A team of astronomers from the University of Milan has measured for the first time the volume and distribution of water in the protoplanetary disk of a young star. The measurements were carried out with the ALMA millimeter antenna array of the Southern European Observatory. The work allowed us to look at the solar system 4,5 billion years ago and understand how and where water could have appeared on Earth in the volume in which we see it around us.
