Watch the video "Chandra Captures Neutron Star In Action" redOrbit Staff & Wire Reports - Your Universe Online New video footage of the Vela pulsar, a neutron star located approximately 1,000 light-years from Earth, suggests that the pulsar could be slowly wobbling as it spins, NASA officials said on Monday. Formed following the collapse of a massive star, the Vela pulsar is approximately 12 miles in diameter and capable of making a complete rotation in under 90 milliseconds. The...

Image 2 - Slowpoke Pulsar Found Nestled In Young Supernova Remnant
2011-12-20 15:09:57

Astronomers have discovered a very slowly rotating X-ray pulsar still embedded in the remnant of the supernova that created it. This unusual object was detected on the outskirts of the Small Magellanic Cloud, a satellite galaxy of the Milky Way, using data from a number of telescopes, including ESA's XMM-Newton. A puzzling mismatch between the fairly young age of the supernova remnant and the slow rotation of the pulsar, which would normally indicate a much older object, raises interesting...

A spectacular new image shows how complex a star's afterlife can be. By studying the details of this image made from a long observation by NASA's Chandra X-ray Observatory, astronomers can better understand how some stars die and disperse elements like oxygen into the next generation of stars and planets. At a distance of about 20,000 light years, G292.0+1.8 is one of only three supernova remnants in the Milky Way known to contain large amounts of oxygen. The image shows a rapidly expanding,...

  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
