The first two paragraphs contain much of the fun:
"Earth-bound astronomers taking Pluto's temperature have confirmed suspicions that the planet is colder than it should be...."

SHOULD
be? Umm, we've only been this smart for a hundred years or so. Pluto and it's counterparts up there have been around for a few billion years longer than we have. Where does the "should" come from? "Should" assumes we know all the variables and can predict when things change, so that we know what "should" happend. Looks like we as a humans don't have all the variables at hand.

Continuing the article:
"Using the Submillimeter Array, or SMA, a network of radio telescopes located in Hawaii, astronomers found that Pluto's average surface temperature was about 43 Kelvin (-382 degrees Fahrenheit) instead of the expected 53 Kelvin (-364 degrees Fahrenheit), which is what the temperature of Pluto's largest moon, Charon, is."

So, we know what the temperature on Charon, is? We can't get the local weatherman to give us an accurate report of weather two days from now, but we can get the precise temperature on a planet's moon 3 billion miles from earth? Am I the only one to see the folly of this?


A conversation from Pluto's moon, Charon:
Mom: "Junior, you can't go out and play today, the weatherman on Earth say it's going to be only 43 Kelvin today, that's even colder than yesterday."
Son: "Aww, Mom, you take all the fun out it!"
Mom: "I think we need to move to Florida, these winters out here are brutal"
 
Wow. A difference of 8 degrees! Clearly we as humans are causing not only global warming on the earth, but solar warming, extending to the furthest reaches of the solar system! In a few more billion years we'll have destroyed the entire solar system!

Hey, thanks for posting that. I was about to put down a deposit on a nice little retirement place up in the Plutonian mountains, but shoot, if it's that cold, I think I'll just pass. I mean -364 is one thing, but -382 -- I don't think I could handle that. . .

I don't believe you need an especially large telescope to see Uranus. In the early morning hours, look South-East near the horizon.
 
I can't believe I'm actually asking this, but how did your automotive lubrication plans involve Uranus?
