EARTH LIKE PLANETS FOUND
Exoplanet
or extrasolar planet is a type of planet which does not revolve around the sun but instead they revolve around
a different star. But these
exoplanets were believed to facing only the one side of the star and even the possibility of having water
they were unable to have survival.
Only one side was facing the star and the other side, But Astronomers claims now that these exoplanets
actually rotate and they exhibit
the pattern of having day-night cycle thus the increasing the chances to have an alien life. Dr Leconte, a
postdoctoral fellow at the Canadian
Institute for theoretical Astrophysics (CITA) at the University of Toronto said that they if they are
correct on they are on right path
of their search then there is no cold night side on exoplanets which causes the water to remain trapped in
the gigantic sheets of the ice. Dr
Leconte and his team used three dimensional climate models to understand the atmosphere effect of
the other planet.
Astronomers are still waiting for the
evidence to prove the alien life.
The arguments suggest that there are chances of exoplanets to have similar atmosphere like earth. In earth, the heated UV rays of the sun pass through
the thin sheet of the atmosphere
which minimizes the effect of these rays result the moderate
climate on the planet for the survival. The researchers say that a large number of exoplanets should not be in
the synchronous rotation as they were previously
assumed but their models show that
they have day night cycle. This makes them more similar to earth, but the duration of their days could
be few weeks or of months.
In separate searches the astronomers say that
there are two unknown people
waiting to be discovered beyond Pluto resulting in the changing the position of the object away from Neptune causing
them to behave strangely
trans-Neptunian objects.
