The more we know about the Cosmos the stranger it seems to get. The new Kepler space telescope has detected many new “exoplanet”—planets in other star systems. Some of these planets are quite strange. One has the density of Styrofoam. Another seems to be hotter than the star it revolves around. Kinks in the Kepler telescope’s sensors have been worked around using computers and the ground and it is now providing amazing data from millions of star systems. The refurbished Hubble Space Telescope has now peered more deeply into the past than ever before to almost the dawn of the Universe. In addition, the James Webb Telescope will soon allow us to see even further back in time. Come hear Dr. Eric P. Smith, NASA astrophysicist show and tell us about the Latest and Greatest News from the Cosmos.
