Satellites in orbit underpin our modern lives. They are used in many areas and disciplines, including space science, Earth observation, meteorology, climate research, telecommunication, navigation and human space exploration. However, as space activities have increased, a new and unexpected hazard has started to emerge: space debris.
Twenty-five years ago, Copernicus set out to transform the way we see our planet. Now, well established as the largest environmental monitoring programme in the world, it returns a whopping 16 terabytes of high-quality data every single day. To mark a quarter-century of European success in space, we look back at a selection of 25 Copernicus highlights.

Dark matter, the invisible material that makes up the vast majority of the universe's mass, may collect itself to form atoms, a new simulation shows.
Astronomers have used the youngest objects in the Milky Way to build a new map of the galaxy's spiral arms, and the results are far messier than expected.
Parabolic flights produce reduced gravity by following a wild trajectory of steep climbs and nerve-racking dives. The experience is out of this world, but for this reporter it had its challenges.
Astronomers have discovered the first chemical evidence of pair-instability supernovae from the universe's earliest massive stars in a strange star in the Milky Way’s galactic halo.
The Mars Express orbiter, the European Space Agency’s (ESA) first interplanetary mission, entered orbit around Mars on June 2nd, 2003. Since then, the probe has mapped the Martian surface using its High-Resolution Stereo Camera (HRSC), an instrument built by the German Aerospace Center (DLR) with commercial partners. In honor of the mission’s 20th anniversary, a celebration occurred last Friday (June 2nd) at the ESA’s European Space Operations Center (ESOC) in Darmstadt, Germany.
Several million years ago, the core of our galaxy experienced a powerful event. It blew out a huge bi-lobed bubble that blasted through the interstellar medium in two directions. Whatever it was, it released huge amounts of energy from the central supermassive black hole, Sagittarius A* (Sgr A* for short).
When astronomers used the JWST to look at a galaxy more than 12 billion light years away, they were also looking back in time. And when they found organic molecules in that distant galaxy, they found them in the early Universe.
The Rocket Lab's pioneering private mission to Venus, which had been set to launch last month, has been delayed until at least 2025.
Satellites watched as floodwaters ravaged southern Ukraine following the mysterious collapse of a major dam on Tuesday (June 6).
Massive, dying stars — behemoths tens of times the Sun's mass — should emit gravitational waves that we can hear with LIGO.
Astronomers have created the first model for how debris around exploding stars could emit gravitational waves powerful enough to be detected by instruments on Earth.

Everyone remembers The Matrix but there’s another, lesser known movie that delved into the murky world of artificial reality. And it deserves better than to be forgotten.
New technologies utilizing material found in space are constantly popping up, sometimes from smaller companies and sometimes from larger ones. Back in 2020, one of the largest companies of them all announced a technology that could have significant implications for the future lunar exploration missions planned over the next ten years. The European aerospace giant Airbus developed the Regolith to OXYgen and Metals Conversion (ROXY) system.
