first_imgA new record holder has been found for biggest star: LBV 1806-20 in Sagittarius.  According to the NewsNotes entry on p. 20 of the April 2004 issue of Sky and Telescope, the star is up to 3 times hotter than the surface of our sun, and has a diameter 200 times as big.    Most interesting is the star’s mass, estimated to be “150 solar masses — perhaps more.  That ought to make stellar theorists sit up and take notice.  No star can survive with more than about 100 or 120 solar masses, according to well-established theory.”Theories, like Olympic records, are made to be broken.  Let facts be true, and every theory a liar.    The news item on the next page, “Getting to Know Our Stellar Neighbors,” reports results of a survey of all the stars within 10 parsecs (about 32.6 light-years) of our sun.  Surprisingly, small red dwarfs rule, nearly 12 times more numerous than stars like our sun.  This provides more evidence against the belief that Earth orbits an ordinary star.  Also, the habitable zone around a red dwarf is much narrower, lowering the probability life could exist around such a star.  The astronomer doing the survey, Todd Henry, believes the constraint is balanced by the sheer numbers of red dwarfs, but what is the chance an earthlike planet would be found in a circular orbit within such a narrow ring, when even around our sun the habitable zone represents a small fraction of the radius of our solar system?  One might almost suspect our location, at just the right distance around the right kind of star, was intelligently designed (see next headline).(Visited 7 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Sources suggest the panel is likely to ask for an extension of two months to complete its investigation.The scandal had hit the 2013 edition of the IPL, with Delhi Police arresting three Rajasthan Royals players – S Sreesanth, Ajit Chandila and Ankeet Chavan – in a midnight raid in Mumbai.Investigations into the scam later revealed the involvement of Gurunath Meiyappan, son-in-law of former Board of Control for Cricket in India chief N Srinivasan and small-time Bollywood actor Vindu Dara Singh.last_img read more

first_imgKANSAS CITY, Missouri — Jamaal Charles proved he is back to full speed for the Kansas City Chiefs, returning from injury to score three touchdowns Sept. 29th. Tom Brady is still stuck in neutral for New England, picked off twice as Kansas City routed the Patriots 41-14.Charles, who missed last week’s win in Miami with a sprained ankle, ran for 92 yards and a score. The Pro Bowl running back also caught two short touchdown passes from Alex Smith, who had 248 yards passing and three touchdowns in a sharp performance before a raucous crowd.The Chiefs (2-2) ended a four-game skid at Arrowhead Stadium dating to last season by handing the Patriots (2-2) their worst defeat since losing to San Diego 41-17 in 2005.Along with throwing two interceptions, one of which was returned for a touchdown, Brady was strip-sacked by Tamba Hali to step up a field goal. Brady finished 14 of 23 for 159 yards.The Chiefs forced the Patriots to air it out by stuffing Shane Vereen and Stevan Ridley. And when Brady dropped back, their front seven ran roughshod over their suspect offensive line.It hardly helped the Patriots’ offense that it was trying to operate on the same night Chiefs fans were trying to reclaim the record for loudest outdoor sports venue.The record was set in the first half, when Guinness World Records record a noise level of 142.2 decibels — breaking the mark of 137.6 that the Seattle Seahawks’ fans had set last season.The crowd included several members of the Kansas City Royals, who made the walk across the parking lot from Kauffman Stadium to watch the start of the game on the sidelines. The Royals will play their first postseason game since 1985 against the Oakland Athletics on Sept. 30th.Knile Davis finished with 107 yards rushing for Kansas City. Tight end Travis Kelce had eight catches for 93 yards and a score.Charles gave the Chiefs an early lead with his first-quarter touchdown plunge, and then he extended the lead with a 5-yard TD catch in the second quarter.Cairo Santos added a 22-yard field goal just before halftime for a 17-0 lead.The field goal came after the Chiefs were bailed out by a defensive penalty. They had been stopped short on a pass play with 8 seconds left, but the penalty gave them a second chance.Kansas City had 303 yards of first-half offense, the most against any team coached by Bill Belichick.Charles added his third touchdown of the game early in the second half, taking a short pass in the flat and stumbling into the end zone. He appeared to grab his hamstring on the way down and was met by trainers as he exited the field. After a brief trip to the locker room, Charles logged a few more carries before his night was done.By that point, the game was pretty much done, too.Brady threw a 44-yard touchdown pass in the third quarter to Brandon LaFell, who slipped the grasp of cornerback Marcus Cooper to reach the end zone. But he was picked off by Husain Abdullah later in the half, and Abdullah returned the interception 39 yards for a touchdown.With the game out of hand, the Patriots gave rookie quarterback Jimmy Garoppolo a chance to play. He threw a late touchdown pass to Rob Gronkowski to complete the scoring.___(DAVE SKRETTA, AP Sports Writer)TweetPinShare0 Shareslast_img read more
