Today we have gone to the UdG's Parc Tecnològic to learn about Astronomy.
We've been in a Planetarium and we have looked at stars, contellations, galaxies, the planets, meteorites...It's been very good.
We've looked at the Sun spots through a telescope but today there were very small spots.
We've used computers to calculate the time the Sun needs to rotate. To do this we've observed the spots in some pictures taken day after day with a satellite.
We think it's been an interesting activity, some parts even funny, but it's been difficult to understand everything.
