Field(s) of activity for the internship

CESAR (Cooperation through Education in Science and Astronomy Research) is a joint educational programme developed by the European Space Agency (ESA), the Spanish National Institute for Aerospace Technology (INTA) and the public company ISDEFE. It is based at ESA’s European Space Astronomy Centre (ESAC) in Villanueva de la Cañada, Madrid, Spain. Its main goal is to provide students and teachers from European schools with hands-on educational materials and resources about Astrophysics and Space Sciences, to be carried out in the classroom, as well as easy access to ESA´s data archive and to optical and radio telescopes.

You can choose among the following topics:

1) Topic 1: Support in the pedagogical development of CESAR’s educational activities, with a special focus on the educational campaign for the upcoming solar eclipses.

The CESAR team carries out continuous work on transforming its activities and educational materials, adapting them to new formats and pedagogical strategies that are more engaging for students. Some examples include the development of new activities such as online labs, VR applications, and e-learning platforms. In this context, we follow the principles and guidelines already established by our colleagues at ESA Education, with whom the CESAR team is in regular contact. These updates are also carried out with the aim of making the materials progressively more accessible, inclusive, and diverse. In addition to continuing our usual educational activities, in 2026 the CESAR project launched a specific educational campaign in preparation for the total and annular solar eclipses that were going to be visible from Europe over the next three years. After a successful first phase related to the total solar eclipse of August 2026, we are now continuing the development of this campaign in preparation for the total solar eclipse of August 2027 and the annular solar eclipse of January 2028.

The goal of this internship would be:

- to collaborate in the development and revision of CESAR’s educational resources, with a particular focus on inclusion; - to take part specifically in the design and implementation of CESAR’s educational campaign related to the solar eclipses visible from Europe in 2027 and 2028; - to design and develop new multimedia material for the educational activities of the CESAR project, as well as its publication and impact monitoring on the project’s website and social media channels.

2) Topic 2: Support for the operation and educational implementation of CESAR’s telescopes

The CESAR Project comprises three observatories: a solar observatory with three telescopes, currently operational; a 0.5 m optical telescope at the Cebreros Observatory, fully refurbished and operational since summer 2026; and two smaller optical telescopes. These telescopes serve as resources for the CESAR project's educational activities.

The main objectives of this internship are:

- support for the educational implementation of the 0.5 m optical telescope at the Cebreros Observatory, by creating observational cases and developing the system that will allow educational institutions to request and carry out their own observations; - support for the operation of the solar and Cebreros telescopes, as well as the development of software to manage the acquired data. This includes the support in the design of a CESAR data archive, with data curation and search tools.
