Euclid will finish its map of the Universe in just six years, and sees as much with its camera in one day as Hubble sees in decades of operation. 👌

Indeed, Euclid covers a much larger area in every image compared to previous space telescopes. Hubble could carry out Euclid’s map of the Universe, but it would take hundreds of years! ⏳

This image highlights the Euclid space telescope’s remarkable ability to produce pin sharp images *and* capture a large portion of the sky reasonably quickly. 👌

Euclid then adds some much needed cosmological context, framing the Cat’s Eye Nebula in a playground of countless distant galaxies! 🌌

Beginning with a zoomed in view from Hubble, we see the very core of the gaseous afterlife of a star thanks to its high resolution visible-light image. 🔍

Hubble x Euclid 🤝

The two space telescopes join forces to create a breathtaking new view of the Cat’s Eye Nebula! 😍

Woah, that’s a lot of💥s!

People smiling holding certificates.

Super awards ceremony today, celebrating outstanding #scicomm & Physics public engagement in Edinburgh. Congrats @astr0mia.bsky.social, Ellie Bishop, Miquel Nebot-Guinot & Cheryl Patrick with honourable mentions for @eucliduk.bsky.social @ukbiofilms.bsky.social 🥳

At left, a field of space with a dozen white foreground stars and a number of small, yellow background galaxies. An unremarkable area at centre is outlined with a dashed circle surrounded by a white box. Lines extend from the box to a pullout at right containing faint, grainy white light surrounded by a circle labeled “Candidate dark galaxy – diffuse emission.” Four white dots are circled in blue and labeled globular clusters.

Hubble has joined forces with ESA's Euclid and NAOJ's Subaru Telescope in Hawaii to identify a galaxy that appears to be 99% dark matter!

Awesome, go Balgreen! 🙌

An image of space made by the Euclid telescope shows a bright barred spiral galaxywith two sweeping arms glowing in shades of blue and white against a deep black background dotted with stars. Its core is luminous. Its spiral arms curve gracefully outward to the left and down to the right, resembling a cosmic garland draped across the scene. A smaller, faint and round galaxy appears to the left of the barred spiral galaxy.

🎄 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

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.

Together, we will lino print the Universe! 😍

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 🔭🎄

Congrats, Leo! 👏

Holiday greeting image showing two large galaxies observed by the Euclid space telescope, a small Euclid sketch, and "Joyful holidays and happy DR1-year 2026".

We would like to wish everyone joyful holidays and a good start into the Euclid Data Release 1 year 2026.

Artist impression of the Euclid mission in space. The spacecraft is white and gold and consists of three main elements: a flat sunshield, a large cylinder where the light from space will enter, and a 'boxy' bottom containing the instruments. The spacecraft is shown half in the shadow, because the sunshield will always be faced in the direction of the Sun and thus protecting the telescope from the light of the Sun. The background is a realistic representation of a deep field view of the night sky, with many galaxies visible. On the bottom half of the image, an artistic representation of the cosmic web is overlayed over the galaxies. The cosmic web is the scaffolding of the cosmos on which galaxies are built, consisting primarily of dark matter and laced with gas. The cosmic web is here represented with a grid and a two-dimensional representation of a cosmological simulation.

Euclid, our #DarkUniverse 🕵️ detective, is hard at work creating a map of the large-scale structure of the Universe across space and time.

"... on it working. It was kind of a nerve wracking, knowing that your future basically depends on the success of this launch.

So, it was like, me on the rocket." (2/3)

The image is a head and shoulders portrait of a man wearing a brown woolly jumper, thick rimmed glasses, and a name tag. He is smiling, standing outside in the sunshine looking at the camera. There is a courtyard visible out-of-focus behind him.

"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..."
