Scientists identify 14 stars that could be made of antimatter
... would be much less gas and dust in interstellar space to accrete onto any potential antistars. Without a strong gamma-ray signature showcasing their whereabouts, these far-out antistars would easily evade detection. As tantalising as antistars are...

All of the starlight ever produced calculated by scientists
... of the fog to be measured not just at a given place but also at a given time in the history of the Universe. "Gamma-ray photons traveling through a fog of starlight have a large probability of being absorbed," said Ajello. "By measuring how many...

First detected neutron star merger reveals more than gravitational waves
... merger of binary neutron stars, although not everyone agreed on this theory. For GW170817, the gamma-ray burst was detected in gamma-rays, X-rays, optical light and infrared light, thus spanning a large portion of the electromagnetic spectrum. The...

Neutrino discovery helps resolve a century-old riddle
... follow the neutrinos lead to zero in on the same object. However, before that happens the joint neutrino/gamma-ray detection must be thoroughly scrutinised to be nothing short of infallible. With a roughly one in 740 probability that the neutrino...
