The Tucson Museum of Art displays work from refugee artists who are part of The Owl and Panther Project; space scientist Chris Impey looks "Beyond"; and Beth Surdut faces off with an angry raptor in "The Art of Paying Attention".
This artist's concept depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The habitable zone is a region around a star where temperatures are right for water -- an essential ingredient for life as we know it -- to pool on the surface. Scientists do not know if Kepler-452b can support life or not. What is known about the planet is that it is about 60 percent larger than Earth, placing it in a class of planets dubbed "super-Earths."
