Tracking the weather on an exoplanet
Scientists have begun gathering increasingly detailed information about the atmosphere and weather on the exoplanet HD189733B, 63 light years away with an orbit that produces a transit every 2.2 days.
It appears that the temperature rises with increasing altitude, reaching 3,000 degrees at the top of the atmosphere. There are also strong winds blowing from the cold to the hot side of the planet.
