World of Stars

Every day at the NHM Vienna the digital fulldome planetarium invites visitors to the museum to embark on a spectacular journey through space.

This photo shows "Io", one of Jupiter’s moons and home to the most intense volcanic activity in the solar system. Its mighty volcanoes spit material up to 300km into the air, while ash expelled by volcanoes here on Earth is only projected around 50km into the atmosphere. It is thought that two main factors are responsible for heating up Io and causing such intense geological activity: the hugely powerful gravitational and tidal powers exerted by Jupiter as well as Io’s close orbit to the planet.

Live show "Journey Through the Night", Wednesday 17:00, Sunday 14:00 and 16:00.
