New Hubble constant measurement using cosmic lenses
New measurement of the universe's expansion rate strengthens call for new physics Using cosmic lenses an international team of astrophysicists determined the universe's expansion rate, completely independent of any previous method. The researchers' result further strengthens a troubling discrepancy between the expansion rate calculated from measurements of the local universe and the rate as predicted from background radiation of the early universe.

More accurate than expected
Despite their extremely small mass, neutrinos play a key role in cosmology and particle physics. After evaluation of the first measurement results in the Karlsruhe Tritium Neutrino Experiment (KATRIN), it is now clear: The previously unknown mass of the neutrinos must be less than 1 electron volt. This result is more accurate than previous measurements and raises hopes of discovering new neutrino properties.

New results for the mass of neutrinos
Apart from photons, the fundamental quanta of light, neutrinos are the most abundant elementary particles in the universe. As they possess a small non-zero mass, these “light-weights of the universe” play a key role in cosmology and particle physics. The most precise scale for neutrinos in the world is the international experiment "KATRIN" at the Karlsruhe Institute of Technology, in which scientists of the University of Münster are also involved.

Closing in on elusive particles
In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory is looking for signs of neutrinoless double beta decay. The experiment has the greatest sensitivity worldwide for detecting the decay in question. To further improve the chances of success, a follow-up project, LEGEND, uses an even more refined decay experiment.

"It was the greatest adventure of the 1960s"
Professor Schreiber, how big an impression did the Moon landing make on you when you were young? It wasn't just the Moon landing as such. What amazed me most were the steps that led up to it. It was a huge technical challenge. For example the question: How do I accelerate a rocket to reach the Moon? Back then, the technical possibilities were still quite limited.

Hunting for "ghost particles": Neutrino observatory at the South Pole will be extended
For almost ten years, scientists from all over the world have been using the large-scale experiment "IceCube" to search for neutrinos in the permanent ice of the South Pole. Neutrinos are the smallest particles that reach Earth as cosmic rays. Now the participating researchers, among them Prof. Alexander Kappes from the University of Münster, are pleased about a huge upgrade of the laboratory, which should contribute to measuring the properties of neutrinos much more accurately than before.

New Findings on Early Bombardment of the Earth and Moon and Their Development
Freie Universität Researchers Contribute to International Study Published in Nature No 215/2019 from Jul 12, 2019 How did the Earth evolve from a fireball about 4.5 billion years ago to a habitable world? The key to this question lies in the early history of our planet, when the bombardment with cosmic bodies slowly declined.

Dwarf planet Ceres: a new form of volcanism found
An international research team solves the mystery of how the mountain Ahuna Mons on Ceres was probably formed / Study in "Nature Geoscience" The scientists could hardly believe their eyes when they first saw this formation on the images acquired by their Framing Camera on board the Dawn space probe: a symmetrical mountain over 4000 metres tall and with steep, smooth sides rising over the crater-strewn surface of.

Formation of the moon brought water to earth
The Earth is unique in our solar system: It is the only terrestrial planet with a large amount of water and a relatively large moon, which stabilizes the Earth's axis. Both were essential for Earth to develop life. Planetologists at the University of Münster have now been able to show, for the first time, that water came to Earth with the formation of the Moon some 4.4 billion years ago.

EUMETSAT, Japanese space agency to cooperate on greenhouse gas monitoring
EUMETSAT and the Japan Aerospace Exploration Agency (JAXA) today signed an agreement which will result in the agencies working closely together to monitor greenhouse gases in the Earth's atmosphere. Mr Kazuo Tachi, on behalf of the Direc tor General of JAXA's Space Technology Directorate 1 Ryoichi Imai, and EUMETSAT Director-General Alain Ratier signed the agreement at a ceremony at EUMETSAT's Darmstadt headquarters today.

Astroparticle physicists observe the longest half-life ever directly measured
The universe is almost 14 billion years old. An inconceivable length of time by human standards - yet compared to some physical processes, it is but a moment. There are radioactive nuclei that decay on much longer time scales. An international team of scientists has now directly measured the rarest decay process ever recorded in a detector.

Are Brown Dwarfs Failed Stars Or Super-Planets?
Brown dwarfs fill the 'gap' between stars and the numerous smaller planets ' two very different types of astronomical objects. But how they originate has yet to be fully explained. Astronomers from Heidelberg University may now be able to answer that question. They discovered that the star Îoe Ophiuchi in the Milky Way is being orbited by two brown dwarfs, which in all probability formed along with the star from a gas and dust disk, just as planets do.

Cassini mission reveals the secrets of Saturn’s walnut-shaped ring moons
New study in in the high-ranking journal Science No 73/2019 from Mar 29, 2019 A new study of Saturn's small inner moons was published in the high-ranking journal Science . Images of Pan, Daphnis, Atlas, Pandora and Epimetheus, obtained by the Cassini spacecraft in winter 2016/17, show that several of these so-called "shepherd moons" exhibit huge ridges around their equators, giving them a very peculiar and impressing walnut-like shape (Fig.

Tidal Tails - The Beginning Of The End Of An Open Star Cluster
In the course of their life, open star clusters continuously lose stars to their surroundings. The resulting swath of tidal tails provides a glimpse into the evolution and dissolution of a star cluster. Thus far only tidal tails of massive globular clusters and dwarf galaxies have been discovered in the Milky Way system.

Unprecedented Views of the Birth of Planets
Hitherto unknown structures in belts of dust and gas around young stars are providing new insights into the birth of planets along with compelling fodder for research. They were discovered by an international team of astronomers that studied 20 of these so-called protoplanetary discs in a months-long observing campaign.

Our stellar neighbourhood expands
Astronomers from the Observatory of the University of Hamburg were involved in the discovery of a new planet. As part of an international research team led by the Institut de Ciències de l'Espai (ICE, CSIC), they have found a planet in orbit of Barnard's star. Barnard's star is a so-called red dwarf and after the Alpha-Centauri triple stellar system the second closest star to the Sun.

Mission Cassini: Nano Dust Rain from Saturn’s Rings
Findings Published in "Science" No 260/2018 from Oct 05, 2018 Nanometer-sized particles of dust are whirling in the gap between the planet Saturn and its rings, as shown by experiments following the grand finale of the Cassini spacecraft, which burned out in 2017. The particles consist of water ice and silicates, and according to the latest measurements, they come from Saturn's rings.

First evidence on the source of extragalactic particles
Research news For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by Prof. Elisa Resconi from the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
