Lobes of unexpectedly hot gas speeding away from a black hole in our galaxy have been discovered with NASA ‘s Chandra X-ray Observatory. The high temperature and the distance of the lobes from the black hole indicate that violent collisions are occurring between clumps of gas expelled from the vicinity of the black hole. A key finding was evidence indicating rapidly moving hot iron atoms. “Just like a super-highway, it’s a dangerous world out there,” said Simone Migliari on the University of Amsterdam, lead author on a paper from a September 6, 2002 issue of Science magazine. “Blobs of gas are getting rear-ended at speeds in excess of a hundred million miles per hours!”
Researchers have found that a portion of anomalous cosmic rays — charged particles accelerated to enormous energies by the solar wind — results from interactions with dust grains from a belt of comet-sized objects near Pluto’s orbit. These objects make up what is known as the Kuiper Belt, a remnant of the formation of the solar system.
