The Antarctic ice hides deep secrets

Antarctica has been pocked and razed by huge meteorites and earth forces. Under the ice, organisms have developed in isolation for millions of years.

Researchers have stolen the South Pole's ancient secrets.

Deviations in the gravitational field indicate one of the world's largest meteorite craters. At 480 kilometers, it is 2.5 times the size of the crater, causing the dinosaurs to die out. He is certainly 100 million years old.

In 2017, the researchers found evidence for a mantle diaper under West Antarctica: a huge bubble of hot rock mass from the interior of the earth. In Hawaii, diapers lead to a large volcanic activity

More is full of unique life

At least 400 lakes are hidden under ice, and with 5,400 cubic kilometers of water, Vostok Lake is the largest. According to researchers, the ecosystem has been isolated from the environment for around 25 million years.

Ice protects ancient mountains

The Gamboertsev Mountains in East Antarctica are as high as the Alps, but possibly hundreds of millions of years older. While the Alps erode through the weather, Gamboertsev is protected by approximately 3 kilometers of ice.

A huge gap divides the continent

In 2015, satellite data revealed the probably longest gap in the world. At 1100 kilometers, it is three times as long as the Grand Canyon in the US, and in some places it is more than a kilometer deep

5 reasons why Proxima b is the colony par excellence

1. The planet looks like the earth © M. Kornmesser / ESO Proxima b is a rocky planet, just like the earth, but it is about 30% heavier and maybe a little bigger. Astronomers estimate that the planet has a radius that is 80-150% the size of the Earth. 2. Short travel time Proxima b revolves around the Proxima Centauri star, which is only 4.2 light-years away from the Earth.

Mysterious planetary system does not adhere to the rules

500 Light years away from us is a planetary system that is at odds with the existing theories about the origin of planets around a young star. The CI Tau star is only 2 million years old, but has already collected four large gas planets. Astronomers from the University of Cambridge in Great Britain viewed the planetary system with the ALMA telescope.

5 deadly exoplanets

Like the earth, they revolve around a star, but the similarities kind of stop there. Astronomers are finding more and more planets that revolve around stars other than the sun, so-called exoplanets. Some resemble the earth, but the vast majority are totally unsuitable for humans. Below we provide an overview of five of the worst places to be human.
