  • Sensitive instruments reveal methane beneath the Arctic Ocean for the first time.
  • The gas is released in cycles that correspond to the tides.
  • Rising warming oceans may help to contain the greenhouse gas.

  • A new study says solar and lunar tide impacts led to the evolution of bony fish and tetrapods.
  • The scientists show that tides created tidal pools, stranding fish and forcing them to get out of the water.
  • The researchers ran computer simulations to get their results.

  • Scientists have long thought that water exists on the lunar surface, but it wasn't until 2018 that ice was first discovered on the moon.
  • A study published Monday used NASA's Stratospheric Observatory for Infrared Astronomy to confirm the presence of molecular water..
  • A second study suggests that shadowy regions on the lunar surface may also contain more ice than previously thought.

Scientists may have solved the mystery of how the moon was magnetized

New research explains why the Moon's crust is magnetized by debunking one long-standing theory.

  • Researchers used advanced computer simulations to study the effect of meteoroid impacts on the Moon's surface.
  • The study shows that such impacts were unlikely to cause the magnetization observed in the lunar crust.
  • An ancient core dynamo is the most likely explanation for the Moon's magnetic field from about 4 billion years ago.

    • In the 1970s NASA published an extensive book on urban planning in space.
    • Acclaimed architectural and engineering firm Skidmore, Owings & Merrill LLP (SOM) designed a conceptual plan for the first permanent settlement for human life on the moon.
    • An MIT team developed a concept for the first sustainable cities on Mars to be built in the next century.
