8 key ideas, each explained in our own words.

Wonders of the Universe

  1. IDEA 1

    Light carries messages from the past

    Cox explains that light from distant stars takes time to reach us. Looking into space means looking back in time, revealing the universe's history. Light is our main source of cosmic knowledge.

  2. IDEA 2

    We are made of stardust

    Cox explains that the elements in our bodies were made inside stars. When stars explode, they scatter these elements, which later form planets and people. Our origins are written in the stars.

  3. IDEA 3

    Stars live and die

    Cox describes how stars are born, burn their fuel and eventually die. Their life cycles create and spread the elements needed for life. Some explode dramatically as supernovae. Their remains seed new stars.
