For the third time in two years, physicists have detected ripples in the fabric of spacetime, called gravitational waves, that Albert Einstein predicted the existence of more than 100 years ago with his theory of general relativity. “Einstein continues to rock, in the sense that we keep pushing the boundaries of his theory,” Vicky Kalogera, an astrophysicist at Northwestern

Summer soon arrives, and the big planets Jupiter and Saturn will entertain evening onlookers, Venus will distract morning dog walkers and Mars starts a season-long hiatus. Catch a fattening, waxing moon as it approaches the bright Jupiter (-2.2 magnitude) in the southern sky on the evening of June 2 and then scooting past the planet June 3. Our lunar neighbour sails over the star Spica on

Just when we thought we had Jupiter all figured out, NASA’s Juno spacecraft reveals new results that challenge almost every assumption we’ve made about the gas giant. The first, said Juno’s principal investigator said Juno’s principal investigator from Juno’s initial two flybys back in August 2016 describe giant cyclones, a super powerful magnetic field, and weird

For the first time, scientists have detected evidence of a magnetic field that’s associated with the vast intergalactic ‘bridge’ that links our two nearest galactic neighbours. Known as the Magellanic Bridge, the bridge is a huge stream of neutral gas that stretches some 75,000 light-years between our two neighbouring galaxies, the Large and Small Magellanic

Astronomers have found a giant exoplanet larger than Jupiter, but with extremely low mass – a composition that gives this mysterious ‘puffy planet’ a density very similar to styrofoam. The team who found KELT-11b, which orbits a star located about 320 light-years from Earth, says this “extraordinarily inflated” world is the third-lowest density planet with a

An experimental US Air Force space plane called the X-37B Orbital Test Vehicle (OTV) has landed after a record-breaking 718 days in orbit, but with military officials keeping tight-lipped about the specific details of the operation, we’re no closer to understanding the objectives of its secretive mission. X-37B OTV-4 touched down at NASA’s Kennedy Space Centre
