Last starlight for ground-breaking Gaia
The European Space Agency’s Milky Way-mapper Gaia has completed the sky-scanning phase of its mission, racking up more than three trillion observations of about two billion stars and other objects over the last decade to revolutionise the view of our home galaxy and cosmic neighbourhood. To source
The best Milky Way animation, by Gaia
Video: 00:02:05 This is a new artist’s animation of our galaxy, the Milky Way, based on data from ESA’s Gaia space telescope. Gaia has changed our impression of the Milky Way. Even seemingly simple ideas about the nature of our galaxy’s central bar and the spiral arms have been overturned. Gaia has shown us that it has […]
ESA’s Highlights in 2025
This year will mark the European Space Agency’s 50th anniversary and promises to be a landmark year for the European aerospace industry. In addition to milestone events in our programmes, September will also mark 30 years of satellite navigation for Europe. This spring brings the second commercial mission involving a project astronaut to the International […]
IRIDE pathfinder satellite has launched
The first IRIDE satellite – the Pathfinder Hawk – is now in orbit around Earth after lifting off on a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California on 14 January. As its ‘Pathfinder’ name suggests, this new microsatellite is a prototype for one of the six IRIDE constellations, which are […]
BepiColombo's sixth Mercury flyby: the movie
Video: 00:01:36 Fly over Mercury with BepiColombo for the final time during the mission’s epic expedition around the Sun. The ESA/JAXA spacecraft captured these images of the Solar System’s smallest planet on 7 and 8 January 2025, before and during its sixth encounter with Mercury. This was its final planetary flyby until it enters orbit […]
XMM-Newton catches giant black hole’s X-ray oscillations
The European Space Agency’s XMM-Newton has detected rapidly fluctuating X-rays coming from the very edge of a supermassive black hole in the heart of a nearby galaxy. The results paint a fascinating picture that defies how we thought matter falls into such black holes, and points to a potential source of gravitational waves that ESA’s […]

Top three images from BepiColombo's sixth Mercury flyby
On 8 January 2025, the ESA/JAXA BepiColombo mission flew past Mercury for the sixth time, successfully completing the final ‘gravity assist manoeuvre’ needed to steer it into orbit around the planet in late 2026. The spacecraft flew just a few hundred kilometres above the planet’s north pole. Close-up images expose possibly icy craters whose floors […]
Los Angeles ablaze
