ASTR 160 - Update 3 - The “Dark Ages” and the Growth of Structure
In this third of three update lectures, Prof. Bailyn provides new information pertaining to the third part of the course, on cosmology. The basic model of the Universe, including Dark Matter and Dark Energy, is supported by all recent evidence. Work is thus beginning on sorting out the consequences of this model, in particular the growth of structure in the Universe, from tiny modulations of the Cosmic Microwave Background to the current distribution of galaxies.
ASTR 160 - Update 2 - Do Black Holes Spin?
In this second of three update lectures, Prof. Bailyn discusses new information pertaining to the second part of the course, on black holes. In this lecture Prof. Bailyn describes recent work by he and his colleagues on determining the spin of black holes, which is the only parameter of consequence other than the mass. The results of these investigations are currently ambiguous and controversial.
ASTR 160 - Update 1 - The Kepler Mission
In this first of three update lectures, Prof. Bailyn discusses new information relevant to the first part of the course, on exoplanets. In particular, Prof. Bailyn reviews the spectacular results from the Kepler mission, launched in 2009, which has discovered thousands of new exoplanets. Examples of these results are discussed, but the long-term goal of discovering Earth-like planets on which life as we know it could thrive has still not quite been achieved.

GG 140 - Lab - Quinnipiac River Field Trip
The laboratory for GG 140 consists of five exercises during the semester where the students learn to observe the atmosphere and measure important physical quantities. For Open Yale Courses we present only one of these labs; the Quinnipiac River Field Trip. This field trip introduces the students to the part of the hydrologic cycle where precipitation over the continent returns to the oceans in rivers. During a two-hour tour, we visited five sites along the Quinnipiac River observing temperature, salinity and streamflow.
