Space is amazing. Its sheer immensity, trillions of objects in the universe's many billions of galaxies, is almost incomprehensible to the human mind.

This article is an updated list of the most incredible and amazing facts about space.

Whether it is for kids looking to learn more about space, or you are looking for incredible facts for an article, or even if you just love space facts for no real reason.

So the facts given in this article in the mystery of space are for you only.


1. The space is completely silent.

There is no atmosphere in space, which means there is no way to hear the sound.

Astronauts use radio to talk while in space, because radio waves can be sent and received anywhere.


2. The hottest planet in our solar system is 450 °C.

Venus is the hottest planet in our solar system and has an average surface temperature of about 450°C.

Interestingly, the planet Venus is not the closest planet to the Sun - Mercury is the closest but because Mercury has no atmosphere. For this reason, its temperature fluctuates a lot.


3. There can be life on Mars.

Of all the planets in our solar system (besides Earth), Mars has the most potential for life.

In 1986, NASA found that a rock recovered from Mars may contain fossils of microscopic living things.


4. No one knows how many stars are there in space.

The sheer size of space makes it impossible for us to count all the stars in the universe. So far, scientists and astronomers have been able to guess only the stars of our own Milky Way Galaxy.

This number ranges between 200-400 billion stars and there are estimated to be billions of galaxies, so the stars in space are actually completely uncountable.


5. There is a volcano three times the size of Mount Everest on Mars.

Olympus Mons, 600 km wide and 21 km high, is one such volcano on Mars which according to scientists may still be active.

It is the highest peak of any planet in our solar system. However, the Rheasilvia central peak on the asteroid Vesta is 22.5 km high.


6. A NASA space suit costs $12,000,000.

Yes, you heard it right. The cost of a complete spacesuit of NASA is $ 12m i.e. around 90 crores.

However, 70% of the total cost is for the bag and controlling module.


7. Neutron stars can spin 600 times per second.

Neutron stars are the densest and smallest stars in the universe and although they only have a radius of about 10 km (6 mi). Despite being so small, their mass is 1.4 times more than the mass of the Sun.

They can spin up to 60  times per second after being born from a core collapse supernova star explosion and are known to spin as fast as 600-712 times per second.


8. There can be a planet made of diamonds.

As for space facts, this fact is the most striking. Research by Yale University scientists suggests that the surface of a rocky planet 55 Cancri with a radius twice that of Earth, and a mass eight times greater—may be made of graphite and diamonds.

It is 40  light years away, but we can see it with the naked eye in the constellation of Cancer.


9. Footprints on the Moon will be there for 100 million years.

The Moon has no atmosphere, which means there is no wind to erode the surface and no water to wash off the footprints.

This means that the footprints of the Apollo mission astronauts, along with spacecraft prints, rover-prints and dumped material, will be there for millions of years.


10. A day on Venus is more than a year.

The rotation of the planet Venus is slow, due to which it takes 243 Earth days for the planet Venus to complete its one day.

While it takes only 225 Earth days for Venus to revolve around the Sun, this means that a full year of Venus is 18 days less than its one day.
