Astronomers through NASA’s Hubble Space Telescope were anticipating for any signs of water vapors in three planets but in vain.
These three planets are recognized as HD 189733b, HD 209458b, and WASP-12b, have an extremely high temperature because of which scientists were hopeful to discover few water vapors in their atmosphere. Scientists have recorded temperature of these planets which is almost 1,500 and 4,000 degrees Fahrenheit. These planets have only one-tenth amount of water as compare to the quantity expected by the researchers. Therefore, they are really shocked by this discovery.
According to, Nikku Madhusudhan of the Institute of Astronomy at the University of Cambridge, England, this result of experiments compel researchers to revise their models of the configuration of planets, particularly of hot Jupiter. These experiments provide an insight into how space telescope are supposed to be designed for the planets which are drier than the expectation of scientists.
He also gave reasons behind the selection of these three planets. He said that they chose them since they are comparatively bright stars which offer enough radiation to take inside an infrared-light spectrum in it. This observation of transiting planet is out of question from ground since Earth has a large amount of water in it which disturbs their examination.
