Science@ESA Vodcast (Episode 2): Planck - Looking Back To The Dawn Of Time (Part 1): Big Bang Cosmology. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- In the Science@ESA series Rebecca Barnes will take you on a journey of discovery into the rapidly evolving field of space astronomy and planetary exploration. In this second episode Rebecca takes a close look at Planck - a European Space Agency mission built to detect radiation from the microwave portion of the electromagnetic spectrum. This mission will help find answers to some of the most important questions in modern science. • http://astronomy2009.esa.int • http://www.youtube.com/esa --- The Big Bang is the cosmological model of the initial conditions and subsequent development of the Universe that is supported by the most comprehensive and accurate explanations from current scientific evidence and observation. As used by cosmologists, the term Big Bang generally refers to the idea that the Universe has expanded from a primordial hot and dense initial condition at some finite time in the past (currently estimated to have been approximately 13.7 billion years ago), and continues to expand to this day. • http://en.wikipedia.org/wiki/Big_Bang --- Planck was selected as the third Medium-Sized Mission (M3) of ESA's Horizon 2000 Scientific Programme, and is today part of its Cosmic Vision Programme. It is designed to image the anisotropies of the Cosmic Background Radiation Field over the whole sky, with unprecedented sensitivity and angular resolution. Planck will provide a major source of information relevant to several cosmological and astrophysical issues, such as testing theories of the early universe and the origin of cosmic structure. Planck was launched on 14 May 2009 together with the Herschel satellite. After launch, Planck and Herschel separated and are now proceeding to different orbits around the second Lagrangian point of the Earth-Sun System. • http://www.esa.int/SPECIALS/Planck/index.html .
