For the first time the death of a comet near the Sun captured on video Facts

Scientists have managed to capture the destruction of the comet during the approach to the Sun in July 2011 and to make a short video of the event.

With special equipment, the scientists are able to observe the comet, flying every few years, close to the Sun. But until recently, these same scientists could not watch the last moments of the life of a comet before diving into the sun. July 6, 2011 NASA's Solar Dynamics Observatory were carried pictures of "evaporation" of comet C/2011 N3, reaching the solar atmosphere. Video made using these images. The comet is moving to the right of the Sun. The video is a rapid motion of the comet, because in reality the evaporation of comets in the searing heat of the sun occurred within 20 minutes. Movie was released on 20 January 2012 and is considered the first of its kind.

To see the comet in the video, you need to look very carefully. In real time the comet was moving at a speed of 645 kilometers per second.

As described in the journal "Science» (Science), the death of a comet observation opens new possibilities to assess the size and mass of the comet. It turned out that the comet about 45 to 90 meters in length with a mass comparable to the aircraft carrier. When injected into the solar atmosphere comet disappeared, highlighting million tons of electrically charged gas. Scientists believe that the "evaporation" of the comet with the solar wind have been thrown back into the solar system. Therefore, the approach of the solar wind with the Earth, scientists can identify the remains of a comet.

Analysis of diving comet in the solar atmosphere has allowed scientists to make several conclusions. First, the comet passed over 100,000 kilometers before evaporated. Second, in the last 20 minutes of her life, she broke into dozens of huge chunks of size from 10 to 45 meters in width. They were part of the coma of the comet (the gas and dust cloud surrounding the nucleus of the comet) width of 1200 kilometers, which was a tail length of 16 thousand kilometers. Thirdly, the motion of the light emitted by the comet tail is tarnished, it became brighter. Scientists believe that the reason for the change of pulse intensity in the sequential separation of pieces from the coma of the comet.

Photo of Comet C/2011 N3 during the approach to the Sun July 5 and 6, 2011, made the spacecraft SOHO. Bright sunlight is closed coronagraph. Circumsolar Creutz family comets like C/2011 N3, watch from the 1800s. It is believed that such comets are fragments of one large comet that split centuries ago.
