Did you know that stars have outbursts too? 🌟
For decades, astronomers have known about irregular outbursts from the double star system V745 Sco, which is located about 25,000 light years from Earth. V745 Sco is a binary star system that consists of a red giant star and a white dwarf locked together by gravity.
In 2014, astronomers finally got their chance to see the phenomena, using the Chandra X-Ray Observatory.
In the figure showing the new 3-D model of the explosion, the blast wave is yellow, the mass ejected by the explosion is purple, and the disk of cooler material, which is mostly untouched by the effects of the blast wave, is blue. An extraordinary amount of energy was released during the explosion, equivalent to about 10 million trillion hydrogen bombs.
