Constellations in 3D
Eduard Masana, lecturer at the Physics Faculty and researcher of the Gaia group of the Institute of Cosmos Sciences of the University of Barcelona (ICCUB), explains how the perspective changes the way we see the stars in the sky, and how not all the stars are at the same distances, but they could be very far from each other. Using Orion as an example, this video guides us to build the constellation in 3-D.
This activity was organised by the “VI Festa de la Ciència de la Universitat de Barcelona” in virtual version with the aim to keep the connection between research and society, after the cancelation of the “Festa” face to face activities due to the COVID-19 pandemic. This is one of the activities that normally take place in groups from schools and it can now be enjoyed from home thanks to this virtual form.
