    A record-breaking, oxygen-starved galaxy may be full of gigantic stars’ shrapnel

    The newly discovered galaxy may have once been home to stars more than 300 times as massive as the sun — a peek at conditions in the early universe.

    Uranium ‘snowflakes’ could set off thermonuclear explosions of dead stars

    Uranium crystals that settle in the cores of white dwarfs could trigger nuclear chain reactions that blow the dead stars apart, a new study suggests.

    Here’s why humans chose particular groups of stars as constellations

    Distances between stars, their brightnesses and patterns of human eye movement explain why particular sets of stars tend to be grouped together.

    The ‘USS Jellyfish’ emits strange radio waves from a distant galaxy cluster

    The unusual pattern of radio waves dubbed the USS Jellyfish tells a story of intergalactic gas meeting black hole by-products.

    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.
