Swiss astronomers calculated with greater accuracy than ever tithermokrasia of an exoplanet's atmosphere and found that reaches 3,000 degrees Celsius, enough to even melt iron.

Meanwhile, inside the atmosphere most powerful winds blowing at a speed of more than 1000 kilometers per hour, while on earth not exceeding 400 km / h.

The scientists of the universities of Geneva and Bern, about relevant publications in astronomy and astrophysics journals \ "Astronomy & Astrophysics \" and \ "Astrophysical Research Letters \", used the bodies of a telescope (HARPS) of the European Southern Observatory in Chile to make their measurements for exoplanet HD189733b, a relatively nearby giant gas within 63 light years from Earth.

The precision measurement opens the way for more study the atmospheres of other exoplanets. The new technique is based on spectral analysis of the chemical element sodium in the atmosphere. Where there is atmosphere, sodium emits a distinct chemical "signature" of the changes over time which is possible with the help of computers, to draw valuable conclusions on the atmosphere of a planet, density, pressure, temperature.
