Euclid satellite 30-May-2024
New de-icing operation begins
After the successful ice decontamination procedure performed in March, ESA's Euclid operation team, along with partners in science and industry, has been continuously monitoring the health of Euclid's science instrumentation. As expected, water ice remains inside the cavity where the instruments are hosted.

Euclid's First Science 23-May-2024
ESA's Euclid celebrates first science with sparkling cosmic views
Today, ESA's Euclid space mission releases five unprecedented new views of the Universe. The never-before-seen images demonstrate Euclid's ability to unravel the secrets of the cosmos and enable scientists to hunt for rogue planets, use lensed galaxies to study mysterious matter, and explore the evolution of the Universe.
The new images are part of Euclid's Early Release Observations. They accompany the mission's first scientific data, also made public today, and 10 forthcoming science papers. The treasure trove comes less than a year after the space telescope's launch, and roughly six months after it returned its first full-colour images of the cosmos.

Space Foundation Award 09-Apr-2024:
Euclid mission team honoured with Space Foundation Award
The Euclid mission team was awarded this year's Space Achievement Award by the Space Foundation, a non-profit organisation founded in 1983 to foster collaboration across the global space community. ESA Director General, Josef Aschbacher (centre), and ESA Director of Science, Carole Mundell (right), collected the prize at the Space Symposium in Colorado Springs, USA

Euclid's sight restored 26-Mar-2024
Euclid's sight restored
A newly devised procedure to de-ice Euclid's optics has performed significantly better than hoped. Light coming in to the visible 'VIS' instrument from distant stars was gradually decreasing due to small amounts of water ice building up on its optics. Mission teams spent months devising a procedure to heat up individual mirrors in the instrument's complex optical system, without interfering with the finely tuned mission's calibration or potentially causing further contamination. After the very first mirror was warmed by just 34 degrees, Euclid's sight was restored.

Euclid starts de-icing 19-Mar-2024
Operations begin to de-ice Euclid's vision
A few layers of water ice – the width of a strand of DNA – are starting to impact Euclid's vision. After months of research, Euclid teams across Europe are now testing a newly designed procedure to de-ice the mission's optics.

Update 20 March: First results confirm successful operations Euclid's sharp vision is restored. The initial analysis of Euclid's data validates the de-icing approach devised by the team. A more in-depth analysis of the results is ongoing and an update will follow in the coming days.

Dark Universe Survey 14-Feb-2024
Ready, set, go! Euclid begins its dark Universe survey
Today, ESA's space telescope Euclid begins its survey of the dark Universe. Over the next six years, Euclid will observe billions of galaxies across 10 billion years of cosmic history. Learn how the team prepared Euclid in the months after launch for this gigantic cosmic quest.

Astro Awards 2024 14-Jan-2024
Congratulations to ESA's Euclid team for the recognition they received at the Astro Awards 2024!
On January 14, 2024 at the Paramount Theatre, Austin, Texas, the Everyday Astronaut team hosted their first in-person event and awards show. Their mission, to honor and celebrate the revolutionary humans behind the hardware and missions by inviting them to accept an award IN REAL LIFE! And Euclid was there!
