No sound can travel through space
Since there is no air in space, so no medium is present in space to assist in the traveling of sound waves. Radio waves in comparison to sound waves can travel through space and can be received or sent. Moreover, astronauts use radio waves to keep in touch and communicate.
Planets that revolve around stars other than the sun
We all know that planets in our solar system revolve around the sun. But are there planets in space that orbit other stars other than our sun? So, yes, NASA has discovered many planets that orbit other stars in other solar systems. Such planets are called exoplanets.
The first soft-drink to be consumed in space was Coca-Cola
Have you ever wondered about a soft-drink that got the privilege out of many soft-drinks to be consumed ever in space? Well, Coca-Cola is reported as the first commercial soft-drink to be consumed by astronauts while their journey through space.
Milky way-The home of many stars
Out of many galaxies found out, Milky Way is the only galaxy that is home to many stars. According to an estimate, there are more than 100 thousand million stars in our galaxy-the Milky Way as compared to other known galaxies.
Planets with no moons
There are reportedly 176 moons that orbit different planets within our solar system. But do all planets have moons? Interestingly, no. There are 2 planets within our solar system that have no moons. An example of them is Mercury and Venus.
The size of Pluto is smaller than earth and even smaller than the United States
Well, it is true. The diameter of the United States is 4650 km while that of Pluto is 2374 km.
The footprints on the moon don’t erode
As the moon has no wind or atmosphere, thereby there is no substance to erode or wash away the footprints that are there for many years. Interestingly, then we can predict that the moon will have records of footprints that are more than 100 million years old.
The highest Mountain
The highest mountain is not located on earth but on mars. Olympus Mons is the highest known mountain found on Mars with height 3 times more than Mount Everest and width more than that of Arizona.
A Planet Made of diamonds
Interestingly, scientists have found a planet in space that is made of diamonds. The planet has mass 8 times larger of Earth’s. If we want to move there, then we have to travel a distance of 40 light-years. The planet is called 55 Cancri e.
Water in space?
Have you ever wondered about the presence of water in space? Recently, scientists have found out a massive cloud containing water vapors floating in space. This is the largest reserve of water ever discovered in space which is 10 billion light-years away from us. Moreover, the cloud holds water about 140 trillion times more than the mass of water present in Earth’s oceans.
A planet that can float in water
Have you ever wondered about a planet that could even float in water? Well, surprisingly, scientists have found a planet that can even move or float in water. Shockingly, Saturn which is the second-largest planet among all the planets in our solar system is the lightest of all planets. Saturn is mostly made of different gases and holds the capacity to move in the water. But off-course, we need a giant tub full of water to make that happen.
How much portion of the universe can we see with our naked eye?
The portion of the universe that we are seeing from our naked eye is less than 5%. According to an estimate, the universe is 68% dark energy and 27% dark matter. We cannot see dark energy or dark matter with our visible eye. They are even not visible without a telescope. So, the only visible portion of the universe that we can visualize is 5%
Within a period of 3.75 billion years, our galaxy will collide with another galaxy
Another galaxy named as Andromeda Galaxy is moving and approaching close to our galaxy-the milky way. Moreover, the Andromeda galaxy is closest to our galaxy. It is estimated that within a period of 3.75 billion years, our galaxy will collide with the Andromeda galaxy. Expectedly, because of the collision, the two galaxies will combine and will give rise to another big elliptical galaxy.
From where the moon came from?
Interestingly, Moon was once a portion of the earth. Billions of years ago, when the earth was struck by a giant object, a portion of earth broke away forming the moon. The broken portion got attracted to the earth by its gravitational pull and later was called a moon.
The height of a person can grow in space
If you are interested in increasing your height, you can go to space. Reportedly, astronomers can increase their height to more than 2 inches while in space.
