A group of researchers from the Instituto de Astrofísica de Canarias (IAC) has clarified one of the mysteries of 2018 in the field of extragalactic astrophysics: the supposed […]

The bright spot in the centre of the image is a new planet forming. Valentin Christiaens et al./ ESO, Author provided When Italian astronomer Galileo Galilei first spotted four moons of Jupiter through a telescope, he realised that not everything goes around the Earth, as was the prevailing theory in 1610. The presumed origin of […]

Credit: Shutterstock We all know and love the Higgs boson — which to physicists’ chagrin has been mistakenly tagged in the media as the “God particle” — a subatomic particle first spotted in the Large Hadron Collider (LHC) back in 2012. That particle is a piece of a field that permeates all of space-time; […]

Gravitational waves, first detected in 2016, offer a new window on the universe, with the potential to tell us about everything from the time following the Big Bangto more recent events in galaxy centers. And while the billion-dollar Laser Interferometer Gravitational-Wave Observatory (LIGO) detector watches 24/7 for gravitational waves to pass through the […]

A visualisation of a binary neutron star merger. NASA’s Goddard Space Flight Center/CI Lab The hunt for gravitational waves is back on with the announcement overnight of the detection of signals from what’s thought to be the merger of two neutron stars, the incredibly dense remains of a collapsed star. The signals were actually picked […]
