This image shows the closest stellar system to the Sun, the bright double star Alpha Centauri AB and its distant and faint companion Proxima Centauri. In late 2016 ESO signed an agreement with the Breakthrough Initiatives to adapt the...
In this computer-generated image, a red oval marks the disk of our Milky Way galaxy and a red dot shows the location of the Sagittarius dwarf galaxy. The yellow circles represent stars that have been ripped from the Sagittarius...
This artist's impression shows a Milky Way type galaxy in the local Universe, surrounded by a much larger halo of blue, faint light, made of Lyman-alpha photons. While these photons were produced around hot, young stars in much more...
Recent images taken from Big Bear Solar Observatory of a massive section of the Sun's surface, about 23,000 miles square, showcase the advances in real-time clarity over vast distances presented by a groundbreaking new optics system.Credit: Image courtesy of...

This artist's conception portrays a collection of planet-mass objects that have been flung out of the galactic center at speeds of 20 million miles per hour (10,000 km/s). These cosmic "spitballs" formed from fragments of a star that was...
