NASA: Alien Life Can Be Identified By 2025

NASA scientists spot alien life---in their foresights of the future.

The scientists confirm that alien life forms will be identified by 2025, while "definitive evidence" of extra-terrestrial forms can be found in the next 20 to 30 years.

"I think we're going to have strong indications of life beyond Earth within a decade, and I think we're going to have definitive evidence within 20 to 30 years," Nasa chief scientist Ellen Stofan said, according to timesofindia.

Stofan was addressing a panel discussion that debated the issue of spotting alien lives in outer space. "We know where to look. We know how to look. In most cases we have the technology, and we're on a path to implementing it. And so I think we're definitely on the road," Stofan added.

According to cnn, the discoveries have been supported mainly by the Hubble Space Telescope.

"Scientists using NASA's Hubble Space Telescope recently provided powerful evidence that (Jupiter's moon) Ganymede has a saltwater, sub-surface ocean, likely sandwiched between two layers of ice," the agency noted.

However, the scientists were not referring to large life forms, or "little green men", but microorganisms.

John Grunsfeld, associate administrator for Nasa's Science Mission Directorate, also explained that various signs of life will be detected in the solar system as well as out of it.

"I think we're one generation away in our solar system, whether it's on an icy moon or on Mars, and one generation [away] on a planet around a nearby star," Grunsfeld said.

He said that our space systems as well as the Milky Way galaxy are full of inhabitable life forms that we know about. For instance, Jupiter moons Europa and Ganymede, as well as the Saturn satellite Enceladus show oceans of water. Most of the oceans had covered Mars in the past, and some dark streaks even today may be indications of water.
