    Check out the first-ever map of the solar corona’s magnetic field

    Solar physicists watched waves in the sun’s corona to map the whole corona’s magnetic field. Future observers could use the same technique to predict solar eruptions.

    In a first, astronomers spotted a space rock turning into a comet

    Scientists have caught a space rock in the act of shifting from a Kuiper Belt object to a comet. That process won’t be complete until 2063.

  8. Hyades star cluster
    Astronomy

    The star cluster closest to Earth is in its death throes

    Gaia spacecraft observations of stars’ motion within and fleeing the cluster suggest the 680-million-year-old Hyades has only 30 million years left.

    Astronomy

    This is the first picture of a sunlike star with multiple exoplanets

    A first family portrait reveals a weird cousin of the solar system: a star about the mass of the sun orbited — distantly — by two massive gas giants.

    Pinning down the sun’s birthplace just got more complicated

    Many astronomers think that the sun was born in a loose association of thousands of stars. A new study suggests there’s another possibility.

  11. small 'campfire' flare on the sun
    Astronomy

    The closest images of the sun ever taken reveal ‘campfire’ flares

    The first images from Solar Orbiter, a NASA-European Space Agency spacecraft, show tiny, never-before-seen flares across the sun’s surface.

    Space

    This is the most comprehensive X-ray map of the sky ever made

    A new X-ray map of the entire sky, using data from the eROSITA telescope’s first full scan, looks deeper into space than any other of its kind.
