“After about 14 billion years of cooling off, the space between stars in the universe is very cold,” Worthey said. To find out just how cold, I visited my friend Matthew McCluskey. He’s a professor of physics at WSU who studies all kinds of matter. “Often, we think of ‘space’ as being far from any stars.

When scientists talk about 2.725 Kelvin as the temperature in space, they’re talking about an average temperature — actually, what is called the cosmic background radiation, which is the energy still left over from the Big Bang.

Best Answer: The temperature in the deepest, darkest regions of space is 2.725 kelvin, or -454.765 fahrenheit. This is because of the Cosmic Microwave Background, which is the name given to the background radiation that permeates all of space. It is frickin' cold out there! Yes, it would be really cold.

Outer space is usually considered to be the portion of the universe that is almost entirely empty and, from the point of view of Earth, officially begins at an altitude of about 62 miles (100 kilometers) above sea level.

Room temperature is about 25 degrees Celsius. When matter reaches a temperature of “absolute zero,” it means that molecules have stopped jiggling altogether. Outer space is only about 3 degrees Celsius warmer than absolute zero. So, space is about 295 degrees colder than room temperature.

Closer to Earth, such as just outside of Pluto’s orbit, the temperature is estimated to be closer to 35 or 40 Kelvin due to the effects of the distant Sun. This is still very cold, but nowhere near as cold as somewhere in deep space, far from any sunlight.

That’s about 298 degrees above what scientists call “absolute zero.”. When matter reaches a temperature of “absolute zero,” it means that molecules have stopped jiggling altogether. Outer space is only about 3 degrees Celsius warmer than absolute zero. So, space is about 295 degrees colder than room temperature. Just thinking about it sends a shiver down my spine and all the way to my tail.

In the void between planets, star systems and galaxies, the temperature in space is generally considered to be 2.725 Kelvin which is -454.72°F (-270.4°C). This is only a very small amount above absolute zero, the lowest temperature at which the movement of matter is believed to cease, at -459.67°F (-273.15°C).

It is very cold in space, but it wasn’t always that way. That’s what I learned from my friend Guy Worthey, a professor of astronomy here at Washington State University.
