Solar FlaresAtmosphere checksNASA says no damage from solar flares and certainly no earth-ending destructionCBC News 13 Sun's magnetic flip: 5 facts and myths about solar activity Sun will soon reverse its magnetic field CBC News Posted: Nov 13, 2013 5:55 AM ET http://www.cbc.ca/news/technology/sun-s-magnetic-flip-5-facts-and-myths-about-solar-activity-1.2424369♥Tina Some have expressed concerns that a "killer solar flare" could destroy earth. But scientists say those fears are unfounded because the Earth's thick atmosphere stops radiation produced by a solar flare. "Most importantly, however, there simply isn’t enough energy in the sun to send a killer fireball 93 million miles to destroy Earth," NASA said in a past statement. "Even at their worst, the sun's flares are not physically capable of destroying Earth.

Still, other researchers, such as NASA’s Hathaway, point out that for an event that big, the statistics are too flimsy to measure. The uncertainty rests in the relatively brief span of time in which scientists have recorded a link between sunbursts and electromagnetic fluctuations on Earth, the first being Carrington’s observations in 1859. And even then, the world knew about it only because an emerging technology went haywire. Sparks shocked telegraph operators and set fire to their paper. Electric surges created enough juice in some telegraph lines that operators were able to communicate even after disconnecting their batteries. According to newspaper accounts, the Northern Lights could be viewed as far south as the Caribbean, the result of electrically charged particles from the sun entering Earth’s atmosphere.

A few of the more notable asteroids NASA has placed on the "cleared" list in the past year include such high profile space rocks as the asteroid Apophis, which will swing extremely close to Earth in 2029 and return in 2036. All told, astronomers have found 90 percent of the large asteroids whose orbits bring them close to our planet. Apophis was cleared of concern last week when it made a distant flyby of Earth, which allowed astronomers to make new observations that helped complete rule out an impact threat in 2036. Previous observations had already ruled out the 2029 flyby. [See Photos of Giant Asteroid Apophis] In the near-future, as in this year, there will be other asteroids giving the Earth a close shave, said Yeomans. On Feb. 15, the 164 foot (50 meters) asteroid 2012 DA14 will pass the Earth at a range of about 17,200 miles (27,680 kilometers), well inside the orbit of geosynchronous communications satellites that fly about 22,370 miles (36,000 km) above the planet. Asteroid 2012 DA14 also poses no threat of impacting Earth during the flyby GeneralAmateurs solve and we can move asteroidsKramer 15 Big Strides Made in Tracking Near-Earth Asteroids, NASA Scientist (Yeomans, head of NASA’s Near Earth Object program) Says by Miriam Kramer, Space.com Staff Writer | January 15, 2013 http://www.space.com/19263-asteroid-threat-earth-don-yeomans.html♥Tina From there, NASA researchers enlist the help of amateur astronomers for follow-up observations to determine the orbit of a newfound asteroid, paying particular attention to how close the orbit track comes to the Earth. "We observe where these objects are in the sky and project their orbits on years into the future," Yeomans said. If Yeomans and his team did see an asteroid headed for the planet, there are a few courses of action available to them. Landing a small probe on the asteroid to nudge it slightly off course could be one way, while other have suggested impacting the crater with a probe that would drastically change its orbit, he said.

Luckily, "being classified as a PHA does not mean that an asteroid will impact the Earth," says NASA's Jet Propulsion Laboratory in a statement accompanying the image. Though the objects won't be legitimate threats over the next hundred years, tracking them gives NASA more accurate predictions of their possible approaches and likelihood of impact in the future. Just this year, the large asteroid 1998 QE2 safely traveled past Earth, making for the closest approach the space rock and its moon will make to Earth for at least the next two centuries.

Don Yeomans, head of NASA's Near-Earth Object Program, told a crowd here at the American Museum of Natural History that it is the smaller asteroids, not giant space rocks, that are difficult to spot. "It’s unlikely that we'd miss a big one," said Yeomans, who has written a new book on near-Earth asteroids "Near Earth Objects: Finding Them Before They Find Us" (Princeton University Press 2013). “It’s the small ones that sneak up on us Directory: file -> view view -> Western Europe after wwii view -> Author study: paul fleischman view -> Qpa1 7ela study Guide view -> Arctic Oil/Gas Neg view -> November 1970 Approximately 150,000-500,000 deaths Bhola Cyclone Bangladesh view -> Grade Level: 6 Unit of Study: Caribbean glce view -> Citation: Duffield, Katy view -> Table of Contents Lesson # view -> Chinese Wind Energy Disad Download 2.62 Mb.
