Astronomers discover exoplanet clear of clouds as it is an important breakthrough in the search for the elevated comprehension of planets surpassing our Solar System. An international team of astronomers, led by Dr. Nikolay Nikolov from the University of Exeter, have discovered that the atmosphere of hot Saturn WASP-96b is clear of clouds.
Utilizing Europe’s 8.2m a massive Telescope in Chile, the group studied the atmosphere of WASP-96b when the planets cruised through front of its host-star. This permitted the team to evaluate the diminishing of starlight engendered by the planet and its atmosphere and hence decide the planet’s atmospheric composition.
As different individuals possess different fingerprints atoms and molecules have distinctive incorporeal features that can be utilized to discern their existence in celestial objects. The spectrum of WASP-96b displays whole fingerprint of sodium, which can only be seen in an atmosphere that is cloud free.
WASP-96b is a predictable 1300K hot gas giant akin to Saturn in mass and surpassing the size of Jupiter by 20%. The planet sporadically journeys a sun-like star 980 light years away in the southern constellation Phoenix, halfway between the southern jewels Fomalhaut and Achernar.
It has long been forecasted that sodium prevails in the atmosphere of hot gas-giant exoplanets, and in cloud less atmosphere it will generate spectra resemble camping tent in shape. Nikolay Nikolov, lead author and from the University of Exeter said that they have been observing more than twenty exoplanet transit spectra. WASP-96b is the only exoplanet that seems to be devoid of clouds and displays such an explicit sodium signature, producing the planet a benchmark for delineation.
