There is so much we don’t know about space. And it is not possible anyway to know everything. But that doesn’t mean we should stop exploring it. So here are few shocking yet surprising facts about space you might wanna know.
So let’s get started.
The hottest planet in our solar system is Venus
Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C. Now here the interesting fact is the closest planet to the Sun is Mercury. That’s because of different gases in the atmosphere that create a greenhouse effect which causes a constant temperature of 462° Celsius.
Enceladus, one of Saturn’s smaller moons, reflects 90% of the Sun’s light
That is because Enceladus’ icy surface reflects sunlight rather than absorbing it, temperatures reach as low as -394° Fahrenheit (-201° Celsius).
The first celestial object identified as being spiral was The Whirlpool Galaxy (M51)
The grand, spiraling arms of the Whirlpool Galaxy are made up of long lanes of stars and gas, sprinkled with lots of space dust. These arms act as star formation factories. And it compresses hydrogen gas and creates clusters of new stars.
The space is completely silent
There is nothing known as atmosphere in space, which means sound does not have a proper way to travel in order to be heard. That is why astronauts use radio to communicate while in space, since radio waves can still be sent and received.
The Martian day is 24 hours 39 minutes and 35 seconds long
Now that happens usually because Mars orbits the sun slower than the Earth, there are actually 687 Martian days in a Martian year!
There may be a planet made out of diamonds
Now this one is a bit surprising. Research by the scientists of Yale University suggests that a rocky planet called 55 Cancri e — which has a radius twice Earth’s, and a mass eight times greater – may have a surface made up of diamond and graphite. It’s 40 light years away from here.
The footprints on the Moon will be there for 100 million years
The Moon has no atmosphere, that means there is no wind to wear away the surface and no water to wash the footprints away. This means the footprints of the Apollo astronauts, along with spacecraft prints, rover-prints and discarded material, will be there for millions of years to come.
There is floating water in space
Astronomers found out 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.
