An international scientific team recently published a new map of the ocean floor based on Earth’s gravity field, and it is a particularly useful tool. The maps were created through computer analysis and modeling of new satellite data from ESA’s CryoSat-2 and from the NASA-CNES Jason-1, as well as older data from missions flown in […]
Known simply as ‘Gravity’, this multi-mode interferometer combines light from several telescopes to enable observations simulating a single extremely large telescope. Applied to the European Southern Observatory’s Very Large Telescope array, ‘Gravity’ detected a binary star pair within the Trapezium Cluster during its first observing run. Credit: ESO/M.

NASA’s Dawn spacecraft captured this image of the 16-mile-wide (26 kilometers) Kupalo Crater on the dwarf planet Ceres on Dec. 21, 2015.Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA New up-close photos of Ceres show some of the dwarf planet’s many craters in sharp and intriguing detail. The images were captured last month by NASA’s Dawn spacecraft from a distance of […]
Last month, the private spaceflight company SpaceX achieved an amazing feat: launching a rocket into space, and then landing it back on Earth in a history-making moment. Not only that, SpaceX stuck the rocket landing at night , and did it live online to boot. The sheer joy of that epic rocket landing comes through […]
Dark matter has been making waves in science for years, but apparently it’s been making ripples in the Milky Way for even longer. New research reveals that dark matter may be responsible for creating waves observed at the outer edges of the galaxy. The ripples were created as a dwarf galaxy containing dark matter zoomed […]

A nebula by any other name — the Twin Jet Nebula, a fabulous cosmic butterfly with two lobes of jets, shooting gases at speeds more than a million kilometers per hour, was discovered by Rudolph Minkowski in 1947. Experts believe the unique shape may be created by a binary star system at its core, with […]
