PBS Space Time Season 2019 Episode 17 The Alchemy of Neutron Star Collisions

The PBS Space Time season 2019 episode 17 titled "The Alchemy of Neutron Star Collisions" explores the fascinating and explosive phenomenon of neutron star collisions. The episode delves into the science behind these cosmic crashes and how they can create some of the universe's most spectacular and rare elements.

The episode begins by setting the scene and explaining what neutron stars are. These incredibly dense objects are created when a star dies and its core collapses, leaving behind a small but incredibly dense ball of neutrons. Neutron stars are incredibly hot and dense, and they emit a variety of types of radiation. Scientists have been studying neutron stars for decades, but it was only recently that they were able to detect the collision of these objects.

The episode then goes on to explain how these collisions occur and what happens during the collision. When two neutron stars are in close proximity, their orbit slowly deteriorates, and eventually, the two objects collide. This collision produces an incredible and explosive burst of energy in the form of gamma rays. These gamma ray bursts can be detected from Earth and can be studied to learn more about what happens during the collision.

The episode also explores how these collisions can create some of the rarest and most valuable elements in the universe. When neutron stars collide, the energy released is so intense that it can actually create new elements that cannot be produced any other way. These elements include gold, platinum, and uranium, which are incredibly valuable and important to modern technology.

Throughout the episode, the host discusses the various methods used by scientists to study neutron star collisions. These methods include observing the gamma ray bursts, studying the gravitational waves produced by the collision, and analyzing the chemical makeup of debris left behind by the collision.

Overall, "The Alchemy of Neutron Star Collisions" is a fascinating and informative episode that explores one of the most explosive and exciting phenomena in the universe. The episode offers a clear and accessible introduction to the subject matter, making it suitable for viewers with a wide range of backgrounds and knowledge. Viewers will come away with a newfound appreciation for these incredible events and the scientific discoveries they have enabled.
