All these stars are in our galaxy, several million billion kilometers from us. Photographed by the Hubble Space Telescope, they belong to the family of planetary nebulae.

Welcome to the wonderful world of plankton! Plankton are tiny living creatures that are carried in the water.

This is a satellite photo of a small part of Kansas. And those disks? Fields watered by a rotary sprinkler system. The red color highlights the wettest areas where the vegetation is densest due to the intensive irrigation, not without ecological impact.

Here is the Sun, as seen by the American Solar Dynamics Observatory satellite.

Take a look here and project yourself 2,400 years back in time: Greek columns, there you are! We are in Delphi, in front of the Tholos. In 2013, French researchers digitized the famous rotunda with this portable scanner.
