About 35 million years ago, an asteroid hit the ocean off the East Coast of North America. Its impact formed a 25-mile diameter crater that now lies buried beneath the Chesapeake Bay. A team of researchers has obtained drilling samples from the Ocean Drilling Project site 1073 and dated them with the ''uranium-thorium-helium technique'' for the first time.

Observations of the near-Earth asteroid 2006 QV89 made on August 11, 2019 with the Canada-France-Hawaii Telescope (CFHT) have ruled out any potential future impact threat to the Earth by this asteroid for the next century.

Subsurface explorers have uncovered a previously undescribed 'Jurassic World' of around 100 ancient volcanoes buried deep within the Cooper-Eromanga Basins of central Australia.

Recent research shows that our planet may have been pummeled with asteroids long before some scientists had previously thought.

In addition to 10 years of data on the flow of heat in the Arctic ocean seafloor, researchers have published an analysis of that data using modern seismic data.

The first study of ultra-small bacteria living in the extreme environment of Ethiopia's Dallol hot springs shows that life can thrive in conditions similar to those thought to have been found on the young planet Mars. An international team of researchers lead by Dr. Felipe Gómez from Astrobiology Center in Spain (CAB (CSIC-INTA)) has found a strain of the Nanohaloarchaeles Order bacteria embedded in samples taken from a salt chimney deposited by supersaturated water at temperatures of 89 […]

Experts say scientific understanding of deep hydrocarbons has been transformed, with new insights gained into the sources of energy that could have catalyzed and nurtured Earth's earliest forms of life.

The Choiyoi magmatic Province, with an estimated volume of ~1.3 million square kilometers, represents a voluminous Permian subduction-related volcanic episode that has thus far been described only from South America. In their new paper for Lithosphere, Demian Nelson and John Cottle investigated Permian volcaniclastic rocks from central Antarctica to determine the potential magmatic source of volcanic detritus in southwestern Gondwana.

A new model built in part by a University of Alberta geophysicist contradicts a long-held idea about how the southern and central central Rocky Mountains were formed.

Whether they are found in an engagement ring or an antique necklace, diamonds usually generate quick reactions from their recipients. Now, new research shows deep inside the Earth, fast reactions between subducted tectonic plates and the mantle at specific depths may be responsible for generating the most valuable diamonds.
