Construction of massive neutrino experiment kicks off a mile underground
A new era in international particle physics research officially began July 21 with a unique groundbreaking held a mile underground at the Sanford Underground Research Facility in South Dakota. Dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE), which will be built and operated by roughly 1,000 scientists and engineers from 30 countries.

Superluminous supernova marks the death of a star at cosmic high noon
The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova, one of the most distant ever discovered. The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after the big bang at a period known as 'cosmic high noon,' when the rate of star formation in the universe reached its peak.

Flashes of light on dark matter
A web that passes through infinite intergalactic spaces, a dense cosmic forest illuminated by very distant lights and a huge enigma to solve. These are the picturesque ingredients of a scientific research that adds an important element for understanding one of the fundamental components of our Universe: dark matter.

Best measure of star-forming material in galaxy clusters in early universe
The international Spitzer Adaptation of the Red-sequence Cluster Survey (SpARCS) collaboration has combined observations from several of the world's most powerful telescopes to carry out one of the largest studies yet of molecular gas -- the raw material which fuels star formation throughout the universe -- in three of the most distant clusters of galaxies ever found, detected as they appeared when the universe was only four billion years old.

Smallest particles and the vastness of the universe connected
Are density distributions of the vast universe and the nature of smallest particles related? Scientists have now revealed the connection between those two aspects, and argued that our universe could be used as a particle physics 'collider' to study the high energy particle physics. Their findings mark the first step of cosmological collider phenomenology and pave the way for future discovery of new physics unknown yet to humankind.

Shedding light on Galaxies' rotation secrets
Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals. In a new study, the researchers have traced back the dichotomy in the angular momentum of spiral and elliptical galaxies to their different formation history. In particular, the low angular momentum of ellipticals is mainly originated by nature in the central regions during the early galaxy formation process.

Hubble pushed beyond limits to spot clumps of new stars in distant galaxy
By applying a new computational analysis to a galaxy magnified by a gravitational lens, astronomers have obtained images 10 times sharper than what Hubble could achieve on its own.

How to make 'your own supernova'
Researchers are using the largest, most intense lasers on the planet, to for the first time, show the general public how to recreate the effects of supernovae, in a laboratory.

Dazzling spiral with an active heart: Barred spiral galaxy Messier 77
ESO's Very Large Telescope (VLT) has captured a magnificent face-on view of the barred spiral galaxy Messier 77. The image does justice to the galaxy's beauty, showcasing its glittering arms criss-crossed with dust lanes -- but it fails to betray Messier 77's turbulent nature.

'Little Cub' gives astronomers rare chance to see galaxy demise
A primitive galaxy that could provide clues about the early universe has been spotted by astronomers as it begins to be consumed by a gigantic neighboring galaxy.

Does dark matter annihilate quicker in the Milky Way?
A new theory predicts how dark matter may be annihilating much more rapidly in the Milky Way, than in smaller or larger galaxies and the early Universe.

Massive dead disk galaxy challenges theories of galaxy evolution
By combining the power of a 'natural lens' in space with the capability of NASA's Hubble Space Telescope, astronomers made a surprising discovery -- the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.

A unique data center for cosmological simulations
Scientists have established 'Cosmowebportal', a unique data center for cosmological simulations. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

Galaxy alignments traced back 10 billion years
The most massive galaxies in the universe have been aligned with their surroundings for at least ten billion years. This discovery shows that galaxies, like people, are influenced by their environment from a young age.

New strategy to search for ancient black holes
An interdisciplinary team of physicists and astronomers has devised a new strategy to search for 'primordial' black holes produced in the early universe. Such black holes are possibly responsible for the gravitational wave events observed by the Laser Interferometer Gravitational-Wave Observatory.

The largest virtual Universe ever simulated
Researchers have simulated the formation of our entire Universe with a large supercomputer. A gigantic catalogue of about 25 billion virtual galaxies has been generated from 2 trillion digital particles. This catalogue is being used to calibrate the experiments on board the Euclid satellite, that will be launched in 2020 with the objective of investigating the nature of dark matter and dark energy.

Cosmic inflation: Higgs says goodbye to his 'little brother'
In the first moments after the Big Bang, the Universe was able to expand even billions of billions of billions of times faster than today. Such rapid expansion should be due to a primordial force field, acting with a new particle: inflaton. From the latest analysis of the decay of mesons, carried out in the LHCb experiment by physicists from Cracow and Zurich, it appears, however, that the most probable light inflaton almost certainly does not exist.

Celestial boondocks: Study supports the idea we live in a void
A new study not only firms up the idea that we exist in one of the holes of the Swiss cheese structure of the cosmos, but helps ease the apparent disagreement between different measurements of the Hubble Constant, the unit cosmologists use to describe the rate at which the universe is expanding today.
