Life on Alien Planet? | James Webb Telescope Discoveries | Dhruv Rathee

       it's all an illusion created by the wavelength. For example, why do we see trees, plants, and leaves as green in color? Because they contain chlorophyll. Chlorophyll is unique because it absorbs red and blue color wavelengths, and the wavelength which it cannot absorb, that's the green color, is what we can see. Similarly, the water in oceans looks blue to us. Because it is water's property to absorb the other wavelengths of red, yellow, and orange, and since it cannot absorb the blue wavelength present in light, we see it as blue in color. The same logic can be applied in reverse as well. If we pass light through a leaf, In the light on the other side the red and blue wavelengths would be blocked. If we measure it through a spectrograph and create a chart, We will be able to see a certain pattern with which we can draw the conclusion that if the same pattern is repeated somewhere else, it is most likely that the second thing is similar to a leaf. Or may even be a leaf itself. The light from the WASP - 96B, was captured by this telescope,

a graph was prepared on the spectrograph, and the blocked wavelengths of light were analyzed. Scientists know the exact ratio of blockage of wavelength to know which molecule the light had to pass through. That's why the graph that you can see here, has the wavelengths of light on the X axis, And the amount of light blocked is on the Y axis. The scientists knew that if a certain amount of light is blocked at a wavelength, it was evidence of the presence of H2O. The same thing happened here. And so we can conclude that there's water on this exoplanet. If you are happy knowing that the presence of water on this planet may signify the presence of life on it, that we mightfindaliensthere, don't be so happy.Because this planet is not habitable. Scientists have discovered other facts about the planet, First of all, the closeness of the planet to its star, and the size of the planet, with those parameters, they have estimated that the temperature on that planet is more than 530°C. So the chances of finding aliens on this planet are next to none. But over the next few months,

the James Webb Spcae Telescopewill analyze another planet, it will be pointed towards a new planet,

to take pictures of that planet, which is said to be one of the most potentially habitable planets. Friends, if you are interested in the field of space, I would like to recommend 2 book summaries on KUKU FM,
