Have scientists found an alien city?

A huge alien planet 44 light years from earth in the constellation Andromeda is baffling scientist with a very strange "hot spot" on it's side.

The planet in question, known as "Upsilon Andromedae b" (catchy eh!) is a large gas giant like our own Jupiter and is "tidally locked" meaning that it doesn't spin as orbits it's star, one side remains facing the fierce glare at all times. You would therefore expect the hotest part of the planet to this side, but it isn't...

A "spot" on the other side of the planet is much hotter and no one has any good idea why, unless perhaps it's the heat signature of an Alien City?

You can see an in depth report of this over at Discover.
