Amazing facts you did not know about space

Weather of Arabia - There are many facts and information about space, our solar system and the galaxy that we do not know yet!

Space is vast, with billions of galaxies, stars and planets in our solar system yet to be fully explored or understood. Scientists' knowledge of space is always evolving out there, however we have collected some amazing and fascinating facts about space.

Space is completely devoid of sounds

There is no atmosphere in space, which means that sound has no medium or way to travel in order to be heard.

The hottest planet in our solar system reaches a temperature of 450 degrees Celsius.

The hottest planet in the solar system is Venus, with an average surface temperature of about 450 degrees Celsius.

Did you know that Venus is not the planet closest to the sun? The closest planet is Mercury, so some may think that Mercury is the hottest because of its proximity to the sun, but it does not have an atmosphere (temperature regulation), which leads to large fluctuations in temperature.

The price of a complete NASA spacesuit is $12 million

However, 70% of that cost goes to the rear bag and console. However, the spacesuits used by NASA were built in 1974. If the price of these suits were set at current prices, they would cost about $150 million!

Sunsets on Mars appear blue

Sunsets on Mars, according to the US space agency, appear blue to human observers watching from the Red Planet.

Fine dust makes the blue color near the part of the sky closest to the Sun more visible, while the natural red light of day makes the rusty dust color common on the Red Planet more visible to the human eye.

There are more stars in space than there are grains of sand on Earth

The universe extends far beyond our galaxy, the Milky Way, which is why scientists can't accurately estimate the number of stars in space. However, scientists estimate that the universe contains about 1,000,000,000,000,000,000,000,000 stars, or septillions. While no one can actually count every grain of sand on Earth, the estimated total from researchers at the University of Hawaii is about seven quintillion five hundred quadrillion grains of sand.

A day on Venus is longer than a year on Earth

The axis of Venus rotates slowly, and its daily cycle takes 243 days on Earth to complete its day, and the orbit of Venus around the sun takes 225 days on Earth, which makes a day on Venus more than a year on Earth
