Extra Terrestrial Life

Are we alone? This question is nearly as old as humanity itself. Today, this question in astronomy focuses on finding life beyond our planet. Are we, as a species, and as a planet, alone? Or is there life somewhere else?

If you grade earthlings on a cosmic curve, as recently hashed out by astrophysicists, we're at the head of the class.

The Giant Magellan Telescope (GMT), scheduled to be completed by 2024, will have a resolution 10 times that of the Hubble spacecraft.

Signs of alien life will be detected by 2025, while "definitive evidence" of extra-terrestrial beings may be found within the next 20 to 30 years, top NASA scientists say.

There could be life on at least half-a-dozen other worlds - besides the Earth - and it may take 20 more years to find them, astronomers have announced.

Scattered across 11 planetary systems, their temperatures would be too hot for survival, as they all circle their stars closer than Venus, the second planet from the Sun, which has a surface temperature of 464 Celsius (867 F).

For all the triumph of NASA's 1976 Viking mission, which put two unmanned spacecraft on Mars, there was one major disappointment: The landers failed to find carbon-based molecules that could serve as the building blocks of life.The complete lack of these organic molecules was a surprise, and the notion of a desolate, lifeless Mars persisted for yea...

King of Rock and Roll Elvis Presley reportedly believed in extra terrestrial beings all his life and also spotted a number of UFOs.
