Stellar Demolition Derby Generates a Powerful Gamma-Ray Burst
While searching for the origins of a powerful stellar gamma-ray burst (GRB), an international team of astrophysicists may have stumbled upon a new way stars might be destroyed. Astronomers studying…
Future Ultra-Precise Timing Links to Geosynchronous Satellites
Between mountains in Hawai‘i, innovative scientists show precision timing at the quantum limit. Last year, scientists drove up Mauna Loa volcano on Hawai‘i, aimed a laser at a reflector positioned…
What Keeps Venus Looking so Young? A Powerful Jolt Early on, Perhaps
A new study suggests that higher-energy bolide impacts created a superheated core and extended volcanism on Venus — leading to its younger surface appearance. Researchers at Yale and the Southwest…
What Spinning, Flashing Stars Reveal About Gravitational Waves and Galaxies?
The Stanford physicist and astrophysicist Roger Blandford discusses new findings related to gravitational waves observed with the help of spinning, flashing stars – and what it could reveal about how…
When Extraterrestrials Call, Are We Not Spoofed?
Scientists have devised a new technique for finding and vetting possible radio signals from other civilizations in our galaxy — a major advance in the search for extraterrestrial intelligence (SETI)…
Studying Solar Flares, Sunspots Can Protect Earth
A USC Dornsife physicist explains how the Earth’s future is tied to the star it orbits. NASA’s Solar Dynamics Observatory captured this image of a solar flare on Oct. 2,…
