The academic year is moving on. And many secondary schools based in the region of Castilla-la-Mancha are currently immersed observing the region of Serpens through the exercise Setting references when everything moves: stellar streams. Teachers and students, all toghether, will try to find stars in the region of Serpens that have sufered motions. ¿How will they do that? By setting systems of references in the space.

This execise will allow students to understand what exactly is a system of references and why are they necessary to comprehend the motion of elements through the space.

In order to share questions and doubts, teachers participating in Discover the COSMOS' project gathered -during two sessions- with AstroHita Foundation, members themselves of Hands-On Universe.
