    A celestial loner might be the first known rogue black hole

    The object could be the first isolated stellar-mass black hole identified in the Milky Way — or it might be an unusually heavy neutron star.

    New Gaia data paint the most detailed picture yet of the Milky Way

    Gaia’s new data can tell us about galaxies the Milky Way has swallowed, the young solar system and asteroids that could hit Earth.

    Planetary Science

    Samples of the asteroid Ryugu are scientists’ purest pieces of the solar system

    Samples Hayabusa2 brought to Earth from asteroid Ryugu are far fresher than similar types of meteorites that scientists have found.

    A newfound, oddly slow pulsar shouldn’t emit radio waves — yet it does

    The highly magnetic neutron star rotates three times slower than the previous record holder, challenging the theorical understanding of these objects.

    50 years ago, the United States and Soviet Union joined forces for science

    In 1972, U.S. and Soviet leaders agreed to work together on science. Now, Russia’s war in Ukraine is straining that decades-long partnership.

    Ice at the moon’s poles might have come from ancient volcanoes

    Volcanic eruptions billions of years ago probably released enough water vapor to have deposited ice at the lunar poles, a study finds.

    High-energy neutrinos may come from black holes ripping apart stars

    Where extremely energetic neutrinos originate from is a mystery. A new study supports the idea that “tidal disruption events” are one source.
