At this point in our galaxy there is an object called the Boomerang Nebula, which is known to be the coldest place in the universe. If all this time you thought Pluto is the coldest place, you are wrong! According to scientists' research to date, it turns out that the coldest place in the universe is the Boomerang Nebula.

What is the Boomerang Nebula? What makes it such a cold place? And why are scientists so interested in studying the Boomerang Nebula?

Dying Star

The Boomerang Nebula is a dying star that is actively ejecting clouds of gas and dust. It was first discovered in 1980 by a team of astronauts from Australia using a special large telescope.

The location of this Nebula from Earth itself is quite far, about 5,000 light years from Planet Earth, precisely in the direction of the constellation Centaurus. The name itself was given because when it was first discovered, its shape was curved like a boomerang.

Dying Star Phase

The Boomerang Nebula is actually not a strange phenomenon. This cloud of dust and gas is the phase of a dying star. The nebula cloud phenomenon only lasts for a few tens of thousands of years. On the scale of the universe, time is short.

The coldest place in the universe

As I mentioned earlier that nebulae are natural phenomena. A surprising thing happened in the 1990s. A group of scientists from various countries was observing this strangely shaped nebula. From these observations it was found that the temperature of the Boomerang Nebula is very cold, even colder than the temperature of the universe.

The average temperature of outer space is -270 degrees Celsius and the temperature of the Nebula itself is -272 degrees Celsius. There are even parts of the nebula where the temperature is 0 degrees Kelvin which means absolute zero, there is no lower temperature measurement.

Why is the Boomerang Nebula Cold?

Now the question is, what causes the Nebula's temperature to be that cold? There is a scientific explanation for this one phenomenon.

The Boomerang Nebula is a collection of gases. As the gas expands, fewer molecules move in it. This is what causes the temperature to be very cold.

The Boomerang Nebula itself is getting bigger and bigger. The ejected gas has had a speed of 164 km/s over the last 1500 years. This movement is 10 times faster than similar objects in space. That is, the larger the size, the colder the temperature. This is what makes the hot temperature of the universe even more difficult to enter.

The shape is always changing

The Boomerang Nebula is named after its shape, which is similar to a boomerang. But the longer we observe, the shape of this Nebula is always changing.

In the late 90s, a group of researchers observed the nebula with the Hubble telescope. It was then discovered that it looked like a misty ribbon tie. This form of nebula is very common because it is caused by spewed gas.

Observations in 2013 were made using the ALMA radio telescope in Chile. The shape becomes like a round cloud surrounded by dust and gas. The band-bond structure looks like a distortion of light, no longer a gas cloud.

Why Are Scientists So Interested In Studying It?

The Boomerang Nebula is a phenomenon that only lasts for a few tens of thousands of years. Quite short for the size of the universe. This is why scientists are so interested in studying it.

Another goal is to find out how the process of death of a star. This is very important to study because in a few billion years, the Sun will turn into a very cold gas giant nebula as well.


Well, so we can conclude that it is true that this Nebula is the coldest place in the universe. So it's not Pluto.

The universe is full of mysteries and surprising unique phenomena. Scientists continue to explore what is in this universe by making continuous observations. What do you think is the benefit of studying the death process of stars like this Nebula?
