Bright Flash Detected in February Was a Black Hole Jet Pointed Straight at Earth

Illustration: Carl Knox – OzGrav, ARC Center of Excellence for Gravitational Wave Discovery, Swinburne University of Technology On February 11, astronomers saw a distant flash of light that seemed to come from a source as bright as a quadrillion suns. They alerted other scientists to the event, and several telescopes quickly pivoted to focus on …

Neutron Stars Are Basically Giant Cosmic Pralines, Astrophysicists Say

An illustration showing the internal workings of heavier (left) and lighter (right) neutron stars, imagined as pralines.Illustration: Peter Kiefer & Luciano Rezzola Astrophysicists modeling the insides of neutron stars have found that the extremely compact objects have different internal structures, depending on their mass. They suggest thinking of the stars as different types of chocolate …

Cosmic ‘Lighthouses’ That Beam Gamma Rays Could Reveal Gravitational Waves All Around Us

A team of astronomers have compiled 12.5 years of data from the Fermi Gammy-ray Space Telescope to form a gamma-ray pulsar timing array, a system of cosmic lighthouses that could help reveal ripples in spacetime. Since the first observation of gravitational waves in 2016, astronomers and astrophysicists have been trying to pin down the gravitational …
