Scientists Use 'Dyson Sphere' , Signature to Search for , Potential Alien Life.
Decades ago, physicist Freeman Dyson theorized that a
shell made of solar panels that surrounds a star would be
the ultimate energy solution for an advanced civilization. .
One should expect that, within a few
thousand years of its entering the stage
of industrial development, any intelligent
species should be found occupying an
artificial biosphere which completely
surrounds its parent star, Freeman Dyson, 1960 paper, via CNN.
CNN reports that the concept took
hold and the hypothetical megastructures
have come to be called Dyson spheres. .
At the time, Dyson suggested that
these spheres would emit waste heat
as detectable infrared radiation.
The British American physicist suggested
that this unique radiation signature could
be a way of finding extraterrestrial life. .
It would be much more
rewarding to search directly
for intelligence, but technology
is the only thing we have
any chance of seeing, Matías Suazo, Lead study author and a doctoral student
in the department of physics and astronomy
of Uppsala University in Sweden, via CNN.
A new study searched five million stars in the Milky Way
galaxy to find seven candidates that could potentially
be home to an advanced civilization's Dyson sphere.
It’s difficult for us to find
an explanation for these sources,
because we don’t have enough
data to prove what is the real
cause of the infrared glow, Matías Suazo, Lead study author and a doctoral student in
the department of physics and astronomy of
Uppsala University in Sweden, via CNN.

They could be Dyson spheres,
because they behave like our
models predict, but they could
be something else as well, Matías Suazo, Lead study author and a doctoral student

The team's findings were published
in the journal 'Monthly Notices of
the Royal Astronomical Society.'
