All Stories by Lisa Grossman

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Sloan Digital Sky Survey telescope

    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.

  6. 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.

  7. side-by-side comparison of images of a galaxy

    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.

  8. image of Martian surface from China’s Zhurong rover

    China’s first Mars rover has landed and is sending its first pictures

    The country just became the second nation, after the United States, to successfully land a rover on Mars. Its rover will search for subsurface ice.

  9. image of Milky Way

    The Milky Way may have grown up faster than astronomers suspected

    Most of the galaxy’s disk was in place before a merger 10 billion years ago with a dwarf galaxy called Gaia-Enceladus/Sausage, a new study suggests.

  10. Ingenuity helicopter on Mars
    Planetary Science

    NASA’s Ingenuity helicopter’s mission with Perseverance has been extended

    NASA’s Ingenuity helicopter has passed all its tests and is ready to support the Perseverance rover in looking for ancient Martian life.

  11. a person in a clean suit maneuvers a gold-colored cube
    Planetary Science

    NASA’s Perseverance rover split CO2 to make breathable air on Mars

    An oxygen-making experiment on Perseverance shows that astronauts will one day be able to make air to breathe and, better yet, rocket fuel.

  12. 'yellowballs' in Milky Way, circled

    Mysterious ‘yellowballs’ littering the Milky Way are clusters of newborn stars

    The first comprehensive analysis of the celestial specks indicates they are clusters of infant stars of various masses.
