Triton's atmosphere supports clouds of nitrogen ice crystals and a layer of organic atmospheric haze. Triton was the first Neptunian moon to be discovered, on October 10, 1846, by English astronomer William Lassell. The 1989 flyby of Triton by the Voyager 2 spacecraft remains the only up-close visit to the moon as of 2024.
Triton follows a retrograde and quasi-circular orbit, and is thought to be a gravitationally captured satellite. It was the second moon in the Solar System that was discovered to have a substantial atmosphere, which is primarily nitrogen with small amounts of methane and carbon monoxide. [26] The pressure on Triton's surface is about 14 μbar. [26]
Lunar materials could facilitate continued exploration of the Moon, facilitate scientific and economic activity in the vicinity of both Earth and Moon (so-called cislunar space), or they could be imported to the Earth's surface where they would contribute directly to the global economy. [1]
The bright blue diffraction star is Triton, Neptune's largest moon. Neptune has 16 known moons. [154] Triton is the largest Neptunian moon, accounting for more than 99.5% of the mass in orbit around Neptune, [i] and is the only one massive enough to be spheroidal. Triton was discovered by William Lassell just 17 days after the discovery of ...
Europa was discovered independently by Simon Marius and Galileo Galilei [2] and was named (by Marius) after Europa, the Phoenician mother of King Minos of Crete and lover of Zeus (the Greek equivalent of the Roman god Jupiter). Slightly smaller than Earth's Moon, Europa is made of silicate rock and has a water-ice crust [16] and probably an ...
The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube. Scientists have confirmed a cave on the moon that could be used to shelter future explorers ...
When cosmic rays enter the Earth's atmosphere, they collide with atoms and molecules, mainly oxygen and nitrogen. The interaction produces a cascade of lighter particles, a so-called air shower secondary radiation that rains down, including x-rays , protons, alpha particles, pions, muons, electrons, neutrinos, and neutrons .

Scientists have confirmed a cave on the moon, not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago.
