[ Video 1 ] | [ Video 2 ] | [ Video 3 ] NASA said on Thursday that its scientists have discovered a surprisingly powerful millisecond pulsar that challenges existing theories. The international team of scientists used NASA's Fermi Gamma-ray Space Telescope to find that the object is the most luminous pulsar detected in the galaxy cluster to date, spinning at 11,000 rotations per minute. The researchers wrote in the November 3 issue of the journal Science that the pulsar is only 25...

WASHINGTON, July 2 /PRNewswire-USNewswire/ -- With NASA's Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. In two studies published in the July 2 edition of Science Express, international teams have analyzed gamma-rays from two dozen pulsars, including 16 discovered by Fermi. Fermi is the first spacecraft able to identify pulsars by their gamma-ray emission alone. (Logo:...

A new class of pulsars detected by NASA's Fermi Gamma-ray Space Telescope is solving the mystery of previously unidentified gamma-ray sources and helping scientists understand the mechanisms behind pulsar emissions.A study to be published by an international team of scientists in the July 2 edition of Science Express describes 16 pulsars discovered by Fermi based on their pulsed emissions of high-energy gamma rays. A pulsar is a rapidly spinning neutron star, the dense core left behind after...

GREENBELT, Md., Jan. 6 /PRNewswire-USNewswire/ -- NASA's Fermi Gamma-ray Space Telescope has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar cinders work. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) "We know of 1,800 pulsars, but until Fermi we saw only little wisps of energy from all but a handful of them," says Roger Romani of Stanford University, Calif....
