Storm in space

A solar storm raced towards Earth on Saturday at a speed of 800 kilometres per second. So far, there has been no significant damage to the technology in space.

Doom and gloom in Stuttgart

A total solar eclipse is not something you experience every day. The people of Stuttgart were all the more disappointed when a thick cloud cover blocked their view of the black sun.

Unbelievable: amateur chemist decomposes water!

It is a sensation for science: water can be split into two parts. The French banker and amateur chemist Antoine Laurent de Lavoisier (born 26 August 1743) proved this in an amazing experiment.

The rising Earth

Topsy-turvy world – the Earth rises above the lunar horizon. On Christmas Eve 1968, the American astronaut William Anders took this famous photo.

Dance on the volcano

It is the most active volcano on earth: Kilauea in Hawaii. Since 1983, it has been spewing lava from craters and fissures, creating a magnificent natural spectacle. Kilauea measures 1247 metres, and its older siblings Mauna Loa and Mauna Kea even tower more than 4000 metres above the sea. It is about 200,000 years since
