Scientists simulate a black hole in a water tank
Feb 07, 2019 (SPX)
This possibility is explored in a new article published in Physical Review Letters. Physicist Mauricio Richartz, a professor at the Federal University of the AB...
Why are you and I and everything else here?
Feb 04, 2019 (SPX)
In theory, there should also be large amounts of antimatter. Antimatter and matter are actually the same, only reversed in a way, with opposite charges. But the...
NASA's NICER Mission Maps 'Light Echoes' of New Black Hole
Feb 01, 2019 (SPX)
"NICER has allowed us to measure light echoes closer to a stellar-mass black hole than ever before," said Erin Kara, an astrophysicist at the University of Mary...
Superinsulators to become scientists' quark playgrounds
Feb 01, 2019 (SPX)
An international group of scientists that includes materials scientist Valerii Vinokur from the U.S. Department of Energy's (DOE) Argonne National Laboratory ha...
How does a quantum particle see the world
Feb 01, 2019 (SPX)
They can be, for example, in a quantum state of superposition of different positions at once. So, what would the description of the ball look like for an observ...
How black holes power plasma jets
Jan 30, 2019 (SPX)
The particle escapees steal some of the spinning black hole's rotational energy, accomplishing this through two main mechanisms involving magnetic fields, the s...
Active galaxies point to new physics of cosmic expansion
Jan 29, 2019 (ESA)
According to the leading scenario, our Universe contains only a few percent of ordinary matter. One quarter of the cosmos is made of the elusive dark matter, wh...
How to escape a black hole
Jan 25, 2019 (SPX)
Less understood, though, is how black holes purge energy locked up in their rotation, jetting near-light-speed plasmas into space to opposite sides in one of th...
Physicists Create the Most Accurate Model Yet of Black Hole Mergers
Jan 25, 2019 (SPX)
"Imagine taking 30 Suns and packing them into a region the size of Hawaii. Then take two such objects and accelerate them to half the speed of light and make th...
Taking magnetism for a spin: Exploring the mysteries of skyrmions
Jan 24, 2019 (SPX)
Skyrmions are nanoscale whirls or vortices of magnetic poles that form lattices within a magnetic material, a type of quasiparticle that can zip across the mate...
Birth of massive black holes in the early universe revealed
Jan 24, 2019 (SPX)
New research led by researchers from Georgia Institute of Technology, Dublin City University, Michigan State University, the University of California at San Die...
Seeing double could help resolve dispute about how fast the universe is expanding
Jan 23, 2019 (SPX)
Now, by pioneering a new way to measure how quickly the cosmos is expanding, a team led by UCLA astronomers has taken a step toward resolving the debate. The gr...
Tel Aviv University-led team discovers new way supermassive black holes are 'fed'
Jan 18, 2019 (SPX)
Despite how commonplace supermassive black holes are, it remains unclear how they grow to such enormous proportions. Some black holes constantly swallow gas in ...
New quantum structures in super-chilled helium may mirror early days of universe
Jan 18, 2019 (SPX)
The findings, to be published 16th January in Nature Communications, came after two successive symmetry-breaking phase transitions at Aalto University's Low Tem...
Las Cumbres Works with NASA, Space Station in Black Hole Discovery
Jan 18, 2019 (SPX)
In new research published in Nature Astronomy, astronomers have seen several examples of a new third kind of flare, one longer lived than a star being ripped ap...
Trillions of starts light up the dawn of the universe
Jan 17, 2019 (SPX)
Though the quasar is very far away - 12.8 billion light-years - astronomers can detect it because a galaxy closer to Earth acts as a lens and makes the quasar l...
POLAR experiment reveals orderly chaos of black holes
Jan 17, 2019 (SPX)
GRBs are short and intense bursts of gamma-rays, which suddenly appear from deep space but randomly in direction and time. They are the brightest explosions in ...
Big Bang query: Mapping how a mysterious liquid became all matter
Jan 16, 2019 (SPX)
The initial result of the Big Bang was an intensely hot and energetic liquid that existed for mere microseconds that was around 10 billion degrees Fahrenheit (5...
The orderly chaos of black holes
Jan 16, 2019 (SPX)
In order to analyse these gamma-ray bursts, researchers from the University of Geneva (UNIGE), in collaboration with the Paul Scherrer Institute (PSI) of Villig...
Birth of a black hole or neutron star captured for the first time
Jan 15, 2019 (SPX)
With the help of W. M. Keck Observatory on Maunakea, Hawaii and the University of Hawaii Institute for Astronomy's ATLAS twin telescopes, the multi-institutiona...
