I'm about to run out of credit <a href=" http://www.aaapp.org.au/purchase-rogaine-foam.pdf ">rogaine discount code 2010</a> Magnetic field lines, themselves, are indeed invisible, but they naturally force charged particles – the material, called plasma, which makes up the sun – to course along their length. Space telescopes can see that material appearing as bright lines looping and arcing through the sun's atmosphere, and so map out the presence of magnetic field lines. Looking at a series of images, Su saw two bundles of field lines move toward each other, meet briefly to form what appeared to be an "X" and then shoot apart with one set of lines and its attendant particles leaping into space and one set falling back down onto the sun.
