Enduring ‘radio rebound’ powered by jets from gamma-ray burst

IMAGE: ALMA's time-lapse movie showing the "afterglow " of a powerful gamma-ray burst. These images of the millimeter-wavelength light reveal details about the energy in the GRB's jets.... view more  Credit: ALMA (ESO/NAOJ/NRAO), T. Laskar; NRAO/AUI/NSF, S. Dagnello In the blink of an eye, a massive star more than 2 billion light-years away lost a million-year-long fight against gravity and collapsed, triggering a supernova and forming…

Galaxy outskirts likely hunting grounds for dying massive stars and black...

Findings from a Rochester Institute of Technology study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are new places to observe gravitational waves created when the massive bodies collide, the authors report. The study winds back time on massive black holes by analyzing their visible precursors--supernovae with collapsing cores. The slow decay of these massive stars creates…

Possible death of the universe scenario proposed

The red dot indicates the point (x1,x2)=(?1,0).... view more  Credit: Kazan Federal University Professor Odintsov comments, "Possible future singularity was studied within the modified theory of gravity with the use of dynamical system variables. We showed that a dynamical system singularity is not always a physical singularity.…

A domestic electron ion collider would unlock scientific mysteries of atomic...

WASHINGTON - The science questions that could be answered by an electron ion collider (EIC) - a very large-scale particle accelerator - are significant to advancing our understanding of the atomic nuclei that make up all visible matter in the universe, says a new report by the National Academies of Sciences, Engineering, and Medicine. Beyond its impact on nuclear science, the advances made possible by…

NASA analyzes tropical storm Wukong’s strawberry-shape

IMAGE: NASA's Aqua satellite revealed some cloud top temperatures in fragmented thunderstorms as cold or colder than minus 70 degrees (red) Fahrenheit (minus 56.6 degrees Celsius) on Tropical Depression Carlotta on... view more  Credit: NASA/NRL Infrared satellite imagery provides temperature data, and when NASA's Aqua satellite passed over Tropical Storm Wukong, the coldest cloud tops circling the center resembled a strawberry and leaf. Cloud top temperatures…
