Comet nucleus ISON completely disintegrated - RIA Novosti

MOSCOW, November 28 – RIA Novosti. The pictures of solar observatories visible signs of disintegration of the nucleus of Comet ISON, flies to the sun is not the kernel, and a cloud of debris that after perihelion passage will dissipate, and the comet will cease to exist , astronomers believe.

Previously, experts, based on radiosonde data of the comet in the millimeter range, has expressed the opinion that the comet nucleus collapsed. Now in favor of it as photometric data and the appearance of the comet in the pictures.

“The core of the comet … finally collapsed around noon in Moscow, and we continue to see a drop in its brightness. probably because the sun will leave trail of wreckage and already dust. Shining spectacle in the morning sky in December, do not wait, but Faint tail may appear “- told RIA Novosti supervisor of the observatory” Ka-Dar “Stanislav Korotkiy.On added that now on the original images from SOHO can be seen that the” head of a comet looks slabokontrastym blurred cloud without sharp boundaries – is a clear sign of nuclear fragmentation “.

on pictures with solar observatory “Stereo” it is clear that in place of the comet head remains only melting cloud. Some astronomers believe that comet evaporates completely, and after perihelion, the comet that was to be held at 22.45 MSK, has nothing emerges. “Yes, the kernel is completely disintegrated, leaving only the dust plume. Pictured (from SOHO) at 17.36 (GMT ) that all smeared “- told RIA Novosti astronomer Leonid Elenin of the Institute of Applied Mathematics RAS Keldysh. “I think it is still something to be still visible after perihelion,” – he added.

Previously, some scientists have suggested that Comet ISON will behave according to the scenario of Comet Lovejoy – it will pass perihelion, reaching maximum brightness, and then disintegrate.

Comet C/2012 S1 (ISON), which opened in September 2012, Russian astronomer Artem Novichonok and his counterpart from Belarus Vitaly Nevsky, boomed because scientists believed that this comet may be the brightest in this decade. However, its brightness grew not as fast as expected.
