Solar system: gravity has the power

The solar system Our solar system consists of the sun, the eight planets that revolve around it and thousands of moons, dwarf planets, asteroids and comets. The solar system was created 4.6 billion years ago. At that time the sun was born as a star in the universe, and a disk of gas and dust revolved around the young sun.

How fast can clouds drift away?

The fastest clouds are at an altitude of 10 to 18 kilometers, where the wind speed is sometimes as much as 400 kilometers per hour. That they are in that layer is because the clouds consist of water droplets or ice crystals that fall very slowly. And that means that the clouds follow the movement in the sky.

Five planets with several moons

We humans watch the moon a lot and often, we think of the moon and even write songs and poems about it. And then we only have one. There are other planets in our solar system that are more widely allocated in terms of the number of moons - and where the night sky must look fantastic.

Filthy waste is worth money

Rot fruit becomes bioplastic In this process special enzymes are used, which cut up the plant fibers in the waste. They convert the fibers into simple sugar molecules. Subsequently, bacteria break down the sugars into lactic acid, from which valuable bioplastic is made. Plastic waste becomes clothing Plastic can be ingeniously transformed into plastic polyester.

Two new planets may contain life

Last year, NASA discovered no fewer than seven earth-like planets around the Trappist-1 star. Several of them are in the habitable zone - the right distance to their star to hold life. And now an international research team has shown that six of the seven planets can contain large amounts of water.

Do expired medicines still work?

The health authorities require that drug manufacturers provide their medicines with a best-before date, so that patients can be sure that a medicine is still working and that no toxins have been formed. Producers check the shelf life by storing a medicine in the recommended way and regularly testing its effectiveness.

Antarctic volcanoes can flood Europe

A hidden volcano world can melt more than 2 million cubic kilometers of ice in West Antarctica. Until 2017, only 47 volcanoes were known in that part of the South Pole, but thanks to a groundbreaking discovery, that number has now been increased to 138. So the ice-cold continent is one of the largest volcanic areas on earth - which worries researchers.

Super eruptions are more common than previously thought

Volcanoes are a major geological threat and can cause enormous destruction worldwide. With a so-called super-eruption, 1000 gigatons of volcanic material is thrown into the air and entire continents can be covered with a layer of ash. Material will also end up in the atmosphere, as a result of which the global climate can be upset for decades.

Earth's shadow takes a bite out of the moon

About the lunar eclipse The earth casts a long shadow into the space, through which the moon occasionally passes. Sometimes the moon is completely covered by the darkest part of the Earth's shadow and we get a total lunar eclipse. Other times, that shadow falls only partially on the moon and so we also see a partial lunar eclipse - as now.
