All Stories by McKenzie Prillaman

  1. Planetary Science

    Seismic waves suggest Mars has a solid heart

    NASA’s InSight lander listened to Marsquakes for four years. The tremors revealed that Mars may have a solid inner core.

  2. Astronomy

    Astronomers detect the brightest ever fast radio burst

    The fast radio burst came from 130 million light-years away. That proximity allowed an in-depth search for what produced the mysterious signal.

  3. Planetary Science

    A Mars rock analysis tool proved its mettle on a chance find from Arizona

    On Mars, the Perseverance rover found a spotted rock that could bear signs of ancient life. On Earth, a researcher used a lookalike for a dry run.

  4. Astronomy

    A newborn planet munches on gas and dust surrounding its host star

    In a first, astronomers imaged a baby planet within a gap in the disk of material around a star, confirming predictions about how rings form.

  5. Planetary Science

    NASA’s Webb telescope spotted a new moon orbiting Uranus

    Like Uranus's other 28 moons, the newfound object spotted by JWST will be named after a William Shakespeare or Alexander Pope character.

  6. Astronomy

    A dying star revealed its heart 

    Before exploding, a star shed most of its layers, giving a glimpse at a massive star’s deep interior. The event may represent a new kind of supernova.

  7. Astronomy

    The oldest known black hole formed more than 13.3 billion years ago

    The Webb telescope found that a far-off little red dot is the oldest known black hole, shrouded by gas that could help explain the ruby color.

  8. Planetary Science

    Cosmic rays could, in theory, sustain life on other worlds

    The hypothesis could extend the search for extraterrestrial life to include frigid planets with thin atmospheres and underground water.

  9. Planetary Science

    A giant planet may orbit our closest sunlike neighbor

    Alpha Centauri A, four light-years from Earth, may host a gas giant. If confirmed, no Earthlike planets orbit in the star’s habitable zone.

  10. Astronomy

    Seven superclouds sit just beyond the solar system

    The superclouds probably produce star-forming clouds of gas, since most nearby stellar nurseries are located within the giants.

  11. Astronomy

    The Webb space telescope spies its first black holes snacking on stars

    These star-shredding black holes sit within dusty galaxies that block many telescopes’ views. That’s not an issue for JWST.

  12. Astronomy

    Two colliding galaxies may have birthed this black hole

    An infinity symbol–shaped galaxy hosts an active supermassive black hole. The growing giant may have come from the aftermath of a galactic smashup.
