151. Cosmic ray is high - energy particle ray coming from outer space.

152. During the 1970s, attempts were made to use cosmic ray spallation to produce deuterium. These attempts failed to produce deuterium, but did unexpectedly produce other light elements.

153. Team members have been gauging rock composition by measuring the x-rays and gamma-rays emitted by a surface bombarded by the sun's x-rays and by cosmic rays.

154. If two universes had collided, the researchers say, it would have left a circular pattern behind in the cosmic microwave background.

155. These cause spallation when a cosmic ray (e. g. a proton) impacts with matter, including other cosmic rays.

156. And Wilson and Penzias discovered the cosmic microwave background radiation, physical evidence for the Big Bang, while fiddling with an antenna designed to catch radio waves bouncing off satellites.

157. Fiery guitar - work embellishes the already hyperactive music, injecting ardent fury and cosmic demeanor.

158. About 1,000 light-years across, the twisted cosmic dust cloud apparently shaped like a parallelogram is likely the result of a smaller spiral galaxy falling into the giant Centaurus A.

159. Black holes are giant, cosmic vacuum cleaners that swallow up everything around them.

160. Therefore, the irreducible warp of the brane acts like a cosmological constant, which speeds up cosmic expansion.

161. There was tons of excitement in 1975 when a team announced it had detected a moving magnetic monopole in cosmic rays.

162. Such is the harrowing testimony of one of the closest eyewitnesses to what scientists call the Tunguska event, the largest impact of a cosmic body to occur on the earth during modern human history.

163. Of course, the shapes are cosmic dust clouds faintly visible in dimly reflected starlight.

164. Horus a falcon - headed god, who represented the greatest cosmic powers for ancient Egyptians.

165. Voyager 2: Low - Energy Charged Particles, Cosmic Ray Subsystem, Magnetometer, Plasma Wave Subsystem and Plasma Subsystem.

166. The inelastic cross-section and the distribution of the number of wounded nucleons in proton-Air collision have significant influence on the development of EAS caused by superhigh energy cosmic rays.

167. Developed and built at Goddard Space Flight Center in Greenbelt, Md., COBE precisely measured and mapped the oldest light in the universe -- the cosmic microwave background.

168. Such collisions would have left lasting marks in the cosmic microwave background (CMB) radiation, the diffuse light left over from the Big Bang that pervades the universe, the researchers say.

169. Isotopes of aluminum, beryllium, carbon ( carbon-14 ), chlorine, iodine and neon, are also formed through cosmic ray spallation.

170. Hot particles were too fleet-footed to settle into observed cosmic structures.

171. The recent progress on observation and theory of the cosmic microwave background radiation(CBR) is presented in this paper.

172. The glow of cosmic microwave background radiation, which is found throughout the universe,(sentencedict.com) is thought to be a tangible remnant of leftover light from the big bang.

173. Hurtling through a cosmic dust cloud a mere 400 light-years away, the lovely Pleiades or Seven Sisters star cluster is well-known for its striking blue reflection nebulae.

174. This has all the appearance of a cosmic free lunch.

175. A cloud chamber experiment is described, in which the angular distribution of secondary particles produced in nuclear interaction by high energy cosmic ray particles with paraffin has been studied.

176. In fact, we are only about 450 light-years from the front edge and 1,500 light-years from the back edge of this cosmic cloud of glowing hydrogen gas.

177. The reconstruction method of muon tracks in the L 3 Cosmic Ray Experiment has been studied.

178. Since massive stars live fast and die young, it is not so surprising that the cosmic Tarantula also lies near the site of the closest recent supernova.

179. Cosmic ray spallation produces some light elements such as lithium and boron. This process was discovered somewhat by accident during the 1970s.

180. If multiple universes exist, they may collide with each other and leave behind signs in the cosmic microwave background radiation, researchers say.
