Do we have cosmic dust to thank for life on Earth?
Do we have cosmic dust to thank for life on Earth?
It might be that what set prebiotic chemistry in motion and kept it going in the early days of the Earth was dust from outer space accumulating in holes melted into ice sheets. Researchers at ETH Zurich and the University of Cambridge have used a computer model to test this scenario. Before life existed on Earth, there had to be chemistry to form organic molecules from the chemical elements nitrogen, sulphur, carbon and phosphorus.

Earth as a test object
Earth as a test object
Physicists at ETH Zurich and the University of Zurich wanted to know whether the planned LIFE space mission could really detect traces of life on other planets. Yes, it can. The researchers reached this conclusion with the help of observations of our own planet. Life is indeed possible on Earth. This has been demonstrated in a study conducted by the Institute of Particle Physics and Astrophysics at ETH Zurich.

Impact of the DART space probe could have deformed an asteroid
Thanks to simulations with a software system developed at the University of Bern, an international team under Bernese leadership has provided important insights into the impact of NASA's DART space probe on the asteroid Dimorphos: it is very likely that not just a crater was created, but the entire asteroid was reshaped.

Water-worlds, the key to an exoplanet enigma
Water-worlds, the key to an exoplanet enigma
Exoplanets with a radius twice that of the Earth are rare. A team from MPIA, UNIGE and UNIBE has come up with new explanations. Why are so few exoplanets about twice the size of Earth detected? On the basis of computer simulations, a team from the Max Planck Institute for Astronomy (MPIA) and the Universities of Geneva (UNIGE) and Bern (UNIBE) has confirmed that the migration of sub-Neptunes planets - water-worlds - could explain this absence.

Moon rocks with unique dust found
Moon rocks with unique dust found
A research team from the University of Münster has discovered for the first time meter-sized rocks on the surface of the moon that are covered in dust and presumably have unique properties - magnetic anomalies, for example. The findings help to understand the processes that form and change the lunar crust.
