    Planetary Science

    This tiny, sizzling exoplanet could be made of molten iron

    A newly discovered exoplanet that whips around its star in less than eight hours is smaller than Earth, as dense as iron and hot enough to melt.

  2. image of the milky way galaxy

    Astronomers have found the Milky Way’s first known ‘feather’

    Named for the glacier that feeds India’s longest river, the Gangotri wave spans up to 13,000 light-years and bridges two of our galaxy’s spiral arms.

  3. image of Pluto's dark side
    Planetary Science

    Pluto’s dark side reveals clues to its atmosphere and frost cycles

    Light from Pluto’s moon Charon illuminated the dwarf planet’s farside offering clues about how nitrogen cycles between its surface and its atmosphere.

  4. image of the Whirlpool galaxy

    Astronomers may have spotted the first known exoplanet in another galaxy

    The spiral-shaped Whirlpool galaxy may be the host of the first planet spotted outside of the Milky Way.

  5. illustration of the Lucy spacecraft approaching an asteroid

    5 cool things to know about NASA’s Lucy mission to the Trojan asteroids

    NASA’s Lucy is the first spacecraft to head to the two giant clumps of space rocks that tag along in Jupiter’s orbit.

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

  11. 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.
