First, NASA's Swift telescope detected a furious X-ray flare from that distant star. Then, the Hubble Space Telescope observed as the nearby planet's upper atmosphere was blown away. The flare was just like the ones burped out by our Sun, but much stronger. In fact, scientists calculate that the planet received "three million times as many X-rays as Earth receives from a solar flare at the threshold of the X class."
In their observations, researchers found that at least 1,000 tons of gas were being ejected from the planet's atmosphere every second, with speeds that reached more than 300,000mph (482,803 km/h). What an amazing and frightening view this must be.
According to lead researcher Alain Lecavelier des Etangs at the Paris Institute of Astrophysics (IAP), this is "an unprecedented view of the interaction between a flare on an active star and the atmosphere of a giant planet."
