All Stories by Lisa Grossman

  1. origami satellite james webb

    When James Webb launches, it will have a bigger to-do list than 1980s researchers suspected

    The James Webb Space Telescope has been in development for so long that space science has changed in the meantime.

  2. illustration of planets colliding

    Space rocks may have bounced off baby Earth, but slammed into Venus

    New simulations suggest a way to help explain dramatic differences between the sibling worlds.

  3. image of Mars and the Pleiades star cluster with crisscrossing streaks from Starlinks satellites

    Satellite swarms may outshine the night sky’s natural constellations

    Simulations suggest that satellite “mega-constellations” will be visible to the naked eye all night long in some locations.

  4. rocks on Mars with drilled holes from NASA's Perseverance rover
    Planetary Science

    NASA’s Perseverance rover snagged its first Martian rock samples

    Two tubes of stone drilled from a basalt rock nicknamed Rochette are the first from Mars slated to eventually return to Earth.

  5. illustration of a steamy ocean horizon

    New ideas on what makes a planet habitable could reshape the search for life

    New definitions of “habitable worlds” could include planets with global oceans under a steamy hydrogen atmosphere or exclude ones that started out habitable but lost all their water.

  6. image of pluto

    The definition of planet is still a sore point – especially among Pluto fans

    In the 15 years since Pluto lost its planet status, scientists have continued to use the definition that works for them.

  7. A photo of the Martian landscape with part of the Perseverance rover in the foreground
    Planetary Science

    See some of the most intriguing photos from NASA’s Perseverance rover so far

    Six months ago, Perseverance landed on the Red Planet. Here’s what the rover has been observing.

  8. illustration of a black hole

    Measuring a black hole’s mass isn’t easy. A new technique could change that

    The timing of flickers in the gas and dust in a black hole’s accretion disk correlates to its mass, a new study finds.

  9. telescope image of a star cluster, which is surrounded by a blue haze

    How do scientists calculate the age of a star?

    There are a few different methods to determine the age of a star, but none are perfect.

  10. image of stars in the constellation Carina
    Planetary Science

    A century of astronomy revealed Earth’s place in the universe

    The past century of astronomy has been a series of revolutions, each one kicking Earth a bit farther to the margins.

  11. a row of stars in the night sky, with the milky way in the background

    Any aliens orbiting these 2,000 stars could spot Earth crossing the sun

    Alien astronomers in those star systems could discover Earth the way we find exoplanets: by watching for a dip in starlight.

  12. four images of Betelgeuse before and during its Great Dimming

    Dust and a cold spell on Betelgeuse could explain why the giant star dimmed

    Scientists had two options to explain Betelgeuse’s weird behavior in late 2019. They chose both.
