Hotter than Hades?

This was interesting, from CNN:

Using infrared data collected by NASA's Spitzer Space Telescope, the researchers calculated that temperatures on the sunlit side of the Upsilon Andromeda b were between 2,550 to 3,000 degrees Fahrenheit (1,400 to 1,650 degrees Celsius) but only minus 4 to 450 degrees Fahrenheit (20 to 230 degrees Celsius) on the dark side. Jupiter, in contrast, maintains an even temperature all around.

For even more info than in the title linked CNN article, I suggesthere
