  1. Planetary Science

    Neptune gets 14th moon

    Images from Hubble Space Telescope reveal tiny, dark satellite orbiting blue-green gas giant.

  2. Physics

    A Piece of the Sun

    The Quest for Fusion Energy by Daniel Clery.

  3. Physics

    Perfect mirror debuts

    Material that reflects light without letting any escape could improve lasers.

  4. Astronomy

    The solar system has a tail

    Clover-shaped clumps of charged particles extend billions of kilometers in our wake.

  5. Space

    Interstellar chemistry makes use of quantum shortcut

    Reactions in the frigid cold of space are sped by a quirk of physics, researchers propose.

  6. Physics

    Particles defy gravity, float upstream

    Inspired by tea leaves’ reverse route into a kettle, physicists demonstrate that water’s surface tension allows unexpected movement.

  7. Quantum Physics

    Most precise clock

    It would take more than 50 billion years for a new atomic clock to gain or lose a second.

  8. Tech

    Twisted light transmits more data

    Spiral beams allow multiple information streams in one cable.

  9. Particle Physics

    First four-quark particle may have been spotted

    If confirmed, the tetraquark could shed light on how atomic nuclei are held together.

  10. Astronomy

    Hubble finds hints of a planet oddly far-flung from its star

    If confirmed, the dark gap in space debris will challenge astronomers' theories.

  11. Physics

    Echoes create an interior map app

    To record size and shape of a room, researchers use a speaker, five microphones and some math.

  12. Physics

    Simple invisibility cloaks hide toys, pets, people

    Using everyday materials, two research teams conceal ordinary objects by guiding light around them.
