The first X-ray portrait of comet 3I/ATLAS has turned a rare interstellar visitor into a powerful new probe of the space between the stars. By catching the comet in high-energy light, ESA’s XMM-Newton ...

After nearly a century of chasing a shadow, physicists are staring at a new signal that looks uncannily like the long‑sought fingerprint of dark matter. The claim is bold: for the first time, a ...

Here is a thought experiment for you: imagine shining a powerful laser at the moon, the beam cutting through space until it lands on its dusty grey surface. Now flick the laser so the spot of light ...

A laboratory setup shows yellowish and bluish light from two lamps shining on a metallic reactor. Deep-ultraviolet, infrared, and visible light shine on carbon dioxide and methane in a reactor, ...

Long before rockets and satellites reached space, the Crab Nebula stood out as a steady beacon of high-energy light. At its center sits a dense, rapidly spinning neutron star that turns every 33.8 ...
