In mid-2017, it is believed that the star at the center of the nebula is a dying red giant. In 1995, using the 15-metre Swedish-ESO Submillimetre Telescope in Chile, astronomers revealed that it is the coldest place in the Universe found so far, besides laboratory-created temperatures. Red filter applied to monochromatic 2013 ALMA data, For the Bow-Tie Nebula (C2) in Cepheus, see, coolest natural place currently known in the Universe, "ALMA reveals ghostly shape of 'coldest place in the universe, "The Coldest Place in the Universe: Probing the Ultra-Cold Outflow and Dusty Disk in the Boomerang Nebula", https://www.youtube.com/watch?v=k_23xgB5zHM&t=22s. This cold temperature is mostly due to the presence of ammonia and ammonium hydrosulfide in its atmosphere. The outflowing gas is moving outwards at a speed of about 164 km/s and expanding rapidly as it moves out into space; this gas expansion results in the nebula's unusually low temperature. [5] [6], Boomerang Nebula as seen by ALMA in 2017.[7]. The nebula's outer fringes appear to be gradually warming. Moments later, it “cooled down” to 1,800,000,000ºF (1 billion ºC) when the universe was less than two minutes old. 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. It is also known as the Bow Tie Nebula and catalogued as Image Courtesy: NASA Surface Temperature:165 Kelvin We all know that Jupiter is the largest planet in our solar system, it’s a gas giant with mass 1/1000 of the Sun, but it also has one of the coldest temperatures among the discovered planets. Unable to view it with great clarity, the astronomers saw merely a slight asymmetry in the nebula's lobes suggesting a curved shape like a boomerang. Even the −270 °C background glow from the Big Bang is warmer than the nebula. It continues to form and develop due to the outflow of gas from its core where a star in its late stage life sheds mass and emits starlight illuminating dust in the nebula. The Boomerang Nebula is believed to be a star system evolving toward the planetary nebula phase.

The Boomerang Nebula - The Coolest Place in the Universe? Researchers Discover A Planet Exactly Where ‘Vulcan’ Was Predicted To Exist In Star Trek, First Type Of Molecule Ever Formed In The Universe, Scientists Observe Matter Falling Into Black Hole At 30% Light Speed, What is Orion Constellation? The vortex, also known as “Great Cold Spot” is 12,000 km wid… This Hubble image was recorded using polarizing filters (analogous to polarized sunglasses) and color-coded by the angle associated with the polarized light. Coldest Planet In The Universe • What is the most dangerous planet in the universe?----------Our purpose is the importance of education in our society. Astronomers say the Boomerang Nebula is the coldest place in the universe at one degree Kelvin (minus 458 degrees Fahrenheit). The Boomerang Nebula is a protoplanetary nebula located 5,000 light-years away from Earth in the constellation Centaurus. Millimeter scale dust grains mask portions of the nebula's center so most escaping visible light is in two opposing lobes forming a distinctive hourglass shape as viewed from Earth. ----- Our purpose is the importance of education in our society. Facts and Myths. With a temperature of −272 °C, it is only 1 °C warmer than absolute zero (the lowest limit for all temperatures). On the other end of the spectrum, the coolest natural place currently known in the universe is the Boomerang Nebula at -457.6ºF (-272ºC). Keith Taylor and Mike Scarrott called it the "Boomerang Nebula" in 1980 after observing it with the Anglo-Australian telescope at the Siding Spring Observatory. In 2013, observations of the ALMA radio interferometer revealed other features of the Boomerang Nebula. What is the Coldest Planet of Our Solar System? Orbit and Distance: With an average distance (semi-major axis) of 4,504,450,000 km (2,798,935,466.87 mi or 30.11 AU), Neptune is the farthest planet ... Average Temperature: Temperature Anomalies: The Boomerang Nebula is a protoplanetary nebula[2] located 5,000 light-years away from Earth in the constellation Centaurus. It's even colder than background space. The Coldest Place in the Universe Physicists in Massachusetts come to grips with the lowest possible temperature: absolute zero. LEDA 3074547. The nebula was photographed in detail by the Hubble Space Telescope in 1998 revealing a more symmetric hourglass shape. [4] The visible double lobe of the Boomerang Nebula was observed to be surrounded by a larger spherical volume of cold gas seen only in sub-millimeter radio wavelengths. It is the only object found so far that has a temperature lower than the background radiation.[3]. 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.[3].
