COSMOS: small dinasaurs huge Fishes like Megaladon and mammals like giant elephant mammath

 Cosmos as u had already heard or even not .I m gonna tell u the whole details about our cosmos ( universe , galaxies , stars, planets , cosmic dust ; etc )


History of COSMOS


1. COSMOS


Cosmos was originated about 20 billion yrs ago (bya) and it was originated due to a huge explosion unimaginable in physical terms also called BIG BANG .

AFTER the explosion the clouds of dust settle down and get settled some forming galaxies of the early universe .

2. MOTHER EARTH

EARTH was supposed to originated about 4.5 billion yrs ago (bya) just as a cloud of cosmic dust and huge amount of energy and heat due to which the early earth surface was extremly hot ( >400°F ) 

As the time passed on the cosmic calender the huge clouds of dusts and particles condensed into rocky planet but the temperature was still high.

Now the earth looks like a red hot giant due to volcano eruptions and extremly high temperature .

As the temperature falls it helped in origin of life in the form of non cellular forms about 3 billion years ago. But some organisms left their presence in rocks about 3.7 billion years ago.


There after life evolved to cellular forms possibly originated till about 2 billion years ago. 


As the time passed and years folded on the cosmic calender the evolution of life continued till present day and will continue in the future .

Exoplanets holds a better survival than Earth

 Exoplanets holds a better survival than Earth ■Exoplanets are those planets that have a rocky surface like Earth, Mars etc. and found outside our solar system.  We have heard a term SUPER - EARTH A Super earth is  an extra solar planet with a mass higher than our earth but lower mass than " ice giants" such as Uranus, Neptune. examples of super earth are COROT - 7b{ICARUS}, GJ1214b{SHESHA}, KEPLER - 440b. ■  Reasearchers had already discovered many planets similar to our mother EARTH but very recent studies has opened up new mysterious facts revealed "these SUPER - EARTHS full of Hydrogen and Helium. Featured Articles  💙 Mission Mangal ■SOME FACTS ABOUT HYDROGEN AND HELIUM 1} HYDROGEN - ●Most abundant element on Earth. ●Alternative fuel source [with a very high energy] ●fuel cells in rockets or gasoline powered cars. 2}HELIUM - ●Second most abundant element in the universe. ●used in air balloons. ●source of energy of sun and stars. ■These exoplanets  ...

Research: The mass of a black hole is 4.4 times the mass of sun | Binary systems | black hole - ISC

 Research: The mass of a black hole is 4.4 times the mass of sun|Binary systems|black hole NASA  and European Space Agency(ESA) for the first time measured the mass of a black hole moving in space with the one and only The Hubble Space Telescope (HST). Until now the mass of a black hole determined on the basis of position of binary systems or galaxies. Large black holes were belived to occur only with companion stars , but for the first time a single black hole has occured .  The discovered black hole is believed to be about 80 light years away from our galaxy. Earlier it was estimated that it is 5000 light years away. Stars increase its mass by interacting with another star or its comapnion star. When the mass increased it explodes called Supernova.  Remants called as 'neutron star'. When remanant is bery large it is called "black hole".  According to scientists the mass of a neutron star is between 1.6 to 4.4 times the mass of sun. The discoveries till n...
