Earth and Mars were formed from inner Solar System material
Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit. A group of researchers led by the University of Münster report these findings today in the journal "Science Advances".

Infant stars identified at the centre of our galaxy
What was previously identified as a gas and dust cloud at the centre of our galaxy actually consists of three very young stars. That is the result of a new study led by scientists from the University of Cologne's Institute of Astrophysics. The European Southern Observatory's Very Large Telescope (VLT) - a telescope with mirror diameters of 8.20 metres on the summit of Cerro Paranal in Chile - provided the data for the study, which has appeared in The Astrophysical Journal .

The tetra-neutron - a miniature neutron star
While all atomic nuclei except hydrogen are composed of protons and neutrons, physicists have been searching for a particle consisting of two, three or four neutrons for over half a century. Experiments by a team of physicists of the Technical University of Munich (TUM) at the accelerator laboratory on the Garching research campus now indicate that a particle comprising four bound neutrons may well exist.

The uneven universe
Researchers study cosmic expansion using methods from many-body physics / Article published in -Physical Review Letters- It is almost always assumed in cosmological calculations that there is a even distribution of matter in the universe. This is because the calculations would be much too complicated if the position of every single star were to be included.

Analysis of Mars’s wind-induced vibrations sheds light on the planet’s subsurface properties
Seismic data collected in Elysium Planitia, the second largest volcanic region on Mars, suggest the presence of a shallow sedimentary layer sandwiched between lava flows beneath the planet's surface. These findings were gained in the framework of NASA's InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), in which several international research partners, including the University of Cologne, collaborate.

Black hole found hiding in star cluster outside our galaxy
International research team of astronomers including Göttingen University use "dynamical method" to discover small black hole Using the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers including the University of Göttingen have discovered a small black hole outside the Milky Way by looking at how it influences the motion of a nearby star.

Late bombardment of the Moon revealed
Planetologists from Münster investigate origin of heavy bombardment of the Moon 3.9 billion years ago / Publication in "Science Advances" The lunar surface is covered by numerous craters that date back to the impacts of asteroids. Age determinations on lunar rocks formed during these impacts show a surprising clustering at ages of about 3.9 billion years before present, or about 500 million years after the Moon was formed.

How the Sun’s magnetic forces arrange gas particles
Research team including Göttingen University observes charged particles 70 percent faster than uncharged Solar prominences hover above the visible solar disk like giant clouds, held there by a supporting framework of magnetic forces, originating from layers deep within the Sun. The magnetic lines of force are moved by ever-present gas currents - and when the supporting framework moves, so does the prominence cloud.

Bombardment of Planets in the Early Solar System
Studies of the asteroid Vesta provide new findings on the formation of Earth-like planets The largest asteroid in our Solar System - Vesta - was exposed to an extensive series of impacts by large rocky bodies much earlier than previously assumed. Researchers of an international collaboration, including earth scientists from Heidelberg University and Freie Universität Berlin, reached this conclusion based on analyses of Vesta meteorites, numerical simulations, and observations carried out with the space probe Dawn in 2011 and 2012.

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.
