The Other Planets • 2021 • episode "S1E7" Zenith: Advances in Space Exploration

Category: Technology

For most of human history, our neighboring planets were little more than dots of light in the sky with comets and asteroids being a complete mystery. Today the smaller rocky planets and asteroids are seen as the key to understanding the formation of our planetary system.

The Sun

The Sun is our star. Its energy enables life on the Earth to thrive yet we know so little about the solar weather and the 11-year solar cycle. Modern technology can be adversely affected by giant coronal mass ejections and there appears to be a link between sunspot activity and climatic conditions.
