Atmospheric Erosion On A Far Away Planet
– “For You To Enjoy And Share With Friends” –
An Exo-planet, HD 189733b, which is about 63 light years away and has repeatedly been studied by Hubble has for the first time given us a glimpse of a changing atmosphere on a planet outside our Solar System. A flare from the planets star was seen scorching the upper atmosphere of the planet and driving parts of the atmosphere off into space! Astronomers classify this planet as a ‘hot Jupiter’, it is a gas planet but only 3 million miles from its Sun which means it completes an orbit every couple of days and its atmosphere is almost 2000 degrees fahrenheit.
The researchers estimate that at least 1,000 tons of gas was leaving the planet’s atmosphere every second at speeds greater than 300,000 miles per hour. This is only the second ‘evaporating planet’ that we have come across.
