In recent years, finding planets orbiting distant stars has been happening with increasing regularity. This week, the journal Science has reports of two new exosolar planet finds, including a multi-planet system. One group of astronomers used the Keck and Gemini telescopes to directly image three planets around the star HR 8799, 128 light years from Earth. In another study, a second team used the Hubble Space Telescope to image a planet they call Fomalhaut b, orbiting its star, within a large dust belt.
In this segment, we'll hear about the new work in the field of discovering exosolar planets -- including research that used the Hubble Space Telescope to take optical images of a planet orbiting a star some 25 light years away.
