A free astronomy workshop will take place in Sarrià on 28 October. Children aged 9 to 12 will explore stars and galaxies, then make a galaxy to take home.
On Wednesday 28 October, children aged 9 to 12 will meet at Biblioteca Sarrià – J. V. Foix in Barcelona for an astronomy workshop. The free session runs from 17.30 to 19.30. Each participant will make a small galaxy to take home.
The programme is called #EstàsON: ¡Dentro del universo explorando estrellas y galaxias! It will take place at Plaça de Sarrià, 1, in the Sarrià neighbourhood of the Sarrià-Sant Gervasi district. Families can treat it as a two-hour outing with both an introduction to space and practical work.
It is not a lecture-only session.
Xarxa Punt TIC describes the wider #EstàsOn programme as a series of around ten STEAM workshops running from September to December at Canòdrom. The sessions use games and experiments for children aged 6 to 12, including a workshop on stars and galaxies for the 9–12 age group.
Children will take part as young astronomers. Xarxa Punt TIC describes the wider #EstàsOn programme as a set of practical STEAM workshops. The activities combine digital learning with science and use games and experiments instead of relying only on lectures.
During the session, children will look at what stars are and how they form. They will learn how starlight travels through space. The workshop will also cover how people have used the sky to find their way for thousands of years.
Constellations and galaxies are part of the programme. Children will also explore the sky with digital tools similar to those used by scientists. The final task brings the lesson back to something they can hold.
Each child will create a galaxy in a jar. They can take it home afterward. The organisers describe the finished object as a small piece of the universe.
The European Commission Representation in Barcelona reported that Catalonia’s 2026 European Researchers’ Night brought together more than 200 activities during the week across different venues, including libraries and civic centres. The event places local workshops such as this one within a wider regional programme of public-facing science communication.
Admission is free, but advance registration is required. Families can register through Biblioteca Sarrià – J. V. Foix or by calling 930 885 220. Registration runs from 28 September 2026 until 17.00 on 28 October 2026.
Biblioteques de Barcelona is organising the event with Barcelona Activa. The activity is for children between nine and twelve, with families invited to take part. There is no separate adult programme.
Barcelona libraries and civic centres are often used for free or low-cost learning and community activities. Barcelona Urbana has described that wider use of city venues in its overviews of Barcelona libraries and civic centres.
For families in Sarrià, the offer is simple. One weekday afternoon provides an introduction to stars, constellations and galaxies without an admission fee. Places must be booked in advance, and the age range keeps the session focused.
The workshop gives children a direct way into astronomy. They hear about space, use digital tools and make something themselves. That is a different experience from sitting through a standard talk.
