    Vera Rubin’s work on dark matter led to a paradigm shift in cosmology

    ‘Bright Galaxies, Dark Matter, and Beyond’ tells the story of how astronomer Vera Rubin provided key evidence for the existence of dark matter.

    Measuring a black hole’s mass isn’t easy. A new technique could change that

    The timing of flickers in the gas and dust in a black hole’s accretion disk correlates to its mass, a new study finds.

    Physics

    A bounty of potential gravitational wave events hints at exciting possibilities

    Of about 1,200 possible events, most are probably false alarms, but some could be ripples in spacetime that are especially hard to spot.

    Physics

    Black holes born with magnetic fields quickly shed them

    New computer simulations show one way that black holes might discard their magnetic fields.

    A super-short gamma-ray burst defies astronomers’ expectations

    A faraway eruption of gamma rays that lasted for only a second had a surprising origin: the implosion of a massive star.

    The tiny dot in this image may be the first look at exomoons in the making

    New ALMA observations offer some of the strongest evidence yet that planets around other stars have moons.

    How 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.

    Souped-up supernovas may produce much of the universe’s heavy elements

    An old star that formed from an explosive event called a magnetorotational hypernova is revealing where elements like uranium and silver might be forged.

    A shadowy birthplace may explain Jupiter’s strange chemistry

    Dust that blocked sunlight caused the giant planet to form in a deep freeze, a new study suggests.

    Astronomy

    Scientists spotted an electron-capture supernova for the first time

    A 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.
