Astronomers have discovered evidence for an unusual kind of black hole born extremely early in the universe. They showed that a recently discovered unusual source of intense radiation is likely powered by a 'direct-collapse black hole', a type of object predicted by theorists more than a decade ago.
New research work may result in better simulations of large astrophysical events such as supernova explosions. This work also raises hopes of finding out more about how atomic nuclei behave in neutron stars.
To help detect suitable candidates, identify the range of atmospheric conditions on planets with water and shed light on how planetary magnetic fields originate and evolve, the HOTMOL project is devising new tools relying on spectro-polarimetry.
The GRAVITY instrument is now operating with the four 8.2-metre Unit Telescopes of ESO's Very Large Telescope, and even from early test results it is already clear that it will soon be producing world-class science.
Some 3.9 billion years ago in the heart of a distant galaxy, the intense tidal pull of a monster black hole shredded a star that passed too close. When X-rays produced in this event first reached Earth, they were detected by NASA's Swift satellite.
A new study presents one of the most complete models of matter in the universe and predicts hundreds of massive black hole mergers each year observable with the second generation of gravitational wave detectors.
Astronomers have discovered a vast cloud of high-energy particles called a wind nebula around a rare ultra-magnetic neutron star, or magnetar, for the first time. The find offers a unique window into the properties, environment and outburst history of magnetars, which are the strongest magnets in the universe.
A simulation of the powerful jets generated by supermassive black holes at the centres of the largest galaxies explains why some burst forth as bright beacons visible across the universe, while others fall apart and never pierce the halo of the galaxy.
