The Sun discovered the spot size exceeding the Earth


Astronomers representing the American space Agency NASA drew attention to the huge spot that appeared in the Sun. In all probability, formed it some time ago, but only recently the Land was in such a position relative to the lights that the object was visible. Specialists dedicated to his observation a short video.

In the video you can see how the spots with a black center, and orange edges “float” in the frame from left to right, gradually changing the form, and towards the end of the video two large black area merge together. As the scientists explain, the appearance of the spots on the Sun, like all similar objects, was triggered by outrage at this plot of the magnetic field luminaries

Experts also “added” to the movie the blue dot that represents the approximate size of the Earth, if she was captured from the same distance as the frames. As you can see, a dark spot, which is a Central part of the spots, much larger than our planet, even at the scale of the Sun and it may not seem too large.

It should be noted that now the sunspots on the Sun too much, and last year for the first time in a long time, experts have recorded the moment when they disappeared completely. This is due to the fact that the light entered the less active phase of its eleven-year cycle. For this period less characterized by the formation of spots and coronal mass ejections, sometimes becoming the cause of magnetic storms on Earth, but often appear in coronal holes. Also, experts claim that this during times of minimum solar activity, the upper layers of the Earth’s atmosphere become more cold and dense, causing space debris is closer to the planet, and also increases the probability of falling on the Earth of radiation from deep space, the planet from which usually protects the heliosphere.
