The object carried a unique feature related to its light reflective capabilities, which set it apart from previous ...

A team of astronomers have presented the first polarimetric observations of interstellar comet 3I/ATLAS, finding that it has ...

Astronomers detect a fast radio burst from 10 billion years ago, FRB 20240304B, revealing clues about the early universe.

Fast radio bursts (FRBs) are a kind of energetic cosmic radio burst. Though their duration is usually at millisecond scale, their energy (estimated isotropically) reaches 10 ^36 ～10 ^41 erg, ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...
