    Clouds in the Milky Way’s plasma bubbles came from the starry disk — and far beyond

    Gas clouds in the Fermi bubbles have a wide range of chemical compositions, suggesting some may have been ripped from other galaxies.

    A new look at the ‘mineral kingdom’ may transform how we search for life

    A new census of Earth’s crystal past hints that life may have begun earlier than expected, and could be a tool to look for water and life elsewhere.

    50 years ago, a new theory of Earth’s core began solidifying

    In 1972, scientists proposed that Earth’s core formed as the planet came together. Fifty years later, that theory is generally accepted, though many mysteries about the core remain.

    Six months in space leads to a decade’s worth of long-term bone loss

    Even after a year of recovery in Earth’s gravity, astronauts who’d been in space six months or more still had bone loss equal to a decade of aging.

    An otherwise quiet galaxy in the early universe is spewing star stuff

    Seen as it was 700 million years after the Big Bang, the galaxy churns out a relatively paltry number of stars. And yet it’s heaving gas into space.
