Lunar sample research could help protect astronauts and uncover origins of water on the moon

phys.org

Dust and rocks residing on the surface of the moon take a beating in space. Without a protective magnetosphere and atmosphere like Earth's, the lunar surface faces continual particle bombardment from solar wind, cosmic rays, and…

Neural network deciphers gravitational waves from merging neutron stars in a second

phys.org

Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods. These signals correspond to minutes of data from…

The Antarctic ozone hole is healing, thanks to global reduction of CFCs

phys.org

A new MIT-led study confirms that the Antarctic ozone layer is healing, as a direct result of global efforts to reduce ozone-depleting substances.
