|Tiny droplets of early universe matter created|
Researchers have created tiny droplets of the ultra-hot matter that once filled the early universe, forming three distinct shapes and sizes: circles, ellipses and triangles.

Bringing balance to the universe: New theory could explain missing 95 percent of the cosmos
New research could shed light on the 'missing' dark matter and dark energy that make up 95 percent of our universe and yet are wholly invisible to us.

Macroscopic phenomena governed by microscopic physics
Researchers have observed a magnetic reconnection driven by electron dynamics in laser-produced plasmas. Magnetic reconnections are often observed in the magnetic flux on the Sun and the Earth's magnetosphere. It has been highly challenging to reveal the electron scale, microscopic information in the vast universe. Applying a weak magnetic field, where only electrons are directly coupled with the magnetic field, we observed a plasmoid and cusp-like features typical to magnetic reconnections.

All of the starlight ever produced by the observable universe measured
From their laboratories on a rocky planet dwarfed by the vastness of space, scientists have collaborated to measure all of the starlight ever produced throughout the history of the observable universe.

Gas clouds whirling around black hole form heart of distant astronomical object
Astronomers have concluded that gas clouds rapidly moving around a central black hole form the very heart of the 3C 327 quasar, confirming earlier measurements.

Earth's magnetotail: First-ever views of elusive energy explosion
Researchers have captured a difficult-to-view singular event involving 'magnetic reconnection' -- the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion -- in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Trans-galactic streamers feeding most luminous galaxy in the universe
ALMA data show the most luminous galaxy in the universe has been caught in the act of stripping away nearly half the mass from at least three of its smaller neighbors.

New finding of particle physics may help to explain the absence of antimatter
With the help of computer simulations, particle physics researchers may be able to explain why there is more matter than antimatter in the Universe. The simulations offer a new way of examining conditions after the Big Bang, and could provide answers to some fundamental questions in particle physics.

Cosmic fountain offers clues to how galaxies evolve
Galaxy evolution can be chaotic and messy, but it seems that streams of cold gas spraying out from the region around supermassive black holes may act to calm the storm.

Elusive star has origins close to Big Bang
Astronomers have found what could be one of the universe's oldest stars, made almost entirely of materials spewed from the Big Bang.

Laser blasting antimatter into existence
Antimatter is an exotic material that vaporizes when it contacts regular matter. If you hit an antimatter baseball with a bat made of regular matter, it would explode in a burst of light. It is rare to find antimatter on Earth, but it is believed to exist in the furthest reaches of the universe. Amazingly, antimatter can be created out of thin air...

Scientists refine the search for dark matter
Researchers have developed a more effective technique in the search for clues about dark matter in the universe. They can now analyze much larger amounts of the data generated at CERN.

Astronomers witness slow death of nearby galaxy
Astronomers have witnessed, in the finest detail ever, the slow death of a neighboring dwarf galaxy, which is gradually losing its power to form stars.

New insight into why galaxies stop forming stars
Galaxy clusters are rare regions of the universe consisting of hundreds of galaxies containing trillions of stars. It has long been known that when a galaxy falls into a cluster, star formation is fairly rapidly shut off in a process known as 'quenching.' A new study has made the best measurement yet of the quenching timescale, measuring how it varies across 70 percent of the history of the universe.

Gravitational waves could soon accurately measure universe's expansion
Scientists estimate that given how quickly LIGO researchers saw the first neutron star collision, they could have a very accurate measurement of the rate of the expansion of the universe within five to 10 years.

Gravitational waves could shed light on dark matter
Black holes colliding, gravitational waves riding through space-time - and a huge instrument that allows scientists to investigate the fabric of the universe. This could soon become reality when the Laser Interferometer Space Antenna (LISA) takes up operations. Researchers have now found that LISA could also shed light on the elusive dark matter particle.

Astronomers find a cosmic Titan in the early universe
Astronomers have discovered a titanic structure in the early universe, just two billion years after the Big Bang. This galaxy proto-supercluster, nicknamed Hyperion, is the largest and most massive structure yet found at such a remote time and distance.

Supermassive black holes and supercomputers
The universe's deep past is beyond the reach of even the mighty Hubble Space Telescope. But a new review explains how creation of the first stars and galaxies is nevertheless being mapped in detail, with the aid of computer simulations and theoretical models -- and how a new generation of supercomputers and software is being built that will fill in the gaps.

The state of the early universe: The beginning was fluid
Scientists recently collided Xenon nuclei, in order to gain new insights into the properties of the Quark-Gluon Plasma (the QGP). The QGP is a special state consisting of the fundamental particles, the quarks, and the particles that bind the quarks together, the gluons. The result was obtained using the ALICE experiment at the superconducting Large Hadron Collider.

New telescope almost doubles known number of mysterious 'fast radio bursts'
Astronomers have nearly doubled the known number of 'fast radio bursts'-- powerful flashes of radio waves from deep space. The team's discoveries include the closest and brightest fast radio bursts ever detected and they have proved that fast radio bursts are coming from the other side of the Universe rather than from our own galactic neighborhood.
