Other Worlds: The Search for Extrasolar Planets
Join scientists in the search for planets outside our own solar system. Enter a cloud of interstellar dust and gas to discover the birth of a distant star and how planets are formed in its orbit. Next, step into a virtual planetarium that allows you to navigate across Earth's nighttime skies in search of known planetary systems. As you look at the night sky, think about what would be the most difficult challenges for finding new extrasolar planets. (This interactive is not Mac compatible.)
