  1. 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.

  2. illustration of a steamy ocean horizon
    Astronomy

    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.

  3. image of pluto
    Astronomy

    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.

  4. 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.

  5. illustration of a black hole
    Astronomy

    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.

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

    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.

  7. 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.

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

    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.

  9. four images of Betelgeuse before and during its Great Dimming
    Astronomy

    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.

  10. Sloan Digital Sky Survey telescope
    Astronomy

    An arc of galaxies 3 billion light-years long may challenge cosmology

    Dubbed “the Giant Arc,” the purported structure is much larger than expected in a cosmos where matter is thought to be evenly distributed.

  11. NASA's orbiter VERITAS
    Planetary Science

    NASA will be heading back to Venus for the first time in decades

    Two newly selected missions, VERITAS and DAVINCI+, will explore the history of the planet's water and habitability.

  12. side-by-side comparison of images of a galaxy
    Astronomy

    Some fast radio bursts come from the spiral arms of other galaxies

    Tracking five brief, bright blasts of cosmic radio waves to their origins suggests their sources form quickly in regions with lots of star formation.
