    A U.S. mission lands on the Moon for the first time in decades, thanks to collaboration between NASA and commercial space.

  • Biggest Holocene volcano eruption found by seabed survey

    Updated: 2024-02-22 05:45:57
    A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.

  • Early-stage subduction invasion

    Updated: 2024-02-15 16:36:15
    Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in what is known as the Wilson cycle.

  • New 'time travel' study reveals future impact of climate change on coastal marshes

    Updated: 2024-02-15 16:33:13
    A new study offers a glimpse into the possible impact of climate change on coastal wetlands 50 years or longer into the future. Scientists are usually forced to rely on computer models to project the long-term effects of rising seas, but an unexpected set of circumstances enabled a real-world experiment along the Gulf Coast.

    In anticipation of the total solar eclipse on April 8, 2024, The Planetary Society has partnered with the National Park Service to launch a new Eclipse Explorer Junior Ranger booklet.

  • Researchers studying ocean transform faults, describe a previously unknown part of the geological carbon cycle

    Updated: 2024-02-12 20:35:19
    This study reports widespread mineral carbonation of mantle rocks in an oceanic transform fueled by magmatic degassing of CO2. The findings describe a previously unknown part of the geological carbon cycle in transform faults that represent one of the three principal plate boundaries on Earth. The confluence of tectonically exhumed mantle rocks and CO2-rich alkaline basalt formed through limited extents of melting characteristic of the St. Paul's transform faults may be a pervasive feature at oceanic transform faults in general. Because transform faults have not been accounted for in previous estimates of global geological CO2 fluxes, the mass transfer of magmatic CO2 to the altered oceanic mantle and seawater may be larger than previously thought.

  • Ice cores provide first documentation of rapid Antarctic ice loss in the past

    Updated: 2024-02-08 05:20:26
    Researchers have uncovered the first direct evidence that the West Antarctic Ice Sheet shrunk suddenly and dramatically at the end of the Last Ice Age, around eight thousand years ago. The evidence, contained within an ice core, shows that in one location the ice sheet thinned by 450 meters -- that's more than the height of the Empire State Building -- in just under 200 years.

  • Ancient rocks improve understanding of tectonic activity between earthquakes

    Updated: 2024-02-08 00:51:44
    Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major earthquakes, according to a research team.

  • What turned Earth into a giant snowball 700 million years ago? Scientists now have an answer

    Updated: 2024-02-08 00:44:10
    Inspired during field work in South Australia's Flinders Ranges, geoscientists have proposed that all-time low volcanic carbon dioxide emissions triggered a 57-million-year-long global 'Sturtian' ice age.

  • A new origin story for deadly Seattle fault

    Updated: 2024-02-06 19:49:20
    The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed in a new study, could explain the fault system's earliest history and help scientists improve hazard modeling for the densely populated region.

  • Study challenges the classical view of the origin of the Antarctic Circumpolar Current and warns of its vulnerability

    Updated: 2024-02-05 21:58:46
    The Circumpolar Current works as a regulator of the planet's climate. Its origins were thought to have caused the formation of the permanent ice in Antarctica about 34 million years ago. Now, a study has cast doubt on this theory, and has changed the understanding of how the ice sheet in Antarctic developed in the past, and what this could mean in the future as the planet's climate changes.
