Heart of the Crab Pulsar Probed — First Direct Look Into the Core of a Neutron Star
Image Credit: NASA/JPL-Caltech/R. Gehrz (University of Minnesota) New information about the heart of one of the most famous objects in the sky -- the Crab Pulsar in the Crab Nebula -- has been revealed by an international team of scientists searching for gravitational waves. The team's achievement also is the first direct look into the interior of a neutron star.
NASA's Swift Satellite Catches First "Normal" Supernova in the Act of Exploding
Seemingly out of nowhere, Supernova 2008D burst onto the scene on January 9, 2008, as seen in ultraviolet images (upper right) and X-ray images (beneath) taken by NASA's Swift satellite, giving scientists the unique opportunity to witness the birth of a supernova. CREDIT: NASA Swift team.
