NASA
discovery suggests aliens exist - even on Earth

London:
NASA has made a stunning claim of an "astrobiology finding" that
could suggest alien life exists - even on Earth.
The discovery could prove the theory of 'shadow' creatures which
exist here in hostile environments previously thought
uninhabitable.
The 'life as we don't know it' could even survive on hostile
planets and develop into intelligent creatures such as humans if
and when conditions improve.
Researchers will unveil the discovery of a microbe that can live
in an environment previously thought too poisonous for any
life-form, reports the Telegraph.
The bacteria has been found at the bottom of Mono Lake in
California's Yosemite National Park which is rich in arsenic -
usually poisonous to life.
Somehow the creature uses the arsenic as a way of surviving and
this ability raises the prospect that similar life could exist on
other planets which do not have our benevolent atmosphere.
Lewis Dartnell, astrobiologist at the Centre for Planetary
Sciences in London, said: "If these organisms use arsenic in their
metabolism, it demonstrates that there are other forms of life
than only those we knew of. They're aliens, but aliens that share
the same home as us."
The space agency will announce the full extent of the findings at
a press conference titled "astrobiology finding which will impact
the search for evidence of extraterrestrial life".
Scientists have also estimated that life of some kind exists on
hundred billion trillion Earth-like planets in space.
