Sizzling Weather On a Dive-Bombing Planet

The Bad Astronomer writes "A massive planet orbiting the star HD 80606 is on a roller-coaster orbit: it dive bombs the star, in just 55 days dropping from over 120 million km to just 4 million km from the star's surface! Astronomers used the Spitzer Space Telescope to observe the heat from the planet as it gets blasted by its star, and used that data to make a beautiful computer-modeled image of what the planet must look like. Their results: an ube-rviolent storm that acts as if a bomb were exploded in the planet's atmosphere."

    Second they said it produced explosive winds, up to 5 km/s. (Or "fucking unbelievably fast" in imperial units;) Because the air heats from 500 degrees to 1200 degrees on the hot side within hours, and expands, rushing towards the colder side.

    The wind speed is higher than the conditions at the hypocenter when the bomb was dropped on Nagasaki

    The resulting explosion had a blast yield equivalent to 21 kilotons of TNT. The explosion generated heat estimated at 3,900 degrees Celsius (7,000 degrees Fahrenheit) and winds that were estimated at 1005 km/h (624 mph).

    If there are any aliens on that planet they must be badass shitkicking sons of bitches. Ideal recruits for my Imperial Guard.
