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.

The first part of your question — how stellar objects reach millisecond spin periods — involves two concepts. First, the object needs to be small, since no material can move faster than the speed of ...

Astronomers have identified a vast, twisting chain of galaxies that appears to be rotating as a single structure, a kind of cosmic tornado that stretches across tens of millions of light years. If ...

Researchers have developed a real-time imaging system that can capture images of fast-spinning objects over long durations. Real-time monitoring of rotating parts such as the turbine blades used in ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Levitation might seem like a superpower out of science fiction ...

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 ...

Objects rotating at high speed are a feature of modern engineering in various fields, and online inspection of them is a critical challenge. A project at China's Jinan University has now developed a ...

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 ...
