Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their own characteristic masses, spin behavior, and merger rate that may be linked to different dominant formation mechanisms. The paper outlining their results was submitted to the […]

Elements essential to life, such as carbon, nitrogen, oxygen, phosphorus, and sulfur, were “delivered” to Earth and the moon during the early stages of the solar system via asteroids and comets impacting their surfaces. These exogenous materials may have provided the chemical building blocks necessary for the origin and early evolution of life on Earth. […]

Thirty-four years after Cornell University scientists first conceived it, the Fred Young Submillimeter Telescope (FYST) now rises above the Atacama Desert, near the summit of Cerro Chajnantor in Chile. FYST will help answer some of the most important questions in astronomy, including how the universe works, the nature of dark energy and dark matter, how […]

Their dramatic grand finale fast approaching, Artemis II’s astronauts aimed for a splashdown in the Pacific on Friday to close out humanity’s first voyage to the moon in more than half a century.
