First Mega-Plasma Eruption Observed On An Alien Star

Solar Plasma Flares

 

A group of researchers has identified and characterized for the first time in a complete way a powerful eruption in the atmosphere of the active star HR 9024, marked by an intense flash of X-rays followed by the emission of a giant bubble of plasma. This is the first time a coronal mass ejection, or CME, has been seen in a star other than our Sun. During the flare, very hot material (between 18 to 45 million degrees Fahrenheit) first rises and then drops with speeds between 225,000 to 900,000 miles per hour.
