HD 189733b: Astronomers Measure Wind Velocities on Hot Jupiter Exoplanet

Using observations from the High Accuracy Radial velocity Planet Searcher (HARPS), a high-precision spectrograph on ESO’s 3.6-m telescope at La Silla Observatory, astronomers have managed to measure wind velocities on opposite sides of an exoplanet called HD 189733b, the closest hot Jupiter to the Solar System. HD 189733b is a gas giant planet with a [...] —> Read More
