Rethinking space junk in an age of satellite overload

From recycling old satellites in space to turning rocket parts into fuel or beaming debris back to Earth, researchers are exploring new ways to tackle the growing problem of space junk. By Jonathan O’Callaghan For decades, we have been littering space with decommissioned satellites and rocket parts orbiting our planet. Now this space debris poses a … Read more

Researchers turn ocean dead zones into talking skies for pilots

Researchers are developing satellite links that bring clear, real-time radio and data connections to flights over oceans, helping air traffic controllers keep routes safer and more efficient. By Michael Allen On 4 June 2025, air traffic controllers in Spain’s Canary Islands held a clear, uninterrupted conversation with a commercial pilot flying high above the Atlantic. … Read more

Hypothetical dark matter stars known as ‘boson stars’ could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. By Jonathan O’Callaghan In 2019, a strange event was observed in the depths of space. Called GW190521, the event sent out gravitational waves – invisible ripples in … Read more

Europe’s deep-sea telescope on a hunt for the origins of the universe

Incredibly small yet powerful particles called neutrinos could reveal how the universe works – and even why matter exists at all. © remotevfx.com, Shutterstock.com

Deep under the Mediterranean, scientists have recorded the highest-energy neutrino ever detected. Now they are working out what this elusive particle could reveal about the universe we live in. By Jonathan O’Callaghan Below the waves of the Mediterranean, Europe’s KM3NeT neutrino telescope is on a cosmic hunt. Towering strings of sensors stretch a kilometre down … Read more

Smarter decisions about real-world problems start with better data – and Earth observation can provide just that, thanks to European efforts to open up access to massive amounts of satellite data collected every day. By Gareth Willmer Imagine using space technology not just to explore the stars, but to stop a disease outbreak before it starts, … Read more

New telescope cuts through space noise in hunt for distant Earth-like worlds

EU-funded researchers are developing powerful new telescopes to help uncover Earth-like planets around distant stars and advance the search for extraterrestrial life. By Jonathan O’Callaghan Across the billions of galaxies and stars in the universe, only one place is known to host life – Earth. Yet the hope of finding other living worlds drives scientists … Read more
