Astronomers crack exploding star mystery TUCSON. Arir. (AP) Aided bv supercomputer calculations. astronomers arn finally solving the pu/iele of what causes supernovae. powerful exploding stars that create the elements that make life possible. Astronomers have been stymied for decades in explaining what makes \or\ large stars explode at the end of their life time. The process was simply too com plex for chalkboard formulae But new supercomputers, capable of running millions of calculations a set - ond, have enabled astronomers to create mathematical model* that explain the mi< ntMH endlong changes that ik air a* a star JO time* the sire of the tun suddenly goes supernova* In presentations on Monday to the national meeting of the Amerii an Astro nomical Association. teams of astronomers showed computer-driven graphics of the pro*.esse* happening inside a supernova*? With the computer calculations, the astronomers cranked in convection and two-dimensional action within the explo sion and found that filaments of cold gas it roamed bat k toward th«i star's tort*, became superheated and then exploded outward Alt within a fractional second Matter simultaneously streams toward and away from the t ore and such circula tion of material happens to be i rut tally important for the explosion." said Mart Iterant, an astrophysicist at the l.os National 1-abotatorv Supernovae originate from stars eight to 10 times the sire of the sun After shin ing for millions of years, the star's unclear fuel is exhausted and there is not enough outflowing heat to keep the star's mass suspended above the core.

Five peo ple were killed. Truckers issued warnings on their citizens hand radios that prevented more vehicles from plowing into the burning wreckage on Interstate 40, about 30 miles northwest of Little Roc k "When we got out. all we could hear was screaming and hollering." said John Oakes of Pearishurg. Va.,a passenger in a truck that missed the pileup "They were screaming bloody murder." Fight tractor-trailers and a minivan were involved in the accident, police said. The van wasn't found until nine hours after the 2 am. accident, in a heap of smoldering 10-wheel ors "We believe everyone is accounted for,” said Ted Gip son of the Office of Emergenc y Services in Conway Countv. "There is still a pair of small shoes over there that we're concerned about." The dead were identified as truckers Delbert Costa. 53, and Gregg Lawrence, 39, Fort Smith men riding in the same truc k; trucker William Lewm of Soon v. trucker Donald Otto Saleh, 31, of Woodsboro, Texas; and telephone compa ny employee Jeff Satterfield of Little Roi k Another trucker was treated ami released from a hospital. Nearly all identifying marks had been burned from (be trucks, making identification of the victims difficult Two of the trai tor-trailers were hauling cattle, and injured ani mals limped amid emergent v workers Two trucks were carrying hardware, including i nns of paint .that periodit ally exploded. Other trucks were carrying scrap iron, lumber and newsprint. "We were coming down the road and all of a sudden we ran into a wall of fog. I hit the left lane and hit the brakes," said truck driver Walt Bums of Dublin. Va Ills truck stopped in the median "It was clear The next thing you know — pow! zero visibility,” Gipson said Burns broadcast a warning to other truckers, then made a futile attempt to extinguish the flames with a fire extin guisher. "It was like taking a jat kknife to a machine-gun fight. There was just nothing we could do,” Burns said. National Weather Service forei asts had said that patch es of fog were possible along the Arkansas River Valiev overnight. Forecaster Greg Meffert said that conditions didn't warrant a warning of hazardous travel Do you fit the bill?
