Researchers from Monash University's School of Earth, Atmosphere and Environment have uncovered evidence suggesting that Earth may have once had a ring system around it, dating back 466 million years. This surprising discovery comes from an analysis of asteroid impact craters and points to the existence of a debris ring during a period of intense meteorite bombardment known as the Ordovician imp

Two Russians on Friday set a record for the longest continuous stay on the International Space Station, according to Russia's space agency.
Roscosmos said Oleg Kononenko and Nikolai Chub broke the old record of 370 days, 21 hours and 22 minutes, which was set in September 2023 by Russians Sergei Prokopiev and Dmitry Petelin and American Francisco Rubio.

New NASA research reveals a process to generate extremely accurate eclipse maps, which plot the predicted path of the Moon's shadow as it crosses the face of Earth. Traditionally, eclipse calculations assume that all observers are at sea level on Earth and that the Moon is a smooth sphere that is perfectly symmetrical around its center of mass.
