Algebraic structures provide a comprehensive framework for understanding systems governed by operations such as addition and multiplication. In this context, noncommutative rings—where the order of ...

A colossal structure in the distant Universe is defying our understanding of how the Universe evolved. In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, ...

The Cassini spacecraft has obtained the most detailed look ever at Saturn’s rings, including the B ring, which has eluded previous robotic explorers. Its structure seems remarkably different from its ...

Sometimes, light curves of stars and pulsars have wonky, flickering properties, and some scientists wonder if these light curves could be caused by artificial megastructures built by advanced ...

In images made possible only as Saturn nears equinox, NASA’s Cassini spacecraft has uncovered for the first time towering vertical structures in the planet’s otherwise flat rings that are attributable ...
