«Dear students, I’m excited to share with you a great news.
A new astronomical observatory has been built.
It’s definetely the best in the World.
I’ve the honour and the responsibility to recruit some brilliant students to work in this wonderful site.
I would love to recruit all of you, but clearly it’s impossible.
So, in order to take this difficult choice I set up a challenge.
You’ve been split in several groups.
The goal is clear: to find an ancient telescope owned by a famous scientist from the past.
The competition is a chain of riddles and enigmas.
The winners will be in the staff of the Observatory: they’ll make great science with an impressive salary.
