Lecture 3 of Leonard Susskind’s Modern Physics concentrating on Cosmology. Recorded January 26, 2009 at Stanford University.

This Stanford Continuing Studies course is the fifth of a six-quarter sequence of classes exploring the essential theoretical foundations of modern physics. The topics covered in this course focus on classical mechanics. Leonard Susskind is the Felix Bloch Professor of Physics at Stanford University.

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.

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.

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.

An international team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a ghostly ring of dark matter formed long ago during a colossal collision between two galaxy clusters. This is the first time that dark matter has been found with a distribution that differs substantially from the distribution of ordinary matter.

COSMOS Video News Release
For the first time ever, astronomers have been creating a three—dimensional map of how the dark matter is distributed across the Universe. An international team of scientists, among them groups from Marseille, the Max-Planck Institutes and Paris have been using data from the NASA/ESA Hubble Space Telescope. The results are published in nature online of 8 January 2007, and at the meeting of the American Astronomical Society in Seattle. This Video News Release discussed this discovery.
