New measurements for three planets outside our solar system indicate their temperatures remain fairly constant – and blazing hot – 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.

Soon after its launch two years ago by the Canadian Space Agency (CSA), Canada's "Humble Space Telescope" started making amazing observations-beyond the capacity of any other Earth- or space-based instrument. MOST, our suitcase-sized space telescope orbiting at 820 km, can fix its gaze upon a single star for up to eight weeks at a time. And with its unique combination of steady observation time and precision pointing, MOST can look for subtle variations in stars that are impossible to observe...
