NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles.
The pulsar, a type of neutron star, is known as IGR J11014-6103. IGR J11014-6103's peculiar behavior can likely be traced back to its birth in the collapse and subsequent explosion of a massive star....

ew results from NASA's MABEL campaign demonstrated that a photon-counting technique will allow researchers to track the melt or growth of Earth’s frozen regions.
When a high-altitude aircraft flew over the icy Arctic Ocean and the snow-covered terrain of Greenland in April 2012, it was the first polar test of a new laser-based technology to measure the height of Earth from space....

Between November 9–11, 2013, a large iceberg separated from the calving front of Antarctica’s Pine Island Glacier. Scientists first detected a rift in the glacier in October 2011. By July 2013, infrared and radar images showed that the crack...

NASA’s Aqua satellite captured this image of Cyclone 04B (Helen) on November 21, 2013. The cyclone was weakening as it moved northwest and was expected to make landfall in the state of Andhra Pradesh as a tropical storm or category 1 cyclone overnight...
