Scientists previously discovered comet more than a “tail”, guess whose core material may be a breakup, and now NASA observation records show most of the core material Comet ISON has disintegrated.
According to foreign media reports, has been hailed as the “Century Comet” Comet ISON staging a miraculous celestial landscape in the inner solar system at or near the track of the process, the scientists had previously discovered the comet more than a “tail”, guess the core material may be disintegration, NASA observation records now show the comet ISON most core material has dissolved, the volume decreases in perigee hot temperatures and radiation, the comet ISON could not “get through” critical journey, and now the comet only some wreckage substances still in motion, the brightness becomes very dark, in a joint meeting of the American Geophysical Union on December 10, the observations of the comet was announced.
Comet ISON also known as C/2012 S1, which comes from the distant space outside the solar system, the formation’s probably very old, even dating back to the early formation of the solar system, Naval Research Laboratory in Washington, DC, scientist Carl Bateng Si is considered a class of comets “dirty snowballs”, comets outer solar system’s Oort Cloud is the birthplace of millions of years ago, the comet’s orbit by the interference of an event, it flew aboard the space inside the solar system, This is the first time a comet ISON into the space within the solar system. The comet was first discovered in September 2012, Russian researchers Vitaly Kwasniewski and other first discovered the comet at a distance of 585 million miles, and was named ISON.
Sungrazers into the inner solar orbit, will have to pass through the orbit of Mars, so NASA probes on Mars can be deployed first to start the investigation of the comet, MRO HiRISE instrument detectors carried in October 2013 observed that comet nucleus is about half a mile in diameter, nearly 0.8 kilometers, the equivalent of five or six terms of the volume of the football field.
Space Science Laboratory, University of London comet expert Geraint Jones believed that this study is very meaningful to tail, when the comet arrived at perigee, NASA utilized space solar observation platform to study comets, such as the Solar Dynamics Observatory, as in December 2013, near the comet’s perihelion blocked, core material appeared split, forming many small matter, it’s basically the end of the tour the solar system.
