Wonders of the Universe – Discoveries of 2011, and a look ahead to 2012


There were many discoveries during 2011 like the Earth’s own Trojan asteroid, water flowing on Mars, Pluto’s 4th moon, a star cooler than you, free-floating planets, a new type of supernova, the most distant galaxy, and the most distant quasar.  There were many cases where our understanding was improved, such as a better explanation for the Moon’s asymmetry, the origin of the rings of Saturn, a better picture of the Milky Way’s spiral arms and the origin of the first stars.  There was also the unexpected, a storm on Saturn, two nearby supernovae, and exoplanets with the densities of cannon balls and diamonds.  We will take a look back at the major astronomical discoveries and events of 2011 and some of the major celestial happenings coming up in 2012!
