NASA-Discovered Symmetry In Black Hole Jets

Scientists at NASA have exposed a new stable that links various sizes of black holes. A black hole jet is the torrent of gamma radiation frequently emitted from the ‘event horizon’; the innermost rim and point of no go back, of a black hole. When gas gets sucked inside of the black hole, some of the substance becomes accelerated and races external as a pair of jets curving in opposite directions. Jets are seen in black holes of a lot of different sizes; from the modest-shaped, to the behemoth holes that power the centers of galaxies.

The group of scientists at NASA examined 54 gamma-ray bursts (GRBs) as of the minor black holes and compared them to 234 blazers and quasars, the galactic-scale corresponding of GRBs emitted from super enormous black holes. The NASA team found the same set of physical rules governed the size of these jets, apart from of the black hole size.

NASA's Response to Mine Disaster Remembered

One year ago on Oct. 14, 2010, the last of the 33 men trapped since Aug. 5 in a Chilean copper mine approximately 2,300 below the Earth's surface was pulled to safety with help from an unlikely source - NASA.It was a dire situation. While Chile's government agencies were devising rescue plans, they began seeking advice and information from other governments and organizations on how to assist the trapped miners. One of the organizations that responded to the call for assistance was NASA.

NASA quickly formed a team that included: Dr. Michael Duncan, Dr. J. D. Polk, both medical doctors, Dr. Albert W. Holland, a psychologist, and Clinton H. Cragg, an engineer. The team spent three days at the rescue site in Chile, assessing the parallels between the miner's plight and life in space.

Their advice ranged from warning rescuers that giving the starving men too much food too quickly could prove fatal to suggesting the miners wear sunglasses to protect their eyes when they surfaced after more than two months underground.The NASA team also provided suggested design requirements to the Chilean government for the innovative rescue capsule that ultimately saved the lives of the miners.
