Astronomers found an interstellar "tunnel" - a cosmic channel that connects our solar system to distant stars, according to a recent study.

The European Space Agency has quietly added a major piece to its global space communications network with the inauguration of a new deep space antenna.

China advances plans for dual solar system boundary missions China has published coordinated papers outlining dual missions to the solar system’s edge, suggesting the long-studied project is nearing formal approval.

Our Sun’s outer atmosphere, the corona, is millions of degrees hotter than it should be, and no one knows why.

Space-based solar power advances with microwave and laser transmission, orbital assembly, and cost reductions, aiming for 24/7 clean energy from orbit.

Scientists are working on a project that can transform solar power in space with the help of lightweight cadmium telluride (CdTe) solar cells on ultra-thin glass. The technology can revolutionize energy systems for satellites and space-based manufacturing.

Observing the aurora is one of the few hobbies where “going outside and staring into the dark” qualifies as sound planning. The magnetic environment that surrounds our planet has been disturbed to G4 (severe) geomagnetic storm levels,

When my colleagues and I send them out to explore our solar system, it's important for us to understand the 3D map of our space neighborhood.

What: A forward-looking SETI Live discussion examining the most significant space science missions, discoveries, and observational opportunities anticipated in 2026.

NASA’s Goddard Space Flight Center shared the images of comet 3I/ATLAS. It's possibly as big as Manhattan, likely older than our own solar system and it's traveling through space at speeds of up to 153,000 miles per hour. It's also only the third ...

Scientists at the European Space Agency used a laser to communicate with a spacecraft 165 million miles (265 million kilometers) away in deep space for the first time, marking a major step forward in their efforts to build optical communication systems for ...
