15. Triton – A Massive Space Volcano
Scientists widely consider Triton, a moon that orbits Neptune, to be a trapped Kuiper Belt body, which is held in its place within the orbit because of the mighty gravitational pull erupting from Neptune. Triton has a thin layer of atmosphere that is brimming with methane and nitrogen, which are created due to the volcanic eruptions occurring on the surface of the moon.
The 1989, the Voyager 2 space probe mission discovered geysers being emitted from the cold and scaly surface of the moon, and the team was surprised to find such an unpredictable feature on this cantaloupe of an object. Images captured of the southern pink cap managed to reveal this peculiar and rare characteristic by identifying the dark smears on the surface, left by the carbon-loaded emissions.
Triton is one of the very less remaining active volcanic objects within the Solar system, and it is located at a striking 4.5 billion km away from the sun. It is one of the coldest places in the universe, and most of its concentration of nitrogen has frozen, which has endowed Triton with a super reflective surface.
16. Titan – The Second Largest Moon
Titan, another moon that orbits Saturn, is regarded as the second largest moon, and it only lost the title of being the largest to Ganymede by the difference of a minor 2%. Scientists reveal that Titan is the only moon in the solar system that features a thick cloud of atmosphere, which is thick enough to completely shroud up the solid core of the planet’s surface by massive clouds of nitrogen and methane.
When the UV rays from the sun reach its atmosphere, a reaction is triggered amongst these gases, giving birth to various distinctive organic molecules that are found in a multitude of traces within the atmospheric layer.
The Cassini space probe mission discovered that Titan contains various rivers and lakes filled with methane and ethane, and these water bodies are filled up with the rains emerging from orange clouds along with dark sandy dunes that are made up with hydrocarbon grains.
The most peculiar and strikingly different aspect from earth is the fact that any kind of volcanic activity on Titan is more likely to create water rather than molten rocks. Titan’s surface also boosts several mountains, which have been named after the mountains discovered in Middle Earth.
17. Io – The Feisty Moon
Io is the third largest moon that orbits around Jupiter, and it is widely considered as the most volcanic celestial object within the solar system. It is compelled to orbit around the same path carved out by bigger moons, such as Europa and Ganymede, and it is always facing the planet from the same side. Its elliptical orbit is the reason behind its abundance of heat.
The altering gravitational pull of Io creates staggering tidal forces, which cause the otherwise solid surface of this moon to gravitate and bulge outwards, sometimes as great as 100m. Therefore, the subsurface of 10 appears to be entirely molten, and the erupting matter of its volcanoes has been reported to have gone as high as 190 miles towards the atmosphere, flooding over the impact craters and creating liquid rock floodplains and lakes of lava.
The surface of Io is constantly being renewed and regenerated, and scientists are unsure whether the surface composition is made of sulfur, which keeps altering its shades, or silicon, which is capable of bearing the constant heat.
