NASA's LRO Spacecraft Detects Promising Room Temperature Moon Lava Holes

Credit: NASA/Goddard Space Flight Center/Arizona State University NASA’s Lunar Reconnaissance orbiter (LRO) has discovered a crater hole near the Moon’s Sea of ​​Tranquility at room temperature. An LRO onboard thermal imager found that a 328-foot depression about the length and width of a football field had overshadowed an area that maintained a constant, cool temperature of around 63 degrees Fahrenheit. The hope is that future astronauts will be able to use such a hole as a shelter from the extreme temperatures of the lunar surface that can fluctuate between 260 degrees Fahrenheit on lunar days and cold to minus 280 degrees Fahrenheit on lunar nights. First discovered on the Moon in 2009, such holes, subsurface lava tunnels, and caves can also offer protection from cosmic rays, solar radiation, and micrometeo...

When the weather is hot, and the material is in the HS (white) state, light is reflected and the increase in room temperature is controlled. In contrast, under cold temperatures, the material exhibits the LS state (pink), so more wavelengths are absorbed and the room gets hotter. c) Illustration of rotational transition under external stimuli.

New model predicts how temperature affects life from quantum to classical scale

Every biological process is highly dependent on temperature. This applies to the very small, the very large, and every scale in between, from molecules to ecosystems and in every environment. A general theory explaining how life depends on temperature is lacking — until recently. In a paper published in the Proceedings of the National Academy of Sciences, researchers led by Jose Ignacio Arroyo, a Santa Fe Institute Postdoctoral Fellow, introduce a simple framework that strictly predicts how temperature affects living things, at all scales. “This is very basic,” says SFI External Professor Pablo Marquet, an ecologist at the Pontifica Universidad Catolica de Chile, in Santiago. Marquet, Ph.D. thesis advisor, is also working on the model. “You can apply this to almost any process that is affected by temperature. We hope this will be an important contribution.” Marquet noted that such a theory could help researchers make accurate predictions in a variety of areas, including biologica...
