Life has existed on Earth for billions of years. Stabilising mechanisms have helped our planet remain habitable to this day.

Does life exist elsewhere in the universe? There’s a good chance it does – though it might look very different to life on Earth. Scientists may soon be able to offer a definitive answer.

Nobel laureate and astrophysicist Didier Queloz and earth scientist Cara Magnabosco on the origin of life on Earth, complex life beyond our planet, and the inevitable end of every life.

Daniel Angerhausen believes that fundamental research is essential, especially in the current crisis. Still, he wonders if we shouldn’t extend the idea of sustainability into the infinite reaches of outer space.

Following two large meteorite impacts on Mars, researchers have observed, for the first time, seismic waves propagating along the surface of a planet other than Earth. The data from the marsquakes was recorded by NASA’s InSight lander and analysed at ETH Zurich in collaboration with the InSight Science Team. It provides new insights into the structure of the Martian crust.

Until now, Mars has been generally considered a geologically dead planet. An international team of researchers led by ETH Zurich now reports that seismic signals indicate vulcanism still plays an active role in shaping the Martian surface.
