    Here’s an easier new way to weigh a black hole

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

    Let’s learn about dark matter

    Dark matter is only detectable by the gravitational pull it exerts on visible objects, like stars and galaxies.

    Born in deep shadows? That could explain Jupiter’s strange makeup

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

    Spin in this Milky Way bar may show cosmic dark matter does exist

    A method akin to studying a tree’s rings reveals the timeline of a slowdown in those stars at the heart of our Milky Way galaxy.

    Huge arc of galaxies is surprising and puzzling cosmologists

    The arc appears to violate a cosmic rule that on such large scales, matter will be evenly distributed.
