cosmology

The source of high-energy 'cosmic neutrinos' has eluded scientists for decades, that was until last September when such a particle struck a detector buried in ice at the South-Pole, research published in Science reveals. The event was coupled with the detection of a flaring 'blazar' by NASA's Fermi Gamma-Ray Telescope giving us a clue as to the origin of high-energy neutrinos. This discovery is not just significant for our knowledge of these particles however, it may help usher in a whole new age of astronomy.

Researchers find source of cosmic neutrinos ushering in a new era of ‘multi-messenger’ astronomy

Scientists observe consumption of a star by a supermassive black hole for the first time

The consumption of stars by supermassive black holes which lie at the centre of most galaxies is believed to be a fairly common event in the Universe, but astronomers have been unable to observe such proceedings unfold. That was until recently. It was revealed today that scientists at  Astrophysical Institute of Andalusia in Granada, Spain have used two specialised telescopes to observe the violent event in its full glory.
