From Artemis II to commercial satellites, laser communications are laying the foundation for a high-speed internet in space.

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such ...

A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures. The surprising ...

A citizen astronomer examining radio telescope data recently flagged something unusual: massive streams of radio emissions ...

Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes ...

The radio broadcast “air chain” is rapidly evolving from a linear, hardware-defined signal path into a flexible, software-driven ecosystem.

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed ...

These signals were first found by chance as telescopes scanned broad areas of the sky. Only about a dozen of these unusual ...

Scientists have suggested launching a giant 'airbag' into space to protect Earth from terrifying solar superstorms.

Wave energy has long been seen as a promising source of clean electricity. The ocean is always moving, and that motion ...

There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...
