than typical stars in our neighborhood, the LIGO team reports February 11 in the Astrophysical Journal Letters, http://cheapjordansstock.com . , cheap jordans for sale ? One possibility is that the stars formed early in the universe before heavy elements had a chance to accumulate. At the other extreme, cheap Authentic jordans , the stars could have formed more recently in a relatively nearby (or local) and pristine pocket such as a dwarf galaxy. “With one observation, it’s impossible to say if it’s on one side of the continuum or the other,” says Vicky Kalogera, a LIGO astrophysicist at Northwestern University in Evanston, Ill. The best estimates put the collision in a galaxy about 1.3 billion light-years away (give or take a few hundred million light-years) in the southern sky, cheap jordans , roughly in the direction of the Magellanic Clouds, cheap retro jordans , two satellites of the Milky Way. A third LIGO facility, cheap jordans free shipping , such as one proposed for India, will help narrow down precise positions of future detections. So would a simultaneous burst of electromagnetic radiation from the location of a collision. LIGO has agreements with telescopes around the world (and in space) to keep an eye out for any flashes of light that occur at the same time as a gravity wave detection. For LIGO’s debut, cheap jordans online , no observatories reported anything definitive. But the Fermi gamma-ray satellite did see something interesting, astrophysicist Valerie Connaughton and colleagues report online February 14 at arXiv.org. “We found a little blip that’s weaker than anything we’d normally look at,” says Connaughton, cheap wholesale jordans , of the Universities Space Research Association in Huntsville, Ala.
