ESO Telescope Images Stunning Central Region of Milky Way, Finds Ancient Star Burst

ESO's Very Large Telescope (VLT) has observed the central part of the Milky Way with spectacular resolution and uncovered new details about the history of star birth in our galaxy. Thanks to the ... read more

Exoplanets Can Be Made Less Habitable by Stars' Flares

Astronomers found that not all exoplanets in habitable zones will be able to maintain hospitable conditions for life. Exoplanets in close proximity to stars are subject to radiation bursts which can ... read more

Short-Lived Light Sources Discovered in the Sky

Roughly a hundred of very red, star-like sources that have appeared and vanished in short period of time have been discovered by a team of researchers when reviewing catalogue data, according to a ... read more

ALMA Spots Most Distant Dusty Galaxy Hidden in Plain Sight

Astronomers have spotted the light of a massive galaxy seen only 970 million years after the Big Bang. This galaxy, called MAMBO-9, is the most distant dusty star-forming galaxy that has ever been ... read more
