# Night observation with telescopes at Galáctica What to do en Sierra de Javalambre · Sierra de Javalambre Fuente: https://www.geocalia.com/en/spain/aragon/javalambre-mountains/things-to-do/galactica-night-sky-observation · Revisado: 2026-11-13 - Desde: 25 € per adult - Duración: 1 h 30 - Temporada: All year, on fixed nights of its calendar - Para quién: All ages Astronomy · 1 h 30 at nightfall · All ages · €25, €12 up to age 10 An hour and a half in Galáctica's outdoor amphitheatre, with guides and telescopes, beneath what the house calls one of the darkest skies in Europe. Each night on the calendar has a theme, and the guide builds the session around it. Which nights In the November and December 2026 calendar there is observation every Saturday at 20:00, and also on Sunday 6 December: the Leonids on 14 November, the Moon on the 21st, Saturn and its moons on the 28th, the welcome to the winter sky on 5 and 6 December, the Geminids on the 12th, the Moon and Orion on the 19th and the great Orion Nebula on the 26th. On a meteor shower night you learn the season's constellations and, if the sky cooperates, count shooting stars; on the Saturn night you look at the rings and some of its moons through a telescope. The rest of the year the calendar changes month by month: check it on its website. Price and booking €25 per adult, €12 for children up to age 10 and free for under-4s. Book on the website, on each night's listing. Arrive 10 minutes early. If the forecast is bad, Galáctica warns 48 hours ahead and, if at 24 hours it is still the same, cancels: you choose a voucher for the amount, valid 12 months for any activity, or an alternative indoor plan with a sky simulator and a workshop. What to bring A winter coat and closed shoes, in summer too: the house itself insists that the temperature drops a lot at night. Galáctica has no café; you can bring water and something to eat, or have dinner beforehand in Manzanera or Aras de los Olmos. If you are going to use your phone, set the brightness to minimum so as not to dazzle the group.

An hour and a half, according to each night's listing. ### Is there a minimum age? It doesn't publish one: it is for all ages and under-4s don't pay. ### Is it in Spanish? Each night's listing doesn't state the language; if you need one other than Spanish, ask before booking.
