Waspie_Dwarf Posted June 25, 2014 #1 Share Posted June 25, 2014 NASA's STEREO Maps Much Larger Solar Atmosphere Than Previously Observed Surrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around. Now, using NASA's Solar Terrestrial Relations Observatory, scientists have found that this atmosphere, called the corona, is even larger than thought, extending out some 5 million miles above the sun's surface -- the equivalent of 12 solar radii. This information has implications for NASA's upcoming Solar Probe Plus mission, due to launch in 2018 and go closer to the sun than any man-made technology ever has before.These STEREO observations provide the first direct measurements of the inner boundary of the heliosphere -- the giant bubble sparsely filled with solar particles that surrounds the sun and all the planets. Combined with measurements from Voyager 1 of the outer boundary of the heliosphere, we have now defined the extent of this entire local bubble. Read more...

shrooma Posted June 25, 2014 #3 Share Posted June 25, 2014 a soundwave 10 times the length of the earth?! christ, something with a wavelength that long must be bloody bowel-loosening! Link to comment Share on other sites More sharing options...
