Although sci-fi movies may lead us to believe that the environment is too cold – even colder – the area is not complex and has no temperature.

Temperature measures the speed at which particles move and the temperature at which the particles of an object are powerful. So in an actual space, there would be no particles and rays, which means there is also no temperature.

Of course, space is full of particles and rays to produce heat and temperature. So how cold is the space, is there an empty region, and is there a point where the temperature drops to zero?

HOW THE STARS HIT THE SPACE

The hottest spaceships are near the stars, which contain all the conditions for initiating a nuclear war.

Things get hot when the star’s rays reach space with many particles, and this gives the glow from the stars like the sun something to work on.

That is why the Earth is hotter than the space between our planet and its star. Heat emanates from particles in our atmosphere that vibrate with the sun’s energy and then collide with each other to distribute this energy.

Being close to our star and having particles is not a guarantee of warmth, though. Mercury – close to the sun – is very hot during the day and very cold at night. Its temperature drops to 95 Kelvins (-288 ⁰Fahrenheit / -178 ⁰Celsius).

The temperature dropped to 371 ⁰F (-224 ⁰C) at Uranus, making it even more relaxed than Neptune’s solar system, with a staggering 353 ⁰F (-214 ⁰C).

This is the result of a collision with an Earth-sized object at the beginning of its existence that causes Uranus to orbit the sun on a massive slope, making it unable to withstand its internal heat.

Far from the star, particles are so widespread that heat transfer through anything other than radiation is impossible, which means that temperatures drop dramatically. This region is called the interstellar medium.

Cold cell clouds that are very cold and very dense between stars can have a temperature of 10 K (-505 ⁰F / -263 ⁰C or), while lightly thick clouds can have a temperature of up to 100 K (-279 ⁰F / -173 ⁰C).

WHAT CAN HAPPEN IF YOU ARE SHOWN IN TIME?

If the astronaut was left to fend for himself in space, exposure to the area near the vacuum could not stop the astronaut, as often portrayed in science fiction.

There are three modes of heat transfer, transfer, which occurs by touch, fluctuations in fluid transfer, and radiation.

Conduction and convection will not occur in a vacuum due to a lack of matter, and heat transfer occurs slowly through radiation processes alone. This means that heat does not transfer rapidly into space.

Since cold requires heat transfer, the exposed astronaut – the heat loss through radiation processes alone – could die from a lack of atmosphere much faster than the ice.
