Could fast radio bursts be powering alien probes?

The search for extraterrestrial intelligence has looked for many different signs of alien life, from radio broadcasts to laser flashes, without success. However, newly published research suggests that mysterious phenomena ...

Ancient stardust sheds light on the first stars

A huge mass of glowing stardust in a galaxy seen shortly after the Universe's formation has been detected by a UCL-led team of astronomers, providing new insights into the birth and explosive deaths of the very first stars.

Hubble spotlights a celestial sidekick

This image was captured by the NASA/ESA Hubble Space Telescope's Advanced Camera for Surveys (ACS), a highly efficient wide-field camera covering the optical and near-infrared parts of the spectrum. While this lovely image ...
