The Art and Science of NASA’s Best Exoplanet Illustrations #gtchat #homeschool #stem #astronomy Many new exoplanet discoveries have come from NASA’s Kepler space telescope, a space-based observatory that carefully watched the light of more than 150,000 stars to try and detect a tiny dimming of brightness (though sadly, it suffered a malfunction last year that has rendered it inoperable). This dip represents a planet passing in front of that star and eclipsing its light. Kepler can’t give astronomers much more than a few pieces of information about each exoplanet; its approximate size, the distance from its star, the length of its year, and an estimate of its surface temperature.
