Artist's View of Extrasolar Planet HD 189733b
This illustration shows a hot-Jupiter-class planet orbiting its yellow-orange star, HD 189733. NASA's Hubble Space Telescope measured the actual visible-light color of the planet, which is deep blue. This color is not due to the presence of oceans, but is caused by the effects...
Visible-light Color of Planets Plot
This plot compares the colors of solar system planets to the color of the hot-Jupiter-class planet HD 189733b. With the exception of Mars, the colors are primarily determined by the chemistry of the planets' atmospheres. Earth's blue atmosphere plus the blue tint of the oceans...
