An arc eruption of the sun was recorded by NASA̵
The dramatic explosion of the sun reveals new clues as to the causes of these powerful and unpredictable eruptions, according to a new study published this week.
In addition, unraveling the mystery could help scientists better predict the eruptions that cause dangerous cosmic weather conditions here on Earth.
The explosion, which occurred in March 2016, contained elements of three different types of solar flares, which usually occur separately – making the first announcement of such an event, according to a NASA statement.
“This event is a ‘missing link’ where we can see all these aspects of the different types of eruptions in one neat little package,” said Emily Mason, lead author of the new study and solar scientist at NASA’s Goddard Space Flight Center. “This leads to the idea that these eruptions are caused by the same mechanism, only on a different scale.”
According to NASA, solar flares usually come in one of three forms: coronal mass ejection, jet ejection, or partial eruption. Coronal mass ejections and jets are both explosive eruptions that throw energy and particles into space, but look very different.
As the jets erupt like narrow columns of solar material, ejections of coronal mass form huge bubbles that expand, push out, and sculpt from the sun’s magnetic fields.
Partial eruptions, on the other hand, begin to erupt from the surface, but do not cause enough energy to leave the sun, so most of the material falls back onto the solar surface.
During the explosion in 2016, all three types of eruptions occurred in the same event.
That’s why scientists refer to the event as the eruption of the Rosetta Stone, which refers to the Rosetta Stone, an artifact with hieroglyphs, ancient Egyptian demotics and ancient Greek, which helped scientists finally decipher the ancient hieroglyphs, according to Space. com.

“This is important to us here on Earth, especially because coronal mass discharges release large amounts of charged particles and can disrupt useful networks on Earth and even pose a danger to astronauts and space technology,” Space.com said. .
By modeling the eruption in 2016 and others, once discovered like it, scientists hope to be able to understand what root mechanism causes solar flares and determine their characteristics. Finding a trigger could eventually allow scientists to predict when a major eruption could threaten Earth and Mars hours in advance – giving astronauts and spacecraft operators enough time to take precautions, NASA said.
The new study was presented on June 7, 2021 by Mason at the annual meeting of the American Astronomical Society and was accepted for publication in the Astrophysical Journal Letters.
