One of the favorite topics of our news is about moon landing. So, on this day (on September 20, 1970) the Soviet Union's Luna 16 moon probe landed on the moon.
American amateur astronomer Howard Eskildsen made an unusual photo, luminous bridge on the Sun through one of sunspots, whose nature is not fully clear to astronomers. Approximate length of luminous bridge is 20 000 kilometers. Sunspots are dark and cold (relatively) areas of the Sun, that appear in places of output of magnetic fields, impede exchange of plasma between internal and external layers of the star. Luminous bridge often appear before the separation of sunspots in two parts. Some of the studies suggest that the processes taking place in magnetic fields and leading to emergence of luminous “bridge”, are similar with the processes that generate powerful flash in the Sun. Accordingly, it is possible that the luminous bridge is harbinger of a powerful flare on the sun.
