2. LIFE ON
EARTH
• Life appeared on Earth '3.8 billion
years' ago.
• The earliest form of life that existed on
earth has evidence in the form of
'biogenic carbon signatures' and
'stromatolite fossils'.
• Life first came into being when the
entire earth was covered with water, a
condition known as Hot Dilute Soup.

3. WHAT IS EXOPLANET?
• An exoplanet or extrasolar planet is a planet outside the solar
system.
• There are 4,379 known exoplanets, or planets outside the Solar
System that orbit a star, as of December 1, 2020; only a small
fraction of these are located in the vicinity of the Solar System.
• Within 32.6 light years, there are 97 exoplanets listed as
confirmed by the NASA Exoplanet Archive.

4. What is
habitable
zone?
Habitable zone, the orbital
region around a star in which
an Earth-like planet can
possess liquid water on its
surface and possibly support
life.
Liquid water is essential to all
life on Earth, and so the
definition of a habitable zone is
based on the hypothesis that
extraterrestrial life would share
this requirement.
Planets in these areas are the
most likely to have
extraterrestrial life.

5. KEPLER SPACE TELESCOPE
• NASA's Kepler Space Telescope was an observatory in space
dedicated to finding planets outside our solar system with a
particular focus on finding planets that might resemble Earth.
• The observatory was in commission for just under 9 years,
from its launch in March 2009 to its decommission on Nov. 15,
2018.
• Kepler also came through on its mission to find a planet
approximately the size of Earth in the habitable region of a star.
The exoplanet, dubbed Kepler-69c, is about 2,700 light-years
away and has a diameter about 1.5 times that of Earth.

6. PROBLEM
• Many scientists are researching about life on other planets. To find
existence of life in outer space, NASA has introduced Kepler
Telescope . According to the fact and figures, Kepler telescope
estimates 40 billion exoplanets to exist in habitable zone in which
water predominantly exist in liquid phase. But there is no sign of life.
So, Life on exoplanets remains as mind boggling mystery to
researchers. Despite having endless possibilities of thriving life on
exoplanets which exists in habitable zone, scientists still are stuck in
endless loop of finding life other Planet. What if we could introduce
life on exoplanets which are in habitable zone?

7. SOLUTIO
N
• Instead of searching life on other exoplanets
scientist could introduce life in nearest
discovered exoplanet which comes under
habitable zone. With the support of Winkler's
method we will determine the Dissolved
Oxygen in those planets.
• Based on the amount of DO obtained we can
conclude which type of microorganisms to
introduce:
• A) If DO level is more, we shall introduce
aerobic microorganisms (Oxygen consuming
microorganisms).
• B) If DO level is less, we shall introduce
Anaerobic microorganisms such as
archaebacteria.

9. VALUES WE LEARNT
• Dissolved Oxygen in Water is most important for
every living thing, so we must take care of our
Earth's water bodies.
• As human we must be precausious and prepared
for everything because we aren't alone
(Extraterrestrial).
• AstroBiology is a field that no one would have
imagined about so we must always think out of the
box to achieve greater heights...
