    New Horizons recovers from overload, is on track for Pluto flyby

    The New Horizons spacecraft sent back three of the most detailed images of Pluto to date shortly before the probe entered a safe mode on July 4. The pictures, taken when New Horizons was about 13 million kilometers from the dwarf planet, show three different swaths of the icy surface as Pluto slowly rotated on...

    Beta Pictoris planet makes waves

    View the video

    A giant planet is making a splash in the belt of debris orbiting the young star Beta Pictoris. Spiral waves driven by the planet whip around the dusty disk, researchers report online June 24 at

    Like a pebble dropped into water, the planet sends out ripples through the dust and rock...

    Pluto may have spots the size of Missouri

    A chain of enigmatic dark spots mark the surface of Pluto in recent New Horizons images, taken when the spacecraft was about 22 million kilometers from the dwarf planet. Each splotch is about 500 kilometers across and covers roughly the same area as the state of Missouri.

    A loopy look at sunspots

    Tangled nests of magnetic fields burst from sunspots on the solar surface. The spots appear blue and yellow in this false color composite photograph, which was taken in October by NASA’s Solar Dynamics Observatory and released in May. The pale streaks trace magnetic field lines, which stretch up to 200,000 kilometers above the surface (black).

    In visible light, sunspots look like dark...

    In retirement, Nobelist takes up moon bouncing

    If the moon is up, there’s a good chance Joseph Taylor is on his ham radio, using a homemade antenna in his backyard to bounce signals off the moon’s pockmarked face. It’s a skill Taylor began cultivating in 2003, shortly before he retired from Princeton University, where he used radio waves to probe the secrets of pulsars, the spinning, magnetized neutron stars that emit bursts of radiation...

    Super-Earths are not a good place for plate tectonics

    Plate tectonics doesn’t rumple the surfaces of Earth’s supersized cousins, new research suggests.

    Simulating the extreme pressures inside giant exoplanets called super-Earths, researchers discovered that these planets probably have thick, stagnant outer shells and sluggish internal circulation. Those properties make the existence of fragmented jigsaw puzzles of sliding and shifting...

    Advice to a baby planet: Avoid black holes

    If you’re having a bad day, it could be worse: A black hole could be eating your planet. A dusty blob that loops around the heart of the Milky Way might be all that’s left of an infant world, researchers suggest June 18 in the Astrophysical Journal. The embryonic planet could have been kidnapped by the region’s...

    X-ray rings reveal neutron star’s distance

    A cosmic bull’s-eye is helping astronomers pinpoint the distance to a neutron star. Concentric rings of X-rays bouncing off interstellar dust indicate that the stellar remnant is about 31,000 light-years away in the constellation Circinus, researchers report in the June 20 Astrophysical Journal.

    The X-rays, seen...
