✘ We human beings have been venturing into space
since October 4, 1957, when the Union of Soviet
Socialist Republics (U.S.S.R.) launched Sputnik, the first
artificial satellite to orbit Earth. This happened during
the period of political hostility between the Soviet
Union and the United States known as the Cold War.

- 9. Like every other
machine,satellites do not
last forever. Whether
their job is to observe
weather, measure
greenhouse gases in the
atmosphere, or point away
from Earth to study the
stars, eventually all
satellites grow old, wear
out, and die, just like old
washing machines and
vacuum cleaners

- 10. However, some of these
satellites will remain in
orbit for a very, very long
time. Perhaps someday in
the future, humans may
need to send “space
garbage trucks” to clean
these up. But for now, at
least, they will be out of
the way.

- 12. The possibility of life on Mars is a subject of
interest in astrobiology due to its proximity
and similarities to Earth. To date, no proof
of past or present life has been found
on Mars. Cumulative evidence suggests
that during the ancient Noachian time
period, the surface environment of Mars
had liquid water and may have
been habitable for microorganisms, but
habitable conditions do not necessarily
indicate life

- 14. ✘ Kepler-452b (a planet sometimes
quoted to be an Earth 2.0 or Earth's
Cousin based on its characteristics;
also known by its Kepler Object of
Interest designation KOI-7016.01) is
a superEarth exoplanet orbiting
within the inner edge of
the habitable zone of
the sunlike star Kepler-452 and is
the only planet in the system
discovered by Kepler. It is located
about 1,800 light-years
(550 pc) from Earth in the
constellation of Cygnus.

- 16. A black hole is a region
of spacetime where gravity is so strong
that nothing – no particles or
even electromagnetic radiation such
as light – can escape from it. The theory
of general relativity predicts that a
sufficiently compact mass can deform
spacetime to form a black hole.
he boundary of no escape is called
the event horizon.

- 18. If you could travel
outside the Milky Way and
look down on it from
above, the galaxy would
look like a giant spiral in
space as shown in the
following image.

- 19. ✘ From the Earth, the Milky Way looks
like a bright hazy band of light across
the sky, mixed in with dark dusty
patches. This was called Galaxies
Kuklos by the Greeks which means
the Milky Circle because they thought
it looked like milk spilled across the
sky. The Romans changed the name
to Via Lactea which means the Milky
Road or the Milky Way.

undiscovered, which has also possibility of alien life with other
supernatural bodies
