Physicists Directly Detect Neutrinos Created by 'Keystone' Proton-Proton Fusion Process

Using one of the most sensitive neutrino detectors on the planet, an international team of physicists including Andrea Pocar, Laura Cadonati and doctoral student Keith Otis at the University of Massachusetts Amherst report in the current issue of Nature that for the first time they have directly detected neutrinos created by the "keystone" proton-proton (pp) fusion process going on at the sun's core.

Scientists Reproduce Nucleosynthesis of Lithium

The field of astrophysics has a stubborn problem and it's called lithium. The quantities of lithium predicted to have resulted from the Big Bang are not actually present in stars. But the calculations are correct – a fact which has now been confirmed for the first time in experiments conducted at the underground laboratory in the Gran Sasso mountain in Italy.

Researchers Successfully Detect Gamma-Ray Lines

The extraordinary brightness and regularity of their light curves in the visible spectral range make type Ia supernovae valuable standardizable light sources, commonly used in modern cosmology. However, it has not yet been possible to directly measure these stellar explosions in their primary gamma radiation.

Earliest Stages of Massive Galaxy Construction Seen Through NASA Telescopes

Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.

Understanding of Quantum Laws Reaffirmed

Decades of experiments have verified the quirky laws of quantum theory again and again. So when scientists in Germany announced in 2012 an apparent violation of a fundamental law of quantum mechanics, a physicist at the University of Rochester was determined to find an explanation.

New Study Reveals the Classic Signature of a Galaxy Merger

Using the Atacama Large Millimeter/submillimeter Array (ALMA), and many other telescopes on the ground and in space, an international team of astronomers has obtained the best view yet of a collision that took place between two galaxies when the Universe was only half its current age.

Rosetta Mission Selects Landing Sites on Comet 67P/Churyumov-Gerasimenko

The European Space Agency's Rosetta mission has chosen five candidate landing sites on comet 67P/Churyumov-Gerasimenko for its Philae lander. Philae's descent to the comet's nucleus, scheduled for this November, will be the first such landing ever attempted. Rosetta is an international mission spearheaded by the European Space Agency with support and instruments provided by NASA.
