Topographic depressions within permanently shadowed regions (PSRs) on low-obliquity planetary bodies can be shielded not only from direct illumination, but also from scattered sunlight and thermal emission from nearby sunlit surfaces. We apply an illumination model to high-resolution topography data to produce the first map of double shadows at the lunar poles. The total doubly shadowed area resolved at the 30 m scale is 1.47 km2 in the northern hemisphere and 5.37 km2 in the southern hemisphere, predominantly contained within small craters on the floors of large permanently shadowed craters. In total, ∼0.04% of PSR area is permanently double shadowed, but the largest double shadows are nearly 600 m across, potentially large enough to be resolved in remote sensing temperature measurements. In the absence of secondary heating sources, double shadows are predicted to be significantly colder than singly shadowed areas and could sequester highly volatile compounds like carbon dioxide. Future in situ investigation of the regions identified in this work can elucidate the origin and distribution of the Moon's most volatile deposits.

As indicated by the title of Robert Heinlein's 1966 novel The Moon is a Harsh Mistress, the Moon is a harsh environment to operate in. There is a scant atmosphere, abrasive dust, and extreme temperature ranges to deal with. Observed temperatures range from a blistering 127 C (260 F) in equatorial su
Some of these craters are home to permanently shadowed regions that haven't seen sunlight in billions of years and experience temperatures as low as -334°F (-203°C).What is the temperature of permanently shadowed regions? ›
Permanently shadowed regions have a stable surface temperature. On the Moon, the temperature hovers somewhere at or below 50 Kelvin. Another temperatures estimate is 25 K to 70 K. The low temperatures make the regions desirable locations for future infrared telescopes.What is a permanently shadowed region? ›
The Moon's axis tilts only 1.5 degrees from the ecliptic plane (the plane containing the path of the Earth and the Moon around the Sun). Because of this unique geometry, sunlight never shines on the floors of some craters near the Moon's poles (figure 1). These areas are known as Permanently Shadowed Regions, or PSRs.What is the permanently shaded region of the Moon? ›
Permanently shadowed regions, or PSRs, are areas near the north and south poles of the Moon that never receive direct sunlight and thus are extremely cold (25 K to 70 K; -415°F to -334°F). Even though PSRs are exposed to the vacuum of space, water ice and other volatiles (ammonia, methane, etc.)What is the temperature in the shadows of the Moon? ›
In deep craters near the Moon's poles, permanent shadows keep the surface even colder — NASA's Lunar Reconnaissance Orbiter has measured temperatures lower than -410°F (-246°C). These forever-dark places harbor ice deposits that may be billions of years old.What is the temperature in shadow? ›
The shade doesn't make temperatures cooler. This is all because the temperature you feel in the shade is the actual air temperature. Being in direct sunlight can make the air feel 10-15 degrees warmer than it actually is because of the sun's rays touching your skin.What is the temperature in the shadow of the Earth? ›
If you were an astronaut on the International Space Station, when you were on the dark side of the Earth in the Earth's shadow, the temperature outside would be a chilly -150 degrees. Freezing! (Well, 150 degrees below freezing.)What are permanently shadowed regions at the poles for Mercury and the Moon called? ›
Large craters with terraced rims block sunlight from ever reaching inside. These areas deprived of sunlight are aptly called permanently shadowed regions, or PSRs. The Moon has hundreds of PSRs on its poles.What is the temperature of the lunar PSR? ›
The permanently shadowed regions (PSRs) at the lunar poles represent the coldest areas yet observed in the Solar System. The Diviner instrument on the Lunar Reconnaissance Orbiter (LRO) has recorded temperatures as low as -238 C (-397 F) within the south pole PSRs.Is there a permanent Dark Side of the Moon? ›
The moon is tidally locked with Earth, which means that we are always looking at the same side of it. The other side — the far side — isn't visible to us, but it's not in permanent darkness.
These areas are called permanently shadowed regions, or PSRs. PSRs are known to exist on other low-gravity, airless worlds too, like Mercury and Ceres. Temperatures inside the Moon's PSRs can drop to -250 degrees Celsius (-418 degrees Fahrenheit). That's colder than Pluto!What is the completely dark inner area of the shadow of the Earth or moon called? ›
The dark, inner shadow of planet Earth is called the umbra. Shaped like a cone extending into space, it has a circular cross section most easily seen during a lunar eclipse.What is the shading on the Moon? ›
However, there are some parts of the Moon that never see sunlight. These areas are called permanently shadowed regions, and they appear dark because unlike on the Earth, the axis of the Moon is nearly perpendicular to the direction of the sun's light.What is the minimum temperature on the Moon? ›
Taking the Moon's Temperature
Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon's poles are even colder.
In certain spots near the moon's poles temperatures can drop even further, reaching - 424° F (- 253°C or 20 K) according to NASA. One reason for these dramatic extremes is that the moon has no lunar atmosphere to insulate heat.What happens to the temperature as the Earth is covered by the Moon shadow? ›
In general, the temperature may drop slightly during a total solar eclipse as the Moon blocks the Sun's direct radiation and casts a shadow on the Earth's surface.Are high temperatures taken in the shade? ›
All temperatures taken for records of air temperature are taken in the shade. Any temperature gauges that are recording temperatures in the sun will be affected by the sun's radiation and the temperature during that period will appear significantly hotter.Are temperatures recorded in the shade? ›
Temperatures are always measured in the shade because the "shade temperature" is the true air temperature. When sunlight shines through clear, cloud-free air, its energy is not significantly absorbed because clear air is quite transparent to sunlight.How cold is background radiation? ›
The universe has been expanding since the Big Bang. This background radiation emitted 380,000 years later has cooled to 2.728 Kelvin (−270.42°C). It can be observed in the microwave range with radio telescopes or satellites.
