ANSWER: Blue
 
Scientists have found that 100 light years away from earth, a small exoplanet with blue skies has been orbiting a red dwarf star. US astronomers used the Las Cumbres Observatory Global Telescope Network (LCOGT), a set of small telescopes spread over Texas, Hawaii, California in the US and in Chile and South Africa to make this discovery. Scientists observed the Rayleigh Scattering or detection of light scattered by tiny particles indicating a blue sky in the exoplanet. A red dwarf star is a low mass star common in the Milky Way galaxy.
