All Stories by Lisa Grossman

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. coronal mass ejections

    Merging magnetic blobs fuel the sun’s huge plasma eruptions

    Solar eruptions called coronal mass ejections grow from a series of smaller events, observations show.

  7. Kepler 1658b

    The first planet Kepler spotted has finally been confirmed 10 years later

    Astronomers had dismissed the first exoplanet candidate spotted by the Kepler space telescope as a false alarm.

  8. ‘Oumuamua

    3 explanations for ‘Oumuamua that aren’t alien spaceships

    Astronomers are coming up with some creative ideas to explain the weird behavior of the first known interstellar object.

  9. Hayabusa2
    Planetary Science

    Hayabusa2 just tried to collect asteroid dust for the first time

    The Japanese Hayabusa2 spacecraft touched down on asteroid Ryugu and attempted to gather a sample of its rock to bring back to Earth.

  10. black hole formation

    Colliding neutron stars shot a light-speed jet through space

    A stream of particles created in a neutron star crash, detected in 2017 using gravitational waves, could explain certain mysterious flashes of light.

  11. Neptune, Proteus and Hippocamp
    Planetary Science

    Neptune’s smallest moon may be a chip off another moon

    Neptune’s tiniest moon probably formed when a comet hit a larger moon.

  12. Mars ice caps
    Planetary Science

    Mars’ lake may need an underground volcano to exist

    If a lake under Martian ice is real, there must be a subsurface magma pool to keep conditions warm enough for water to remain liquid, scientists say.
