A gust of solar wind speed is often a million miles per hour toward the planets. Most wind is deflected by a circular magnetic shield around the planet. Earth, for example, has a strong magnetic shield that protects the atmosphere from the strongest storm. Not so with Venus. The hottest planet in the solar system has a weak magnetic shield, which makes the solar wind often come into contact with the planet's atmosphere. As a result, Venus has an active space weather.
Recent research has shown the Journal of Geophysical Research published February 29, 2012 found evidence of the atmosphere of Venus are popped. This event is known as the hot flow anomaly.
This remarkable phenomenon occurs when the solar wind hit the atmosphere so that the U-turn. This reversal in wind direction causes the particles in the atmosphere quickly attracted to the sky. "The explosion capable of moving downwind exceed the speed of sound," said David Sibeck, researchers from the NASA's Goddard Space Flight Center.
Verification is done by combining the data distribution of charged particles and magnetic fields of data collected by the planet Venus Express spacecraft and Messenger. Both vehicles are blasts confirmed the incident on March 22, 2008. In addition, it is known that the eruption produced a plasma temperature of 10 million degrees Celsius which expands to the size of the earth.
Hot flow anomalies also occur on Earth, Mars, and Saturn. On this third planet explosion usually occurs in the top layer of the atmosphere. As for the minimal protection of Venus, an explosion occurred in a layer near the planet's atmosphere.
According to Glyn Collinson, planetary researchers from Goddard, the explosion could create the atmosphere of Venus in the daytime aurora. Meanwhile, a similar explosion in the Earth can not be seen except using radio waves.
Incidence of hot flow anomalies on the planet Venus lack a magnetic field as an indication that this phenomenon is common in all the planet. *** [PHYSORG | ANTON WILLIAM | KORAN TEMPO 3816]
