The first Euclid data published by ESA (Q1) provide impressive insights into the depths of the universe. They include high-resolution images of 26 million galaxies, reveal the finest structures and make it possible for the first time to precisely determine the shape and distance of more than 380,000 galaxies. This data is a milestone and yet only marks the beginning of research into dark matter and dark energy. And the Max Planck Institute for Extraterrestrial Physics (MPE) plays a central role in all of this. more

A team of scientists has found the largest superstructure ever reliably characterised in the universe. The discovery was made while mapping the nearby universe using galaxy clusters detected by the ROSAT X-ray satellite's survey of the sky. With a length of about 1.4 billion lightyears, the new structure, which consists mainly of dark matter, is the largest known structure to date. Researchers at the Max Planck Institute for Extraterrestrial Physics (MPE) and the Max Planck Institute for Physics (MPP) led the study in collaboration with colleagues in Spain and South Africa. more

Researchers have finished equipping the Subaru Telescope with a new special “compound eye” culminating several years of effort. This new instrument features approximately 2,400 fibers scattered across the extremely wide field of view available at the Subaru Telescope’s primary focus, allowing for simultaneous spectroscopic observation of thousands of celestial objects. This unrivaled capability will help researchers precisely understand the formation and evolution of galaxies and the Universe once it begins scientific operations in February 2025.

Euclid, ESA’s newest space telescope with strong German participation, has delivered its first test images a few weeks after the rocket launch. more

The ESA space telescope Euclid, with significant contributions by the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching, was launched into space today, 1 July 2023 at 17:12 CEST on a Falcon 9 rocket by the US space company SpaceX. Once it arrives at its destination, the Lagrange Point 2 (L2) of Earth-Sun system, it will observe over a third of the entire sky for at least six years, mapping the spatial distribution of billions of galaxies and measuring their properties. Analysing this data, the six German institutes in the international Euclid consortium hope understand better, how Dark Matter and Dark Energy influence the structure of the universe. more

Shortly before being shipped to the rocket launch, the Euclid project team took a last look at the impressive satellite that will soon map the distribution of galaxies in space more precisely than ever before. more

With a sophisticated combination of human and artificial intelligence, astronomers uncovered 1701 new asteroid trails in archival data of the Hubble Space Telescope spanning the past 20 years. While about one third could be identified and attributed to known objects, more than 1000 trails probably correspond to previously unknown asteroids. These unidentified asteroids are faint and likely smaller than asteroids detected in ground-based surveys. They could give the astronomers valuable clues about conditions in the early solar system, when the planets were formed. more
