The sun is always active. The latest video published by NASA shows sunspots in an unstable condition, seen blazing in the sun.
This series of eruptions from sunspots for approximately five hours was recorded by NASA's Solar Dynamics Observatory (SDO) facility on October 26, 2021 yesterday.
Sunspots are areas that appear dark on the Sun's surface, because their temperatures are lower than other areas. However, sunspots are still very hot, past 3,500 degrees Celsius.
Sunspots are caused by intense magnetic activity. This activity almost always culminates in a solar flare and mass ejection, as radiation and nuclear gases in the Sun make their way into the cosmos.
Sunspots can be larger than Earth. Currently, there is no impact from the activity because it is moving away from Earth. Scientists will be able to examine it more clearly when the Sun rotates toward Earth.
The Solar Dynamics Observatory (SDO) itself is a NASA satellite that has been observing the Sun since 2010, launched from the base of the Cape Canaveral Space Force Station in the Florida area.
"At least half a dozen explosions appear in this short video from SDO. The explosion site is hidden behind the edge of the Sun. It is almost certain that these sunspots are unstable," SpaceWeather said.
If solar flares, which are bursts of radiation from sunspots, are strong enough, they can damage satellites or interfere with radio signals on Earth.
Solar flares can cause solar storms. In 1859, there was a solar storm which was called the most powerful. One of the consequences was the breakdown of telegraph systems throughout Europe and North America with enormous losses at the time.
