Coronal hole in the southern hemisphere, the sun continues to rise and spewing streams of solar wind into space. This picture was taken by NASA satellites, the morning of 23 January.Coronal holes are places in the solar atmosphere, where the sun's magnetic field opens and allows the solar wind to erupt into space. The flow of solar wind flowing from this coronal hole is expected to reach Earth's orbit on January 26-27. Whether it will be a devastating blow to our planet, scientists still can not tell.

According to information obtained from the probe Voyager 1, the edge of the solar system and deep space there is a kind of customs. Where the magnetic field lines generated by the sun and the presence in the solar wind undergo reconnection with the field lines of the magnetic field of the interstellar medium.
According to journalists, the device is now Voyager, zpauschenny in 1977, is close to the edge of the heliosphere, the solar region of space where solar wind plasma is moving relative to the sun at supersonic speed. As explained by astrophysicists from outside the heliosphere bounded collisionless Read more [...]
It appears, on the border of the solar system and deep space there is a kind of customs. Where the magnetic field lines generated by the sun and the presence in the solar wind undergo reconnection with the field lines of the magnetic field of the interstellar medium. This became known as information received from the probe Voyager 1, which so far they can not leave the solar system. Now a veteran Space Research, launched in 1977, the American unit Voyager 1, is close to the edge of the heliosphere, the area of the solar space in which the solar wind plasma is moving relative to the sun at Read more [...]
Venus Express spacecraft will allow experts to the European Space Agency to conduct unique observations of Venus during the reduction in solar wind pressure. As it turned out, the ionosphere, located on the shady side of the planet is inflated like a comet's tail. Ionosphere is called the region of ionized gas that surrounds the main part of the atmosphere. Shape and density of the ionosphere depends on the magnetic field of the planet. For example, at the Earth, which is characterized by a strong magnetic field, the ionosphere in the relative degree of stability. Venus is the self-magnetic Read more [...]
The powerful flow of the solar wind from coronal holes unusually large (~ 550 km / s) called the "turbulence" of the magnetic field of the Earth, and a series of auroras.
In Alaska, the night show was bright enough to watch it in the light of the full moon, said Ronn Murray of Fairbanks. "Very bright moon lit surroundings, while overhead dancing northern lights."

A small increase in velocity of the solar wind was enough to spark auroras around the Arctic Circle, December 15 Tromsø, Norway, and it was very bright - the land was almost as green as the sky.Strong auroras are possible on 17-18 December, when the faster moving flow of the solar wind reaches the Earth's magnetic field. NOAA forecasters estimate 20% chance of polar geomagnetic storms.
