In this video excerpt from NOVA, learn how the Hubble Space Telescope is being used to find dense disks of dust and gas particles forming around new stars like our Sun. These gas and dust particles may one day collide and clump together to form new planets and moons in a process similar to how the planets in our solar system could have formed. In activity seven from the Education Collection that accompanies this video, students observe four demonstrations of different techniques used in the search for life.
