Hallo C/2026 S1 (Euclid), nice to see you!

. @ESA_Euclid discovers its first comet ☄️

That's quite impressive for a #DarkUniverse detective 🕵️ meant to take deep, steady images of distant galaxies, not fast-moving tiny objects.

A black-and-white telescopic view of deep space shows a faint comet, labelled “C/2026 S1 (Euclid),” moving slowly against a background of stars. An arrow points to the comet’s bright central core and short tail. A timestamp updates as the animation progresses, highlighting the comet’s motion over time. Orientation markers and a scale bar provide celestial directions and distance.

@ESA_Euclid has discovered the oldest quasars ever found.

📣 Most ancient quasars ever found!

@ESA_Euclid has discovered 31 ancient quasars. Two of them shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age.

This collage with observations of the Euclid space telescope shows a grid of small, dark panels filled with tiny points and faint smudges of light. The lights vary in brightness and colour, including white, blue, yellow, and orange, with some appearing as dots and others as slightly blurred shapes. Each panel has a small label with letters and numbers at the bottom.

It’s #AsteroidDay! Did you know that the Dark Universe detective can also help to measure asteroid rotation periods? Check it out in this recent paper: aanda.org/articles/aa/fu…

Well done @ESA_Euclid VIS camera, making individual stars visible in such a crowd!

This is the heart of the Milky Way, zoomed in ten times compared to the full image.

Despite the super-crowded area, Euclid's visible light camera can tell individual stars apart – without being blinded by the chaos.

5/8
A very dense field of tiny, closely packed points of light fills the image. The colour is almost uniform, dominated by bright yellow and gold tones across the entire frame. Small white points appear slightly brighter here and there, with a few faint bluish points scattered among them. No large dark patches or strong colour variations are visible, giving the image a smooth, grain like appearance.
