    A gargantuan supernova remnant looks 40 times as big as the full moon

    New observations confirm that a cloud in the constellation Antlia really is a supernova remnant and the largest ever seen from Earth.

    Most of Mars’ missing water may lurk in its crust

    Computer simulations of the fate of Mars’ water may explain why the Red Planet turned into a desert, when so little of its water has escaped into space.

    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 first black hole ever discovered is more massive than previously thought

    New observations of Cygnus X-1 are leading astronomers to rethink what they know about stars that turn into black holes.

    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.

    Fossil mimics may be more common in ancient rocks than actual fossils

    Evidence of early life may be harder to preserve than pseudofossils — structures that form abiotically but resemble living remnants.

    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.
