The neutron star (illustration) at the center of the remains of the Cassiopeia A supernova may have a core filled with a strange frictionless fluid, new research suggests.
Point of impact: These infrared NASA images show particle debris in Jupiter’s atmosphere after an asteroid hit the planet on July 19, 2009. The impact and its after-effects can be seen as the bright spot on the lower left of an image taken on July 20 (left), and as the bright smudge on the lower left of an image taken on August 16 (right).
