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

Smalling makes case for defence

first_imgChris Smalling thinks he and Phil Jones have proved they deserve to be the long-term centre-half partnership for Manchester United. Their performance was one of the plus points in an otherwise forgetful stalemate. Smalling believes the friendly, which his former United team-mate Paul Scholes described as a “waste of time”, was just a one-off and he is confident of seeing England put on a better show when they play the final Euro 2016 qualifier of the season in Slovenia on Sunday. “It was like we had lost the game to be honest,” Smalling said, reflecting on the Ireland friendly. “We felt we could have done a lot better. “But at the end of the day we did keep our unbeaten run going and we kept a clean sheet so we’ll try and take some positives from it. “We probably needed the game in Dublin given the time off we’ve had. We needed to get it out of the way and make sure that we train really hard this week.” Smalling and the rest of his England team-mates will report for duty on Wednesday to begin preparations for the game in Ljubljana. If they win, England will move nine points clear at the top of Group E with four matches to go. “We know if we do the job on Sunday, qualification is near enough there,” Smalling said. “And then we can go into the summer relieved and happy whereas if we don’t win this game it is a long break so I don’t think there will be any problems with people getting up for it.” United were left with a considerable gap to fill at the heart of their defence last summer following the departures of Rio Ferdinand and Nemanja Vidic. but they ended the season with the fourth best defensive record in the Barclays Premier League. Goalkeeper David de Gea deserves a large chunk of the credit, but Smalling and Jones, who finished the campaign as Louis van Gaal’s first-choice centre-half pairing, merit praise too. Smalling admits he was facing a decisive season at United last term and he feels he passed it with flying colours. “Yes, I think it was (a make or break season),” the 25-year-old England centre-back said. “When you consider the outgoings at centre-back, players had to step in and luckily I’ve been one of those who has had a good run, especially in the second half of the season. “I think we (Jones and I) have proven we can fill the gap. It’s one where it just builds over time and we’ve had our chance this season and now it is all about building on that next season.” It does not look like Roy Hodgson has plans to install the pair as his preferred combination at centre-back any time soon, though. After naming him vice-captain, the England coach clearly has plans to give Gary Cahill a prominent role over the next year. The 67-year-old remains fiercely loyal to Phil Jagielka too and there are John Stones and Calum Chambers to consider too once they have come through the European Under-21 Championship. Hodgson went with the Smalling-Cahill combination on Sunday for England’s dull 0-0 draw against the Republic of Ireland. Press Associationlast_img read more

NSSM Points ‘Way Forward’ for Sports

first_imgThe Nigeria Society for Sports Management (NSSM) has identified areas that could enhance and sustain sports development in the country.A five-point communiqué signed by the NSSM President, Professor Muhammed Gambari, at the end of the body’s 2018 national conference held in Kano over the weekend, urged the Federal Government to urgently establish a channel for effective collaboration between various government parastatals in sports at  local, state and national levels with the NSSM towards involving positive management strategies through functional research process for effective policy formulation and implementation, even as it urged the government to closely monitor implementation of formulated policies with a view to achieving desired results.The communiqué stressed the need for government to support individuals with cognate experience to get appointed into key positions in the sports ministry, although this should be backed by what the NSSM called appropriate legislation.It also advocated effective collaboration between the government and private sector to ease the burden of funding on government, while also urging human capacity building to facilitate quality personnel through constant staff training in line with the best practices in other countries.Share this:FacebookRedditTwitterPrintPinterestEmailWhatsAppSkypeLinkedInTumblrPocketTelegramlast_img read more
