Optical rotatum” is the term researchers coined to describe a newly discovered structure of light. Beams of light that can be shaped into corkscrew-like forms, known as optical vortices, are used ...

Astronomers have described the first measurements of plasma layers within an interstellar shock wave that surrounds a pulsar.

The once-dubbed "city-killer" asteroid 2024 YR4 has surprised scientists with its 'unusual' shape as it rapidly rotates ...

Space station astronaut Don Pettit has shared a clip showing streaks of light created by SpaceX's Starlink satellites.

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 ...

For the new study, researchers captured images of the space rock at different wavelengths of light. The team used 2024 YRY's pattern of light output over time, or lightcurve, to study the asteroid ...

The result is a continuous line of light that not only enhances safety but also anchors the architectural composition. In the cafetorium, a large multi-purpose space, patterns of D3 and D5 ...
