Nearby Red Dwarf Star Emits Most Massive Solar Flares yet Recorded

DG CVn

NASA astronomers said they've found long lasting stellar flares on a nearby red dwarf star.

They discovered an initial a series of explosions 10,000 times more powerful than the previous recorded solar flare in space.

Through the NASA Swift mission, they detected the massive superflare from a red dwarf star located in DG Canum Venaticorum (DG CVn), 60 light years away from Earth.

Stephen Drake, a NASA astrophysicist, said flaring episodes on the red dwarf lasted for a day with seven powerful eruptions in the last two weeks.

He said the flares reached a peak of 360 million degrees Fahrenheit, which is 12 times hotter compared to the center of the Sun.

Rachel Osten, one of the astronomers involved in the study, said DG CVn is poorly studied because it isn't on the list of stars capable of producing large flares.

She admitted NASA has no idea the system has massive solar flares. She added that most of the stars lying within 100 light years from Earth's solar system are like the Sun.

There are however, thousands of young dwarf stars born in different galaxies that drift through the Milky Way.

Astronomers said this gives them the best opportunity for a detailed study of the high energy activity produced by these drifting young dwarves.

They assess that DG CVn was born 30 million years ago, which makes it less than 0.7 percent the age of the solar system it came from.

Astronomers explained that stars erupt with flares because in the active regions of the star's atmosphere is a magnetic field that is twisted and distorted.

Magnetic reconnection destabilizes the magnetic field, releasing stored energy called solar flares.

Researchers said the gigantic outburst emits radiation in the electromagnetic spectrum such as radio waves, ultraviolet rays and x-ray light.
