Deep in the sea it is so dark that you don't see a thing in front of you, and the salt water inhibits radio waves from radar, for example, after a few meters. Sound waves move faster under water than through the air, and therefore sonar with its distinctive ping sounds has long been a favorite to navigate underwater and track down enemy vessels.
In a new test at the international space station ISS, scientists want to cool atoms to a record low temperature of less than 0.1 trillion degrees above absolute zero. Dark energy The particles are transformed into waves, with which science can go in all directions: from following the melting of the ice caps to extremely precise weight measurements to discovering the mechanism behind the mysterious dark energy that accelerates the expansion of the universe.

At the top of Saturn, there is a hexagonal cloud pattern around the North Pole with a hurricane in the center. The hexagon is striking in itself because of its clear hexagonal shape and its diameter of up to 32,000 kilometers. And now it appears that the hexagonal cloud cover has even more surprises in store and behaves like a chameleon: it has faded in color.
