We followed up #ESAEuclid's near-infrared image of the Dark Cloud LDN 1641 with a comparison to the NIR 2MASS survey, and to a bespoke ground-based image in visible light.

Here's the comparison including a tool to experiment yourself:

Do you remember the 'Dark Cloud' image of LDN 1641 from #ESAEuclid that was released by @science.esa.int two weeks ago? We now added a comparison to a ground-based image in visible light:

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.

Reminder: @science.esa.int is hosting a workshop "Working with #Euclid Q1: from Data Access to Science" in a hybrid format at ESAC, Madrid, Spain, and online – from 1.-3. December 2025.

This event will bring together researchers with + without prior experience using #ESAEuclid data.

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. ⬛️☁️

#ESAEuclid peers through a dark cloud’s dusty veil to reveal a place teeming with very young stars ✨

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... 🔭
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.

We are releasing seven new science publications today, based on our Q1 data release earlier this year. All revolve around galaxies, from dust to interactions to active centers.These are accompanied by two new image collages drawn from the same release.

If you put your mind to it, you can accomplish anything.

This #BackToTheFutureDay, we’re celebrating the countdown to our first big data release (DR1) on 21st October 2026 - just one year to go until large pieces of #Euclid ‘s map of the Universe are released to the world! 🌍
