Vasiona (Serbian: Васиона - Universe) is a magazine for popularization of astronomy published by the Astronomical Society Ruđer Bošković.

It is published for more than half a century and is the oldest magazine for popularization of natural sciences in Serbia.

For the Astronomical Society, Vasiona was the continuation of work on the magazine Saturn, which was published before World War II.

Cooperation with the "astronauticists" was very successful until 1962 when they have stopped financing the magazine, and so Vasiona had to reduce its format.

In the 1970s the number of astronautical articles reduced so much that since 1980 Vasiona is purely astronomical magazine.
