Scientists have succeeded in dating some of the oldest stars in our galaxy with unprecedented precision by combining data from the stars oscillations with information about their chemical composition.
New research provides the best evidence to date into the timing of how our early Milky Way came together, including the merger with a key satellite galaxy.
Using relatively new methods in astronomy, the researchers were able to identify the most precise ages currently possible for a sample of about a hundred red giant stars in the galaxy.

Scientists at the Skolkovo Institute of Science and Technology (Skoltech) and their colleagues from the University of Graz & the Kanzelhöhe Observatory (Austria) and the ESA European Space Operations Centre developed a method and software called RESONANCE to predict the solar radio flux activity for 1-24 months ahead. RESONANCE will serve to improve the specification of satellite orbits, re-entry services, modeling of space debris evolution, and collision avoidance maneuvers. The research results were published in the high-profile

DETROIT - The Department of Energy s (DOE s) Office of Science has announced the selection of 78 graduate students representing 26 states for the Office of Science Graduate Student Research (SCGSR) program s 2020 Solicitation 2 cycle.
Wayne State University Department of Physics and Astronomy graduate student David Moutard was one of the recipients for his project, Experimental Research in High Energy Physics. Moutard s research project is in conjunction with Alex Kim, Ph.D., at the Lawrence Berkeley National Lab in Berkeley, California. According to Moutard, in the very near future, the Dark Energy Spectroscopic Instrument (DESI) will begin collecting spectra of galaxies. The international DESI Time Domain Working Group will use these spectra to attempt to detect and classify transient ast
