CAPE CANAVERAL, Fla. 鈥?The asteroid that got smacked by a NASA spacecraft is now being trailed by thousands of miles of debris stanley becher from the impact.Astronomers captured the scene millions of miles away with a telescope in Chile. Their remarkable observation two days after last months planetary defense test was recently released a National Science Foundation lab in Arizona.The image shows an expanding, comet-like tail more than 6,000 miles 10,000 kilometers long, consisting of dust and other material spewed from the impact crater.This plume is accelerating away from the harmless asteroid, in l stanley germany arge part, because of pressure on it from solar radiation, said Matthew Knight of the U.S. Naval Research Laboratory, who made the observation along with Lowell Observatorys Teddy Kareta using the Southern Astrophysical Research Telescope.Scientists expect the tail to get even longer and disperse even more, becoming so tenuous at one point that its undetectable. At that point, the material will be like any other dust floating around the solar system, Knight said in an email Tuesday.More observations are planned to determine how much and what kind of material was hurled from the 525-foot 160-meter Dimorphos, a moonlet of a larger asteroid.Launched nearly a year ago, NASAs Dart spacecraft was des stanley polska troyed in the head-on collision. The $325 million mission to deflect an asteroids orbit was intended as a dress rehearsal for the day a killer rock heads our way.

WASHINGTON 鈥?An extraordinary legal fight is brewing with major privacy implications for millions of cellphone users after a federal magistrate ordered Apple Inc. to help the FBI hack into an iPhone used by the gunman in the San Bernardino mass shootings.The clash brings to a head a long-simmering debate between technology companies insistent on protecting digital p kubki stanley rivacy and law enforcement agencies concerned about losing their ability to recover evidence or eavesdrop on the communications of terrorists or criminals.On Wednesday, the White House quickly disputed the contention by Apples chief executive officer, Tim Cook, that the Obama administration is seeking to force the software company to build a backdoor to bypass digital locks protecting consumer information on Apples popular iPhones.The early arguments set the stage for what will likely be a protracted poli stanley thermos cy and public relations fight in the courts, on Capitol Hill, on the Internet and elsewhere. They are not asking Apple to redesign its product or to create a new backdoor to one of their products, White House spokesman Josh Earnest said. Theyre simply asking for something that would have an impact on this one device. Within hours of the judges order Tuesday telling Apple to aid the FBI with special software in the case, Cook promised a court challenge. He said the software the FBI would need to unlock the gunmans work-issued iPhone 5C would be too dangerous to create and undeniably a backdoor.Cook compar stanley quencher ed |
