    Here’s another strike against Venus having copious lightning

    Past data and the Parker Solar Probe’s new discovery of weird whistler waves overturn the idea that Venus’ hellish atmosphere has a lot of lightning.

  2. Astronomy

    The black hole–powered jet in galaxy M87 is making stars explode

    Hubble Space Telescope data show a surprising number of nova blasts along the jet of high-speed gas coming from the galaxy M87.

    NASA’s first look at a sample from asteroid Bennu reveals life’s building blocks

    Scientists have begun to analyze roughly 250 grams of Bennu, which could offer insight into solar system formation and life’s origins on Earth.

  4. Planetary Science

    In a first, astronomers spot the afterglow of an exoplanet collision

    A surge of infrared light from a remote star might have been a glow cast by the vaporized leftovers of an impact between Neptune-sized worlds.

  5. Physics

    Vela’s exploded star is the highest-energy pulsar ever seen

    A spinning dead star about 1,000 light-years away, in the constellation Vela, raises questions about how pulsars can emit such extreme radiation.

  6. Cosmology

    New JWST images suggest our understanding of the cosmos is flawed

    JWST data don’t resolve a disagreement over how fast the universe is expanding, suggesting we might need strange new physics to fix the tension.

  7. Astronomy

    This ‘polar ring’ galaxy looks like an eye. Others might be hiding in plain sight

    New images of two galaxies reveal what look like rarely seen rings of hydrogen gas nearly perpendicular to the galaxies’ starry disks.

  8. Astronomy

    Astronomers call for renaming the Magellanic Clouds

    Explorer Ferdinand Magellan is not a fitting namesake for the pair of satellite galaxies of the Milky Way, a group of scientists argues.

  9. Space

    NASA’s OSIRIS-REx has returned bits of the asteroid Bennu to Earth

    Asteroid dirt from Bennu could help reveal clues about the material that came together to make the solar system — and possibly where life comes from.

    Clara Sousa-Silva seeks molecular signatures of life in alien atmospheres

    Quantum astrochemist Clara Sousa-Silva studies how molecules in space interact with light, offering clues to what distant objects are made of.

  12. Physics

    Scientists have two ways to spot gravitational waves. Here are some other ideas

    From lasers in space to falling atoms on Earth, researchers are cooking up ways to sense gravitational waves that current methods can’t detect.
