Virtual experiments: Münster University geophysicists research the Earth’s origins on the computer
Although Dr. Christian Maas does his research only on the computer, it's sometimes as if he were standing in a laboratory. "I do experiments," he says. By means of his virtual experiments, geophysicist Maas is investigating a question that couldn't be answered in any lab in the world: the question of the how the Earth came into being.

Asteroid crater on Earth provides clues about Martian craters
Research team led by the University of Göttingen discovers crater floor sagging from bowl-shaped volcanic ash layer The almost 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. Its structure is comparable to the craters currently being explored on Mars. In addition to various other deposits on the rim of the basin, the crater fill is mainly formed by stratified clay deposits.

The very first structures in the Universe
Astrophysicists at the Universities of Göttingen and Auckland simulate microscopic clusters from the Big Bang The very first moments of the Universe can be reconstructed mathematically even though they cannot be observed directly. Physicists from the Universities of Göttingen and Auckland (New Zealand) have greatly improved the ability of complex computer simulations to describe this early epoch.

The same sea level for everyone
The Earth's gravity field as the basis for an International Height Reference System Maps generally indicate elevation in meters above sea level. But sea level is not the same everywhere. A group of experts headed by the Technical University of Munich (TUM), has developed an International Height Reference System (IHRS) that will unify geodetic measurements worldwide.

Cosmic web offers insights into the history of the Universe
Research team including Göttingen University observe for the first time extremely faint filaments The Universe is criss-crossed by a cosmic web consisting of large filamentary gas structures in which galaxies should form. The existence of this network confirms the most important predictions about how the structure of the Universe changes.

Ideal for Analysing Planetary Atmospheres
By analysing signals from the star Gliese 486, an international research team has discovered a hot rocky exoplanet with remains of a planetary atmosphere. Due to its characteristics, it is ideally suited for testing future observational methods of studying distant planetary atmospheres. The discovery of Gliese 486b, as the new planet has been named, was made possible by the CARMENES instrument.

Breaking the warp barrier for faster-than-light travel
Astrophysicist at Göttingen University discovers new theoretical hyper-fast soliton solutions If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein's theory of general relativity would require vast amounts of hypothetical particles and states of matter that have -exotic- physical properties such as negative energy density.

Glowing hot super-Earth nearby
Research team with Göttingen University participation plans to test atmospheric models of the rocky planet In the past two and a half decades, astronomers have discovered thousands of exoplanets made of gas, ice and rock. Only a few of them are Earth-like. Studying their atmospheres with the instruments currently available is a major challenge.

The Role of Turbulence in the Birth of Stars
Computer simulations of turbulence in interstellar gas and molecular clouds - simulations so complex they were inconceivable until now - have provided important new insights into the role turbulence plays in the formation of stars. For the first time, the results of the calculations suggest how these turbulent movements transition from the supersonic to the subsonic range.

Breakthrough in nuclear physics
High-precision measurements of the strong interaction between stable and unstable particles The positively charged protons in atomic nuclei should actually repel each other, and yet even heavy nuclei with many protons and neutrons stick together. The so-called strong interaction is responsible for this.
