NASA scientist expects to find aliens within 20 years

We could find alien life within the next few decades, according to NASA scientists who are working around the clock to figure out if we are alone in the universe.
The pace in which scientists are discovering potentially habitable planets in our cosmic neighborhood is soaring.
When Pluto was discovered in 1930 it was considered a one-of-a-kind feat for science, but less than 100 years later we have discovered hundreds of thousands of exo-planets in other star systems.
Anthony del Genio of NASA’s Goddard Institute For Space Studies believes we could find alien life within a lifetime.
He said: “I think that in 20 years we will have found one candidate that might be it.”
Stargazers are searching for clues on our own planet to understand how it fostered life.
Using a collection of hi-tech telescopes and radars to spot and analyze planets in other solar systems and galaxies, they have managed to find around 3,500 potential Earth-like worlds.
They are so convinced, a spaceship is being sent to Europa to see whether alien life could be swimming in its giant frozen lakes.
To be a potential new home, liquid water is necessary so the surface of an alien world needs to be a temperature that allows liquid to be present for billions of years to allow life to thrive.
If it’s too far from its parent star it will be too cold and its oceans will freeze.
But if it’s too close the light from the star will be so intense it could evaporate the oceans and blast it with deadly radiation.
Planets in the process of losing their oceans this way are said to have entered a “moist greenhouse” state and will have a moist stratosphere.

Space is weird. It’s full of weird rocks, weird balls of gas, weird stars, and weird things that we can’t even properly categorize. It’s also full of weird sounds, and if you spent a moment to sample NASA’s Halloween playlist of spooky space noises, you know exactly what I’m talking about. Some of the noises...
If the “truth is out there,” scientists are determined to find it – so much so that they've spent a message into space trying to contact aliens. But a response could take 25 years – if it comes at all. Messaging Extraterrestrial Intelligence (METI) International sent an encoded message into space using radio waves known...

For such a tiny little world, Pluto sure has gotten a lot of attention in recent years. After being demoted from “planet” to “dwarf planet,” Pluto remains the subject of many scientific endeavors and studies, and new research has perhaps finally solved one of the planet’s most puzzling mysteries. Compared to Earth, Pluto is a...
