All Stories by Lisa Grossman

  1. galaxy M87

    The M87 black hole image showed the best way to measure black hole masses

    The first image of M87’s black hole suggests it is 6.5 billion times the mass of the sun — close to what was expected based on how stars move around it.

  2. meteor
    Planetary Science

    A 2014 meteor may have come from another solar system

    Scientists have identified a possible interstellar meteor, and think it could be one of millions that have visited Earth over the planet’s history.

  3. moon
    Planetary Science

    Meteor showers dig up water on the moon

    Meteorites release water from the moon’s soil, hinting that the moon has water buried all across its surface.

  4. supermassive black hole at M87

    The first picture of a black hole opens a new era of astrophysics

    Astronomers used a network of telescopes around the world to take a picture of the supermassive black hole in the galaxy M87.

  5. dust plume at impact site on Ryugu's surface
    Planetary Science

    Hayabusa2 has blasted the surface of asteroid Ryugu to make a crater

    Japan’s Hayabusa2 spacecraft shot a projectile at Ryugu. Next: collecting asteroid dust from the probable impact crater left behind.

  6. asteroid cross-section illustration
    Planetary Science

    Metal asteroids may have once had iron-spewing volcanoes

    Two groups of scientists introduce the idea of “ferrovolcanism,” or iron volcanoes, that could have occurred on metal asteroids like Psyche.

  7. Astronomy

    4 things we’ll learn from the first closeup image of a black hole

    Scientists are gearing up to release the first image of the black hole at the center of the galaxy. Here’s what they hope to find out.

  8. Saturn's rings
    Planetary Science

    Saturn’s rings paint some of its moons shades of blue and red

    Moons located among Saturn’s inner rings are different colors depending on their distance from the planet, suggesting they’re picking up ring debris.

  9. Kuiper Belt
    Planetary Science

    Kuiper Belt dust may be in our atmosphere (and NASA labs) right now

    Bits of space debris that collect in Earth’s atmosphere may come from as far as the cold, distant Kuiper Belt region beyond Neptune.

  10. Ryugu asteroid
    Planetary Science

    Ryugu is probably a chip off one of these two other asteroids

    Japan’s Hayabusa2 team has narrowed down the asteroid Ryugu’s origins based on its color.

  11. Bennu
    Planetary Science

    Surprising astronomers, Bennu spits plumes of dust into space

    Bennu spews dust from its rocky surface, which may be a new kind of asteroid activity.

  12. Ultima Thule
    Planetary Science

    Ultima Thule may be a frankenworld

    The first geologic map of Ultima Thule shows it might be made of many smaller rocks that clumped together under the force of their own gravity.
