Physicists Capture the Sound of a Perfect Fluid

Physicists have observed sound waves moving through a 'perfect' fluid. The results should help scientists study the viscosity in neutron stars, the plasma of the early universe, and other ...

Scientists Peer Into the 3D Structure of the Milky Way

Scientists have helped produce a brand-new, three-dimensional survey of our galaxy, allowing them to peer into the inner structure and observe its star-forming processes in unprecedented ...

Astronomers to Release Most Accurate Data Ever for Nearly Two Billion Stars

On 3 December 2020 an international team of astronomers will announce the most detailed ever catalogue of the stars in a huge swathe of our Milky Way galaxy. The measurements of stellar position and ...

Voyager Spacecraft Detect New Type of Solar Electron Burst

The Voyager spacecraft continue to make discoveries even as they travel through interstellar space. In a new study, physicists report on the Voyagers' detection of cosmic ray electrons ...

Chaotic Early Solar System Collisions Resembled 'Asteroids' Arcade Game

One Friday evening in 1992, a meteorite ended a more than 150 million-mile journey by smashing into the trunk of a red Chevrolet Malibu in Peekskill, New York. Nearly 30 years later, a new analysis ...

Supernova Surprise Creates Elemental Mystery

Researchers have discovered that one of the most important reactions in the universe can get a huge and unexpected boost inside exploding stars known as ...

Best Region for Life on Mars Was Far Below Surface

The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a new study ...

Research Suggests Our Galaxy's Brightest Gamma-Ray Binary System May Be Powered by a Magnetar Star

A research team has shed new night on the massive star and its neutron star companion, which are thought to be at the core of the gamma-ray binary system LS ...

Astronomers developed a new method to calibrate detectors to the light from dust in our Galaxy, thereby describing a new physics, with 99.2 percent accuracy, that may show parity symmetry ...

Next Step in Simulating the Universe

Researchers have developed a way to accurately represent the behavior of elementary particles called neutrinos in computer simulations of the Universe. The simulation results reveal the effects of ...

Experiments Unravelling the Mystery of Mars' Moon Phobos

There is no weather in space - but there is weathering: Celestial bodies are bombarded by high energy particles. On the Mars moon Phobos, the situation is complicated: It is hit by particles from the ...

Earth Faster, Closer to Black Hole, in New Map of Galaxy

Earth 'just got' 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy. But don't worry, this doesn't mean that our ...

Astronomical Instrument Hunts for Ancient Metal

Researchers created a new astronomical instrument that has successfully aided in estimating the abundance of metals in the early universe. The WINERED instrument allows for better observations of ...

Fast-Moving Gas Flowing Away from Young Star Caused by Icy Comet Vaporization

A unique stage of planetary system evolution has been imaged by astronomers, showing fast-moving carbon monoxide gas flowing away from a star system over 400 light years away, a discovery that ...

Puzzling 'Cold Quasar' Forming New Stars in Spite of Active Galactic Nucleus

Using NASA's SOFIA telescope, researchers have found CQ 4479, a galaxy which never had been closely studied before, to be generating new stars in spite of a luminous AGN at the galaxy's ...

Rapid-Forming Giants Could Disrupt Spiral Protoplanetary Discs

Giant planets that developed early in a star system's life could solve a mystery of why spiral structures are not observed in young protoplanetary discs, according to a new ...

Neutrinos Yield First Experimental Evidence of Catalyzed Fusion Dominant in Many Stars

Scientists report the detection of neutrinos from the sun, directly revealing for the first time that the carbon-nitrogen-oxygen (CNO) fusion-cycle is at work in our ...

New Insights on Health Effects of Long-Duration Space Flight

Among the new findings, the research team found that chronic oxidative stress during spaceflight contributed to the telomere elongation they observed. They also found that astronauts had shorter ...

Space Travel Can Adversely Impact Energy Production in a Cell

Studies of both mice and humans who have traveled into space reveal that critical parts of a cell's energy production machinery, the mitochondria, can be made dysfunctional due to changes in ...

Blast from the Past

Astronomers have discovered that CK Vulpeculae, first seen as a bright new star in 1670, is approximately five times farther away than previously thought. This makes the 1670 explosion of CK ...
