Earth is not isolated in space but surrounded by an array of potentially hazardous objects within our own solar system and beyond. Although none of these provide an immediate threat to life, it is the work of scientists around the world to continue monitoring their presence, potential risk and how to minimize the risks.

Dr. Ryan French explores the science of multiple space hazards and discusses the probability and potential impacts of each of them.

Topic covered include: Asteroids & near-Earth objects, Space weather, Earth polarity flips, Space junk, stellar and black hole collisions
