Coldest Place in the Universe -Boomerang Nebula
The coldest place in the universe is an object called a Boomerang Nebula — think of it as a blazing, spinning star caught on camera. How does it work? Let’s break it down for you. A Boomerang Nebula is so named because its shape resembles that of a boomerang — what’s interesting about that? It’s spinning at such a speed (700,000 miles per hour) that it’s actually pulling material away from itself! This phenomenon only happens to white dwarf stars and they are so hot, they’re blue or white-hot. If you could get close enough to one to see them with your own eyes, like Hubble did here, they would shine almost 10 times brighter than Venus appears in our sky!
Boomerang Nebula -the coldest place
According to Guinness World Records, aside from laboratory-created temperatures, “the coldest place in the universe is the Boomerang Nebula, a cloud of dust and gas 5,000 light-years from Earth.” In 1995, astronomers Sahai and Nicholas Mann’s use of the Swedish submillimeter telescope 15 meters away in Chile shows that the Boomerang Nebula is the coldest place in the universe ever discovered. Bill Saxton / NRAO / AUI / NSF / NASA / Hubble / Raghvendra Sahai “The coldest place in the universe” Reveals his true form with ALMA. The rapid expansion of the Boomerang Nebula makes it the coldest known region in the universe.
The Boomerang Nebula in the southern hemisphere constellation Centauri is considered one of the coldest places in the known universe. This frigid region of the Boomerang Nebula was discovered by astronomers in 1995 using data from the Swedish-European submillimeter radio telescope at the La Silla Space Observatory in Chile. According to Hubble astronomers, the coldest place is the Boomerang Nebula. Dying Star.
The Boomerang Nebula, a mixture of interstellar dust and ionized gas, is dropping to a staggering minus 458 degrees Fahrenheit (minus 272 degrees Celsius), or just 1 degree Celsius above absolute zero, as astronomers measure using the Atacama. Submillimeter Array (ALMA) in Chile in 2013. Our cycle 0 ALMA observations confirm that the Boomerang Nebula is the coldest known object in the universe, and its massive high-velocity outflow has cooled significantly below the cosmic background.
According to the Universe today, the result is that we see the boomerang during a brief moment of cosmic maximum cooling. Normally, the slow expansion of a protoplanetary nebula would not cause the boomerang to be very cold, but measurements suggest that the boomerang is expanding much faster than usual.
It is this rapidly expanding gas that gives the nebula its lethal temperature. It seems that the very rapid expansion of the gases is what makes the nebula so cold.
According to astronomer Ragvendra Sahai, the extreme cold is caused by the rapid acceleration, ejection and …………..
