Star formation is one of the most important aspects of stellar evolution. With the aid of infrared cameras we can now probe deep into regions where stars are in the process of forming. The data we obtain provide important clues to the principal problems of star formation: How does a collapsing cloud lose energy rapidly enough to enable a star to form? How does a forming star stop rotating? How does the star eliminate magnetic fields? This program reveals how observations of the youngest known stars provide solutions to these problems.

The Origin of the Universe

We leave for last the biggest problem: How did the universe itself originate? This program examines the contributions of modern particle physics to the solution of the problem; the Inflationary Model of the early universe; the asymmetry between matte...(more details)
 
Matter and the Universe

How do we see immense objects at immense distances? What are the empirical bases for theories of the Big Bang and the origin of matter? This program shows how radio telescopes and observatories provide complementary images of celestial objects, shows...(more details)
 
The Grand Design

This program takes us on a tour from our own backyard to the outer reaches of the universe. Along the way, we encounter the principal players in the universe and gain a sense of the astonishing scale of this magnificent structure. Upon our return, we...(more details)
 
The Origin of Galaxies

This program presents a possible scenario for the origin of the universe. Though much of what is believed about the universe's early history remains conjecture, advances in science technology have provided intriguing clues to the question of when the...(more details)
 
The Origin of Quasars

With the development of radio astronomy following World War II, it became apparent that galaxies contain magnetic fields and very-high-energy particles. What came as a complete surprise was the finding that some galaxies are extraordinarily powerful ...(more details)
