Pictured is a graphic showing temperatures on the moon's surface, with colder areas (dark blue) concentrated at the surface of craters The new evidence, the researchers say, comes from an analysis that combines surface temperatures with information about how much light is reflected off the moon's surface.'We found that the coldest places near the moon’s south pole are also the brightest places - brighter than we would expect from soil alone - and that might indicate the presence of surface frost,' said Elizabeth Fisher, the lead author of the study.After a year of exploration, its mission was extended.LRO spent its first three years in a low orbit collecting detailed information about the moon and its environment.Dr Siegler says there's enough evidence to warrant further investigation, and it might also help in understanding the origins of Earth's water.NASA's Lunar Reconnaissance Orbiter (LRO) is a robotic mission that set out to map the moon's surface in 2009.That study compared peak temperatures on the craters with with ultraviolet data from the Lyman-Alpha Mapping Project, or LAMP.Both the LOLA and LAMP instruments are able to measure surface brightness without sunlight - LOLA does this by measuring reflected laser light, and LAMP by measuring reflected starlight and the UV skyglow of hydrogen.
Researchers have found new evidence to suggest that some craters on the moon have frost on them.
Using data from NASA's Lunar Reconnaissance Orbiter (LRO), researchers identified bright areas in craters near the moon's south pole that are cold enough to have frost present on their surface.
The suspected frost is located in craters where temperatures are below minus 260 degrees Fahrenheit (minus 163 degrees Celsius) - conditions under which water and ice can persist for millions or billions of years.
The researchers also looked at peak surface temperatures where they observed the frost, because water ice can't last if the temperature creeps above a crucial threshold.
The findings are also consistent to another research team's analysis of LRO data in 2015.
