 👩‍🔬 👨‍💻 👩‍🔧.

We are now starting a series of -posts showcasing a cross-section of the people behind

First up:

Valeria Pettorino, ESA Euclid Project Scientist

and

Virginia Ajani, Scientist in the Interscience Task Force for Likelihood

You might recently have heard about ice buildup on 's mirrors? 🧊 This was expected from experience with previous missions also for and "de-icing" procedures were developed before launch and now refined. They involve warming up mirrors by a few 10°C. 🌡️

has now carried out the first de-icing campaign - and Euclid gained 15% of sensitivity within a few minutes. ✅

All the background, links to info, and an interview here:

#Euclid is a #space #telescope 🛰️ to escape #Earth's atmosphere, absorbing infrared-radiation and creating wobbly images. But space also has "weather". Given the currently active #sun 😎 and warnings of "geomagnetic storms" here's an intro blog post into "space weather" 🌪️ and how it affects the #ESAEuclid satellite.

We wish everyone around the globe a good start into 2024. The closing year 2023 marked a central milestone for us, the successful and of .

2024 will surely provide new challenges, but foremost the start of our sky surveys! In the next 12 months will observe more than 2000 square degrees of the sky with hundreds of millions of and . The data floodgates will open - and amazing science will result!

Wow, a week ago released the first full-colour images from our mission. We ourselves are still impressed, but apparently so were others 😯. We collected a number of media reactions on our website:

👉 https://www.euclid-ec.org/public/media-response/

From France to the UK, from Germany to Spain, from Brasil to S. Korea and Slovenia to the USA.

Now that our own excitement 🥳 about the #ESAEuclid Early Release Observation images, well, not subsides, but has changed from "we'll soon have great images" to "I want to go back to ESA Sky and browse some more", we notice that we aren't alone.

#ESA's webstory about the image release has already had more than 250,000 visitors, let's see if (or when 😉) we'll exceed the #JWST first image release (300,000):

Today's Astronomy Picture of the Day. Our image of the Perseus Cluster 🙂:

OK, hive mind.

I'm a galactic star formation astronomer, so not really one for distant galaxies 🤷‍♂️

But this snippet of the Perseus cluster from today's Euclid Early Release Observations has piqued my curiosity 🧐

Is that hourglass-shaped galaxy (?) near to NGC1275, the biggest in the region, known? I've checked & it's in other images, so surely it must be.

And what about that weird little wrapped pair at the end of a filament from NGC1275? Chance alignment?

@spacegeck @markmccaughrean

Has the 26k x 26k map of the cluster also been published? Because so far we've only seen the 8x8k and we think that's also in ESA Sky. One might be able to see more in the higher-res image.
