Space is so vast and interesting, we can say that the space is infinite and there are so many things in space which are still unknown for humans. There are so many galaxies in the universe few of them are known to us and most of them are still unknown. So till now we discovered very small portion of universe and Scientists/researchers found so many interesting facts about space. Some of them are list below :

1) The footprints on the moon
will be there for 100 million years.

2) If two pieces of the same type
of metal touch in space they will permanently bond.

3) There is floating water in
space. (Astronomers have found a massive water vapor cloud which holds 140
trillion times the mass of water in the Earth’s oceans somewhere around 10
billion light years away – making it the largest discovery of water ever found.)

4) Space is completely silent.

5) The hottest planet in our
solar system is 450° c. (Venus is the hottest planet in the solar system and
has an average surface temperature of around 450° C.)

6) The moon was once a piece of
the earth.

7) Neutron stars can spin 600
times per second.
8) There may be life on mars.

9) The largest known asteroid is
965 km wide.
10) Nobody knows how many stars are

12) If a star passes too close to
a black hole, it can be torn apart.

13) Our solar system is 4.57
billion years old.

14) A light-year is the distance
covered by light in a single year.
15) The Milky Way galaxy is
105,700 light-years wide.
16) Because of lower gravity, a
person who weighs 220 lbs on Earth would weighs 84 lbs on Mars.
17) The Martian day is 24 hours
39 minutes and 35 seconds long.
18) The Sun makes a full rotation
