In the young star EK Draconis, similar to our sun and located 111 light-years away in the constellation of the Dragon, researchers observed an extremely powerful explosion and a coronal mass ejection ten times higher than the ones recorded in the Solar System. .

A group of scientists, including astrophysicist Utah Notsu at the University of Colorado at Boulder, have published the findings study In Nature Astronomy.

The study explores a stellar phenomenon called a coronal mass ejection, sometimes known as a solar storm.

Notsu to explain That this type of eruption occurs on the sun regularly and consists of clouds super hot particles, or plasma, that can travel through space at millions of kilometers per hour.
This material flow can cause a mess. If a coronal mass ejection hits Earth, it could happen burning satellites into orbit and shutting down the networks that power entire cities.
In the recently published study led by Kosuke Namekata, a scientist at the National Astronomical Observatory in Japan, it was suggested that the launch could get worse. In the research used by the team Terrestrial and space telescopes To watch the star EK Draconis, which looks like a modern version of the Sun.

In April 2020, astronomers observed the aforementioned star ejecting a cloud of plasma with a mass of one quadrillion kilograms, more than ten times the strongest coronal masses ever recorded from the Sun like stars.

An astronomical event can serve as a warning of how dangerous weather conditions in space can be.

“Theoretically, this type of large mass ejection could also occur on our sun,” Notsu said. “These observations could help us better understand how similar events affect Earth, and even Mars, over billions of years.”

According to the expert, the curious star is about the same size as the Sun, but only 100 million years old, and in a cosmic sense it is a relatively young star.

“This is what our sun was like 4.5 billion years ago,” Notsu noted.

at the end of october NASA revealed a massive solar explosion From class X1, any of the strongest class.

as Massive eruptions of radiation from the sun They throw charged particles out of the star. Explosions are classified into a system where Class C corresponds to relatively mild, Class M to moderate, and Class X to strong.
