Proba-2 sees the Moon eclipse the Sun
Video: 00:00:31 ESA’s Proba-2 captured two partial solar eclipses on 8 April 2024. A solar eclipse occurs when the Moon passes between Earth and the Sun, totally or partially blocking the Sun from Earth’s point of view. On 8 April, lucky viewers across North America witnessed the Moon blocking out the Sun in its entirety […]
Euclid mission team honoured with Space Foundation Award
Image: 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, […]
Webb probes galaxy teeming with newborn stars
The NASA/ESA/CSA James Webb Space Telescope has set its sights on the starburst galaxy Messier 82 (M82), a small but mighty environment that features rapid star formation. By looking closer with Webb’s sensitive infrared capabilities, a team of scientists is getting to the very core of the galaxy, gaining a better understanding of how it […]
Mars Express celebrates 25 000 orbits
ESA’s Mars Express recently looped around Mars for the 25 000th time – and the orbiter has captured yet another spectacular view of the Red Planet to mark the occasion. To source
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 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 […]

Gaia unravels the ancient threads of the Milky Way
ESA’s Gaia space telescope has further disentangled the history of our galaxy, discovering two surprising streams of stars that formed and wove together over 12 billion years ago. To source
Webb & Hubble confirm Universe’s expansion rate
Webb measurements shed new light on a decade-long mystery. The rate at which the Universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos. However, a persistent difference, called the Hubble Tension, is seen between the value of the constant measured […]
Webb: galaxy mergers solve early Universe mystery
One of the key missions of the NASA/ESA/CSA James Webb Space Telescope is to probe the early Universe. Now, the unmatched resolution and sensitivity of Webb’s NIRCam instrument have revealed, for the first time, what lies in the local environment of galaxies in the very early Universe. This has solved one of the most puzzling […]
Webb discovers dusty cat’s tail in Beta Pictoris system
Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study. It possesses the first dust disc imaged around another star – a disc of debris produced by collisions between asteroids, comets, and planetesimals. To source
Galactic Chloé – the Gaia mission
Video: 00:12:29 For Gaia’s 10-year anniversary, ESA champion Galactic Chloé and the ESA Gaia team are very happy to collaborate to tell the space mission’s story. From paper calculations, to the launch, and to her third data release last year, discover three of the mission’s most surprising discoveries and celebrate with us Gaia’s birthday with this video produced by Galactic Studios!
