According to National Aeronautics and Space Administration, the coldest place in the universe is the Boomerang Nebula. NASA reported that “at a cosmologically crisp one degree Kelvin,” the Boomerang Nebula takes the title of the coldest place in the known universe.
The Coldest Place on Earth
Researchers studying subatomic particles created a device — called a cryostat — that can create really cold temperatures: An 880-pound (400-kilogram) copper cube reached 6 millikelvins, just six-thousandths of a degree above absolute zero (0 degrees Kelvin) back in 2014.
It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale. The notion that there is an ultimately lowest temperature was suggested by the behaviour of gases at low pressures: it was noted that gases seem to contract indefinitely as temperature decreases.
There is one region in the known universe, the Boomerang Nebula, a cloud of gas that surrounds a dying star in the constellation of Centaurus, which is even colder than the rest of the universe — around 1 Kelvin or minus 457.6 ⁰F (minus 272⁰ C).
It is also known as the Bow Tie Nebula and catalogued as LEDA 3074547. The nebula's temperature is measured at 1 K (−272.15 °C; −457.87 °F) making it the coolest natural place currently known in the Universe. The Boomerang Nebula is believed to be a star system evolving toward the planetary nebula phase.
Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius. Supermassive black holes are even colder. But a black hole's event horizon is incredibly hot. The gas being pulled rapidly into a black hole can reach millions of degrees.
The temperature of space is approximately -456 degrees Celsius. This translates to roughly 2.7 Kelvin. For perspective, the coldest temperature ever recorded on Earth was -138.5 degrees Celsius, or 178.45 Kelvin, in Antarctica.
90 seconds after exposure, you'll die from asphyxiation. It's also very cold in space. You'll eventually freeze solid. Depending on where you are in space, this will take 12-26 hours, but if you're close to a star, you'll be burnt to a crisp instead.
Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops.
Once in space you will eventually freeze, but very slowly as the only way to lose heat in space is by electromagnetic radiation, there being nothing to conduct the heat away. You would die of oxygen starvation long before that happened.
Research on human tolerance to cold has shown that onset of pain occurs at 15°C (59°F) skin temperature (Havenith et al. [10]), numbness occurs at 7°C (44.6°F) (Provins and Morton [11]) and risk of frostbite is risked at 0°C (327) (Havenith et al.
Absolute zero cannot be achieved, although it is possible to reach temperatures close to it through the use of evaporative cooling, cryocoolers, dilution refrigerators, and nuclear adiabatic demagnetization. The use of laser cooling has produced temperatures of less than a billionth of a kelvin.
The temperatures reached in 2012 through the Large Hadron Collider experiment reached a staggering 5 trillion degrees Kelvin / 7.2 trillion degrees Fahrenheit, which is hotter than a supernova. This artificially created temperature still holds even today the biggest record for the hottest thing ever created on Earth.
A supernova is the hottest thing in the universe. The temperatures at the core during an explosion skyrocket up to 6000X the temperature of the sun's core.
Liquid nitrogen is much colder than ice.
Other astronauts have described it in similar yet varying ways: "burning metal," "a distinct odor of ozone, an acrid smell," "walnuts and brake pads," "gunpowder" and even "burnt almond cookie." Much like all wine connoisseurs smell something a bit different in the bottle, astronaut reports differ slightly in their " ...
In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
Water and dissolved gas in the blood forms bubbles in the major veins, which travel throughout the circulatory system and block blood flow. After about one minute circulation effectively stops. The lack of oxygen to the brain renders you unconscious in less than 15 seconds, eventually killing you.
Astronauts need space suits to stay alive. You could only last 15 seconds without a spacesuit - you'd die of asphyxiation or you'll freeze. If there's any air left in your lungs, they will rupture.
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
The outback gets so hot and dry because a high pressure ridge sits over it most of the time. This high pressure ridge is the result of the relationship between the earth and the sun. Because our planet is a sphere, more of the sun's energy is focussed around the equator than at the poles.
The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.
Ice Is Found Throughout Our Solar System
Instead, rocky materials and metals formed the smaller rocky planets. Farther out, beyond the asteroid belt, ices condensed in the colder reaches of space, forming the cores of Jupiter, Saturn, Uranus, and Neptune — the gas giants — and their moons.
