It's the latest in a series of mysterious radio signals that may point to new types of dead stars. Astronomers are looking for more of these signals — and hoping ones they've discovered will reappear.

A newly discovered asteroid has shattered speed records, completing a full rotation in just 112 seconds, faster than any other asteroid larger than 500 meters ever observed. Named 2025 MN45, this ...

A newly discovered asteroid, 2025 MN45, has forced planetary scientists to redraw one of their neatest rules of thumb. Spinning once every 1.88 minutes despite being roughly 710 meters across, it ...

Interactions between a spinning object and soundwaves could help develop high-precision tools, such as tweezers that control the motion and position of submillimeter objects by manipulating acoustic ...

To demonstrate the system, the researchers showed that it could reconstruct real-time high-quality still images of a model jet engine rotating at about ∼2170 rpm (top images) and a CPU cooling fan ...
