Mars’ average surface temperature is -55 °C, but the Red Planet also experiences some variability, with temperatures ranging as high as 20 °C at the equator during midday, to as low as -153 °C at the poles. On average though, it is much colder than Earth, being just on the outer...
In 2009, NASA's Lunar Reconnaissance Orbiter found craters near the moon's south pole that are always in shadow; temperatures in these craters measured in at a balmy 33 Kelvin (minus 400 degrees Fahrenheit) — colder even than any temperature on distant Neptune.2009年，美国宇航局的月球勘测轨道...
The eighth planet from the sun and the fourth largest, with a diameter almost four times that of Earth. Neptune has a very active weather system with extremely long and powerful storms. It is the coldest planet in the solar system, with an average surface temperature of -330°F (-201°C...
Analysis of the preliminary results from the Voyager mission to the Neptune system has provided the scientific community with several methods by which the temperature of Neptune's satellite Triton may be determined. If the 37.5 K surface temperature reported by several Voyager investigations is correct...
Fluctuations in the fitted isothermal temperature values, on the order of 20K, is evident. We explore several hypotheses to explain the observed temperature variability of Neptune's stratosphere, including seasonal variability, variations in the Lyman-伪 flux received at Neptune due to the 11-year ...
So, the average temperature of the interior sun should be like 200 ﹣℃ ( 200-degree below zero), instead of millions of degree above zero. Plus, the space of the interior sun is large enough to allow the transient heat created in its core to be cooled down to 200 ﹣℃, and ...
Each analysis then consists of 20 four-second cycles, which give an average internal precision of ~0.16‰; (2 SE). The analytical session was monitored in term of stability using at least two bracketing standards (UWG-2) every 5 to 6 sample analyses. The spot-to-spot reproducibility on ...
Sites 865 and 401 demonstrate remarkable invariance and reproducibility in pre-PETM δ238UCAU, with an average of −0.36 ± 0.06‰ (2SD) that is similar to modern seawater (−0.39 ± 0.01‰; ref. 28). The simplest explanation for this uniformity is that these sites directly...
cosmochemistry by direct measurement of uranium isotopic composition. Using average meteoritic238U/235U = 137.786 ± 0.013 instead of a directly measured value would make the age of EC 002 appear 0.42 Ma younger. This change is 3.5 times larger than the uncertainty of the Pb-...
Figure 2. Average annual natural gas prices, adjusted to 2020 price levels, based on data from the2023 Statistical Review of World Energyby the Energy Institute. For the EU, the average of two price levels is used:German Average Import PriceandNetherlands TTF. For Japan, the average ofJapan...
