Scientists detect biggest explosion since Big Bang

first_imgBut new telescope data from Australia’sMurchison Widefield Array and India’s Giant Metrewave Radio Telescope seem toconfirm it. And that meant any black hole explosionwould have to have been unimaginably prodigious. The huge release of energy is thought tohave emanated from a supermassive black hole some 390 million light years fromEarth. Scientists at first doubted theirexplanation however, because the cavity was so big; you could fit 15 of our ownMilky Way galaxies in a row into the hole. The eruption is said to have left agiant dent in the Ophiuchus galaxy cluster. They had long thought there wassomething strange about Ophiuchus galaxy cluster, which is a giant aggregationcontaining thousands of individual galaxies intermingled with hot gas and darkmatter. X-ray telescopes had spied a curious curved edge to it. SCIENTISTS have detected evidence for acolossal explosion in space – five times bigger than anything observed before. center_img Black holes are famous for gorging oninfalling matter, but they will also expel prodigious amounts of material andenergy in the form of jets. “In some ways, this blast is similar tohow the eruption of Mount St Helens (volcano) in 1980 ripped off the top of themountain,” said Simona Giacintucci of the Naval Research Laboratory inWashington, DC, and lead author of the study. (BBC) The speculation was that this might bethe wall of a cavity that had been sculpted in its gas by emissions from acentral black hole. Researchers reported their findings inThe Astrophysical Journal. Images of the Ophiuchus galaxy cluster appear to confirm the explosion. CHANDRA X-RAY OBSERVATORY last_img read more

Lawson hauls home Sprint series checkers from Shenandoah

first_imgBy Jim HainesSHENANDOAH, Va. (May 3) – Long haul trucker Brian Lawson knows about hauling fast freight and showing up on time and Saturday night he showed up at the finish line on time and first in the Vir­ginia Sprint Series feature at Shenandoah Speedway.The third different winner in as many IMCA Eagle Motorsports RaceSaver Sprint Car tour events this season, Lawson led the last 10 circuits.Charlie Ware and Chris Ware brought the field to green and Chris Ware led the first lap before Anthony Linkenhoker took over and began making good time. Laps on the pavement clicked off quickly.Tony Harris broke a logjam at the front and got by for the lead. Lawson was right there with them, got around Linkenhoker a couple laps later and was challenging the leader right away.With 10 laps to go, Lawson got around Tony Harris as Jerald Harris, French Grimes and Tom Humphries tried to stay in contention. Lawson stayed in front, Jerald got by to second and Humphries made his move to third with the white flag waving.No one would get by Lawson, however, as he as flashed under the waving checkered flag first. The next race for the series will be Saturday, May 24 back at Shenandoah as the race posted for May 17th at Fort Mountain Raceway in Bassett, Va., has been postponed. Feature results – 1. Brian Lawson; 2. Jerald Harris; 3. Tom Humphries; 4. Tony Harris; 5. French Grimes; 6. Anthony Linkenhoker; 7. Chris Ware; 8. Carl Simmons; 9. Ron Moyers; 10. Charlie Ware.last_img read more
