WASHINGTON, D.C. — The Parker Solar Probe science and engineering team, a collaboration of scientists from the U.S. Naval Research Laboratory (NRL), NASA, Johns Hopkins Applied Physics Laboratory (APL), and more than 40 other partner organizations, received the 2024 Robert J. Collier Trophy, awarded by the National Aeronautic Association (NAA), on June 12.
The Vera C. Rubin Observatory has today released its long-awaited first images of the night sky, marking the beginning of the most ambitious astronomical survey in history – the Legacy Survey of Space and Time (LSST).
Kyoto, Japan -- As we witness the detrimental effects of climate change, the need for a rapid shift to renewable energy is only becoming more urgent. One of the most efficient forms of renewable energy, solar power, is generated by solar cells, which are the building blocks of solar panels. These electronic devices use semiconductors to convert the energy of light into electricity, a process called the photovoltaic effect.
Conventional solar cells have fundamental limitations in output voltage and conversion efficiency. A phenomenon called the bulk photovoltaic effect, which has attracted much attention in recent years, may enable highly efficient solar energy conversion without such limitations. However, the essential physics of the bulk photovoltaic effect have not been fully understood.
This effect originates from quantum phenomena and involves the asymmetric photoexcitation behavior of electrons, causing a steady electrical charge flow called a shift current, which is usually generated in the system with space-inversion symmetry. Another current materializes when there is a break in time-reversal symmetry, or the symmetry of physical laws when the flow of time is reversed. Since time-reversal symmetry is broken in magnetic materials, new effects related to the bulk photovoltaic effect are expected to arise in magnetic systems, but many aspects of these systems remain unexplained both theoretically and experimentally.
A new study led by scientists from the Hebrew University of Jerusalem, NASA, the Florida Institute of Technology, the Barcelona Supercomputing Center, and the University of Oxford has uncovered a connection between solar flares — sudden outbursts of radiation from stars — and short-term weather patterns on distant Earth-like planets.
An international group of astronomers led by the University of Cambridge have shown that we will be able to learn about the masses of the earliest stars by studying a specific radio signal – created by hydrogen atoms filling the gaps between star-forming regions – originating just a hundred million years after the Big Bang.
