Scientists discover that "plasma tsunamis" are responsible for sunspots



Rolling plasma waves, known as "solar tsunamis," could cause the sudden end of solar cycles, according to scientists.

Researchers identified so-called "terminator events" that mark the end of sunspot cycles, which could explain the process of how the sun goes from periods of lesser activity to higher activity.

The study, published in the journal Solar Physics, studied nearly 140 years of data collected by NASA's Soil and Solar Terrestrial Relations Observatory and Solar Dynamics Observatory, two spacecraft that have been staring at the sun for years.

According to CNET, when observing UV light from the solar surface, researchers have seen how bright points of light appear at high latitudes and move towards the sun's equator over a period of decades.

As soon as the bright spots have disappeared, another huge burst of activity will take place, marking the beginning of the next sunspot cycle, the researchers said Englisch: www.germnews.com/archive/en/news/news_2006.html. 1996/03 / 22.html We've been on the Watchlist for over a century, but so far we did not know what we were looking for, "said Scott McIntosh, a NCAR researcher working on both studies, in a press release.

Scientists have long wanted to better understand solar cycles – when solar activity peaks, torches, sunspots, and solar storms can affect satellites that are stationed near Earth and Space Weather Collecting information from the Sun's atmosphere.
