Clocks, gravity, and the limits of relativity
May 27, 2019 (ESA)
Albert Einstein's general theory of relativity predicted that gravity and speed influences time, the faster you travel the more time slows down, but also the mo...
A unique experiment to explore black holes
May 27, 2019 (ESA)
Supermassive black holes, with masses ranging from millions to billions of Suns, sit at the core of most massive galaxies across the Universe. We don't know exa...
Physicists discover new type of spin waves
May 23, 2019 (SPX)
The recent discovery by physicists at Martin Luther University Halle-Wittenberg (MLU) and Lanzhou University in China offers a new route for progress on these i...
NIST team demonstrates heart of next-generation chip-scale atomic clock
May 23, 2019 (SPX)
Described in Optica, the chip-scale clock is based on the vibrations, or "ticks," of rubidium atoms confined in a tiny glass container, called a vapor cell, on ...
'Fire streaks' ever more real in the collisions of atomic nuclei and protons
May 10, 2019 (SPX)
In 2017, physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow presented a model of the phenomena occurring dur...
New Clues About How Ancient Galaxies Lit up the Universe
May 09, 2019 (JPL)
In a new study, researchers report on observations of some of the first galaxies to form in the universe, less than 1 billion years after the big bang (or a lit...
Explosions of universe's first stars spewed powerful jets
May 09, 2019 (SPX)
These first stars were likely immense, short-lived fireballs, and scientists have assumed that they exploded as similarly spherical supernovae. But now astronom...
New material also reveals new quasiparticles
May 08, 2019 (SPX)
In the symmetrically repeating unit cells of this crystal, individual atoms were offset from each other in such a way that they - as connected in the mind's eye...
First demonstration of antimatter wave interferometry
May 07, 2019 (SPX)
For antimatter the wave-particle duality had also been proven through diffraction experiments. However, researchers of the QUPLAS collaboration now established ...
Telescopes in space for even sharper images of black holes
May 07, 2019 (SPX)
Radboud University astronomers, along with the European Space Agency (ESA) and others, are putting forward a concept for achieving this by launching radio teles...
Hubble Astronomers Assemble Wide View of the Evolving Universe
May 03, 2019 (SPX)
The deep-sky mosaic, created from nearly 7,500 individual exposures, provides a wide portrait of the distant universe, containing 265,000 galaxies that stretch ...
Scientists get to the bottom of a 'spitting' black hole
May 01, 2019 (ESA)
The black hole is part of a binary system known as V404 Cygni and is sucking in material from a companion star. It is located in our Milky Way, some 8000 light-...
The search for nothing at all
Apr 30, 2019 (SPX)
The Colorado State University professor of physics studies the fundamental matter particles known as neutrinos, and an exceedingly rare instance of radioactive ...
Spinning black hole sprays light-speed plasma clouds into space
Apr 30, 2019 (SPX)
Published in the journal Nature, the research shows jets from V404 Cygni's black hole behaving in a way never seen before on such short timescales. The jets app...
IAS researchers detect evidence of 6 new binary black hole mergers within LVC data
Apr 26, 2019 (SPX)
Taking data made public by the LVC, the IAS team applied a unique set of signal processing techniques to detect these cataclysmic events, nearly doubling the to...
Hubble measurements suggest disparity in Hubble constant calculations is not a fluke
Apr 26, 2019 (SPX)
Using new observations from the NASA/ESA Hubble Space Telescope, researchers have improved the foundations of the cosmic distance ladder, which is used to calcu...
Researchers observe slowest atom decay ever measured
Apr 26, 2019 (SPX)
Their tool is the XENON1T detector, the central part of which consists of a cylindrical tank of about one meter in length filled with 3200 kilograms of liquid x...
New Hubble measurements confirm universe is expanding faster than expected
Apr 26, 2019 (SPX)
The new measurements, published April 25 in the Astrophysical Journal Letters, reduce the chances that the disparity is an accident from 1 in 3,000 to only 1 in...
SOFIA uncovers ones of the building blocks of the early Universe
Apr 24, 2019 (SPX)
As a result, the chemical model calculations associated with it were called into question. But an international team of researchers led by Rolf Gusten of the Ma...
Physicists make collimated atomic beam smaller, more precise
Apr 23, 2019 (UPI)
The technology could be used to produce exotic quantum phenomena for scientists to study or to improve devices like atomic clocks or accelerometers, a smartphon...
