Multi-messenger astronomy allows researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant.

Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune abruptly steer away from a likely death on the giant blue planet.

An international group of scientists, including Case Western Reserve University Astronomy Chair Stacy McGaugh, has published research contending that modified Newtonian dynamics (MOND) -- a rival idea to the popular dark matter hypothesis--more accurately predicts a galactic phenomenon that appears to defy the classic rules of gravity.

An international research team led by the University of Bern has discovered an exotic binary system composed of two young planet-like objects, orbiting around each other from a very large distance. Although these objects look like giant exoplanets, they formed in the same way as stars, proving that the mechanisms driving star formation can produce rogue worlds in unusual systems deprived of a Sun.

New work from an international team of astronomers improves our understanding of the most-distant known astrophysical object-- GN-z11, a galaxy 13.4 billion light-years from Earth.
