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.Read more

Milky Way galaxy's centre as seen by Euclid 01-Jul-2026
Thousands of planets are hidden in this photo
Millions of stars. Thousands of hidden worlds. One unprecedented view of our galaxy.
Three years since launch, ESA's Euclid space telescope reveals the Milky Way galaxy's centre in extraordinary detail: a mosaic of tens of millions of stars captured in just 26 hours. But this is more than an image. It is a map of stellar evolution, from dark clouds where stars are being born to ancient populations packed into the galactic bulge.Read more

Euclid Quick Data Release 2
The largest and most detailed photo ever made of our Milky Way galaxy's centre in visible light is revealed on 24 June 2026 by the European Space Agency's Euclid mission.Read more

Euclid Data Release DR1: update
We would like to share an update on the Euclid Data Release 1 (DR1) timeline for the scientific community. In order to maximise the scientific value of an exceptionally rich dataset, the release will proceed in two stages. Read more

Euclid starts seeing darkness
Euclid‘s core mission to study the nature of dark energy includes two central probes: one is tracking the expansion history of the Universe, the other traces structure formation over cosmic time. Ahead of the first cosmology results coming out in 2027, scientists have now published a first demonstration that Euclid can indeed trace massive structures dominated by usually invisible dark matter, using the technique of ‘weak gravitational lensing’.

NGC 6397 study. 03-Jun-2026
Scientists used Euclid data to study NGC 6397, one of the closest globular clusters to Earth.
In a serendipitous discovery, STScI scientists using the Euclid space telescope have for the first time found a red-dwarf brightness “gap” feature in the population of a globular cluster—an ancient, crowded collection of stars.

Euclid Space Warps 21-Apr-2026
Euclid Space Warps: help spot galaxies bending spacetime
With the launch of Space Warps, a new citizen science project on the Zooniverse platform, you can now join in the search to find rare and elusive strong gravitational lenses in never-before-seen images captured by the European Space Agency’s Euclid space telescope. The project aims at shining a light on dark matter in galaxies and providing clues about mysterious dark energy.

The image a planetary nebula in space and its surroundings. A star in the very centre is surrounded by white bubbles and loops of gas, all shining with a powerful blue light. Farther away a broken ring of red and blue gas clouds surrounds the nebula. The background shows many stars and distant galaxies. A white box indicates the centre of the nebula. 03-Mar-2026
Hubble & Euclid zoom into cosmic eye
For this month's ESA/Hubble Picture of the Month, NASA/ESA's Hubble Space Telescope is joined by ESA's Euclid to create a new view of the most visually intricate remnants of a dying star: the Cat's Eye Nebula, also known as NGC 6543.
This extraordinary planetary nebula in the constellation Draco has captivated astronomers for decades with its elaborate and multilayered structure. Observations with ESA's Gaia mission place the nebula at a distance of about 4300 light-years.

Hubble, Euclid & Subaru uncover dark galaxy
Employing NASA/ESA Hubble Space Telescope in combination with ESA Euclid and ground-based NAOJ Subaru Telescope, astronomers identified a galaxy that appears to be almost entirely dominated by dark matter with only a smattering of stars. The galaxy, known as Candidate Dark Galaxy-2 (CDG-2), appears to contain just four globular star clusters (compared to the Milky Way's 150-plus), and dimly shines with the light of only about 1 million Suns.
