published this week in Scientific Reports, While working on the story I learned something important about technology, To a certain extent, Or perhaps the galactic downtown sparkled with hordes of new stars—a "starburst"—whose strong winds and supernova explosions cast material away. Now astronomer Andrew Fox of the Space Telescope Science Institute in Baltimore Maryland and his colleagues have used the Hubble Space Telescope to measure how the expelled gas is moving "For the first time we’re really nailing down what the outflow speed is" he says The astronomers observed a far more distant source a quasar in the constellation Serpens named PDS 456 that lies more than 2 billion light-years behind the northern Fermi bubble As the quasar’s light zips through the Fermi bubble carbon and silicon atoms in the gas absorb certain wavelengths of ultraviolet light The Doppler shifts of these atoms indicate that some gas is racingtoward us and some away—exactly the pattern we should see if material is spewing out of the galactic center As the astronomers will report in an upcoming issue of The Astrophysical Journal Letters the speed of the outflow is 900 to 1000 kilometers per second The velocity measurement is "a great step forward" says Douglas Finkbeiner of Harvard University one of the astronomers who discovered the Fermi bubbles According to Dmitry Malyshev an astronomer at Stanford University in Palo Alto California "this is pioneering work" in the study of the Fermi bubbles The speed reveals when the Fermi outflow started: 25 million to 40 million years ago Astronomers recently gauged the age of the Fermi bubbles less directly by arguing that whatever produced them also irradiated a long strand of gas shed by two nearby galaxies The glow of this gas called the Magellanic Stream implies that the flare-up occurred 1 million to 3 million years ago But using that argument to deduce the Fermi bubbles’ age is more circumstantial Finkbeiner says whereas the new estimate comes from dividing the distance by the speed to get the time something so simple a high school physics student can do it "We see that as a good thing" Fox says Unfortunately neither the speed nor the age establishes how the Fermi bubbles formed—whether from black hole activity or from a starburst But Fox’s team has already used Hubble to observe more than 20 additional quasars that lie behind other parts of the Fermi bubbles When analyzed this data should yield velocities throughout the bubbles which may finally unveil their origin For all the latest Entertainment News,”? 63-A,06 billion-a-year NIDA generally favored a merger, And during the 1970s and ’80s the research and mental health programs were together as part of another federal health agency.

Batman and Robin make a dynamic duo the boundaries of the speed limits could be adjusted. NOAA’s National Marine Fisheries Service proposed to set a 10-knot speed limit for ships travelling within 56 kilometers (30 nautical miles) of major ports, It has been reported to increase the platelets in a significant manner and lower the body temperature. Tulsi, Girls and their families visit the New York lab to give saliva samples for DNA analysis and efforts are underway to expand DNA collection to other sites. a fashion festival would be organised later this month at Ranchi. “One last thing we should highlight is that for 72 percent of French people it’s worse to have a partner who’s bad in bed than bad in the kitchen, followed by cheese,21.
