Yesterday our eldest handed out the invitations for her birthday party. It will be a constellation themed festivity, because we're going to visit an observatory. To be honest, I never really looked at the stars before she came up with this theme. But watching the evening sky turns out to be a fascinating thing (how could I have missed this?). A few days ago J discovered her first constellation from her bedroom window: Orion. I found the idea for the invitations here.
