Using ultra-fast laser pulses and special cameras, scientists have simulated an optical illusion that appears to defy Einstein's theory of special relativity. One consequence of special relativity is ...

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, first made over 60 years ago. When an object approaches the speed of light ...

Researchers demonstrated a new type of optical manipulation: using laser light to pull a macroscopic object. The technology has potential for applications in the continued explorations of Mars.

Holograms. Practically every sci-fi movie and TV show from the last 50 years has some version of this futuristic technology. A realistic 3D object composed of nothing more than light, usually hovering ...

The article details various types of deep-sky objects observable by amateur astronomers, including double stars, variable stars, open and globular star clusters, emission, planetary, and reflection ...

Astronomers have spotted a mysterious object in a distant star system that erratically emits dust that shrouds its star, obscuring its light by as much as 75 percent. The researchers behind the ...

Ziteng Wang found a needle in an astronomical haystack. Wang, a physics PhD student at the University of Sydney, was combing through data from Australia's ASKAP radio telescope in late 2020. His ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical illusion called the Terrell-Penrose effect. When you purchase through links on ...
