The Blistering Hot Exoplanet Where It Snows

cylonlover writes "Today's weather on HD 189733b: It will be hazy with high wispy clouds. The wind will be steady from the east at speeds approaching 6,000 miles per hour (9,656 km/h). Daytime temperatures will average a balmy 800C (1,472F), while the equatorial hot spot at 30 degrees longitude is expected to top 900C (1,652F). But, there is a high chance of silicate snow showers, with accumulations expected except in the vicinity of the hot spot. Just how much can astronomical observations tell us about exoplanets — those worlds orbiting other stars in our galaxy? With patience and cunning, more than you might think."

It's all speculation until you go there

Take Mars for instance. There was a lot of good scientific guesswork based on indirect observation, but when they finally sent a probe there, all the talk about canals and whatnot faded away...

Does being Welsh make you arrive 63 years late at 99.99% the speed of light?
