NASA’s Sophia discovered water on lunar surface

Recently, two new studies published in Nature Astronomy suggest that there may be more water on the Moon than before, including ice permanently deposited in the “cold trap” in lunar polar regions. Using data from the Stratospheric Observatory for Infrared Astronomy (SOFIA) airborne telescope, researchers have scanned the lunar surface at a more precise wavelength than six microns before, rather than three. This allows them to separate the spectral fingerprint of molecular water.
