YouTube - Six similar celestial body with a temperature of cool stars, just like the human body had been found after astronomers hunting for over a decade. These stars are then called the Y dwarfs.
When viewed using ordinary telescopes, Y dwarfs could barely be seen. But after using the telescope Wide-field Infrared Survey Explorer (WISE) NASA, astronomers finally managed to detect the faint light they are. These stars themselves are relatively close to the Sun.
"WISE move all parts of the sky to find various objects, including stars like this and they managed to detect dim light thanks to a highly sensitive infrared vision," said Jon Morse, NASA Astrophysics Division Director, as quoted from Cosmos Magazine, September 5, 2011.
Y dwarfs, Morse said, was in the neighborhood of our sun. The distance between 9 and 40 light-years away. As an illustration, the closest star to our solar system, Proxima Centauri ie, the distance is about 4 light-years away.
Y dwarfs the stars is a member of the family of the coldest brown dwarf. As is known, brown dwarfs are sometimes referred to as failed stars. Their masses are too low to ignite the atoms in the core of the star so that the fire could not burn like other stars, such as our sun is stable over billions of years.
These objects cool and fade with the passage of time until one day, the light that they emit only infrared wavelengths.
"Finding brown dwarfs near the Sun we are like finding a hidden house in our neighborhood that we do not know before," said Michael Cushing, a member of WISE research team from the Jet Propulsion Laboratory, California. "It is interesting to know that we have neighbors that have not been found," he said.
After the team managed to detect a brown dwarf candidates, they will use the Spitzer Space Telescope is more powerful for filtering. To confirm, they will use telescopes and spectrometers of the most powerful on Earth to separate object light and saw signs of molecular water, methane, and ammonia possibilities that exist.
