  • Is the Moon shrinking?

    Updated: 2024-03-25 14:00:00
    The Moon is shrinking in both actual volume and its apparent size from Earth’s perspective. We explain how scientists know this, why it happens, and how it might affect Earth.

  • New geological study: Scandinavia was born in Greenland

    Updated: 2024-03-21 20:54:19
    The oldest Scandinavian bedrock was 'born' in Greenland, according to a new geological study. The study helps us understand the origin of continents and why Earth is the only planet in our solar system with life.

  • The Planetary Society advocacy priorities in NASA’s final 2024 budget

    Updated: 2024-03-20 07:00:00
    Funding for the Near-Earth Object Surveyor, support for VERITAS, and a second lease on life for Mars Sample Return were all included in the final congressional budget for NASA in 2024.

  • From the Mediterranean into the Atlantic: The Gibraltar arc is migrating to the west

    Updated: 2024-03-19 05:31:12
    Oceans are subject to continuous change, mostly over extremely vast periods of time running into millions of years. Researchers have now used computer simulations to demonstrate that a subduction zone originating in the Western Mediterranean will propagate into the Atlantic under the Strait of Gibraltar. According to their model, this will create a new Atlantic subduction zone 50 million years into the future, which will then move down into the Earth's mantle. The new geodynamic model explains the evolution of the Gibraltar subduction zone and its likely development, which will contribute to the renewal of the Atlantic Ocean floor.

  • Even inactive smokers are densely colonized by microbial communities

    Updated: 2024-03-15 21:09:57
    Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

  • Surprising insights about debris flows on Mars

    Updated: 2024-03-14 05:21:41
    The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study.

  • Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation

    Updated: 2024-03-12 18:38:46
    Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.

  • Scientists propose new theory that explains sand ripples on Mars and on Earth

    Updated: 2024-03-12 18:38:25
    Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?

  • NASA's FY 2025 Budget

    Updated: 2024-03-12 06:00:00
    The White House proposed $25.4 billion for NASA in 2025, a modest increase from the previous year, and far less than originally planned.

    Why eclipses on Earth are unlike anything else in the Solar System.

  • New study reveals insight into which animals are most vulnerable to extinction due to climate change

    Updated: 2024-03-07 21:51:12
    In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.

  • Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks

    Updated: 2024-03-07 21:51:09
    For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'

  • The science value of Mars Sample Return

    The project has the potential to transform our understanding of the Solar System and provide evidence of life beyond Earth.

  • Geologists explore the hidden history of Colorado's Spanish Peaks

    Updated: 2024-03-04 18:57:22
    A team has collected dozens of samples from across southeastern Colorado, and their results could help to answer an enduring mystery: What made Colorado's High Plains so high?
