NASA DISCOVERS NEW PLANET

scientists have developed a metric known
as the Earth similarity index which
measures the similarity of a planet or
moon to earth based on various
parameters such as temperature
atmospheric pressure and habitability it
ranges from 0.0 to 1 with 0.8 and 1
indicating that a planet is similar to
Earth in every aspect
in recent years advances in technology
allowed us to uncover a multitude of
exoplanets and moons with striking
similarities to Earth
one of them was found in 2019 and called
Tea Garden B this is a super Earth
orbiting an m-type star every 4.9 days
at a distance of
0.0252 AU
the Tea Garden star is one of the
closest stars to our solar system
located about 12.4 light years away from
us and although the Red Dwarf is 10
times less massive than our sun and has
a temperature of just about 2700 degrees
Celsius it can still provide enough heat
for its two planets
the two exoplanets are similar to the
inner planets in our solar system and
are only slightly more massive than
Earth both of them are situated in the
habitable zone where liquid water can
exist but tea garden B seems much more
promising and here`s why
Tea Garden B has been given a score of
0.95 ESI meaning it`s the most
Earth-like planet discovered so far
there`s a 60 probability that the
exoplanet has a temperature surface
environment with temperatures ranging
from zero degrees to 50 degrees Celsius
and if its atmosphere is comparable to
Earth`s the surface temperature would
likely be around 28 degrees Celsius
Tea Garden sea however is farther from
its star it has a 0.68 ESI score and
only a three percent chance of having a
warm surface temperature if this world`s
atmosphere is more similar to that of
Mars its estimated temperatures would be
around
-47 degrees Celsius
researchers are not sure what the
atmospheres of the two planets are but
tea garden B and C are tidally locked to
their star and a thin atmosphere could
distribute heat and cold across the dark
and light dividing line
scientists estimate that atmospheres
with densities between 1 3 to 17 times
out of Earth`s could allow for liquid
water to be present on the surface
but that's not all there's a planetary
system that offers some of the best
candidates for extraterrestrial life and
the discovery of its most promising
candidate has just been announced
the tli 700 planetary system is known to
have at least four planets two of which
are in the star's habitable zone the
most promising are toi 700e and toi 700d
both being Rocky and having similar
masses to Earth
toi 700e has an orbital period of 28
days and is 95 percent the size of Earth
while toi 700d has an orbital period of
37 days and is 105 the size of Earth
the toi 700 system has been around for
more than 1.5 billion years giving more
than enough time for biological activity
to take hold and transform the thin
region where the planet's surface meets
its atmosphere into a rich biosphere
if toi 700e and toi 700d have an
atmosphere they would be much warmer
than Earth's average temperature a
potential Game Changer in terms of
habitability
scientists suspect that there could be
more planets located Beyond toi 700d and
if one day we were to discover life
forms on any of these worlds we likely
hope that they resemble those found here
on Earth but is it theoretically
possible that similar life forms could
exist on other planets
evolution is considered a universal law
of nature just like gravity because of
this the principles of evolution found
on Earth can be applied to other planets
due to the process called evolutionary
convergence where unrelated species can
evolve similar adaptations to similar
environmental challenges
the starting point of life on any Alien
Planet must be simple and on many of
them it could have remained like that
but if some of these worlds develop
complex forms of life it could have only
