The coldest temperatures of deep space are extremely frigid and far below anything encountered on Earth. According to current research, the temperature in space dips down to an average of -455°F, with temperatures as low as -460°F even recorded in some areas.
These extremely low temperatures occur due to the fact that in deep space there is no external heat source and the only heat available is generated by the heat of subatomic particles. This heat, however, is not enough to create even a remotely livable temperature.
Of course, temperatures vary based on a number of variables, with some pockets of space offering slightly higher or lower temperatures than the average.

How cold is the coldest place in space?
The coldest place in space is the Boomerang Nebula which is located 5,000 light-years away in the constellation Centaurus. This nebula is estimated to have a temperature of -272. 15°C, which is only 1 degree Celsius above absolute zero—the coldest temperature theoretically possible.
This temperature is about three times colder than the coldest temperature ever recorded on Earth. While the previous record was -89. 2°C, the Boomerang Nebula reaches ultra-low temperatures due to its extreme distance from Earth, its rapid rotation, and its extremely thin dust clouds that allow it to radiate large amounts of energy into the vacuum of space.
In addition to its incredible temperature, it has also been found to be a record holder for fading the fastest optically discovered object.
Is there anything colder than space?
Yes, there are a few things colder than space. For example, in 2018, a team of scientists studying Saturn’s moon Enceladus found a cavernous region of space that had the coldest temperature ever measured in the solar system, at -328 degrees Fahrenheit (-200 degrees Celsius).
Another example is in 2016, an atomic cloud located nearly 11,000 light-years away from Earth was measured at minus 458 degrees Fahrenheit (-272 degrees Celsius), making it the coldest natural object ever observed in the universe.
In addition, there have been reports of temperature in the realm of supersolids, or normal matter at absolute zero, which is the coldest temperature theoretically possible at -459. 67 degrees Fahrenheit (-273.
15 degrees Celsius).
What does space smell like?
The answer to what space smells like is surprisingly varied depending on who you ask. Astronauts have reported it to have the odour of seared steak, hot metal, welding, and even gunpowder. Some have even described the smell of burning or air that has been superheated by the sun.
These scents may reach the astronauts’ olfactory senses when they do spacewalks. Others believe that it may be caused by polycyclic aromatic hydrocarbons (PAHs) which are molecules containing both nitrogen and carbon, molecules common on meteorites and in interstellar gas and dust.
Some researchers think that the smell is caused by charged particles in the solar wind mixing with Earth’s magnetic field, while others believe that these particles help create ozone. One theory suggests that when cosmic particles interact with the Earth’s upper atmosphere, they help create a distinctive smell as they are broken down.
Whatever the cause, it is clear that there is some kind of odour associated with space, whether NASA officially recognises it or not.
How cold is absolute zero?
Absolute zero is the temperature of -273. 15°C (-459. 67°F). It is the lowest temperature that can be achieved, and is an extreme cold that cannot be experienced with everyday materials. This temperature is believed to be the point where molecular activity stops, where atoms and molecules have no more kinetic energy and theoretically can’t move.
At this point, matter doesn’t possess any thermal energy and has no temperature above absolute zero. It is not possible to attain absolute zero in the laboratory, but extremely low temperatures of several millikelvins (one-thousandth of a kelvin) are possible to reach.
How is it cold in space but hot on earth?
Even though space seems like an empty void, its temperature can vary greatly! The temperature of space can range from close to absolute zero (-459F) to extremely hot (3,000F). Space is so cold because it is a vacuum and there is no atmosphere to hold in heat.
Additionally, the lack of air prevents heat from radiating in all directions, so it’s harder for heat to stay in the environment. On Earth, we have an atmosphere composed of gases like nitrogen and oxygen that can hold in heat and act as an insulator.
Additionally, the Sun’s light and heat is able to reach us and warm up the surface. Earth’s atmosphere is also able to deflect some of the intense radiation from the Sun, which helps keep the surface from getting too hot.
So while space may be extremely cold, the atmosphere on Earth is able to provide insulation and protection against the cold temperatures of space.
Why is the sun hot but space cold?
The sun is incredibly hot because it’s an incredibly large and dense source of energy that emits light and heat. Even though it’s 93 million miles away from Earth, it’s still the closest star to us and its enormous mass contributes to intense gravitational forces.
This massive gravitational force compresses the core of the sun and creates extreme temperatures up to 27 million degrees Fahrenheit.
Space, on the other hand, is incredibly cold because it is a vacuum and does not have an atmosphere to trap or create heat. The average temperature of space is estimated to be around minus 455 degrees Fahrenheit.
This is due to the fact that space is incredibly far away from the nearest star, so there is no source of heat and light; there are no molecules to absorb and release energy, and because of this, there is no way for objects to gain or lose heat except for through radiation.
Space also does not have an atmosphere to help insulate things and reflect energy, so there is nothing to contain the warmth or spread it around.
How cold would space be without the sun?
Space is a vacuum, meaning it contains no air and so no molecules to carry heat, meaning space is already an incredibly cold environment. Without the sun, the average temperature of space would drop to absolute zero – the coldest temperature any gas, liquid, or solid can reach – at a frightening -459.
67°F (-273. 15°C). This is because the average temperature of space is determined by how much energy it receives from its surroundings. Without the warmth and energy provided by the sun, space would be an incredibly cold and unforgiving environment for any living thing.
Can you survive in space for 30 seconds?
It is possible to survive in space for 30 seconds, although it would be a very challenging task. Without the protective cover of a spacecraft or a pressurized suit, a human would most likely expire after only seconds due to lack of pressure and oxygen.
However, in theory, it would be possible to survive in space for 30 seconds or more if the person had some sort of pressurized suit or oxygen supply and was in an environment that was not exposed to the harsh vacuum of space.
In such an environment, the person would be able to breathe in the air, and even if the person couldn’t move in zero gravity, they would not be exposed to the vacuum. They would also need to be protected from extreme cold and the Sun’s radiation.
With all these factors in place, it is possible for a human to survive in space for up to 30 seconds.
Would your blood boil in space?
No, your blood would not boil in space as it would in Earth’s atmosphere or in other atmospheres with significant air pressure. Space is a vacuum, meaning that it has very low air pressure which results in a lack of air molecules around an object, including a human body.
Without air molecules the air cannot be heated, which means that the boiling point of the blood is not reached. However, other physical conditions in space would still prove to be very dangerous and potentially deadly for a human body.
For example, extreme temperatures in space, lack of oxygen and water, and the high dose of solar radiation can kill a person in a matter of minutes outside the Earth’s atmosphere.
How cold is space void?
Space is incredibly cold, often reaching 2. 7 degrees Kelvin, which is -270 degrees Celsius or -455 degrees Fahrenheit. Because space is a vacuum with no atmosphere, there is no way for heat to be transferred from one area to another.
This lack of atmosphere also means that there is no buffer from the extreme temperatures of the sun or other star systems. Space is essentially a giant, void of near absolute zero temperatures. As you can imagine, the temperature of space does vary, but overall exists at an incredibly chilly temperature.
When water freezes Does it shrink and take up less space?
Yes, water does shrink and take up less space when it freezes. This is due to the fact that when water is in its liquid form it is made up of molecules. As these molecules freeze and turn into solid form, the structure of molecules forces the water molecules to arrange themselves in a way that makes the water take up less total volume than it did when it was in liquid form.
This is why ice cubes are smaller than the same amount of water that was used to make them before it was frozen. As the water freezes, it takes up less space, therefore causing it to shrink.
Does ice stay frozen in space?
Yes, ice can stay frozen in space. This is because space does not have an atmosphere and the temperature is so low that anything that does not absorb radiation will reach near absolute zero temperatures (-459.
67 degrees Fahrenheit). The extreme cold in space can freeze any substance, including water and other liquids, and even gas molecules if they are not exposed to the energy released by stars. Additionally, because space is a vacuum, there is no water vapor to cause the ice to melt, so the ice will stay frozen until the temperature is increased sufficiently by external energy sources.
Is there frozen water in space?
Yes, there is frozen water in space. Out in our Solar System, frozen water can be found on many of the moons and on the icy surfaces of dwarf planets such as Pluto and Eris. Water ice has also been found on the surfaces of some asteroids, comets, and even passing near Earth in the form of interplanetary dust particles.
Additionally, many suspected clouds of frozen water can be found throughout space. Some of the most notable frozen water clouds are the rings of Saturn, the outer regions of the Kuiper Belt, and the Oort Cloud which lies far beyond over 1,000 AU from the Sun.
The extreme cold temperatures of much of space, ranging from -450°F to -270°F (-268°C to -168°C), make it an ideal place for water to freeze, even without an atmosphere.
