Researchers have demonstrated quantum entanglement on a small satellite orbiting Earth. The team developed a miniaturized device that produces pairs of photons that are inextricably linked, which could help launch a fast and secure quantum internet.

Turns out the Red Planet is a little more green than we thought. The ExoMars Trace Gas Orbiter (TGO) has detected a tinge of green in the atmosphere, making it the first time this aurora-like glow has been spotted around a planet other than Earth.

SpaceX has followed last week's historic launch by firing a further 60 high-speed internet satellites into orbit as part of its Starlink project, including one fitted out with an experimental sun visor designed to reduce the reflectivity.

Virgin Orbit has come up short on its first attempt to reach orbit today after the mission was terminated soon after ignition of its LauncherOne rocket, with the team now working through the data and gearing up for its next attempt.

A small asteroid came within a cosmic hairbreadth of the ring of communications satellites circling the Earth in geosynchronous orbit at an altitude of about 35,000 km this week, passing the nearest satellite at a distance of about 1,200 km.

A new paper has revealed that Greenland and the Antarctic have lost a staggering amount of mass from their ice sheets over the last 16 years thanks to climate change, and that the melting has contributed to sea level rise.

SpaceX has announced that it will mount a sun visor on each of its Starlink satellites and have them perform controlled maneuvers, to make them less visible to the public and astronomers making detailed observations of the night sky.

The Global Position System (GPS) has turned 25 years old. Operated by the US Space Force, the constellation of navigational satellites went fully operational on April 27, 1995, though US Space Command made the formal announcement in July of that year.

The Intelsat 901 has returned to service less than two months after is historic docking with Northrop Grumman's first Mission Extension Vehicle. Now in a new orbit, the 19-year-old communications satellite will continue to operate for five more years.

The United States Space Force (USSF) reports that Russia has launched a Direct Ascent Anti-Satellite (ASAT) missile. US Space Command detected and tracked the weapon capable of destroying a satellite in low Earth orbit (LEO) on April 15.

Virgin Orbit continues to edge closer to its objective of firing satellites into space form an airborne 747, this time completing an end-to-end launch rehearsal designed to put all of its systems through their paces.

Although a hole in the ozone layer might sound like a retro environmental issue, it’s still a problem today. While it's usually over Antarctica, scientists have now spotted the biggest ozone layer hole in at least 25 years forming over the Arctic.
