Episode 4 of Experiencing Hubble
Explore the most iconic Hubble photo of all: the glowing pillars of gas and dust at the core of the Eagle Nebula. Resembling a fantasy landscape, this view shows young stars emerging from their cocoons of gas and dust in an interstellar molecular cloud.
Living with a Dwarf Star
The most common stars are class M dwarf stars, which are smaller and less luminous than the Sun (class G). Earth-sized planets are much easier to detect around M-dwarf stars, especially if the planets are within the relatively close-in habitable zone. Explore examples and the prospect for life on such…
Living with a Giant Star
In billions of years, the Sun will expand into a red giant, possibly engulfing Earth. Learn how planet-finding techniques give astronomers insight into the processes inside giant stars. Then study the planets around these behemoths for clues about Earth's ultimate fate.
The Star of Bethlehem
For centuries, astronomers have struggled to find an explanation for the Star of Bethlehem, recounted in the Gospel of Matthew. Professor Schaefer focuses on a recent theory that has taken scientists and biblical scholars by surprise, due to its success at solving problems that plagued all previous proposals.
Stars in Their Courses—Orbital Mechanics
Newton was the first to realize that objects could, in theory, be sent into orbit around Earth. Explore how this works in practice, using the ideas of energy and angular momentum to study how satellites, moons, planets, and stars move through space.
The Constellations and Their Stars
Episode 1 of Our Night Sky
Begin your study of the night sky by investigating the origin of the constellations: the traditional groupings of stars that mostly date to antiquity. The well-known constellation Orion illustrates the fascinating mix of beauty, mythology, and scientific knowledge to be found wherever you look in the heavens.
Planets Circling Two Stars
See how data from the Kepler spacecraft confirms a scenario straight out of the movie Star Wars: a planet with two suns. Investigate the tricky orbital mechanics of these systems. A double star also complicates the heating and cooling cycle on a planet. However, the view is spectacular!
Star Catalogs from around the World
The genius of Greek astronomy is epitomized by the star catalogs of Hipparchus and Ptolemy. Professor Schaefer recounts his exciting discovery of a star chart apparently influenced by Hipparchus's lost catalog. Close by comparing Greek star catalogs with those of China and the Arab world.
