Gcxv Chris Hemsworth Discusses What It Would Take For Him to Return as Thor
During the Fukushima nuclear disaster in 2011, fire trucks were desperately needed at the plant. It seemed like a straightforward request, except for one rather alarmin stanley france g development鈥攖he roads were blocked on the way into the facility owing to the tremendous damage caused by the tsunami. It was an understandable oversight, but perhaps something that couldve been foreseen. Indeed, disasters may be notoriously unpredictable, but that doesnt mean we should refrain from the attempt. Hence the importance of these tabletop exercises. By going through the motions of a disaster, we can foresee how a situation might actually unfold and evaluate various responses to an actual emergency. One of the most frightening disaster scenarios is an asteroid impact. As far as we can tell, no known asteroid poses a significant threat to our planet at any point in the near future, but that could quickly change should a potentially hazardous asteroid suddenly come into view. With that dark possibility in mind, NASAs Jet Propulsion Laboratorys Center for Near Earth Object Studies is currently leading a simulation of an impact scenario. Over the course of this five-day event, participants assume various roles, such as a national government, space agency, astronomer, civil protection authority, and so on. The group receives daily briefings about the unfolding situation, requiring them to think each situation through and respond accordingly.

Back in 2006, Spacewatch discovered an asteroid named 300163 2006 VW139 . Astronomers using the Pan-STARRS telescope detected some comet-like activity comin stanley usa g from the object in 2011, so it was also given a comet designation of 288P. Now, things have changed yet again. When the object made its closest approach to the Sun last year, a German-led team of scientists used the NASA/ESA Hubble Space Telescope to make observations, revealing not one but two asteroids stanley website . Which means its a binary system. The objects are almost the same size and mass, and theyre orbiting each other at a distance of 60 miles 100 km . But heres the thing鈥攖he asteroids each have a coma stanley borraccia a bright halo of ejected material and are together producing a single long tail of dust鈥攖he quintessential characteristics of a comet. Its now the first known binary asteroid thats also considered a main asteroid belt comet. These findings now appear in the science journal Nature. Hubbles latest observations shows theres a lot going on in this oddball binary. We detected strong indications for the sublimation [immediate conversion of a solid into a gas] of water ice due to the increased solar heating鈥攕imilar to how the tail of a comet is created, noted Jessica Agarwal, a scientist at the Max Planck Institute for Solar System Research whos studying the object, in a statement. 2006 VW139/288P has other weird features as well, namely an unusually wide 60-mile separation, strikingly similar weights and sizes, and a highl |
