On 13 January, less than three weeks after being launched into space, the NUCLEON satellite experiment was switched on to collect its first cosmic-ray events.
Read article 'Planck reveals no evidence of new physics'
The release of the full mission data of ESA’s Planck spacecraft is a milestone for cosmology. Despite the high quality of the data – including, for the first time, polarization observation...
Read article 'HESS sees a powerful trio in a nearby galaxy'
High Energy Stereoscopic System (HESS) has discovered three extremely luminous gamma-ray sources in the Large Magellanic Cloud (LMC) – a dwarf galaxy orbiting the Milky Way about 170,000 li...
Read article 'Gamma-ray bursts are a real threat to life'
A new study confirms the potential hazard of nearby gamma-ray bursts (GRBs), and quantifies the probability of an event on Earth and more generally in the Milky Way and other galaxies. The authors fin...
Read article 'Ultra-luminous X-ray source is ‘just’ a pulsar'
Until now, ultra-luminous X-ray sources (ULXs) were thought to be black holes, because their high luminosity implied a mass exceeding by far the maximal mass of a neutron star. The most luminous of th...
