Dark Matter Clues From The Center Of Our Galaxy
2014-04-03 13:57:46

[ Watch the Video: Fermi Data Hints At New Dark Matter Clues ] Francis Reddym, NASA Goddard Space Flight Center A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the...

[ Watch The Video: A Black Widow Pulsar Consumes its Mate ] Francis Reddy, NASA Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars. "The essential features of black widow and redback binaries are that...

First Gamma Ray Study Gravitational Lens
