10 Extraordinary, Surprising and Amazing Facts about the Universe and Space that will Blow Your Mind

• In 2016, Scientists found a Radio Signal from a Source 5 billion light years away from Earth

Yes, Scientists found that Radio Wave signal 5 billion light years away from earth, which means when the signal was being transmitted, Earth itself didn't exist because it take 5 billion years to reach the light from that part of the universe to the Earth, So it's obvious that it was transmitted before 5 billion year and before Earth formed, it's quite interesting because the signal might be transmitting by someone or something...

• We are Looking into Past almost Every Time

Actually, It's true... Whatever you can see is because light rays are striking to your eyes from the object you are looking at, due to light has some speed so it take some time to reach your eyes from the object. for e.g. It takes 8 minutes 34 seconds to light to reach Earth from the Sun, so the sun we are looking at is from past 8 min 34 sec, if suddenly sun will blast off, we can see it's blast after 8 min, another example is when you see yourself in mirror, you are looking at yourself from past 10 nano seconds because it takes approx 10 nano sec to light to reach your eyes from the mirror..

• Scientists are Successfully Growing Plants in Space

Space is an environment which is not suitable for growing plants, Yes but Scientist are growing plants in ISS by giving it a habitable environment and the project named as Veggie. It takes lots of light to grow a plant with proper strength in the absence of gravity or in micro gravity with the help of LEDs.

• Mercury has only 1.5 days in a Year and Venus has 2 days in a Year

It's quite Curious to know, but it's quite obvious also because Mercury and Venus are the closest Planets to Sun, and, have such a slow rotation around it's axis that it takes 1,5 rotation (days) and approx 2 rotation (days) in a complete revolution (year) around the sun for Mercury and Venus respectively...

• Scientists Discover an Star older than the Universe itself

Hubble Space Telescope found the Methuselah Star, technically HD 140283, is being predicted 14.5 billion years old where as the Universe itself is 13.8 billion years old, It is such a mind blowing and amazing thought that a star can exist before the Universe...

• The Size/Diameter of Pluto is far less than Australia

When I saw this image, it surprises me the most, Many of us might be thinking many times that why Pluto is not in the category of planets now, and the reason is, its size as well as its orbiting position, Pluto is smaller than the size of Austrailia...

• Jupiter is saving Earth from Asteroids since millions of Years

Jupiter is the largest and heaviest object other than the Sun in our Solar System, Thousands of Asteroids are orbiting around the Sun, which can strike to earth but Jupiter's gravity doesn't allowed them to come towards Earth, hundred's of Asteroids are struck in Jupiter's L4 and L5 Lagrange Point, whoever don't know the concept of lagrange orbit or point click here to know, and prefer the image and the animation to understand the concept...

• No Planet is Orbiting the Sun in our Solar System

Actually, Planets as well as Sun are orbiting a point in space called Bary Center, which can be define as the point in space where the center of mass of two or more object orbiting each other. The mass of all the planets are negligible in front of Sun, and the position of orbiting the every object in the solar system is in such a way, So that the barycenter of the sun and the planets are in the sun's radius, so the Sun itself is orbiting the point which is located inside itself...

• It can take 100,000 Years to get a Photon from Core of the Sun to its Surface

when a atom releases a Photon in core of the sun, it scatter photon to a random direction and the reaction is going continuously at very high speed, it simply strike it in random direction continuously and you can imagine how fast it will be so that it takes tens of thousand year to come out from core to the surface of the sun...

• We can never look at the Far Side of Moon even it is Orbiting the Earth

Do you ever notice that the image of Moon we see in the night sky are always of the same side of Moon, this is because the duration of one rotation of Moon or 1 day of moon is equal to the duration of it's Revolution around the Earth. So, it rotates in such a synchronous way with it's revolution around the Earth, so that we are only able to see it's one side...
