This lecture starts the study of the Universe as a whole—or cosmology. A key finding made by Edwin Hubble in 1929 was that the spectra of distant galaxies are redshifted more than those of nearby galaxies, suggesting that the Universe is expanding.

Stephanie, Ian and Alfredo are landless ecological farmers striving to produce healthy food for local consumption in Puerto Rico. In this economically depressed US-territory -highly dependent on food imports and a frequent target for hurricanes– producing food locally is urgent. The documentary shows the protagonists’ grit as they attempt to carve a living without land ownership or capital.

In 96 richly illustrated half-hour lectures you will survey the main concepts, methods, and discoveries in astronomy—from the constellations drawn by the ancients, to the latest reports from planetary probes in our Solar System and the most recent images offered by telescopes probing the farthest frontiers of space and time.

Explores the life and times of cultural anthropologist Esther Newton. The film tells her story of awakening to gay life in the 1950’s, the women’s liberation movement and lesbian-feminism, drag culture, and forging a butch identity that for her is in conversation with trans-masculinity. Keenly attuned to the societal forces that shaped her life, Esther guides us through an anthropology of herself, a study influenced by her love for a sport –...

The unexpected finding that the Universe is expanding at an ever-faster rate lends support for the existence of a non-zero cosmological constant, a formerly discredited idea of Einstein's, which he once called his "biggest blunder."

The surface temperature of a star determines its apparent color. The hottest stars are bluish in color, and the coldest stars are reddish; stars at intermediate temperatures appear white. The Sun is a white star.

The course ends on a philosophical note, with reflections on intelligent life in the cosmos and of our place in its grand structure. Perhaps the most astonishing thing about the Universe is that we are able to contemplate and understand it through systematic studies.

Many objects in the night sky can be enjoyed with the naked eye, even from the city. These include several famous constellations, bright stars, planets, and satellites such as the International Space Station.

As Earth rotates on its axis and orbits the Sun, the night sky changes over a 24-hour period, as well as throughout the year. This lecture explains how to locate celestial bodies and why the sky appears different from place to place.
