Something strange is happening on the Sun – 3 June sunspot number dropped to zero, and the solar disk remains empty for three days. NASA’s Solar Dynamics Observatory does not detect any significant dark nuclei.
What does it mean? Solar cycle, like a pendulum, swinging back and forth between periods of high and low sunspot numbers every 11 years. Today, let the sun is a sign that the pendulum has swung in the direction of lower numbers of sunspots. In other words, it installs solar minimum. Continue reading “On the Sun there are no spots”

Discovery sister Sun
The University of Texas found the star HD 162826. Cosmic body, located 110 light-years away, 15 times more than our Sun, and formed in the same star cluster, as our star.
This discovery promises to help scientists better understand how, where and when our solar system was formed, and, quite possibly, will guide us on the best candidates among extra solar planets where life could exist. Continue reading “Discovery sister Sun”
Sun will arrange for earthlings light show
Sun decided to compensate for the discomfort that many people cause geomagnetic storms. After another flash, which already takes a lot of discomfort 75% of the inhabitants of the Earth, the Sun will arrange for earthlings now light show.
A series of powerful flares occurred March 28 – 30 near sunspot AR2017, reports Daily Mail. Sunspots, like any other star, formed in the photo sphere – radiating part of the light, which makes it visible. Continue reading “Sun will arrange for earthlings light show”
Absolutely black sun
The second principle of thermodynamics orthogonality given in the form of the absolute prohibition of obtaining energy from the colder body. It turns out that the body, as it knows who warming, and from whom warmed . However, no mystery there is not.
After all, the colder body gives radiation, and this radiation is absorbed by warmer. Reflection is usually negligible. Not disappear completely as radiation less hot completely, reaching hotter. Just hotter body gives more than the heated body than it receives from. Also, electromagnetic waves are mutually transparent. Continue reading “Absolutely black sun”
The death of the sun
After 1.1 billion years, the sun will begin to change. As the hydrogen engine in which fuel ends, combustion begins to occur and not inwards and outwards. The sun will be brighter. Radiation rise and destroy the hell out of our planet. And it will be so … Astronomer Ron Miller decided to tell available that will look like the death star called the sun with all the details. The average surface temperature increase from 20C to 75C. The oceans, by it, will evaporate, and the planet will become a lifeless desert. As already mentioned, through 1.1 billion years of hydrogen in the sun is over. But the sun uses hydrogen by processing it into helium, so the core of the Sun will consist of the waste helium. He becomes unstable and begins to collapse under its own weight. Continue reading “The death of the sun”
Sun a powerful flare directed towards Earth
Satellites tracking solar activity recorded a powerful outburst on the Sun. Plasma cloud directed towards the earth. Officials monitoring of this outbreak is not reported, but that would assess the strength of emission, just look at the photos received from the STEREO satellites.
Explosions in the Sun
Sun – the only star of the solar system, the yellow dwarf, our daylight. It was around the turn other objects, the planets and their moons, asteroids, meteorites, comets and cosmic dust. And what happens to our luminary has an impact on the entire solar system.
The usual frantic shining
It seemed that there were no signs of the next cataclysm for yellow dwarf in one of the arms of the Milky Way. For several billion years in its core thermonuclear fire raged. Every second, stood out a monstrous energy, equal to the number of explosions difficult Computing the most powerful thermonuclear bombs. The tremendous heat of the nuclear furnaces poured evenly dazzling radiance, supporting life on the third planet. It seemed that it always will be, and in front, especially against the background of short sparks of lives forever… Continue reading “Explosions in the Sun”
Astronomers have spotted a giant UFO near the Sun
The Sun, recently found next to the star strange objects. In the video posted on the Internet show how various unidentified flying objects near the luminary. One thus depart from it, others fly into.
UFO footage – not some amateur, and made with the help of NASA space observatories, looking for the Sun– SOHO and STEREO. Continue reading “Astronomers have spotted a giant UFO near the Sun”
Sun there was a powerful flash
The sun was a powerful release, Steel shot, as predicted yesterday. Ejection almost reached class X and is directed towards the Earth. Flare was accompanied by ejection of solar material, and satellites recorded the increase in the flux of protons to a level dangerous to space technology, as experts have issued a warning. Will flash on the earth is a magnetic storm from 12 to 13 April.
Meteodependent people will feel the effects of emissions today, and the main impact on our planet’s magnetosphere is expected in 2 \ 3 days. Continue reading “Sun there was a powerful flash”
NASA said increase in solar activity
NASA reports that the Sun showing an unexpected activity throwing clouds of plasma in all directions. The explosion began around 0400 UT on March 5 and threw a massive CME into space. This growth in the global solar activity could foreshadow a stormy period of space weather in the coming days.
Served as a catalyst for the explosion of the active region AR1686. This active region will soon turn toward Earth, which means the ego-effective solar activity in the near future.
