On April 7, 2025, star HIP 16271 was occulted by Uranus. As a star, it is by no means famous. A yellow-white star in the ...

Using data from space telescopes and other instruments, astronomers, cosmologists, and astrophysicists are able to deduce and ...

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

Researchers have developed a new coronagraph—an optical device that blocks out light from a bright source—that could make it ...

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or ...
