    NASA’s DART mission lofted a swarm of boulders into space

    Hubble telescope images of the asteroid Dimorphos reveal a halo of 37 dim, newfound objects — most likely boulders shaken loose from the surface.

    Centuries on, Newton’s gravitational constant still can’t be pinned down

    A new experiment could finally answer the question 'What is the strength of gravity?' But it's a hard test to do.

    Granite likely lurks beneath the moon’s surface

    Without plate tectonics or water, granite is hard to make. But a 50-kilometer-wide hunk sits beneath the moon’s surface, lunar orbiter data suggest.

    A rain of electrons causes Mercury’s X-ray auroras

    The first direct measurement of electrons raining down on Mercury suggests this particle precipitation causes most auroras in the solar system.

    Ryugu asteroid samples are sprinkled with stardust older than the solar system

    Slivers of the asteroid appear to be from the fringes of the solar system and could reveal bits of the history of the sun and its planets.

    Mass has different definitions. The moon’s orbit confirms two are equivalent

    Laser measurements of the moon’s orbit square with Newton’s third law of motion and Einstein’s theory of gravity.

    Coronal rain has been seen splashing on the sun

    New images of the solar corona, taken by the Solar Orbiter probe, reveal bright fireball effects and upwelling induced by falling plasma droplets.

    Neutrinos offer a new view of the Milky Way

    Physicists turned to AI to help map out the newfound origins of ghostly neutrino particles coming from deep in the Milky Way.

    A newfound gravitational wave ‘hum’ may be from the universe’s biggest black holes

    Scientists reported evidence for a new class of gravitational waves, likely created by merging supermassive black holes.

    200 years ago, the Milky Way’s central black hole briefly awoke

    The black hole is thought to be mostly quiet and dim. Now, glowing cosmic clouds have revealed the behemoth’s last flare.

    Julian Muñoz has a ‘ruler’ that could size up the early universe

    The measurement tool could lay out a distance scale for cosmic dawn —and offer clues to the nature of dark matter.
