Students are wondering about characteristics of the galaxies, for example what is the shape of each galaxy and milky way; how many galaxies exist in our universe and other relevant questions. Students in generalhave not realized the distances between galaxies, or the distances between stars. Performing this scenario, students observe images from JamesWebb telescope, are using the AAS worldwide telescope and the stellarium where easily can zoom in the sky and explore celestialobjects such are galaxies etc. They find the distance of galaxies from Earth; they categorize different shape of galaxies. Additionally, students identify the shape of different galaxies by participating in the citizen science project, the galaxy zoo. Students are working in small groups of four. The didactic scenario is performed using tablets or in the class of computers of the school.
