Are you sure?  How do you think they know the temps of these heavenly bodies
in the first place?

Ganymede is much colder than Earth, with these daytime temperatures ranging
across
the surface from 90 to 160 Kelvin (or -297 to -171 degrees Fahrenheit).
Jupiter and
its moons receive less than 1/30th the amount of sunlight that the Earth
does, and
Ganymede has essentially no atmosphere to trap heat. Ganymede's day is just
over 7
Earth days long, the same time it takes to orbit Jupiter once. (Courtesy

It's not difficult to measure the if that is what an astronomer really wants
to do either
by infrared emissions or by other techniques.

In what is largely a reversal of an August announcement, astronomers today
said Pluto is
undergoing global warming in its thin atmosphere even as it moves farther
from the Sun on
its long, odd-shaped orbit.

Pluto's atmospheric pressure has tripled over the past 14 years, indicating
a stark
temperature rise, the researchers said. The change is likely a seasonal
event, much as
seasons on Earth change as the hemispheres alter their inclination to the
Sun during the
planet's annual orbit.

They suspect the average surface temperature increased about 3.5 degrees
Fahrenheit, or
slightly less than 2 degrees Celsius.

There will always be "Chicken Littles" around to say the sky is falling, and
they will always
have their followers.
