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.

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 ...

Back in July 2018, researchers at Purdue University created the world’s fastest-spinning object, which whipped around at 60 billion rpm – and now that seems like the teacup ride at Disneyland. The ...

In 1607, a comet appeared over Europe. This was Halley’s comet, later named after the astronomer who successfully predicted its reappearance and 75-year orbit in 1759. However, in 1607, it was just ...

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 ...

In the Optica Publishing Group journal Optics Letters, researchers presented their innovative imaging system based on a single-pixel detector. They demonstrate that it can capture images of an object ...
