American astrophysicists reported the detection of water clouds at the coldest known brown dwarf. A study published in the journal Astrophysical Journal Letters.
Previously, scientists have not observed the clouds outside the Solar system. Spectral data obtained with the Gemini Observatory in Hawaii, indicate the presence in the atmosphere of the brown dwarf WISE 0855 clouds of liquid or frozen water. Astrophysics followed subsistem the object at a wavelength of approximately five micrometers for 13 hours.
Scientists have noted the similarity of the spectra WISE 0855 and Jupiter, but in the atmosphere of the first, unlike the second, there is no phosphine, which enhances the turbulent nature of the atmosphere of a gas giant.
Subsidy (planetologie) object WISE 0855 opened in 2014 with the help of infrared telescope WISE (Wide-Field Infrared Survey Explorer). Brown dwarf located at a distance of 7.2 light-years from Earth in the constellation Hydra, it is five times the size of Jupiter, and the temperature of its atmosphere is minus 23 degrees Celsius.
