Top 10 facts about space

 1. There are over 500 billion stars in our galaxy alone, and some estimates put that number at trillions of stars across the universe.

 2. Our sun is 4.6 Billion years old and has used up 1/5th of its fuel supply. By the time we reach the end of this century, our Sun will no longer be a viable energy source.

 3. We have discovered 17 exoplanets (planets around other stars) outside of our solar system. Of those 17 planets, 2 actually orbit their star inside their habitable zone. This means that these planets do not burn off all of their atmosphere into space like Mercury does nor freeze solid like Venus. If life can exist here, then perhaps it can exist elsewhere in the Universe.

 4. In 2011, Scientists announced the discovery of Kepler-22b; a planet just 55 light-years away from Earth. They determined that the planet was likely rocky and potentially had liquid water flowing on its surface. So it may be possible that there could be life out there somewhere else in the Milky Way Galaxy.

 5. In 2013, NASA scientists revealed that they have found 100 Million Earths orbiting Proxima Centauri, a red dwarf star only 4.24 Light Years away.

 6. In 2014, Astronomers using ESO's Very Large Telescope announced the first ever image of a black hole being sucked in matter. As a black hole sucks in matter, it grows larger and larger until it reaches a point where gravity becomes so strong that even light cannot escape it.


 7. If we could actually travel to other planets, we would probably discover that they're not all that different from Earth.

 8. There are over 700 moons around planet earth.

 9.NASA says that there are more than 100 billion galaxies in our universe.

 10.Our Sun is just one star out of hundreds of billions of stars in our galaxy.

 ● We live in a galaxy that's part of a cluster called the Virgo Supercluster. That's a pretty big collection of something like 2 million galaxies.

 ●The Milky Way Galaxy is estimated to be somewhere between 200-400 thousand light years wide.

 ● The universe is expanding at an incredible speed.

 ●Even though we can't see it, gravity still holds us down.

The sun goes through cycles lasting roughly 11 years. Some scientists predict that this cycle will end soon.

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...
