15-06-25 In late 2013, when the neutron star at the heart of one of our galaxy's oddest supernovae gave off a massive burst of X-rays, the resulting echoes -- created when the X-rays bounced off clouds of dust in interstellar space -- yielded a surprising ne...
14-05-07 Neutron stars, the extraordinarily dense stellar bodies created when massive stars collapse, are known to host the strongest magnetic fields in the universe -- as much as a billion times more powerful than any human-made electromagnet. But some neut...
13-12-02 Until now, scientists were pretty sure they knew how the surface of a neutron star -- a super dense star that forms when a large star explodes and its core collapses into itself -- can heat itself up. However, research by a team of scientists led by...
12-03-12 A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere(范围,球体) no larger than a city. In October 2010, a neutron star near the center of our g...
11-06-30 Newton space observatory has watched a faint star flare up at X-ray wavelengths to almost 10 000 times its normal brightness. Astronomers believe the outburst was caused by the star trying to eat a giant clump of matter. The flare took place on a ne...
11-02-24 NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid(超流体) , a bizarre, friction(摩擦) -free state of matter, at the core of a neutron star. Superfluids created in laboratories on Earth exhibit remarkable...
