    Astronomy

    An otherwise quiet galaxy in the early universe is spewing star stuff

    Seen as it was 700 million years after the Big Bang, the galaxy churns out a relatively paltry number of stars. And yet it’s heaving gas into space.

  6. illustration of ‘Oumuamua
    Space

    ‘Oumuamua may be a chip knocked off an icy, Pluto-like exoplanet

    If the first interstellar visitor were a shard of nitrogen ice, it would explain some of its unusual behavior when it passed through our solar system.

  9. illustration of a hot Jupiter orbiting a star
    Astronomy

    How ‘hot Jupiters’ may get their weirdly tight orbits

    Gravitational kicks from other planets and stars can send giant worlds into orbits that bring them close to their suns.

  12. star PDS 70 surrounded by dusty ring of debris, with bright dot inside ring that may be a moon forming
    Astronomy

    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.
