The second wave of 2-day tickets WED–THU and FRI–SAT has rolled over and here we have the 3rd wave 🌊

Ondřej Heigl 

He has been fascinated by space since childhood. When, as a young boy, he started carrying a football and a marble to demonstrate the difference in size between the Sun and the Earth, it was already clear that his path would lead to science communication.

Today, he can be found at the Prague Planetarium, where he helps visitors understand what is happening in the sky above them, and in schools, where he inspires the next generation to become excited about science.
