    Red giant stars that eat planets might shine less brightly

    Some stars may shine less brightly after ingesting a planet. That finding, if confirmed, could have implications for calculating cosmic distances.

    A controversial X-ray glow didn’t show up in the Milky Way’s dark matter halo

    A new look at old data suggests that an odd X-ray glow that emanates from some galaxies cannot come from decaying dark matter.

    The star Betelgeuse might just be dusty, not about to explode

    A new study suggests that dust recently expelled by Betelgeuse is why the star dimmed suddenly in late 2019 before brightening again.
