All Stories by Lisa Grossman

  1. Astronomy

    The sun is less magnetically active than similar stars, and we don’t know why

    Why our star seems so different from its stellar kin is a mystery.

  2. EHT black hole image
    Physics

    A year after the first black hole image, the EHT has been stymied by the coronavirus

    With this year’s observing run canceled due to the coronavirus, the Event Horizon Telescope team is analyzing data from 2017 and 2018.

    Red giant stars that eat planets might shine less brightly

    Some stars may shine less brightly after ingesting a planet. That finding, if confirmed, could have implications for calculating cosmic distances.

  4. Saturn’s northern aurora
    Space

    Saturn’s auroras may explain the planet’s weirdly hot upper atmosphere

    Data from NASA’s Cassini spacecraft could help solve Saturn’s mysterious “energy crisis.”

  5. quasar illustration

    Quasar winds with record energy levels were seen fleeing a distant galaxy

    The Hubble Space Telescope has seen the most energetic quasar winds yet, showing these active black holes can blow star-forming gas out of galaxies.

  6. Pluto
    Planetary Science

    If Pluto has a subsurface ocean, it may be old and deep

    New analyses of images from NASA’s New Horizons spacecraft suggest that Pluto may have had a sea beneath its icy shell for roughly 4.5 billion years.

  7. Milky Way dark matter glow illustration
    Space

    A controversial X-ray glow didn’t show up in the Milky Way’s dark matter halo

    A new look at old data suggests that an odd X-ray glow that emanates from some galaxies cannot come from decaying dark matter.

  8. Planetary Science

    The asteroid Ryugu has a texture like freeze-dried coffee

    Only about half of the asteroid Ryugu is rock; the rest is airy holes, a finding that could help reveal details of how the planets formed.

  9. Planetary Science

    Coronavirus and technical issues delay a Mars mission’s launch

    The joint European-Russian ExoMars rover’s launch was postponed from July to 2022 so technicians could resolve issues with the landing equipment.

  10. Astronomy

    The star Betelgeuse might just be dusty, not about to explode

    A new study suggests that dust recently expelled by Betelgeuse is why the star dimmed suddenly in late 2019 before brightening again.

  11. Planetary Science

    Some ‘superpuff’ exoplanets may actually be ringed worlds like Saturn

    “Superpuff” planets look fluffy and light. But for some of the worlds, the effect could instead be explained by large, rocky rings, a study suggests.

  12. Planetary Science

    Meet Perseverance, NASA’s newest Mars rover

    NASA’s next Mars rover will be called Perseverance.
