Wind hot enough to melt lead rushes around exoplanet at supersonic speed

First of all, Pound360 is utterly amazed that, not only are we aware of planets circling other stars, but we are able to make predictions about weather patterns on them.

In the latest news along this front, researchers are convinced one exoplanet has winds blowing up to 7,000 miles per hour (fast enough to circle the Earth in the time it would take you to watch an extended version of Return of the King) pushing air that exceeds 1,000 degrees Fahrenheit (lead melts around 325 degrees). This according to
a report at National Geographic.

The planet, a gas giant (like Jupiter) which circles star HD189733b in the constellation Vulpecula, has a very tight orbit (20-times closer to it's star than the earth is to the sun) and does not rotate on its axis. Despite that fact, its dark side is 1,300 degrees Fahrenheit.

Using computer models, researchers have shown weather patterns are pushing hot winds from the star-side to the dark-side and heating it up.

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
