The evidence is that the universe is close to uniform; it has no observable center or edges; and that it is expanding. Cosmologist James Peebles, professor emeritus at Princeton University explores the histories of these ideas and the present state o...f the evidence for their reliability.

Nova: Science Now on PBS | "Where did we come from?" with host Neil DeGrasse Tyson explores the origin of our solar system and the start of life itself, how head lice figure in human evolution, and more. Journey back in time to the birth of our solar... system to examine whether the key to our planet's existence might have been the explosive shockwave of an ancient supernova. Meet a chemist who has yielded a new kind of "recipe" for natural processes to assemble and create the building blocks of life. And see how the head louse, a creepy critter that's been sucking our blood for millions of years, is offering clues about our evolution. Finally, meet neuroscientist André Fenton, who is looking into erasing painful memories with an injection.

This animation tracks several gamma rays through space and time, from their emission in the jet of a distant blazar to their arrival in Fermi's Large Area Telescope (LAT). During their journey, the number of randomly moving ultraviolet and optical ph...otons (blue) increases as more and more stars are born in the universe. Eventually, one of the gamma rays encounters a photon of starlight and the gamma ray transforms into an electron and a positron. The remaining gamma-ray photons arrive at Fermi, interact with tungsten plates in the LAT, and produce the electrons and positrons whose paths through the detector allows astronomers to backtrack the gamma rays to their source. (01:46) There is no narration, just a soundtrack.
