Incredible blast on the sun helps scientists uncover new information about the causes of strong solar eruptions and how we might better predict them in the future.
Back in March 2016, scientists used NASA’s Solar Dynamics Observatory and the Sun and Heliosphere Observatory, a joint NASA / European Space Agency (ESA) mission, to observe a dramatic explosion in the Sun. This event demonstrated the characteristics of three different types of solar eruptions, which usually occur separately, but this time clearly happened together. according to NASA… Because it included many different types of events at once, scientists studying the explosion in the new study believe that this strange phenomenon could reveal the causes of all types of solar eruptions.
“This event is the missing link where we can see all of these aspects of different types of eruptions in one neat little package,” says Emily Mason, lead author of the new study and solar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. said in the same statement. “This proves that these eruptions are caused by the same mechanism, only on different scales.”

Typically, the Sun can experience three different types of eruptions: coronal mass ejections (CMEs), jets, or partial eruptions. CMEs and jets are explosive and eject particles and energy into the cosmic vacuum. Jets are ejected as thin beams of solar material, and CMEs create massive bubbles of matter that are pushed out by the sun’s magnetic fields. In contrast to the two, partial eruptions occur from the surface of the Sun, but do not fully venture out into space; the material that erupts just falls back into the sun.
During the March 2016 eruption, scientists observed the eruption of hot solar material from a “magnetically active” region of the Sun’s surface, according to the statement. This ejection was too large to be considered a jet, but not large enough to be called a CME, and soon after eruption, colder surface material began to erupt from the same location before falling back into the sun. This event appears to have the characteristics of all three different types of solar eruptions, which is why scientists believe that they could all be caused by the same phenomenon, and therefore, by discovering the mechanism behind this event, they could explain the origin of all solar eruptions. …
That is why scientists call this event the “Rosetta Stone” eruption, which refers to the Rosetta Stone, an artifact inscribed with hieroglyphs, ancient Egyptian demotic and ancient Greek letters that finally helped scientists decipher ancient hieroglyphs.
After observing the eruption, scientists continue to study the eruption and other similar eruptions, simulating them to investigate the mechanism behind them and the trigger that triggered them. This is important for us here on Earth, in particular, because CMEs emit a large number of charged particles and can interfere with electrical networks on Earth and even pose a danger to astronauts and space technology. So, by better understanding the mechanism of solar eruptions, scientists hope they can better predict them and prevent damage from CMEs.
