    A Milky Way flash implicates magnetars as a source of fast radio bursts

    A bright radio burst seen from a magnetar in the Milky Way suggests that similar objects produce the mysterious fast radio bursts observed in other galaxies.

    A weird cosmic flare called the ‘Cow’ now has company

    Scientists have now found three similar luminous, short-lived bursts of light, part of a class known as fast blue optical transients.

    Meteorites might be more likely to strike near the equator

    Meteorites from Antarctica have helped scientists assess the total number likely to hit Earth every year — and where they are most likely to fall.

    Half the universe’s ordinary matter was missing — and may have been found

    Astronomers have used fast radio bursts as cosmic weigh stations to tease out where the universe’s “missing matter” resides.

    A star shredded by a black hole may have spit out an extremely energetic neutrino

    A star’s fatal encounter with a black hole might have produced a neutrino with oomph.

    Stunning images of swirling gas and dust may show a planet forming

    Infrared images show a spiral of gas and dust around a star 520 light-years away. A smaller, tantalizing twist hints at where a planet is coalescing.

    The oldest disk galaxy yet found formed more than 12 billion years ago

    A spinning disk galaxy similar to the Milky Way formed just 1.5 billion years after the Big Bang, much earlier than astronomers thought was possible.

    Wiggling wheels could keep future rovers trucking in loose lunar soil

    A rover that wriggles through soil could climb hills on the moon or Mars that are too steep for a simple wheeled bot.

    Salty water might exist on Mars, but it’s probably too cold for life

    Salty liquids may last for several hours on the Red Planet but be too chilly for any known microorganisms from Earth to survive, simulations suggest.

    How tiny ‘dead’ galaxies get their groove back and make stars again

    Computer simulations explain how puny galaxies can sustain star formation: Gas falls into them and billions of years later begins to create new stars.
