Life on K2-18b?

Important Gases Found on Exoplanet.

As long as humans have looked up at the sky, we have wondered what's out there. Are we the only life in the entirety of the universe? Is our planet unique in supporting life in the cosmos?

We have had tantalising glimpses that Mars once supported life, and life might still exist. We have glimpses that Venus may contain life in its upper atmosphere. The ice moons of Europa, Enceladus, and others may contain life in vast oceans under their ice sheets.

People claim to have seen UAPS/UFOS and even engaged with extraterrestrials. The US military has released footage of what they say are craft that can outperform anything we have. Whether these extraterrestrial vehicles are alien is open to question. If these vehicles are Russian, Chinese, Iranian, or North Korean, the West is in big trouble. The government seems to be drip-drip feeding us stuff they have known for years. More information will no doubt be coming out in the future.

Many think that there would be mass panic, the end of faith, a reexamination of everything our society stands for. And while that is a valid point of view, some folk wouldn't be surprised if there were life elsewhere. As a Christian, if God created life elsewhere, it wouldn't surprise me; it would vindicate something I've always felt. How others handle it is a matter for them.

The discovery of exoplanets in recent years has proved there are other worlds revolving around their stars (suns). One planet in particular that has been observed by the James Webb telescope is K2-18b. K2-18b is located 124 light years from Earth. It is found in the constellation Leo and is 8.6 times larger than our planet. Its diameter is 2.6 times larger than our planet's.

The planet sits in the so-called habitable zone, where our world sits. Third rock from the sun, not too hot, not too cold, hence the Goldilocks zone. So the planet is a twin of Earth. On a larger planet, the gravity would be stronger on K2-18b. I can see why the Goldilocks theory makes sense, however, I have spoken about Mars and other worlds in our solar system. Those worlds are not in the Goldilocks zone, and yet it is suspected that there was life or is life on those worlds. So I think to dismiss worlds that are not in the Goldilocks zone and say life doesn't exist there is too simplistic. We have shown that on Earth, life finds a way in a myriad of environments. So why should it be different on other planets?

Scientists have found on K2-18b gases that could indicate life or a biological process. Scientists, however, remain cautious, understandable really. Very few scientists are prepared to put their heads above the parapet and say this is life. Saying it is a process that could indicate life is a get out clause for them. Just in case, it isn't life, as some chemical reactions can often imitate life. Avi Loeb remains one scientist who isn't afraid to put His views out there. His view that Oumuamua was an alien craft is not accepted by many of his contemporaries. But this Israeli scientist is prepared to push the boundaries of science, and that can only be a good thing.

Using the James Webb telescope, scientists have detected traces of two gases. One is known as DMS, and the other is DMDS. These gases on Earth indicate life from algae to much more complex forms of life. This could indicate K2-18b is teeming with life.

Finally, an eminent professor from Cambridge University's Institute of Astrobiology Nikku Madhusudhan, said, "We have entered the era of observational biology".
