As the crew of The Tardigrade prepare to land on Venus, Matthew heads back down to Earth to get some supplies.

Whilst back on the home planet, he pays a visit to St. Andrews Observatory to have a look at the James Gregory Telescope – the biggest telescope in Scotland.

The custodian of this fine piece of equipment is Dr. Aleks Scholz, an observational astronomer who studies problems in star and planet formation.

This was a good opportunity for us all to learn something new, so Aleks is going to talk us through the life cycle of a star.

Things to Learn

  • How do stars from?
  • Why does size matter when it comes to star formation?
  • How do stars die?
  • What determines the ultimate fate of a star?
  • What causes stars to explode?
  • How will our own sun die?
  • What impact will the sun dying have on the planets in our solar system?
  • If Aleks could visit anywhere in the universe, where would he go?
