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.
For the first time, lithium has been identified and measured in the atmosphere of a white dwarf. The finding, reported by the University of North Carolina at Chapel Hill, provides clues for what's become of the lithium expected from the Big Bang.
Combining signals from multiple observations of neutron stars has allowed researchers to better understand the properties of ultra-dense matter and constrain the Hubble constant, which describes how fast the Universe is expanding, according to a new study.
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.
An astro-statistics course UC Riverside graduate student Remington Sexton took three years ago taught him techniques that led him to develop free, open-source code benefiting astronomers everywhere. Called BADASS, the code is unique in that it provides a way for astronomers to fit the stellar motions of stars simultaneously with many other components, is written in a popular programming language, and is versatile enough to fit not just active galactic nuclei but also normal galaxies.
An MIT-designed atomic clock uses entangled atoms to keep time even more precisely than its state-of-the-art counterparts. The design could help scientists detect dark matter and study gravity's effect on time.
