Life on other planets: latest discovery comes after string of recent signs of extraterrestrials

Nasa research indicating that half of the stars in the universe are orbited by planets much like Earth has reignited speculation about the existence of alien life.

Numerous scientists and politicians have stated their belief in the existence of aliens and UFOs



Experts examining results from the Kepler telescope have identified more than 1,200 planets in orbit around distant stars, 54 of which are a similar size to Earth and in habitable zones from their suns.

The research follows several recent discoveries which point to the possibility of life on other planets.

Last year, Nasa scientists claimed they had found vital clues which appeared to indicate that primitive aliens could be living on Titan, one of Saturn’s biggest moons.

Data from Nasa's Cassini probe revealed the complex chemistry on the surface of Titan, which experts say is the only moon around the planet to have a dense atmosphere.

Experts suggested that life forms may have been breathing in the planet’s atmosphere and also feeding on its surface’s fuel.
