Tin-100 produced in key nuclear physics experiment
A few minutes after the Big Bang the universe contained no other elements than hydrogen and helium. Physicists of the Technische Universitaet Muenchen and the Helmholtz Center for Heavy Ion Research have now ...
Stephen Hawking to turn 70, defying disease
British scientist Stephen Hawking has decoded some of the most puzzling mysteries of the universe but he has left one mystery unsolved: How he has managed to survive so long with such a crippling disease.
Discovery poses challenge to galaxy formation theories
A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest that they may have formed relatively recently. This would run counter to the widely-held belief ...
Higgs Boson makes it a champagne year for physics
2012 will go down in history as a landmark year, when physicists discovered a fundamental particle that may answer one of the greatest riddles of all.
Researchers' data are closing in on Higgs boson particle
Scientists at the world's largest atom smasher say they have reams of new data that will reveal with greater certainty whether they have already glimpsed a long-sought theoretical particle that could help ...
Galaxies in the thick of it grow up fast
In a quest to learn more about our own galaxy, a Sydney astronomer has identified dozens of previously unknown galaxies in a distant cluster.
The earliest stars in the Universe
(PhysOrg.com) -- Matter in the universe after the big bang consisted almost entirely of hydrogen and helium atoms. Only later, after undergoing fusion reactions in the nuclear furnaces of stars, did these ...
Researchers Shed Light on Birth of the First Stars
(PhysOrg.com) -- In the beginning, there were hydrogen and helium. Created in the first three minutes after the Big Bang, these elements gave rise to all other elements in the universe. The factories that ...
Researchers build computer simulation that shows a way to detect the birth of the first stars
Searching for defects in space
Topological defects in space may have developed fractions of a second after the Big Bang. Simulations of these wormlike entities and a comparison of the simulations with cosmic background radiation measurements ...
Fundamental matter-antimatter symmetry confirmed
International collaboration including MPQ scientists sets a new value for the antiproton mass relative to the electron with unprecedented precision.
Black holes from the dawn of the universe
The "Dark Ages" of the universe started about 400,000 years after the big bang, after matter cooled down enough for neutral atoms to form.
Rumours fly that gravitational waves have been detected
Last week the Harvard-Smithsonian Center for Astrophysics (CfA) stated rather nonchalantly that they will be hosting a press conference on Monday, March 17th, to announce a "major discovery." Without a potential ...
Carbon, carbon everywhere, but not from the Big Bang
As Star Trek is so fond of reminding us, we're carbon-based life forms. But the event that jump-started the universe, the Big Bang, didn't actually produce any carbon, so where the heck did it and we come from? ...
