When scientists discovered two great swaths of radiation encircling Earth in the 1950s, it spawned over-the-top fears about "killer electrons" and space radiation effects on Earthlings. The fears were soon quieted: the radiation doesn't reach Earth, though it can affect satellites and humans moving through the belts. Nevertheless, many mysteries about the belts – now

NASA’s Research and Technology Studies (RATS) team will conduct its 2012 testing events in two phases. The first phase is further separated into two, three-day parts, conducted at Johnson Space Center’s (JSC) Building 9. The first part of phase 1 took place Dec. 13-15, 2011; the second part of phase 1 began Jan. 18, 2012, and will also last three days. This phase wi

NASA's most advanced mobile robotic laboratory, which will examine one of the most intriguing areas on Mars, is in final preparations for a launch from Florida's Space Coast at 10:25 a.m. EST (7:25 a.m. PST) on Nov. 25. The Mars Science Laboratory mission will carry Curiosity, a rover with more scientific capability than any ever sent to another planet. The rover is

An instrument on NASA's Mars rover Curiosity can check for any water that might be bound into shallow underground minerals along the rover's path. "If we conclude that there is something unusual in the subsurface at a particular spot, we could suggest more analysis of the spot using the capabilities of other instruments," said this instrument's principal investigator

The distorted shapes in the cluster are distant galaxies from which the light is bent by the gravitational pull of an invisible material called dark matter within the cluster of galaxies. This cluster is an early target in a survey that will allow astronomers to construct the most detailed dark matter maps of more galaxy clusters than ever before. These maps are bei

A fleet of spacecraft including NASA's Hubble Space Telescope has uncovered unprecedented details in the surroundings of a supermassive black hole. Observations reveal huge bullets of gas being driven away from the gravitational monster and a corona of very hot gas hovering above the disk of matter that is falling into the black hole.
