New Space facts | Fact about space | our solar system.
The space is completely silent.
There is no atmosphere in space, which means that there is no medium or way of traveling to hear the sound. Astronauts use radio to stay in communication/touch while in space, because radio waves can still be sent and received.
The hottest planet in our solar system is 450 ° C.
Venus is the hottest planet in the solar system and has an average surface temperature of about 450 ° C. Interestingly, Venus is not the closest planet to the Sun - Mercury is close but because Mercury does not have an atmosphere to regulate temperature, it is huge in temperature fluctuations.
There can be life on Mars.
Of all the planets in our solar system (other than Earth), Mars has the most potential for life. In 1986, NASA discovered that they thought a rock recovered from Mars may contain fossils of microscopic living things.
Nobody knows how many stars are there in space.
The sheer size of space makes it impossible to estimate accurately how many stars we have. Right now, scientists and astronomers use the number of stars within our galaxy, the Milky Way, to make estimates. The number is between 200–400 billion stars and is estimated to be billions of galaxies, so the stars in space are actually completely uncountable.
A Full price of NASA's space suit is $ 12,000,000.
While the entire suite costs a cool $ 12m, 70% of that cost is for the backpack and control module.
Neutron stars can rotate 600 times per second.
Neutron stars are the densest and tiniest stars in the known universe and although they have a radius of about 10 km (6 mi), they can be a few times larger than the Sun. They can rotate 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 per second due to their physics.
Diamond planet
As space facts go, this is very impressive. Research by scientists at Yale University suggests that a rocky planet called 55 Canary E - which has twice the radius of the Earth, and a mass eight times larger - may have a surface made of graphite and diamonds. It is 40 light years away but visible to the naked eye in the constellation of Cancer.
Footprints on the moon will last for 100 million years.
The moon has no atmosphere, meaning there is no air to destroy the surface and no water to wash off the footprints. This means that the footprints of Apollo astronauts will remain for millions of years, along with spacecraft prints, rover-prints and discarded material.
The Milky Way and Andromeda galaxies will collide in 4.5 billion years.
The Andromeda Galaxy is approaching the Milky Way - where our solar system is - at a rate of about 110 kilometers per second (68 mi / s) and eventually both will collide to form a giant elliptical galaxy.
If two pieces of the same type of metal touch into space, they will be permanently bonded.
This incredible and unbelievable fact is also known as cold welding and is because atoms of two pieces of metal have no way of knowing that they are different. It is not caused by air and water found between the pieces on Earth.
There is water floating in space.
Astronomers have found a massive water vapor cloud that holds 140 trillion times the Earth's oceans about 10 billion light years away - making it the largest discovery of water ever found.
The moon was a part of Earth in the beginning.
The theory is that when Earth was a relatively young planet, it collided with a giant object and this collision broke a piece of Earth to form the Moon. This piece began to revolve around the Earth as a result of its gravitational pull.
The mass of the Sun accounts for 99.86% of the solar system.
Composed of three quarters of hydrogen and helium for its remaining mass, the Sun is about 330,000 times larger than the Earth with 99.86% mass in our solar system.
Biggest mountain of solar system, 3 times bigger than Everest.
According to scientists, 600 km wide and 21 km high, Olympus Mons is a volcano on Mars that can still be active. It is the highest peak of any planet. However, the Raisilvia central peak on the asteroid Vesta is longer at 22 km.
