New Discoveries about Jupiter’s Great Red Spot
Our solar system’s biggest planet, Jupiter, has a giant red spot that it can be seen through earth’s telescopes. Scientists believed it to be a storm, which Voyager missions proved to be true. This storm is three times bigger than the Earth.
The darkest red part of the spot turns out to be warmer compared to the other parts of the spot. It’s 6 degrees fahrenheit warmer. The spot’s average temperature: negative 256 degrees fahrenheit.
Scientists believe that there is something in the spot’s interlinking of environmental conditions – such as temperature, winds, pressure and composition that influences the spot’s color. Initial beliefs state that what makes the area red is that sulphur molecules are being tossed up by the storm and reflects a red color through ultra-violet radiation.
The great red spot has been present ever since it was discovered in 1831 and scientists believed it formed in 1665.
In 1938, three smaller spots formed in the surface of Jupiter that is colored white. Throughout the years they grew in intensity and has changed color from white to, you guessed it, red.
