Video: Exoplanet Gets Blasted by Eruption From Host Star
Astronomers have discovered variations if the atmosphere of a faraway exoplanet after a powerful eruption of the host star. Using data from NASA's Hubble Space Telescope, they discovered that HD 189733b, was releasing about 1,000 tons of gas every second. The planet is so close to its host star that it completes an orbit every 2.2 days. They believe the eruption from its host star, called HD 189733A, caused this spike.
