The Sun's gravitational pull extends farther than Neptune, all the way to the Kuiper Belt and beyond. For these dark and mysterious moons, the sun is just a needle in the sky, but the most mysterious of them is Pluto. Here is Unveiled (a magazine or broadcast platform). Today we're going to talk about an unusual topic: What's hidden on Pluto? Are you often curious about this? Subscribe to Unveiled for more interesting knowledge like that! In 2006, Pluto was removed from the nine planets, and Pluto was downgraded from "planet" to "dwarf star".
The International Astronomical Union decided that to count as a planet, an object "must clear its orbital neighbors," which Pluto failed to do because of its relatively small mass. Strictly speaking, Pluto is a "trans-Neptune object" floating in the Kuiper Belt. It was the discovery of another similar object, Eris, that led to a change in the definition of "planet.". Pluto's surface area is only 3.3% of Earth's size, making it roughly the same size as Russia.
In addition to being small in size, Pluto's gravitational pull is so small that you'll hardly notice it — about 6.3 percent of Earth's gravitational pull. Still, it does have its own satellites: Charon, Styx, Hydra, Knicks, and Three-Headed Dogs. It wasn't until nearly fifty years after Pluto itself was discovered that the largest Charon was discovered in 1978. Because of its size, Pluto and Charon are almost classified as binary planets.
The two are tidally locked in, so they always present the same side to each other. Charon's pulling force causes Pluto's football-shaped satellites, the Knicks and Hydra, and possibly stex and three-headed dogs, to wobble as they spin, thus getting caught in a gravitational tug-of-war. This small amount of data we have was collected by the New Horizons probe in 2015, and we won't have any more news until there is a further breakthrough.
Amazingly, while we've been able to detect planets, stars, and black holes millions of light-years from Earth, there are still things in our own solar system that we don't understand. For thousands of years, there was no way to study other celestial bodies except the seven "classical planets"—the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. Obviously, we now know that neither the Sun nor the Moon are planets, but this ancient definition of "planet" refers to objects that are visible to the naked eye.
Until the discovery of Uranus in 1781, a celestial body that had been mistaken for a star, we didn't know how vast the solar system was. In 1846, more than 60 years later, Neptune was discovered; in 1930, astronomer Clyde Tombaugh discovered Pluto. Prior to this, due to the apparent perturbation of Uranus' orbit, the hypothesis of the existence of another planet had been proposed, which later became one of the factors in the overestimation of Neptune's mass.
Although Pluto may no longer be a planet, its discovery is still very important because it was the first extra-Neptune object ever discovered by humans. It wasn't until 1992 that a second Neptune alien, asteroid 15760, was discovered. Part of the reason why studying extraterrestrial bodies from Pluto and Neptune is that we are absolutely far away from them. The distance between Earth and Pluto is between 2.66 billion and 4.67 billion miles, compared with sometimes Mars being only 34 million miles away from Earth.
The huge distance makes it very difficult for humans to send probes to Pluto, and the fact that the probes may reach Pluto one day; if the best time to send is missed, it may even cause the probe to fly a distance of double. In addition, considering that Pluto will take 248 years to orbit the Sun, it may take a long time to have a second chance of sending. In fact, since Pluto's discovery, it hasn't even completed half of its journey around the Sun.
So far, the only man-made object to reach Pluto is NASA's New Horizons probe, which flew over Pluto's surface in 2015. It detected an unexpectedly "youthful" surface and a rich and diverse topography. This includes bizarre ice flows, mountains, and some evidence of the existence of ice volcanoes. A large expanse of smoke envelops Pluto, and these fumes are particles produced by sunlight breaking down methane gas. Pluto's plains are mostly ice made of nitrogen condensation, but its mountains are ice condensed from water and frost from methane gas.
A dark red band called Cthulhu Macula hovers around the surface of Pluto, which may be due to Tholins, an organic compound formed when ultraviolet light irradiates methane and nitrogen. Perhaps the best adjective to describe Pluto, apart from "distant," is "cold." Pluto's surface temperature is incredibly low, at its highest at minus 369 degrees Fahrenheit and as low as minus 387 degrees Fahrenheit, although this is higher than the average temperature in outer space itself (around minus 454 degrees Fahrenheit). But that's still much lower than the coldest temperature on Earth since recorded (minus 128.6 degrees Fahrenheit recorded in Antarctica in 1983).
Pluto is almost three times colder than antarctica at its coldest, specifically, where liquid nitrogen is about -320°C. Even at the warmest of Pluto' days, if you are exposed to the surface of Pluto without any protection, the surface temperature of Pluto can still freeze the human body.
Pluto is definitely one of the most unlivable places in the solar system, and living on Pluto will face the same or worse problems as living on the Antarctic research station or the International Space Station: astronauts and Antarctic expeditions are mostly scientists and soldiers, but even they cannot stay in their respective bases in isolation for a long time; the ubiquitous radiation and low gravity environment in the International Space Station are the biggest limits for astronauts to stay in outer space. The world's longest single stay in outer space is now held by Russian cosmonaut Valeri Polyakov for 437 days; what is even more deadly is that Pluto's atmosphere is made up of large amounts of nitrogen and toxic carbon monoxide.
Needless to say, first of all, our technology must develop by leaps and bounds to send people to Pluto, not to mention the establishment of some kind of research station-like base or the opportunity to return. Even in the technologically advanced future, Pluto is unlikely to be a scientific research base, as antarctica is, even though it has seen a wide variety of tourists. Unless fuel-filled spacecraft are available, any attempt to establish large-scale settlements on Pluto for purposes other than planetary research is difficult and high-risk.
But Pluto may not be as desolate as it was when it first saw it. There are many frozen planets in the solar system that scientists now believe exist in the subsurface ocean, such as Europa and Titan. Europa is closer to us than Pluto, and it's likely that there are wide, warm oceans hidden beneath its frost-covered surface, and some scientists believe that Pluto may have been like Europa, who found a huge basin on Pluto's solid nitrogen and carbon monoxide ice surface that would never have formed without oceans beneath it.
The discovery has bothered astronomers for a long time because they have no way of explaining how Pluto formed oceans at such temperatures, but new theories suggest that Pluto may have a layer of insulated gas that guarantees it shelters a vast, independent sea. If this is true, not only could there be alien beings on Pluto, but we could even send humans to Pluto in the future.
Thankfully, before the development of our technology allowed us to reach Pluto, we most likely completed our exploration of Europa. Europa is environmentally similar to Pluto, so that we can gain useful knowledge about Pluto by exploring Europa. Pluto is very far from the Sun, which would largely prevent the evolution of life. Also because of the distance, we know very little about it. Is Pluto a desolate, dark wasteland, or a secret paradise for aquatic aliens? Until science and technology give us a definitive answer, we can at least assume that the latter scenario is possible. This is the hidden side of Pluto. What do you think about that? Are we ignoring something?
Europa /j ro p/, also known as Jupiter II, is the smallest of the four Galilean moons orbiting Jupiter and the sixth-largest of Jupiter's 80 known moons. It is also the sixth largest moon in the solar system. Europa was discovered in 1610 by Galileo Galilei,[1] and named after Europa, the Phoenician mother of King Minos of Crete and lover of Zeus (Greek equivalent to the Roman god Jupiter).
Slightly smaller than the Moon, Europa is composed mainly of silicate rocks, has a water-ice shell,[14] and may have an iron-nickel core. Its atmosphere is very thin and composed mainly of oxygen. It has cracks and stripes on its surface, but there are relatively few craters. In addition to observations made with telescopes on Earth, Europa has been examined by a series of space probe flybys, the first of which took place in the early 1970s.
Europa is one of the smoothest surfaces of any known solid object in the solar system. This structure leads us to speculate that there may be an ocean beneath its surface, and that the existence of the ocean makes it possible to be the site of extraterrestrial life. [15] Computational models show that the heat generated by tidal bending is able to keep the ocean liquid and push ice blocks to transfer chemicals from the ocean surface to the bottom in a manner similar to plate movement. [16] [17] Some of Europa's surface may have been caused by sea salt covering from the bottom of the ocean, suggesting that its ocean surface interacts with the bottom.
This way of exchanging substances is important for determining whether Europa is habitable. [18] In addition, the Water Vapor Plume observed by The Hubble Space Telescope is similar to that observed on Saturn's moon Enceladus, which is thought to be caused by the eruption of low-temperature geysers. [19] In May 2018, astronomers provided supporting evidence of water vapor plume activity on Europa based on a recent analysis of data from the Galileo space probe orbiting Jupiter from 1995 to 2003. This plume activity could help researchers look for life inside its ocean without logging into Europa.
