ESA’s Euclid captures the Milky Way’s crowded heart
For just one day, our dark Universe detective, Euclid, turned its gaze towards the light: the extremely bright inner region of our Milky Way galaxy, known as the galactic bulge. ...
The mission
ESA's Euclid mission is designed to explore the composition and evolution of the dark Universe. The space telescope will create a great map of the large-scale structure of the Universe across space and time by observing billions of galaxies out to 10 billion light-years, across more than a third of the sky. Euclid will explore how the Universe has expanded and how structure has formed over cosmic history, revealing more about the role of gravity and the nature of dark energy and dark matter.

Euclid discovers the most ancient quasar in the Universe
The European Space Agency’s Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed in cosmic history. They shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age.
Euclid discovers new comet
The European Space Agency’s Euclid space telescope has discovered its first previously unknown comet, in images taken between 16 and 24 September 2026.
Euclid opens data treasure trove, offers glimpse of deep fields
On 19 March 2025, the European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Here, hundreds of thousands of galaxies in different shapes and sizes take centre stage and show a glimpse of their large-scale organisation in the cosmic web.
