    Pluto’s smaller moons pose mysteries

    Pluto and Charon might have been the stars of the New Horizons mission, but the dwarf planet’s four smaller moons have some surprises to share as well.

    With images of Kerberos transmitted from the spacecraft on October 20, the Pluto family portrait is complete. The tiny moons Nix, Hydra, Kerberos and Styx are no longer pinpricks of light but textured, misshapen balls of ice that look...

    Mission to Pluto: Live coverage

    The New Horizons spacecraft flew by Pluto at 7:49 a.m. EDT on July 14, 2015. Astronomy writer Christopher Crockett wrote several updates from mission control at the Johns Hopkins University Applied Physics Lab in Laurel, Md., from July 12-15, and reviewed some of the mission's major milestones from the last several months. Check our Mission to Pluto editor’s pick for the latest on New Horizons...

    Rendezvous with Pluto

    View timeline

    Tiny, far-flung Pluto is about to have a visitor — at least for a few hours.

    On July 14, NASA’s New Horizons spacecraft will reach the dwarf planet and try to learn all it can about Pluto and its five known moons. Then the probe will leave Pluto behind, vanishing into the frigid darkness beyond the planets.

    In its wake, New Horizons will introduce Earth to the...

    More problems with Hubble

    Two anomalies onboard the orbiting Hubble Space Telescope, which stopped transmitting data on September 27, caused engineers to suspend re-activation of Hubble’s science equipment. Engineers encountered problems following an intricate maneuver to circumvent a piece of failed hardware. Hubble is currently orbiting Earth in a dormant “safe mode” while the malfunctions are assessed.

    In an...

    In communicating science, Europe envies the U.S.

    On July 21, at the Euroscience Open Forum in Barcelona, members of the European astronomy community participated in a discussion about why their space program has failed to engage public interest in a manner comparable to programs in the United States.

    Organized by Dirk Lorenzen, a physicist turned journalist for German public radio, the session was titled “Reaching for the Stars:...

    Images from the Edge

    David Schiminovich stared at a gallery of spiral galaxies as though he had never seen anything like them before. Indeed, no one had. He sat downloading the newly collected images in a narrow room overlooking a cavernous space at the California Institute of Technology in Pasadena. In that space, the mirror for the Palomar Telescope—until the mid 1970s, the world's largest telescope—had been...

    Mining the Sky

    The next really big observatory won't sit on a mountaintop or out in the desert. Nor will it fly aboard a spacecraft.

    Astronomers seeking the best views of the heavens have traditionally trekked to such remote outposts as the top of an extinct volcano in Hawaii or a desert in northern Chile. When they have needed to observe, say, one patch of sky over a broad range...
