How Cold Is The outer Space Really?


How Cold Is The outer Space Really?

The space is cold. Really cold. It will freeze your eyeballs off and suck them into oblivion. But do you know why? It's because of light! When light passes through a vacuum, it actually loses energy by emitting infrared photons in all directions. This is why you often see stars twinkle and planets appear to shimmer when viewed from our Earthly vantage point; both are manifestations of starlight being scattered as it passes through our atmosphere. The space around us is also filled with cosmic dust — small particles of rock and minerals — that reflect some of that starlight back to our eyes!

The coldest temperature ever recorded in our solar system was on February 27, 2010, when Voyager 1 flew by Neptune. The spacecraft was only 471 million kilometers from the planet at that time. In terms of frigid-cold, this is equivalent to crossing the Atlantic Ocean from Spain to France.

How cold is it in outer space?

The temperature of outer space is very cold, but not as cold as you might think. It depends on what altitude you are at and how far away you are from the Sun.

The temperature of outer space is around -270 degrees Fahrenheit (-195 degrees Celsius). This is because there is no atmosphere to heat up things up, so they stay at their original temperature. The Sun's rays also don't warm things up much, either.

If you were to take a thermometer into space, it would read -270 degrees F (-195 C). This may seem extremely cold to us here on Earth, but for us humans it is actually pretty mild!

The temperature of the planets in space:

The temperature of the planets in space depends on their distance from the sun. The Earth, being closer, is hotter than Venus and Mars and cooler than Mercury.

Mercury is so close to the sun that it is boiling hot and its surface temperature is 480 degrees Fahrenheit (250 degrees Celsius).

Venus has a scorching atmosphere with a surface temperature of 860 degrees Fahrenheit (460 degrees Celsius), making it the hottest planet in our solar system.

Mars has an atmosphere but no landmass, so it's very cold there. It gets down as low as -148 degrees Fahrenheit (-89 degrees Celsius).

The average temperatures at different orbits around the sun:

Mercury: -208°C (-321°F)

Venus: -117°C (-188°F)

Earth: -18°C (0°F)

Mars: -63°C (145°F)

Jupiter: -167°C (320°F)

Saturn: -177°C (359°F)

Uranus: -268°C (520°F)

What's the coldest temperature in space?

The coldest temperature ever measured in space was -273.15 degrees Celsius. This was measured by an American team of scientists using a satellite called COBE (Cosmic Background Explorer). The satellite launched in 1989 and became active in 1992, measuring the microwave background radiation from the big bang.

The COBE satellite detected a temperature of about -270 degrees Celsius, which is cooler than any place on Earth. It also showed that the universe had a very uniform temperature of about 3 Kelvin when it was young, only 380,000 years old.

How do astronauts survive the cold in space?

How do astronauts survive the cold in space?

The first thing to know is that astronauts experience lower temperatures on the Moon than they do on Earth. This is because, on the moon, there is no air pressure to insulate them from the cold. The moon's surface temperature can range from minus 100 degrees Celsius (minus 148 degrees Fahrenheit) during lunar night to up to plus 50 degrees Celsius (plus 122 degrees Fahrenheit) during lunar day.

The second thing to know is that a spacesuit will keep an astronaut warm even if the temperature outside is extremely cold. A spacesuit has insulation layers that trap heat and block out any wind flowing in from outside. Plus, spacesuits are designed with a layer of reflective fabric called an ablative heat shield between its outer covering and its inner lining. This reflective layer reflects infrared radiation back into outer space, which helps keep astronauts warm inside their suits even when it's cold outside.

NASA astronauts on the International Space Station are protected against the cold of orbit by their spacesuits. These suits are made of a lightweight plastic and thermal insulation, with layers of cloth to provide better air circulation. They are designed to be worn for long periods of time in low humidity, so they can keep you comfortable even in extreme conditions.


There's one more thing you should know about temperature and space travel. The farther out you go, the colder it gets. In fact, at a distance of 100,000 miles from Earth, a trip to the Moon feels like an icy -300 degrees Fahrenheit—and it keeps getting colder from there. Only a handful of human beings have been that far out. And for those few astronauts and cosmonauts who have ventured beyond our earthly borders, a phenomenon called radiation poses an even greater threat than frostbite.

As it turns out, space is pretty frigid. So frigid, in fact, that if you were to take your body out there without a spacesuit on, you would freeze to death. No exceptions. This was evidently not considered during the filming of the original Alien movie.
