A mysterious cool place hidden in the Milky Way galaxy!
For decades, space scientists have been intensively researching which region of our familiar Milky Way galaxy is very cold and dark. Space scientists have closely observed and studied that the surface of dwarf planet Pluto may be the coldest place in our solar system.
According to them, the average surface temperature of Pluto can be approximately minus - 230 degrees Celsius. In particular, the United States Space Research Organization (NASA) sent a high-tech New Horizons space-probe on January 19, 2006, for the purpose of researching Pluto and its moons, as well as the mysterious Kuiper Belt.
As the New Horizons space-probe planned a close-up flyby of Pluto, its high-tech sensors confirmed its extremely cold surface temperature. However, they believe that dwarf Pluto is not the coolest region of our solar system.
According to the research of scientists, the 'Oort Cloud', considered to be the very last part of our solar system, may be the coldest and darkest region. The 'Oort Cloud' is a vast cold region where water, methane, ethane and many other unknown objects have remained in an extremely freezing state since the formation of the Solar System. Which is still beyond the understanding of scientists.
According to the research of scientists, the average temperature at the very depths of the Oort cloud can be approximately minus - 268 degrees Celsius. Moreover, this region may extend from 2,000 astronomical units (AU) to about 100,000 astronomical units (AU), starting at the end of the Kuiper Belt. Where one astronomical unit (AU) is equal to 149.56 million kilometers.
Although scientists believe that the Oort Cloud is a very cool place, about 100,000 light-years in diameter, it is the coolest region in the Milky Way Galaxy, but not in our Solar System. Instead, they suggest that the Boomerang Nebula may be an incredibly cold spot in the universe. The Boomerang Nebula is a proto-planetary nebula located approximately 5,000 light-years from Earth in the Centaurus constellation.
The average temperature of this mysterious 'boomerang' nebula or nebula region hidden in the Milky Way Galaxy could be approximately 1 Kelvin or minus - 272 degrees Celsius. But it is not the coldest region in the universe. In fact, with the help of powerful telescopes of current technology, scientists have done extensive research and observation and have so far identified this place as an extremely cold or freezing point region.
