Scientists Determine Temperature And Wind Speed Of A Hot, Stormy Exoplanet
No matter we can visit other worlds or not, no matter we can capture them or not, scientists will figure out the nature of atmosphere over there. We are saying this because we have encountered such an incredible observation of scientists.
Just by taking measurements of sodium emission from the exoplanet HD 189733b, the world which is estimated to be 63 light-years away from our planet, they have determined that its temperature is 3,000°C (5,400°F) with winds blowing at 500-mph.
The research team was comprised of astronomers from Universities of Geneva and Bern in Switzerland. Before reaching the theoretical models of their calculations, astronomers employed spectrometer to study spectrographic lines of sodium. The observations were carried with relatively a smaller telescope. Still the findings are capable enough to pave the way for similar measurements of other awfully distant worlds with respect to earth.
According to the findings, the temperature level at the atmosphere of the gas giant planet HD189733b is directly proportional to the altitude. At the upper most levels, the temperature rises so much so that it would melt iron. Which throws habitability beyond the bounds of possibility.
Telescopic observations returned results in accordance with theoretical study done by sub-project leader Dr Kevin Heng.
“Previous formulae assumed the atmosphere to have only a single temperature, but we know that this is probably too simplistic even for faraway exoplanets for which we have limited information,” said Heng.
HD189733b is a huge planet with mass larger than that of Jupiter. It is present in the night sky, called ‘little fox.’
