In this popular video series, real astronomers answer common questions about astronomy. Brought to you by the "Cool Cosmos" team (the joint Education and Public Outreach group for the Spitzer Space Telescope and the Infrared Processing and Analysis Center) located at the California Institute of Technology in Pasadena, California. Narrated by Dr. Robert Hurt of NASA's Spitzer Science Center. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- How do stars form? A study of star forming region W5 by the sun-orbiting Spitzer Space Telescope provides clear clues by recording that massive stars near the center of empty cavities are older than stars near the edges. A likely reason for this is that the older stars in the center are actually triggering the formation of the younger edge stars. The triggered star formation occurs when hot outflowing gas compresses cooler gas into knots dense enough to gravitationally contract into stars. Spectacular pillars, left slowly evaporating from the hot outflowing gas, provide further visual clues. In the above scientifically-colored infrared image, red indicates heated dust, while white and green indicate particularly dense gas clouds. W5 is also known as IC 1848, and together with IC 1805 form a complex region of star formation popularly dubbed the Heart and Soul Nebulas. W5 lies about 6,500 light years away toward the constellation of Cassiopeia. • http://apod.nasa.gov/apod/ap080916.html --- Cool Cosmos at the Infrared Processing and Analysis Center & the SIRTF Science Center In answering the wide public interest in space sciences, NASA has, for more than a decade, made Education and Public Outreach (EPO) an important element in their missions. This Cool Cosmos portal is the main gateway of the Cool Cosmos EPO group at the Infrared Processing and Analysis Center and the SIRTF Science Center. The Cool Cosmos EPO activities are coordinated and managed by the SIRTF Science Center, based at the Infrared Processing and Analysis Center on the campus of the California Institute of Technology in Pasadena. Communicating the world of infrared astronomy to the public is the main topic of the Cool Cosmos portal but certainly not its only goal. In the past few years the Cool Cosmos team has created a wide variety of educational products that explain the infrared as well as the multi-wavelength universe. We've produced a suite of award-winning websites (coolcosmos.ipac.caltech.edu) that speak to audiences as varied as kindergarteners to amateur astronomers. We've also filmed short videos about astronomy and infrared light and created posters and brochures that have become favorites with NASA education specialists as well as classroom teachers. The Cool Cosmos portal is involving students in science with multi-disciplinary educational materials produced with the goal of engaging the young minds of future generations of scientists. The continuous positive response of the public has been an absolute motivation to create new and innovative methods to reach them. The Cool Cosmos team is a dynamic group that has made its vocation to revive the interest, excite the dreams and hopefully answer some of the questions to satiate the public thirst for knowledge of Space. • http://coolcosmos.ipac.caltech.edu/ .
