  3. Astronomy

    Exoplanet spin measured for first time

    Astronomers measure the spin of a planet outside our solar system, and its days are short: just over eight hours.

  4. Astronomy

    Distant swirling galaxy dwarfed by violent star killer

    In a mosaic of images from a telescope in Chile, dark dust lanes and twisting tails betray a history of galactic collisions.

  5. Astronomy

    Astronomers have found a potentially habitable Earth-sized planet around a cool red star.

  7. Astronomy

    Early Mars couldn’t hold liquid water long

    Small rocks hit Mars 3.6 billion years ago, suggesting an early atmosphere too thin for liquid water to hang around very long.

  10. Planetary Science

    Icy rings found around tiny space rock

    Astronomers discover an icy ring around the planetoid Chariklo, held in place by unseen moons.

  11. Planetary Science
