- 			 Physics PhysicsA bounty of potential gravitational wave events hints at exciting possibilitiesOf about 1,200 possible events, most are probably false alarms, but some could be ripples in spacetime that are especially hard to spot. 
- 			 Physics PhysicsBlack holes born with magnetic fields quickly shed themNew computer simulations show one way that black holes might discard their magnetic fields. 
- 			 Astronomy AstronomyA super-short gamma-ray burst defies astronomers’ expectationsA faraway eruption of gamma rays that lasted for only a second had a surprising origin: the implosion of a massive star. 
- 			 Astronomy AstronomyThe tiny dot in this image may be the first look at exomoons in the makingNew ALMA observations offer some of the strongest evidence yet that planets around other stars have moons. 
- 			 Space SpaceHow do scientists calculate the age of a star?There are a few different methods to determine the age of a star, but none are perfect. By Lisa Grossman and Helen Thompson
- 			 Planetary Science Planetary ScienceA century of astronomy revealed Earth’s place in the universeThe past century of astronomy has been a series of revolutions, each one kicking Earth a bit farther to the margins. 
- 			 Astronomy AstronomyThe latest picture of a black hole captures Centaurus A’s massive jetsData from the Event Horizon Telescope reveal new details of jets spewing from the supermassive black hole at the center of the galaxy Centaurus A. 
- 			 Space SpaceSouped-up supernovas may produce much of the universe’s heavy elementsAn old star that formed from an explosive event called a magnetorotational hypernova is revealing where elements like uranium and silver might be forged. 
- 			 Astronomy AstronomyA shadowy birthplace may explain Jupiter’s strange chemistryDust that blocked sunlight caused the giant planet to form in a deep freeze, a new study suggests. By Ken Croswell
- 			 Astronomy AstronomyScientists spotted an electron-capture supernova for the first timeA flare that appeared in the sky in 2018 was an electron-capture supernova, a blast that can occur in stars too small to go off the usual way. 
- 			 Astronomy AstronomyThis moon-sized white dwarf is the smallest ever foundA newfound white dwarf is the smallest and perhaps the most massive known, and spins around once every seven minutes. 
- 			 Physics PhysicsGravitational waves reveal the first known mergers of a black hole and neutron starFor the first time, LIGO and Virgo have detected long-anticipated gravitational waves from a black hole merging with a neutron star.
