American Geophysical Union (AGU) Fall Meeting

The purpose of the American Geophysical Union is to promote discovery in Earth and space science for the benefit of humanity. The AGU 2018 Fall Meeting will mark another dynamic year of discovery in Earth and space science, serve as the advent of AGU’s Centennial year, and provide a special opportunity to share our science with world leaders in Washington, D.C. As the largest Earth and space…

Silicon Valley Astronomy Lecture Series: Cosmic Gold – Neutron Star Mergers, Gravitational Waves and the Origin of Heavy Elements

This Silicon Valley Astronomy Lecture Series event has passed, but a video of the lecture can be found here. Dr. Eliot Quataert of the University of California, Berkeley, will give a free, illustrated, non-technical talk. Scientists have recently developed a new way to `see' the universe, using the gravitational waves predicted by Einstein nearly a century ago. These waves can teach us about…

14th Quadrennial Solar-Terrestrial Physics Symposium

The fourteenth edition of the Solar-Terrestrial Physics symposium (STP14), which is organized by the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) and held every four years. SCOSTEP is engaged in three major activities: long-term scientific programs, capacity building and public outreach. The scientific programs are designed to advance our understanding of the solar-terrestrial …

Gravitational Waves May Solve Some Big Cosmic Riddles

There was considerable ballyhoo this week as the Royal Swedish Academy announced that the Nobel Prize in physics would go to three Americans who were prime movers in the effort to design and build LIGO, the Laser Interferometer Gravitational-Wave Observatory. This followed on the heels of an announcement that LIGO had, for the fourth time, detected the subtle flutter of space-time caused by a…

Gravity Waves and ET

The other shoe has dropped. After a century of speculation and a half-century of searching, science teams using instruments built by Caltech and MIT have made a discovery that will take up permanent residency in physics textbooks from now to the end of textbooks. They've found the gravity waves that Einstein's General Theory of Relativity predicted must pervade the cosmos. There's little doubt…

Scientist Interview - Friedemann Freund - The Future of Forecasting Earthquakes

Friedemann Freund doesn't shrink from taking on the really big problems. His research has elucidated such important phenomena as the fact that rocks under stress behave like batteries that can produce currents deep within the crust of the Earth. These are not piddling currents, either - they can be hundreds of thousand amperes, maybe as large as several million of amperes, sufficient to be…
