The Sounds of the Universe
In space no-one can hear you scream... but it is still a noisy Universe. We are familiar with the many stunning images of space, but these are only part of the whole human experience. This lecture takes a new approach to appreciating the Universe, through the vehicle of sound. Once we understand how sound is propagated, we can look at the how and where it can exist in space. We examine how sound can be a diagnostic of cosmic phenomena (such as the song of the Sun and distant stars), the way it can carry energy across vast volumes of space (away from a black hole humming in B♭),
how it can be a useful way to illustrate processes in astronomy (such as the rapid spin of pulsars, and other more local radio emissions) and how it is ultimately responsible for the growth of all structure we see today in the cosmos.

|The Sounds of the Universe|
|Cosmos: A Personal Voyage
It covered a wide range of scientific subjects including the origin of life and a perspective of our place in the universe.
|Sound Waves: The Symphony of Physics
This is a two-part BBC documentary series hosted by Dr. Helen Czerski, which takes us on a journey into the world of sound waves and reveals what the physics of sound can tell us about the world and how it works.
|Black Hole Blues and Other Songs from Outer Space
More than a billion years ago, two black holes collided. In the final second of their long life together, the black holes banged out a rhythm like mallets on a drum, creating gravitational waves - ripples in the shape of spacetime.
|The Multiwavelength Universe
To get a complete picture of how the Universe works, astronomers must study objects over the full range of light, the electromagnetic spectrum.
|Frontiers and Controversies in Astrophysics
This course focuses on three particularly interesting areas of astronomy that are advancing very rapidly: Extra-Solar Planets, Black Holes, and Dark Energy.
|Survey of Astronomy
We'll explore the Sun, the planets, the many other objects found in the Solar System, stars and galaxies, dark matter, dark energy, the fate of the universe, and the possibility of extraterrestrial life.
During this course, you'll have the opportunity to study the cosmos from the modern perspective - what we know and what we're not sure about.
