Scientists Weigh the Balance of Matter in Galaxy Clusters
A method of weighing the quantities of matter in galaxy clusters - the largest objects in our universe - has shown a balance between the amounts of hot gas, stars and other materials. The results are the first to use observational data to measure this balance, which was theorized 20 years ago, and will yield fresh insight into the relationship between ordinary matter that emits light and dark matter, and about how our universe is expanding.

"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.

50 years later, UChicago scientists continue to decode moon’s mysteries
Fifty years ago, NASA astronauts stepped off Apollo 11 and delivered what instantly became the most precious rock on Earth: nearly 50 pounds of dust and rock fragments from the surface of the moon. Suddenly, the wildest dreams of geoscientists had come true, as tiny pieces of the first rocks collected on another celestial body made their way to labs across the U.S. for analysis.

Hunting for
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 measure of Hubble constant adds to mystery about universe’s expansion rate
University of Chicago scientists have made a new measurement of how fast the universe is expanding-using an entirely different kind of star than previous endeavors. That value falls in the center of a hotly debated question in astrophysics that may call for an entirely new model of the universe. Scientists have known for almost a century that the universe is expanding, but the exact number for how fast it's going has remained stubbornly elusive.

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.

Super salty, subzero Arctic water provides peek at possible life on other planets
Super salty, subzero Arctic water provides peek at possible life on other planets
In recent years, the idea of life on other planets has become less far-fetched. NASA announced June 27 that it will send a vehicle to Saturn's icy moon Titan , a celestial body known to harbor surface lakes of methane and an ice-covered ocean of water, boosting its chance for supporting life. On Earth, scientists are studying the most extreme environments to learn how life might exist under completely different settings, like on other planets.

Upside-down 3D-printed skin and bone, for humans to Mars
Upside-down 3D-printed skin and bone, for humans to Mars
3D printing human tissue could help keep astronauts healthy all the way to Mars. An ESA project has produced its first bioprinted skin and bone samples. These state-of-the-art samples were prepared by scientists from the University Hospital of Dresden Technical University (TUD) , part of the project consortium together with OHB System AG as the prime contractor, and life sciences specialist Blue Horizon.

Chameleon Theory could change our thoughts on gravity
Chameleon Theory could change our thoughts on gravity
Einstein's theory of General Relativity is world famous - but it might not be the only way to explain how gravity works and how galaxies form. Physicists at Durham University created huge supercomputer simulations of the universe to test an alternative theory. Our researchers found that f(R)-gravity - a so-called Chameleon Theory - could also explain the formation of structures in the cosmos.

When CubeSats meet asteroid
When CubeSats meet asteroid
ESA's Hera mission for planetary defence, being designed to survey the smallest asteroid ever explored, is really three spacecraft in one. The main mothership will carry two briefcase-sized CubeSats, which will touch down on the target body. A French team has been investigating what might happen at that initial instant of alien contact.

Spaceship Concordia
Science for the benefit of space exploration does not only happen off planet. While some studies require the weightless isolation of the International Space Station, another location provides the right conditions for investigating the consequences of spaceflight, and it is right here on Earth. The 2018 crew of Concordia research station in Antarctica recently returned to the European Astronaut Centre in Cologne to wrap up their time as researchers and subjects at Earth's most remote outpost.

Abundance of gases in Enceladus's ocean are a potential fuel - if life is there to consume it
Abundance of gases in Enceladus’s ocean are a potential fuel - if life is there to consume it
The subsurface ocean of Saturn's moon Enceladus probably has higher than previously known concentrations of carbon dioxide and hydrogen and a more Earthlike pH level, possibly providing conditions favorable to life, according to new research from planetary scientists at the University of Washington.

Scientists use X-rays from faraway galaxy cluster to reveal secrets of plasma
Most visible matter in the universe doesn't look like our textbook picture of a nucleus surrounded by tethered electrons. Out beyond our borders, inside massive clusters, galaxies swim in a sea of plasma-a form of matter in which electrons and nuclei wander unmoored. Though it makes up the majority of the visible matter in the universe, this plasma remains poorly understood; scientists do not have a theory that fully describes its behavior, especially at small scales.

Scientists use atoms to simulate quantum physics in curved spacetimes
Black holes fascinate the public and scientists alike because they are where it all breaks down: matter, unlucky stars and space flotsam, and our understanding of physics. And while scientists have chipped away at their mysteries-from capturing the first image of one , to detecting the ripples in space-time they create when colliding-key parts of understanding black holes have escaped them.

Melting a satellite, a piece at a time
Melting a satellite, a piece at a time
Researchers took one of the densest parts of an Earth-orbiting satellite, placed it in a plasma wind tunnel then proceeded to melt it into vapour. Their goal was to better understand how satellites burn up during reentry, to minimise the risk of endangering anyone on the ground. Taking place as part of ESA's Clean Space initiative, the fiery testing occurred inside a plasma wind tunnel, reproducing reentry conditions, at the DLR German Aerospace Center's site in Cologne.

Hera asteroid mission's brain to be radiation-hard and failure-proof
Hera asteroid mission’s brain to be radiation-hard and failure-proof
At the heart of ESA's Hera mission to the double Didymos asteroids will be an onboard computer intended to be failure-proof. Designed to operate up to 490 million km away from Earth and withstanding four years of harsh radiation exposure, Hera's computer must run smoothly without locking up or crashing - on pain of mission failure, while pushing the limits of onboard autonomy.
