Fast radio bursts have stumped astronomers since the first one was reported in 2007 (, cheap jordans SN: 8/9/14, p. 22). Since then, http://cheapjordansstock.com , 17 more bursts have been detected by several radio telescopes around the world. In nearly every case, the outburst lasted just a few milliseconds and was never seen again. Only one, first detected at the Arecibo Observatory in Puerto Rico in 2012, has been seen multiple times (SN Online: 12/21/16). Most radio telescopes can provide only a fuzzy idea of where on the sky a burst comes from. But the repetitive nature of this burst, dubbed FRB 121102, cheap real jordans , gave astronomers a heads up of where to point the Very Large Array, a network of radio dishes near Socorro, N.M., cheap jordans for sale , which could provide a sharper image. “We have imaged the burst itself with the VLA and pinpointed where it is on the sky, cheap retro jordans ,” said Shami Chatterjee, cheap jordans online , an astrophysicist at Cornell University. Over the span of six months, cheap wholesale jordans , the VLA detected nine outbursts coming from the same direction as previous repetitions. A persistent glow of radio waves also comes from the same spot. Further observations with the Gemini telescope in Hawaii revealed that the radio outbursts coincide with a faint galaxy. By measuring how much the expansion of the universe has stretched the light coming from the galaxy, the researchers were able to measure the distance to the source of the burst.
