Observations by NASA's NuSTAR X-ray telescope give astronomers new clues about the brightest and most energetic gamma-ray burst ever detected. When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Most gamma-ray bursts occur when the core of a star more massive than our Sun collapses, becoming a black hole.
The small, distant galaxy JD1 is typical of the kind that burned through hydrogen left over from the Big Bang Science + Technology The small, distant galaxy JD1 is typical of the kind that burned through hydrogen left over from the Big Bang After the Big Bang, the universe expanded and cooled sufficiently for hydrogen atoms to form.
Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass.
The structure harnesses a strange physical phenomenon and could enable engineers to manipulate light in new ways. Study: Entropy compartmentalization stabilizes open host-guest colloidal Clathrates. (DOI: 10.1038/s41557'023 -01200-6) Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers at the University of Michigan have shown how to achieve this through computer simulations.
Designing the next generation of efficient energy conversion devices for powering our electronics and heating our homes requires a detailed understanding of how molecules move and vibrate while undergoing light-induced chemical reactions.
