Witnessing Massive Eruption

According to a new study, astronomers may have discovered for the first time a sunlike star erupting with a massive outburst 10 times larger than anything similar ever witnessed from our sun.

According to the researchers, the new findings may offer insight on the effects such huge outbursts may have had on early Earth when life first emerged, as well as the effects such big outbursts may have on present Earth and human societies.

Flares from our sun are common, and each one has the energy of millions of hydrogen bombs bursting at the same moment.

Solar flares are frequently accompanied by filaments, which are large, brilliant tendrils of solar plasma. They can eject coronal mass ejections, which are magnetic bubbles of superheated plasma hurtling across space at millions of miles per hour.

When coronal mass ejections collide with Earth, they can fry satellites in orbit and cause massive geomagnetic storms, which can disrupt electrical systems. A coronal mass ejection, for example, blacked out the whole Canadian province of Quebec in seconds in 1989, damaging transformers as far away as New Jersey. It also nearly knocked out electricity grids across the United States, from the mid-Atlantic to the Pacific Northwest.

In a statement, study co-author Yuta Notsu, an astronomer at the University of Colorado Boulder, stated, “Coronal mass ejections can have a catastrophic impact on Earth and human culture.”

The researchers looked to EK Draconis, a star around 111 light-years from Earth, for the current study. EK Draconis is a yellow dwarf similar to the sun, although it is much younger, ranging in age from 50 million to 125 million years. Notsu explained, “It’s what our sun looked like 4.5 billion years ago.”

Previous research indicated that EK Draconis frequently erupted with flares, suggesting that scientists keeping an eye on it might strike it rich in their search for superflares and large coronal mass ejections. The new study used NASA’s Transiting Exoplanet Survey Satellite and Kyoto University’s Seimei telescope to observe EK Draconis from January to April 2020. They also used the Nayuta telescope at the Nishi-Harima Astronomical Observatory.

Propositions by Scientists

The scientists’ hypothesis paid out on April 5, 2020, when they detected a superflare that was followed by another superflare about 30 minutes later. What looked to be a coronal mass ejection moving at around 1.1 million mph was compared to this (1.8 million kph). Its mass was believed to be ten times greater than the greatest known solar coronal mass ejection.

The crew was only able to catch the first phase of the coronal mass ejection, so it’s unclear if it fell back onto the star or was expelled into space, according to Notsu. To explore the later phases of coronal mass ejections around other stars, future research should use a variety of telescopes, he said.

These findings show that the young sun may have blasted out massive coronal mass ejections, which may have had an impact on the early Earth. “In other words,” Notsu told reporters, “coronal mass ejections may be significantly tied to the environment where life was born.”
