Calcium silicate perovskite (CaSiO3) is arguably the most geochemically important phase in the Earth’s lower mantle, because it concentrates elements...
Using the Large Binocular Telescope and the Lowell Discovery Telescope, astronomers have conducted a comprehensive physical characterization of the near-Earth...
According to a study published in the journal Geology, samples of glassy slabs found in the Atacama Desert, northern Chile, contain tiny fragments with...
A team of researchers from the United States and Austria has analyzed remnants of ancient asteroids and modeled the effects of their violent collisions...
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...

An international team of astrophysicists has announced a new scientific project to search for evidence of potential astro-archeological artifacts or active...
Paleontologists have discovered the exceptionally well-preserved, 3.42-billion-year-old filamentous microfossils in a paleo-subseafloor hydrothermal vein...
Once the Earth was fully formed about 4.5 billion years ago, its subsequent evolution was governed by complex geophysical processes. The planet, however,...
In 2011, planetary researchers using samples of the solar wind collected by NASA’s Genesis spacecraft found that solar system planetary bodies have a...
