A Review of Neutrino Astronomy

In a white paper released earlier this week, available online here, Italian astronomers provide an historical overview of neutrino astronomy and the future observations within the field that may help the community understand a diversity of astrophysical phenomena from the Sun to supernovae. As the authors put it, they “describe the perspectives of neutrino astronomy by discussing expectations and pending problems regarding some of the best known sources of neutrinos.”

COROT Mission Completes Third Year

In a paper available online here, the European Space Agency’s (ESA) COnvection ROtation and planetary Transits (COROT) mission released a summary of its results to date. The paper also provides an excellent review of the mission and its goals, as well as its success in monitoring over 100,000 stars, and discovering some seven exoplanets. The exoplanets are reviewed and the possibilities for COROT discovering “even smaller, Earth sized planets” in its now extended mission, are discussed.

Modifying Einstein’s General Relativity to Explain Dark Energy

In a paper to be published in the International Journal of Modern Physics, available online now here, Dr. David Wiltshire proposes a modification of Einstein’s General Theory of Relativity which helps explain the enigma of dark energy. As Dr. Wiltshire puts it, “dark energy is revealed as a mis-identification of gravitational energy gradients and the resulting variance in clock rates.” As part of his modification he establishes what he calls the Cosmological Equivalence Principle which addresses the so-called Mach Principle, which is one of the things that got Einstein working on general relativity originally. Mach’s Principle is nicely summarized here, in essence it relates your local frame of reference to that of the stars.
