A new Master’s degree programme in Space Systems will be launched at ETH Zurich in autumn 2024. Interested parties can start applying in April.
Brumadinho dam collapse: The danger emerged after the decommissioning
Research
ETH Zurich
In 2019, the tailings dam at a Brazilian iron ore mine failed. The mudslide caused a catastrophe for people and the environment. A team of researchers at ETH Zurich has now uncovered the physical mechanism that may have triggered the accident.
Permafrost: a ticking time bomb beneath our feet
Research
EPFL
Nearly a quarter of the Earth’s land surface is permanently frozen. These areas, known as permafrost, are found in northern polar regions and at high altitudes. But the permafrost is now starting to thaw – with potentially disastrous consequences for the climate. Here, we look at what scientists currently know about this potential threat.
Measuring earthquakes and tsunamis with fibre-optic networks
Research
ETH Zurich
Geophysicists at ETH Zurich have shown that every single wave of a magnitude 3.9 earthquake registers in the noise suppression system of fibre-optic networks. This method can be used to set up close-meshed earthquake and tsunami early warning systems at low cost.
Mystery of the Martian core solved
Research
ETH Zurich
Mars’s liquid iron core is smaller and denser than previously thought. Not only is it smaller, but it is also surrounded by a layer of molten rock. This is what ETH Zurich researchers conclude on the basis of seismic data from the InSight lander.
The strength of nature's weakest force
Research
ETH Zurich
Gravity keeps our feet firmly on the ground and Earth in its orbit around the Sun. Meanwhile, satellites in space measure the acceleration caused by the Earth’s gravitational pull.
