Second Alien Life Form May Exist on Earth States Report in Astrobiology Journal

The discovery observations
allowed Bouchy's team to determine the planet's size (about 1. From this distance and the temperature of the
parent star, Bouchy's team estimated the planet's temperature was at least
several hundred degrees Celsius, but they were not able to measure heat or
light emitted directly from the planet. This
temperature is too high for liquid water to exist on the planet or any moons
it might have.
Infrared light is invisible to the human eye, but detectable by special
instruments. From their close orbits, they soak up ample starlight and shine
brightly in infrared wavelengths. First, they used Spitzer to collect the total infrared light from
both the star and its planet."

Davies and Charles Lineweaver propose multiple scenarios for how a
second genesis of life could have occurred. Given that existing life
formed under early Earth-like conditions, then logically it would seem
possible for alternative life to have formed on Earth in a similar
manner and to have survived to the present day. "If the origin of life is
easy, a second example of life may lurk beneath our noses. NASA

How then to detect a "second sample," and is there evidence for
"alien life" on Earth? Davies, from the Australian Centre for
Astrobiology at Macquarie University (New South Wales), and
Lineweaver, from the Planetary Science Institute at the Australian
National University, conclude that life is likely to have emerged on
Earth more than once and, although there are ways to obtain evidence
of alien life, these microorganisms could exist on Earth today and
remain undetected.
"This is the closest extrasolar planet to Earth that has ever been
detected directly, and it presents the strongest heat emission ever seen from
an exoplanet," said Drake Deming of NASA's Goddard Space Flight Center,
Greenbelt, Md. 22.

----If life
readily emerged on Earth shortly after conditions became favorable,
isn't it likely that other genesis events also occurred, creating
additional "alien" life forms that co-exist with known life, asks a
