    Andromeda’s and the Milky Way’s black holes will collide. Here’s how it may play out

    Supermassive black holes in the Milky Way and Andromeda will engulf each other less than 17 million years after the galaxies merge, simulations show.

    Signs of a hidden Planet Nine in the solar system may not hold up

    Hints of a remote planet relied on clumped up orbits of bodies beyond Neptune. A new study suggests that clumping is an illusion.

    The number of Milky Way nova explosions per year has been pinned down

    Knowing how frequently these stellar eruptions occur will help determine their contribution to the galaxy’s chemical makeup.

    Two exoplanet families redefine what planetary systems can look like

    The TRAPPIST-1 and TOI-178 systems, both home to multiple bunched-up planets, have densities and orbits that defy expectations.

    The first magnetar flare detected from another galaxy was tracked to its home

    An outburst from the super magnetic remains of a star suggests similar eruptions are behind some of the most powerful explosions in the universe.
