Observatory detects extragalactic cosmic rays hitting the Earth

Fri, 22 Sep 17 00:03:10 -0700

Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high energy cosmic rays -- whether they came from our galaxy or outside the Milky Way. The answer is a galaxy or galaxies far, far away, according to a report published Sept. 22 in Science by the Pierre Auger Collaboration.



Study confirms cosmic rays have extragalactic origins

Thu, 21 Sep 17 00:12:20 -0700

International collaboration by scientists with the Pierre Auger Observatory confirms that most of the highest energy cosmic rays that reach the Earth come from outside the Milky Way galaxy.



Is the Milky Way an 'outlier' galaxy? Studying its 'siblings' for clues

Wed, 20 Sep 17 00:03:10 -0700

The most-studied galaxy in the universe -- the Milky Way -- might not be as 'typical' as previously thought, according to a new study. Early results from the Satellites Around Galactic Analogs (SAGA) Survey indicate that the Milky Way's satellites are much more tranquil than other systems of comparable luminosity and environment. Many satellites of those 'sibling' galaxies are actively pumping out new stars, but the Milky Way's satellites are mostly inert, the researchers found.



New supernova analysis reframes dark energy debate

Wed, 13 Sep 17 00:01:10 -0700

The accelerating expansion of the Universe may not be real, but could just be an apparent effect, according to new research published in the journal Monthly Notices of the Royal Astronomical Society. The new study -- by a group at the University of Canterbury in Christchurch, New Zealand -- finds the fit of Type Ia supernovae to a model universe with no dark energy to be very slightly better than the fit to the standard dark energy model.



Ultraviolet light from superluminous supernova key to revealing explosion mechanism

Thu, 07 Sep 17 00:12:50 -0700

An international team of researchers led by Kavli IPMU's Alexey Tolstov and Ken'ichi Nomoto have discovered a way to use UV light from superluminous supernovae to uncover its explosion mechanism, and used it to identify Gaia16apd as a shock-interacting supernova, reports a new study.



Exchanges of identity in deep space

Thu, 07 Sep 17 00:15:00 -0700

By reproducing the complexity of the cosmos through unprecedented simulations, a new study highlights the importance of the possible behaviour of very high energy photons. In their journey through intergalactic magnetic fields, they could be transformed into axions and thus avoid being absorbed



Climate change for aliens

Thu, 07 Sep 17 00:00:10 -0700

For more than 50 years, the Kardashev scale has been the gold standard for classifying hypothetical 'exo-civilizations' by their ability to harness energy. A team of researchers led by Rochester astrophysicist Adam Frank have devised a new system that takes into account the impacts of that energy use.



Does the organic material of comets predate our solar system?

Wed, 06 Sep 17 00:12:00 -0700

The Rosetta space probe discovered a large amount of organic material in the nucleus of comet 'Chury.' In an article published by MNRAS on Aug. 31, 2017, two French researchers advance the theory that this matter has its origin in interstellar space and predates the birth of the solar system.



Stanford professor tests a cooling system that works without electricity

Tue, 05 Sep 17 00:16:00 -0700

Stanford scientists cooled water without electricity by sending excess heat where it won't be noticed -- space. The specialized optical surfaces they developed are a major step toward applying this technology to air conditioning and refrigeration.



UCLA physicists propose new theories of black holes from the very early universe

Fri, 01 Sep 17 00:05:50 -0700

'Primordial black holes,' believed to have formed shortly after the Big Bang, might explain how heavy elements such as gold, platinum and uranium came to be, UCLA physicists report.



Stellar corpse sheds light on origin of cosmic rays

Fri, 01 Sep 17 00:09:40 -0700

New research revealed that the entire zoo of electromagnetic radiation streaming from the Crab nebula -- one of the most iconic objects in the sky -- has its origin in one population of electrons and must be produced in a different way than scientists have traditionally thought. The results have implications for our understanding of how cosmic rays attain their incredible energies.



Researchers propose how the universe became filled with light

Wed, 30 Aug 17 00:07:00 -0700

University of Iowa researchers have a new explanation for how the universe changed from darkness to light. They propose that black holes within galaxies produce winds strong enough to fling out matter that punctures holes in galaxies, allowing light to escape.



Artificial intelligence analyzes gravitational lenses 10 million times faster

Wed, 30 Aug 17 00:11:40 -0700

Researchers from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have for the first time shown that neural networks -- a form of artificial intelligence -- can accurately analyze the complex distortions in spacetime known as gravitational lenses 10 million times faster than traditional methods.



Magnetic fields in distant galaxy are new piece of cosmic puzzle

Wed, 30 Aug 17 00:16:00 -0700

Astronomers have measured magnetic fields in a galaxy 4.6 billion light-years away -- a big clue to understanding how magnetic fields formed and evolved over cosmic time.



Record-breaking galaxy 5 billion light-years away shows we live in a magnetic universe

Mon, 28 Aug 17 00:07:30 -0700

A team of astronomers has observed the magnetic field of a galaxy five billion light-years from Earth. The galaxy is the most distant in which a coherent magnetic field has been observed and provides important insight into how magnetism in the universe formed and evolved.



VLA reveals distant galaxy's magnetic field

Mon, 28 Aug 17 00:06:40 -0700

A chance combination of a gravitational lens and polarized waves coming from a distant quasar gave astronomers the tool needed to make a measurement important to understanding the origin of magnetic fields in galaxies.



Scientists take first snapshots of a molecular propeller that runs at 100 degrees Celsius

Thu, 24 Aug 17 00:03:40 -0700

Scientists have made a crucial new discovery into how a group of ancient microbes that can survive in some of the world's harshest environments, propel themselves forward.



UChicago scientists detect first X-rays from mystery supernovas
A team of scientists, including scholars from the University of Chicago, appear to have found the first X-rays coming from type Ia supernovae. Their findings are published in the
