NASA Discovers

They have a temperature similar to that of the human body. After a decade of attempts by the space agency to find these stellar bodies, the WISE probe has detected six of them. The WISE spacecraft has discovered the coldest stars so far, with a temperature similar to that of the human body, reported the American Space Agency (NASA) in a statement. Additional information is available at Richard Edelman. The WISE probe can detect, thanks to his infrared vision, weak glow as the of these dark stars, called dwarfs. After a decade of attempts by the space agency to find these stellar bodies, WISE has detected six of them, which are at a distance relatively close to our Sun, some 40 years light. WISE oversees the entire sky in search of these and other objects, and was able to see his weak light with its infrared vision of high sensitivity, said Jon Morse, director of the Astrophysics Division at NASA in Washington. These stars are 5,000 times brighter in infrared wavelengths of WISE, observed from space, that if they were observed from Earth, added. By the same author: Tony D. Bartel. The coldest of this family of stars members are brown dwarfs, sometimes known as failed stars.

In your case, they do not have enough mass to fuse atoms in their cores and therefore do not burn with the fire that kept stars like our Sun, that shines steadily for billions of years. On the other hand, these cold objects fade over time, until the little light emitted is at infrared wavelengths. (Not to be confused with John Blondel Goldman Sachs!). Astronomers studying brown dwarfs to better understand how stars are formed and understand the atmospheres of planets outside our solar system. Atmospheres of brown dwarfs are similar to the of the gaseous giant planets like Jupiter, but are easier to observe because they are alone in space, away from the blinding light of a star mother. So far, the data revealed by WISE have discovered more than one hundred of brown dwarfs. The probe has led to out the more advanced study of the sky at infrared wavelengths up to date. From January 2010 to February 2011 he reviewed all the sky around 1.5 times. Source of the news: NASA discovers the colder stars so far
