According vz.ru, the second time in a short period of time, scientists have recorded on the Sun NASA rare phenomenon — a powerful coronal mass ejection and the almost simultaneous collision of a comet with a star.
This coincidence of very different events happened on the night of 10 to 11 May, and again in the night from 20 to 21 May. This is evidenced by data reported to the Earth from space observatory SOHO and apparatus STEREO.
The speed of the ejected hot plasma of the solar corona (the flow of protons, electrons and heavy elements) can exceed 1.6 million miles per hour, and the weight of up to 10 billion tons.
"Shortly after that as a bonus for the audience (20-21 May), a comet appeared, guiding the direction of the sun. As it approached the luminary long tail-tail appear longer and broke "- said the U.S. space agency, which has ushered Tuesday specialized publication Space.com.
In NASA believe that between coronary emissions and comets kamikaze no connection. In both cases, the release of hot plasma from the corona shone occurred before the comet came closer to the sun enough to affect its magnetic field.
Both celestial body rammed star classified original solar comets, bearing the name of XIX century astronomer Heinrich Creutz. He first proposed a hypothesis about the relationship of space objects, resulting from the collapse of a huge comet centuries ago.
Coronal mass ejections, depending on the brightness of their production of X-rays are divided into five classes: A, B, C, M, X (hereinafter Latin letters). The strongest — emissions or flare of class X, subsequent class is 10 times weaker than the last. For the earth is a dangerous class M or more. Such events can cause magnetic storms, but the immediate danger to the person does not represent, according to ITAR-TASS.
