This new Euclid collage, based on the Q1 data set, presents 28 nearby galaxies observed by Euclid.
Each of the 28 galaxies can be explored directly in ESASky:

Those were beautiful #aurorae in the past days. A solar storm brought a lot of protons to Earth. Not only to Earth but also to #ESAEuclid – but does #Euclid notice? Oh yes.

New #Euclid image drop from @esa.int and @ec-euclid.bsky.social! 😍

Meet LDN 1641, a ‘dark cloud’ about 1300 light-years from Earth, observed by Euclid back in 2023 to test its guiding systems. ⬛️☁️

🔭🌌 Klarer Blick durch den galaktischen Nebel 👀: Das Weltraumteleskop #Euclid blickt durch eine Wolke aus Staub und Gas und zeigt unzählige junge Sterne ✨. Eines der 2 Instrumente des Teleskops (Near-Infrared Spectrometer and Photometer) wurde übrigens in 🇩🇪 entwickelt. 🛠️

📷 This shimmering view from the ESA Euclid mission shows the dark cloud LDN 1641. Though nearly invisible to the human eye, Euclid’s infrared vision uncovers a rich landscape of gas, dust and dozens of newborn stars🧪🔭

The focus of the image is a portion of LDN 1641, an interstellar nebula in the constellation of Orion. In this view, a deep-black background is sprinkled with a multitude of dots (stars) of different sizes and shades of bright white. Across the sea of stars, a web of fuzzy tendrils and ribbons in varying shades of orange and brown rises from the bottom of the image towards the top-right like thin coils of smoke.

While investigating the nature of the dark Universe, Euclid is also delivering observations such as this one that enable research in different fields of astronomy 👉 www.esa.int/ESA_Multimed... 🔭

In March, #ESAEuclid delivered its first batch of survey data, a treasure trove for research far beyond just the topic of dark matter & dark energy.

Thanks to its wide & deep view of the cosmos, Euclid will address questions from a broad range of topics 👉 www.esa.int/Science_Expl... 4/ 🔭 #CM25
A collage of nine by five squares containing galaxies of many different shapes and viewed in different orientations. For example, the first column shows five edge-on galaxies, which appear thin like a pencil. The galaxies in the second column have a more fuzzy, diffuse appearance. The middle columns showcase face-on spiral galaxies with many different shapes and densities of stars. The last two columns include interacting galaxies or galaxies with an unusual spiral arm or tidal tail.

Just over a year after launch, #ESAEuclid was delivering the first page of its great cosmic atlas.

A mosaic of 208 gigapixels capturing 100 million sources: stars in our Milky Way and galaxies beyond.

Just 1% of the wide survey that Euclid will capture over six years. 3/ 🔭

Part of our #CosmicVision plan, #ESAEuclid launched in 2023 on a quest to solve the mysteries of the dark Universe. 🔭

Its goal? Create a great map of the large-scale structure of the Universe across space and time by observing billions of galaxies. 1/ #CM25

To search for Earth-like planets our Plato mission will use 26 cameras in a design inspired by the compound eyes of insects.

The mission will spot any slight dimming or brightening of a star when a planet passes in front of it.

Learn more about Plato's 'eye' 👉 www.esa.int/Science_Expl... 🔭
In the photo three people in white overalls and caps stand in front of the instrumentation in a white hall. The equipment, about twice as tall as the people in the picture, consists of a black four-stepped-platform that supports 24 cameras. These resemble cylinders flaring at the top, not unlike big ice-cream cones. Each cylinder is wrapped in black material; the top flare has a metallic finish and a white lid.

If you want to spend some quality time with #Euclid data, you can use "ESA Sky", which allows everyone to browse public data, pan, zoom, and look around. All in full colour galore, and full resolution.
