Browsing through the #Euclid deep fields, and this struck my eye. Those look like some pretty impressive tidal tails!

Der Quick Release 1 des #Euclid-Satelliten - die ersten 63 von am Ende 14.000 Quadratgrad des Himmels - ist da: Das Video youtube.com/watch?v=rXCBFlIpvfQ taucht in die gigantische Himmelsdurchmusterung ein, und in skyweek.wordpress.com/2025/03/ gibt es ausgewählte Bilder, Hintergründe und viele Links. Richtig ernst wird es dann Ende 2026 mit dem Data Release 1, der 1900 Quadratgrad und die ersten fundamentalen kosmologischen Schlussfolgerungen verspricht, um die es bei dem ESA-Projekt geht.

"Dark energy is the name given to the cause of the accelerating expansion of the universe. This acceleration, discovered in the late 1990s, won the Nobel Prize in Physics.

#Euclid has exactly what it takes to respond unambiguously to [the possibility the “cosmological constant” could vary over time]."

[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! sky.esa.int/esasky/?hide_welco

What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...
