    Mystery of oxygen on Mars ।।Which has robbed scientists of sleep
    March 02, 2021

    We are constantly taking in oxygen and releasing carbon dioxide. This is how we live. If there is no oxygen in this world for a moment, then I will kill you all in a few moments. This is how we live on earth from the past. But in the present day, for some work done by human beings, this world is slowly going to destruction. So scientists have already begun to search for a new world. And from that point of view, Mars is currently the best planet to live near scientists. Every year big space organizations like NASA, ESA, ISRO do many missions. And the famous SpaceX company is very interested in this.
    [​IMG]
    But from what scientists have learned so far through the Mars mission, scientists think that the past may have been life on this planet, but it is no longer there. Many of the pictures we have received so far are mysterious in themselves. Mars has been found to have Earth-like ice again. And like the Earth, Mars has discovered oxygen, which in itself is quite mysterious and which is a big problem for human civilization to settle in Mars.

    If we look at the gas present on Mars, we will see =>

    ●Carbon dioxide: 95.32 percent.
    ●Nitrogen: 2.7 percent.
    ●Argon: 1.6 percent.
    ●Oxygen: 0.13 percent.
    ●Carbon monoxide: 0.08 percent.

    On the other hand, if we look at the gas in the earth =>
    ○ 78.09% nitrogen,
    ○ 20.95% oxygen,
    ○ 0.93% argon,
    ○ 0.04% carbon dioxide,
    and small amounts of other gases.
    [​IMG]
    Then we will see that there are many differences between the gases of these two planets.
    But scientists have found that the difference between these gases can be seen when Mars is in summer and winter.
    When winter comes from winter to summer, it is seen that oxygen is like 60%. Again during the spring the amount of methane gas increases a lot. According to NASA scientists, it does not increase or decrease at the same rate every year, it increases differently every year.

    [​IMG]
    However, this change is also happening in our world but it is very small. Regarding the change in the gas of Mars, the scientists said that due to some of the reactions specified in Mars, the gas shots change, but the scientists have not yet found out why the reactions are like? How are reactions shot? This is a huge mystery to scientists. And as long as scientists do not unravel this mystery, there will be no human settlement on Mars.

    Emission Nebula Sh2-114
    Sh2-114 is a complex and unusual HII emission nebula. Its complex and wispy structure is likely the result of winds from hot, massive stars interacting with the magnetic fields in the interstellar medium. But very little is known about it.
