An ESPRESSO to Other Worlds

Free entrance
Nearly all the stars we see in the sky have planets around them. This motivated a Portuguese astronomy and engineering adventure in the World's driest desert. Among photographs and memories of this adventure, join us and experience this desire to find other “Earths” in the Universe.

20 years of Portugal at ESO

Participate in an online session to celebrate twenty years of the expansion of Portuguese Astronomy with ESO. From the discoveries enabled by ESO telescopes to the adventure of building astronomical instruments at the leading-edge, there is plenty to celebrate.
