Milky Way radio waves can be seen as a bright splash of yellow reflected on the moon’s surface in a new image. Astronomers used data from the Murchison Widefield Array in Australia to create the image and plan to use the technique to learn more about the evolution of the early universe.

Subduction zones drag down large amounts of water

Scientists used seafloor and island seismographs to estimate how much water is pulled underground by tectonic-plate collisions in the western Pacific’s Mariana Trench. After listening to earthquake and other noises from over a year, researchers concluded that subduction zones move about three times more water into Earth’s interior than previously thought.
