nostra nau describes the Earth, the Moon, the Sun, the planets, the stars, the constellations, the galaxies... visualised through images coming from observation and computer animations specially produced according to the astronomical and scientific models. Each video -about 5 minutes with musical background by a different author each day- invites to the discovery and the enjoyment of the Universe; the set of all videos constitutes an assorted introduction to Astronomy. 

nostra nau was daily broadcasted through the K3/33 channel of Television of Catalonia from October 2001 to June 2002 and from October 2002 to May 2003. Alongside the daily broadcasting of the TV program, a companion website offered (and continues to offer) the text and some frames of each episode, plus a guestbook and postcards. At present, the website is kept active in favour of a daily glance to the stars, and offers too a news digest, a collection of links and other resources.

On February 2004, with the collaboration of the Education Department of the Government of Catalonia, it was published a box of 3 DVD with the whole series in quality video, totaling more than 10 hours of astronomical knowledge atractively exposed for all audiences.

Since November 2004, the educational network Edu365 allows to view on line all the videos. A sample may be viewed too at YouTube.

nostra nau is a coproduction by Televisió de Catalunya, S.A. and BNC Produccions, S.L. The scientific direction is by Josep M. Oliver (Astronomical Asssociation of Sabadell) and the audiovisual direction by Xavier Berenguer (more credits in the companion website).
