A Trace of Galaxies at the Heart of a Gigantic Galaxy Cluster
Very large yet faint galaxies have been found where no one would have expected them - in the middle of a giant galaxy cluster. Heidelberg astronomers discovered the extremely-low-density galaxies, known as ultra-diffuse galaxies, a find that is "both remarkable and puzzling", states Dr Thorsten Lisker.

Complex Gas Motion in the Centre of the Milky Way
Complex Gas Motion in the Centre of the Milky Way
How does the gas in the centre of the Milky Way behave? Researchers from Heidelberg University, in collaboration with colleagues from the University of Oxford, recently investigated the motion of gas clouds in a comprehensive computer simulation. The new model finally makes it possible to conclusively explain this complex gas motion.

Jupiter is the oldest planet of the Solar System: Cosmochemists from Münster precisely date Jupiterâ? s formation for the first time
Jupiter is not only the largest planet of the Solar System, but it is also the oldest, say researchers from the University of Münster. They, for the first time, determined a precise age of Jupiter, which was previously only approximately known. One problem has always been that there are no samples from Jupiter and, therefore, that no direct measurements were possible.

Early arrival of water on Earth: Findings of planetologists in Münster contradict hypothesis of a late cometary origin / Publication in "Nature"
Water on Earth is the precondition for life as we know it. But where does it come from, and how long has it been here? Scientists currently discuss two possibilities: Either water was here at an early stage, during the main phase of Earth's formation, or Earth was initially completely dry and water only arrived later - through the impacts of comets or 'wet' asteroids originating from the outer areas of the solar system.

Earth contains more dust from red giant stars than primitive meteorites
Earth contains more dust from red giant stars than primitive meteorites
All objects in our solar system are build from matter synthesized in previous generations of stars. Using high-precision isotope measurements of neodymium and samarium, scientists from Münster (Germany), Chicago and Livermore (USA) have now found that Earth contains more material from red giant stars than primitive meteorites (chondrites) located in the asteroid belt between Mars and Jupiter.

The death of a planet nursery?
The death of a planet nursery?
The dusty disk surrounding the star TW Hydrae exhibits circular features that may signal the formation of protoplanets. LMU astrophysicist Barbara Ercolano argues, however, that the innermost actually points to the impending dispersal of the disk. When the maps appeared at the end of March, experts were electrified.

Researchers report on findings from Dawn space mission
Researchers report on findings from Dawn space mission
In 2015 the Dawn spacecraft reached the asteroid Ceres, the largest celestial body in the so-called asteroid belt between Mars and Jupiter. The data collected by Dawn will make it possible for scientists to analyse the geological properties of Ceres and understand its origins. The latest issue of the "Science" journal contains reports by several international teams of researchers on their findings.

Lore of lonely regions
A research group led by LMU physicist Nico Hamaus is calculating the dynamics of cosmic voids and deriving new insights into our entire universe. Much of our universe is taken up by vast, hollow regions of empty space, which we call cosmic voids. They are forever expanding as the tiny amounts of matter they contain are striving to reach the outer edges, attracted by the gravity of the denser regions surrounding them.

Planetary Striptease
Planetary Striptease
Planets of the 'super-Earth? category lose their atmosphere through too great proximity to their star. That is the result of an international research project coordinated by astronomer Dr. Mia Lundkvist, who is doing post-doc research at the Königstuhl observatory of Heidelberg University's Centre for Astronomy (ZAH).

Confirmation of supernova explosion in the neighborhood of our solar system
Confirmation of supernova explosion in the neighborhood of our solar system
Approximately two million years ago a star exploded in a supernova close to our solar system: Its traces can still be found today in the form of an iron isotope found on the ocean floor. Now scientists at the Technical University of Munich (TUM), together with colleagues from the USA, have found increased concentrations of this supernova-iron in lunar samples as well.

Heidelberg Researchers Analyse Chemical Composition of Dust from Beyond the Solar System
The Cosmic Dust Analyser on the international Cassini spacecraft has detected the faint but distinct signature of dust coming from outside our Solar System, from the local interstellar cloud: an almost empty bubble of gas and dust we are travelling through with a distinct direction and speed. This graphic summarises the location of Saturn, and the Solar System, with respect to the local interstellar cloud, and our place in the Milky Way galaxy.

Dark Matter: CRESST searches for "lightweights"
The Earth, planets, stars, and galaxies form only the visible portion of the matter in the universe. Greater by far is the share accounted for by invisible "dark matter". Scientists have searched for the particles of dark matter in numerous experiments - so far, in vain. With the CRESST experiment, the search radius can be considerably expanded: The CRESST detectors are being overhauled and are then able to detect particles whose mass lies below the current measurement range.

The symmetry of the universe
The symmetry of the universe
Our existence is still a great mystery in theoretical physics. Why did anti-matter disappear almost completely from our universe, whereas matter did not? Scientists are attempting to solve this mystery at the particle accelerator of the major European research institute at CERN. The ALICE collaboration has now published the most precise measurement of the properties of light atomic nuclei and anti-nuclei ever made in the "Nature Physics" journal.
