Stellar flare hits HD 189733b (artist’s impression)

This animation shows exoplanet HD 189733b, as it passes in front of its parent star, called HD 189733A. Hubble’s instruments observed the system in 2010, and in 2011 following a large flare from the star (depicted in the video). Following the flare, Hubble observed the planet’s atmosphere evaporating at a rate of over 1000 tonnes per second. Here, the escaping atmosphere is seen silhouetted against the starlight.

In this video, the surface of the star, which is around 80% the mass of the Sun, is animated based on observations of the Sun from the Solar Dynamics Observatory.
