A peculiar gamma-ray burst has been detected by ESA’s INTEGRAL gamma-ray mission. This sub-energetic burst makes the link between an earlier anomalous event and all other bursts detected so far....
Read article 'X-ray constraints on dark energy'
The existence and nature of dark energy has been probed using images of galaxy clusters obtained by NASA’s Chandra X-ray Observatory. These results are completely independent from the previous s...

Observations with the Very Large Telescope Interferometer (VLTI) at the ESO Paranal Observatory in Chile are for the first time providing a clear picture of the immediate surroundings of the black hol...
Read article 'Theory and experiment peer across the frontier'
The fourth conference in the "Beyond" series presented a clear overview of - and beyond - the current frontiers of particle physics, astrophysics and cosmology.
Read article 'VLT detects farthest known galaxy'
The discovery of a galaxy at a redshift of 10.0 smashes the record for the most distant object known in the universe. The detection of this very faint galaxy was made possible by combining the amplifi...

Given the apparent absence of antimatter at the cosmic scale, it might seem strange that a recent paper from the ASACUSA collaboration on quantum tunneling effects in collisions between antiprotonic h...
Read article 'Star ripped apart by giant black hole'
It has long been predicted that the very strong tidal forces of supermassive black holes at the centre of galaxies are able to disrupt stars venturing too close. Observational evidence for this phenom...
