First rock dating experiment performed on Mars
Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments—like analyzing meteorites and moon rocks—have always been done on Earth. Now, for the first time, ...
Searching for cosmic accelerators via IceCube
In our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider (LHC) at CERN. Scientists don't know what these cosmic accelerators are or where they are located, ...
Black hole birth captured by cosmic voyeurs
Intelligent telescopes designed by Los Alamos National Laboratory got a front row seat recently for an unusual birth.
NASA instrument determines hazards of deep-space radiation
Deep-space radiation is a significant danger for interplanetary human space flight. But now an instrument on NASA's Lunar Reconnaissance Orbiter (LRO) has learned more than ever before about the high-energy ...
UNH scientists document, quantify deep-space radiation hazards
Scientists from the University of New Hampshire and colleagues have published comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA's Lunar Reconnaissance Orbiter (LRO). ...
South Pole telescope detector aids study of the universe
Center for Nanoscale Materials (CNM) users from Argonne's High Energy Physics and Materials Science divisions helped design and operate part of the South Pole Telescope, a project that aims a large telescope ...
Cosmic rays zap a planet's chances for life
Mysterious cosmic rays constantly bombard Earth from outer space. Now scientists find these energetic particles could limit where life as we know it might exist on alien planets.
Solar activity playing a minimal role in global warming, research suggests
Changes in solar activity have contributed no more than 10 per cent to global warming in the twentieth century, a new study has found.
Researchers shed new light on dark energy, cosmic speed-up
In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion.
Suzaku study points to early cosmic 'seeding'
(Phys.org) —Most of the universe's heavy elements, including the iron central to life itself, formed early in cosmic history and spread throughout the universe, according to a new study of the Perseus Galaxy ...
Swarm launch postponed
The launch of ESA's magnetic field mission from Plesetsk, Russia, has been postponed by about a week.
South Pole Telescope helps Argonne scientists study earliest ages of the universe
(Phys.org) —For physicist Clarence Chang at the U.S. Department of Energy's (DOE) Argonne National Laboratory, looking backward in time to the earliest ages of the universe is all in a day's work.
ALMA reveals ghostly shape of 'coldest place in the universe'
At a cosmologically crisp one degree Kelvin (minus 458 degrees Fahrenheit), the Boomerang Nebula is the coldest known object in the Universe – colder, in fact, than the faint afterglow of the Big Bang, ...
Europe's Planck telescope retires
The deep-space Planck telescope was switched off Wednesday after a successful 4.5-year mission that revealed our Universe to be 80 million years older than previously thought, the European Space Agency said.
