Astronomers have discovered never-before-seen meteor-like fireballs in stunning plasma displays on the sun.
spacecraft, marks the first time these impacts have been spotted. The findings have revealed that this process can create short but intense brightening and both an upward surge of stellar material and shock waves that reheat the gas in the corona above the impacts.
Scientists think that this discovery could therefore help solve the mystery of why the corona, the outermost part of the sun’s atmosphere, is much hotter than the layers of the sun below it, despite solar models predicting the sun should become hotter closer to its core. The solar shooting stars were spotted by Solar Orbiter as it observed spectacular plasma firework displays called coronal rain, formed of gas with temperatures upwards of 2 million degrees Fahrenheit.
