How many of you believe in aliens ?

By the end of this presentation , I hope all of you start believing in Aliens.

What are Aliens ?• Belonging to a foreign country.

• Any species of plant or animal intentionally or inadvertently introduced into an ecosystem other than its own.

• Creatures who comes in U.F.O from other planets.

Questions in your mind :-

Do they exist ?

Where they live ?

What they eat ?

How do they communicate ?

What are their genetic code & DNA?

WHAT IS LIFE ?

The condition that distinguishes animals and pants from inorganic matter , including the capacity for growth , reproduction , functional activity , and continual change preceding death.

What is necessary for life to exist ?

Liquid water

Atmosphere

Certain important elements, like carbon and nitrogen, which is necessary for cells to form.

Environment, as it can’t be constantly hit with meteorites.

Magnetic field , so that life can be saved from harmful radiations of sun.

Earth like planet

• Gliese 832c have almost same conditions that earth have.

• But it is 16 light years away.

Places where life can exist in our solar system

Moon

Mars

Europa , Jupiter’s Moon

Titan , Saturn’s moon

Enceladus , Saturn’s moon

Comets

MoonThe moon was confirmed to have water in2009 when a crater was investigated by a spacecraft crashing into it.

Unfortunately, it has no atmosphere

MarsIt was thought to have an atmosphere once upon a time, but when it’s core cooled and stopped, causing the magnetic field to go away, letting the Sun’s solar winds to tear it’s atmosphere away.

Mars RockBacteria was found in Mars rock ALH84001, where it was fossilized.

First solid evidence of the existence of extraterrestrial life.

EuropaIt is an icy world,

but it may have oceans underneath the ice as deep as nine times the deepest ocean on Earth.

TitanSaturn’s largest moon, has lakes of liquid methane on the surface and a heavy atmosphere. This is the first body outside of Earth known to have surface liquids.

Enceladus• It discovered plumes

of water vapour erupting into space from long fractures around the south pole.

• there is an ocean, possibly as much as 10km in depth.

Meteorite & CometsMeteorite contains common amino acids such as glycine, alanine and glutamic acid.

The idea that comets brought water to Earth gained momentum late last year, when astronomers announced ocean-like water in Comet Hartley 2.

Drake EquationThe equation was written in 1961 by Frank Drake not for purposes of quantifying the number of civilizations.

According to this equation there were probably between 1000 and 100,000,000 civilizations in the Milky Way galaxy.
