The North Polar Spur and the Fan Region are two bright, large-scale radio structures that are seen on opposite sides of the sky. According to new research,...
New research led by the Observatoire astronomique de l’Université de Genève suggests that water never condensed and that, consequently, oceans never...
Nearly 63% of Afro-Arabian mammalian species went extinct approximately 30 million years ago (Oligocene epoch), after Earth’s climate shifted from swampy...
The Carnian stage (lasted from 237 to 227 million years ago) of the Triassic period marks one of the most significant intervals of the past 250 million...
New research shows that the magnetic field of our planet was relatively weak (less than half the strength of the long-term average field) for tens of millions...
In a new theoretical paper, researchers from the Santa Fe Institute provide a new perspective on the origin of life by arguing that life has emerged many...
On July 14, 2021, the Subaru-Asahi Sky Camera on the 8.2-m Subaru Telescope at the summit of Maunakea, Hawai’i, captured a rare meteor outburst associated...
