Observations from NASA's Spitzer Space Telescope reveal a distant planet with a warm spot in the wrong place.
NASA's Spitzer Space Telescope is about to use its last drop of the coolant that has chilled it for the past five-and-a-half years.
New measurements for three planets outside our solar system indicate their temperatures remain fairly constant â€“ and blazing hot â€“ from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent darkness.
