    LIGO and Virgo detected a collision between a black hole and a mystery object

    The first evidence of an object more massive than any neutron star and more lightweight than any black hole has astronomers wondering what it is.

    Black hole plasma jets are shaped like bell-bottoms

    Jets of high-energy particles change from slightly curved sides to flared cones as they shoot away from galaxies, just like flare-legged pants.

    The Milky Way’s giant gas bubbles were seen in visible light for the first time

    Variation in the light’s wavelengths could help scientists map the velocity of the gas that makes up the towering structures known as Fermi bubbles.

    A Milky Way flash implicates magnetars as a source of fast radio bursts

    A bright radio burst seen from a magnetar in the Milky Way suggests that similar objects produce the mysterious fast radio bursts observed in other galaxies.

    Half the universe’s ordinary matter was missing — and may have been found

    Astronomers have used fast radio bursts as cosmic weigh stations to tease out where the universe’s “missing matter” resides.

    How tiny ‘dead’ galaxies get their groove back and make stars again

    Computer simulations explain how puny galaxies can sustain star formation: Gas falls into them and billions of years later begins to create new stars.
