Science always amuses everyone by the facts. Scientists always experiment and discover new things time by time.

Here are 23 science facts which were unknown till 2016 as stated in Science Alert and E-Radio.US.

5. There are strange and metallic sounds coming from the deepest point on Earth's surface, Mariana trench. Scientists currently think that that noise is a new kind of baleen whale call.

6. A revolutionary new type of nuclear fusion machine which was being trialed in Germany really works and it could be the key to clean unlimited energy.

Scientists are trying since long time to find a new planet like earth. Next fact is on that.

7. In the Alpha Centauri star system, there is an Earth-like planet which is 4.2 light-years away. Scientists are already planning a mission to visit this planet.

8. Earth has a second mini-moon orbiting it which is known as a 'quasi-satellite'. It is called 2016 HO3.

As everyone knows, Pluto was removed from the solar system in August 2006. There are eight planets currently.

9. There might be a ninth planet in the Solar System which is not Pluto.

10. First written record demonstrating the laws of friction has been hidden for the past 500 years inside Leonardo da Vinci's "irrelevant scribbles".

11. Most dangerous Zika virus can be spread sexually and it can cause microcephaly in babies.

12. Crows have big ears and they are kind of terrifying.
