ZONAUTARA.com – Living things need air, especially humans. Likewise with animals and plants. In his exploration in advance Earthhumans are constantly looking for water sources that can guarantee supply at all times.
As the Earth’s population continues to grow, humans begin to explore the possibility of living on Earth planet other than Earth. Of course, one of the main requirements for the planet to be inhabited by humans, is a source of water.
Scientists also believe, if there really are other creatures that live other than on Earth, of course they also need it air. Even if humans are ultimately alone in this universe, knowing the location of water other than on Earth is important if humans decide to venture far from planet Earth.
Fortunately, today with the help of modern science, astronomers can find water other than on Earth. Advances in modern science coupled with advanced technology allow astronomers to find water across great distances even under obstacles as diverse as dense clouds and miles of ice sheet.
Reported from BigThinkHere are 6 locations in the Solar System that are believed to have water sources.
Mars
Despite the idea that Mars is home to large canals filled with enough water to sustain the lush vegetation has been disputed since the 1920s, but Mars is believed to have had a fair amount of water in Lake Superior.
Most of the water on Mars freezes in its polar ice caps, and a small amount can be found in the Martian atmosphere.
Air liquid forms exist only in small lakes under glaciers at the Martian poles. Identified via radar, the lake is 1.5 kilometers beneath the ice sheet and is thought to remain liquid due to the anti-freezing properties of some minerals that are present in soil on Mars.
Europe
One of Jupiter’s moons in Galilee, Europa, is famous for its dense icy surface and the ocean that stretches beneath its surface.
The ice crust on the planet is estimated to be several thousand meters to 30 kilometers thick. The ocean below is estimated to be 100 kilometers deep, with some of it probably containing a mixture of liquid near the top and most of it liquid at the bottom.
If true, this means that Europa has more air than in all the oceans on Earth, and almost three times their volume.
This vast ocean, which remains warm due to Europa’s volcanic core and the effects of tidal forces on Jupiter’s moons, is considered a possible habitat for extraterrestrial life. The vents, similar to hydrothermal vents on Earth, can provide energy and conditions for life in environments that are never even exposed to sunlight.
Ganymede
Ganymede is another Galilean moon of Jupiter and the ninth largest object in the solar system — larger than Mercury and Pluto. This moon is known to be the only moon in the solar system with a magnetic field, which helps show that there is a large ocean beneath its icy surface.
By observing the movement of Ganymede’s magnetic field, caused in part by its interaction with Jupiter, the astronomers noted small changes that indicated the presence of a large saltwater ocean.
This ocean is estimated to be under a layer of ice as thick as 150 kilometers and a depth of 100 kilometers. Like Europa, Ganymede can also have more air in it of all the oceans that are on Earth.
More recent observations have confirmed the presence of water vapor in Ganymede’s thin atmosphere, possibly caused by the sublimation of water ice on the surface.
Ice giants on Uranus and Neptune
The planets Uranus and Neptune are known as “ice giants” because they are composed of elements heavier than hydrogen and helium combined with large amounts of water, ammonia, and methane ice.
Unlike the gas giants Jupiter and Saturn, which rely on gas to provide 85 percent of their mass, the ice giants on these two planets are believed to have supercritical oceans of water — that is, water at temperatures and pressures above the so-called tipping point, where both liquids and gases exist. become indistinguishable. This supercritical water makes up two-thirds of the total mass on these two planets.
Ice giants on both Uranus and Neptune are thought to be common around other stars. How exactly they formed is still unknown, but future missions to find out are under discussion.
Titan
Saturn’s largest and most interesting moon, Titan, is a strange place. The solar system’s second-largest moon (after Ganymede), Titan is characterized by an atmosphere of nitrogen and so much liquid methane that there is a “methane cycle” no different from Earth’s water cycle — complete with rain, lakes, rivers, and oceans at cold temperatures. -179°C (−290°F).
Water ice is thought to be beneath Titan’s rocky surface, and liquid water mixed with ammonia to prevent it from freezing is thought to be beneath Titan’s surface. This conjecture was discovered by the Cassini probe, which examines tidal forces on the moon.
Astrophysicists believe that the force is strong enough to engage the subsurface ocean, which is likely composed of water.
Conclusions about the source of Water
Air is something that is very vital for the life of living things. Finding water sources for the supply of life in the future is something that must be done from now on.
The human population continues to grow and Earth getting crowded. One day humans and other living things will experience a water crisis. The water source must be accessible even if it is elsewhere in the Solar System.
