Lost Alien Puppet Show
Jacob Berkowitz and "Ambrosia the Alien" performing the Lost Alien Puppet Show.Jacob Berkowitz is astronomy Professor Kepler in this 30-minute, interactive, theatrical-style puppet show that will take you out-of-this-world. Ambrosia the alien is lost, and needs your help to find her way home. How hard can this be? There are only eight planets in our Solar System. But, Ambrosia isn’t from our Solar System. She’s from an exoplanet—an amazing planet around another star. Join the search for an alien Earth and help this ET go home!
With fun and laughter, the show introduces audiences to the present-day search for exoplanets, and particularly another living, Earth-like planet. The show is based...

More Distant Planets Discovered
Imagine discovering eight new worlds outside our solar system while the rest of the world is on summer vacation. See what’s out of this world, thanks to the University of Texas at Austin’s McDonald Observatory and the European Southern Observatory.
