For the first time, astronomers say they've detected a superstorm in the atmosphere of an exoplanet, a planet about 60 percent the mass of Jupiter, orbiting a star about 150 light-years from Earth.
In the journal Nature, the team of astronomers from the U.S. and the Netherlands wrote that in the atmosphere of the planet HD209458b, a super wind is blowing at a speed of about 3,100 to 6,200 mph.
"HD209458b is definitely not a place for the faint-hearted ???" said Ignas Snellen, who led the team of astronomers.
