NASA Solar Dynamics Observatory (SDO) has started to reveal the secrets of our nearest star. It has captured some truly spectacular pictures of prominent eruptions from the surface of the sun.
These eruptions are huge and are not solar flares, clarifies NASA spokeswoman Susan Hendrix. These are common occurrence on the surface of the sun and were but a mass of warped plasma shifting to and fro before erupting into space.
NASA spokeswoman Susan stated, “Material on the sun, doing what it always does, dancing and twisting – and in this case erupting off the side of the sun”.
We commonly link the prominence on the Sun’s surface to sun spot and sun flare activities. The prominences including the one captured by NASA’s Solar Dynamics Observatory (SDO) has abilities to influence the Earth’s atmosphere and they can also interfere with the electromagnetic activities. A prominence which is active in nature can erupt suddenly and will be visible after a few minutes or hours.
The prominence has been classified as of M-Class level. Solar flares are categorized by their intensity in the descending order as X,M,B,C and A. X is categorized as strongest and A as weakest in intensity. So a prominence of M intensity can be considered as very intense.
NASA has stated that M-Class eruptions can lead to brief radio blackouts at the Poles, and the radiations could prove to be dangerous to astronauts. The NASA’s Solar Dynamics Observatory (SDO) pictures will help scientists learn the finer details of the Sun’s magnetic field, how it is generated and the effects it will have on life on Earth.
