The solar plasma eruption was nicknamed "dragon tail" by NASA scientists. It rose from the surface of the sun on the 31st and was discovered by NASA's solar dynamic observation satellite. This powerful satellite constantly records the sun's climate in different light wave lengths.

This video of the dragon tail solar eruption shows the curls of solar plasma stretching out from the Northeast surface of the sun in four hours. Towards the end of the eruption, the coil began to decompose. Solar Dynamics satellite officials described the video: 'some of the plasma was released into space, but it was unable to escape the sun's gravity. It's not surprising that the plasma eventually falls back to the surface of the sun, because the sun's gravity is very strong. '
One end of the filaments is connected to the surface of the sun, and the other end can extend to the outer atmosphere of the sun. This scene is called the corona. Solar Dynamics satellite officials explained that the filaments only lasted about a day, while stable solar eruptions could survive for months at a time.
NASA's solar dynamic observation satellite is one of several satellites that continuously monitor solar flares, eruptions and other space climate signals. The sun is currently in the active phase of the 11 year solar cycle and is expected to reach its peak in 2013. The current solar climate cycle is considered to be in the 24th solar cycle.
