Europa: Under the icy shell of a filled coconut is the sound or the pulse of life?

- A look at : Harshal Pushkarna

- 'Aap aandar se kuch aur, bahar se kuch aur nazar ate hai!' Why does this line fit Jupiter's moon Europa?

- NASA has discovered an ocean beneath Europa's icy surface. Now it's time to explore the potential ecosystem in that ocean, the moment of which is in the near future.

- If the heat from Europa's womb was transferred to the ocean through underground fractures, a future probe would have to be sent to find out if life had been introduced there.

There is communication of life in all three 'lokas' of our divine Vasundhara, water, earth and sky. Even in the deep depths of the ocean, where light cannot reach, sponges with a special body structure live. The solid land jutting out from the ocean throbs with countless species of life, while the skies are alive with birds, insects and microbes. In short, from the abyss to the sky about 21 kilometers high in the fabled chabutara, different organisms live in different spheres.

Twenty one kilometers! What a paltry figure in the context of infinite space! Doesn't it sound a bit strange that the alleged creator who 'constructed' the universe created billions of celestial bodies and breathed life into a belt only twenty one kilometers thick on the body called Earth?

The question is not of science, but of simple logic. This is why before science took off in AD. In 400 BC (about 2,400 years before today), the ancient Greek philosopher Metrodorus said, 'To assume that there is life on Earth alone in space is like saying that a single grain of wheat sprouts on only one plant out of millions in a vast field of wheat'.

Many plausible logics are not dated or time bound. The logical point raised by Metrodorus 2,400 years ago is of that type, therefore still eternal. 'Are we earthlings alone in the entire universe?/ Chii hui Charnahid? The question has been evergreen for the last fifty years as if it had come with an immortal belt. Astronomers have been blown away by it. He has repeatedly knocked on the door of nearest neighbors like Moon and Mars and said 'Koi Hai?' But still no reply. No idea when to meet? However, efforts have not been abandoned.

When water is found on the moon and life is found on Mars, then, but in the meantime, know it as a fresh verse here. The news is from September 29, 2022 and comes from the gas giant Jupiter's moon Europa. The news broadcaster is named after the 'Verh/Juno' spacecraft which was launched by the US space agency NASA on August 5, 2011 from Earth to Jupiter. Juno, a scientific probe of the gas giant Jupiter and its four main moons (namely: Io, Ganymede, Callisto and Europa), passed just 400 kilometers above the surface of Europa on September 29. The close-up images the spacecraft's powerful camera sent to NASA of Europa's icy surface were unprecedented at the time. Because the clear face of Europa as seen in it has never been seen before.

Is. In 1610, Galileo Galilei of Italy discovered Jupiter and its four moons with a self-made telescope. For three and a half hundred years after this discovery, the astronomical world remained in the dark about the constitution of the five distant celestial bodies. Finally the light of knowledge was spread by NASA's 'Pioneer' and 'Voyager' spacecrafts which visited Jupiter in the 1970s. Both the spacecraft's cameras and vibration sensors have extracted the geodesics of all four moons besides Jupiter, so based on that NASA pundits have obtained the bio-data of each one sitting here. The most interesting object of the five was Europa, as Voyager's instruments discovered a sea of ​​salt water swirling beneath its icy surface. It was a matter of great excitement to have water on a body other than Earth in the solar system and that too in the form of an ocean. Because if there is water on Europa, it is possible that life has flourished in it. After all, water is life!

The expression water = life used in daily practice is somewhat understandable from the point of view of science. Water is the most essential ingredient for the birth of life. Humans, non-human beings and plants have evolved and evolved on Earth because their cells contain about 80 percent water. That means the cell is mostly in liquid form. Biological chemicals, from proteins to gastric juices, cannot exist without liquid form. If their form is not liquid, it will not reach some or all parts of the body to perform biological action.

Another point: Without a fluid called electrolyte made up of chemicals like sodium, potassium, calcium, magnesium, etc., it is not possible for the brain to generate electrical signals. Such signals are key to everything from thinking to moving the arms and legs.

Third and most important: If the cell is in a completely dry, solid form instead of 'watery', it will not divide at all. No division, no creation of new cells' and if no new cells are made, biological development stops.

This is the scientific essence of water = life formula! This saying applies not only to the earth, but also to every planet-satellite in the universe. Hence, life on a celestial body can sprout only when there is water. Astronomers have discovered a number of planets outside the solar system, but most are not watery like Earth. Rather, they are like dried topra. Jupiter's moon Europa, on the other hand, is a coconut with salty water inside its icy shell.

As far as is known about Europa, its inner core is composed mainly of iron and nickel, overlain by a layer of soil and rock several kilometers thick. Voyager's sensors found that there was a maximum depth of 160 kilometers above this layer. In space, the sphere of Europa is arranged at a distance of 78 million kilometers from the Sun, so its surface is not particularly influenced by solar rays. Due to this, the average surface temperature of Europa is 160 degrees Celsius below zero. A large part of Europa's sea surface has turned into thick ice in such an ice cold winter. The ice crust in our North Pole region is constantly floating (like cream on milk) on the Arctic Ocean. The same is true of Europa. The difference is that there is a thick layer of ice surrounding the entire sphere. Hence Europa's white, icy surface sparkles like a glittering marble floor.

As reported by Voyager in the past and more recently by Juno, Europa's surface is marble-like, but not smooth. Rather, it has long-wide joints in many places. The joints are formed when subterranean sea water penetrates the solid surface ice and then turns into ice under temperatures of minus 160 degrees Celsius.

If the above paragraph has been read correctly, then one question keeps coming to mind that, where did the sea water get such strength to break the crumbling crust of ice?

For the answer, one has to dive deeper into Europa's oceans. (All pearls of knowledge are found in the depths.) Europa's sphere is positioned between the giant Jupiter and the Ganymede moon. On the one hand it is treated by the enormous gravity of Jupiter, on the other hand by Ganymede! Like a game of tug-of-war, the inner part of Europa is never stable because of that mutual pull. There is constant shaking, which results in the subterranean sea being strongly agitated, causing tides hundreds of meters high. The pressure of the waves is so great that it breaks the floating icy crust. As soon as there is a breach in the surface, a stream of water comes out through it like a fountain. (See, drawing). The water that penetrates the ice sheet turns into solid ice instantly.

Let us now turn the focus of the discussion back to the potential ecosystems of Europa's oceans. Jupiter and Ganymede's gravitational pulls burn Europa's inner core like a furnace. Scientists believe that heat from the core's rifting is transferred to seawater through geological fractures. This belief is not unfounded; It has a solid foundation. Geological faults are located at the bottom of the Earth's deep oceans. The lava bubbling up in the Earth's womb flows through the cracks into the ocean and warms the surrounding water. Due to the warm weather, bacteria, single-celled algae, various microbes, multi-cellular organisms, cyanobacteria, cyanobacteria and crustaceans have flourished in that area. Could primal life have similarly collapsed under Europa's ocean floor? The answer can only be found when a spacecraft peers into Europa's icy crust.

Of course, good news! Exactly one year from today; After eleven months, NASA's 'Europa Clipper' spacecraft is set to leave for Europa. It will reach its destination after a five-and-a-half-year space journey, followed by a four-year orbit around Europa. During each orbit it is to 'sweep' Europa's subterranean sea with its complex apparatus. Especially measuring the temperature of the deep sea water, which is suitable for the development of the ecosystem, understanding that 'Are we earthlings alone in the entire universe? The future is not too far back. Because after 'Europa Clipper' NASA is going to send one more craft called 'Europa Lander'. The mission of the craft that has landed on Europa's soil is to knock on the icy door 'Anyone in?' If Saad Jilayo is fine, otherwise go find another door in the universe!?
