Swiss scientists examined the ' Hot Jupiter ' planet HD 189733b . Temperatures reach 3,000 ° ##c in the atmosphere and orbital speed is 300 mph . Findings were comparable in size to the Hubble Space Telescope . But the researchers used a ' relatively dinky ' telescope , suggesting the telescope could be used by other astronomers to observe exoplaents .
Swiss researchers examined the 'Hot Jupiter ' planet HD 189733b . Temperatures reach 3,000°C in the atmosphere and wind speed is 620mph . Findings were comparable in quality to the Hubble Space Telescope . But the researchers used a 'relatively dinky ' telescope , suggesting the method could be replicated by other astronomers to study exoplaents .
