 NASA's lead study suggests we may not recognize extraterrestrial life when we see it or vice versa. With all the hype about the heralding of the modern space frontier, we are questioning many different perspectives and top of the list is the age-old subject is, of course, alien life or more specifically, intelligent life that is not human. Some of NASA's leading space boffins have spoken out about the possibility alien life on other planets looks nothing like that on Earth. Exploring the concept in a series of papers published in the scientific journal Astrobiology, NASA experts in astronomy, biology and geology re-evaluated the markers indicative of alien life. Until now, scientists have primarily scanned the stars for atmospheric signs of oxygen, a key element in the development of life here on Earth. But what if alien life forms thrive in low oxygen atmospheres? Wait to hear this. We're moving from theorizing about life elsewhere in our galaxy to a robust science that will eventually give us the answer we seek to that profound question. Are we alone? The assessment comes as a new generation of space and ground-based telescopes are in development. NASA's James Webb Space Telescope will characterize the atmosphere of some of the first small rocky planets that it observes. Other observatories such as the giant Magellan telescope and the extremely large telescope both in Chile, by the way, are planning to carry sophisticated instruments capable of detecting the first biosignatures on far away worlds. Through their work, scientists aim to identify the instruments needed to detect potential life for future missions. The detection of atmospheric signatures of a few potentially habitable planets may come sooner than we could ever have anticipated, although whether the planets are truly habitable or have life will require humans to actually go there. It makes you wonder, does it not? What's the point of searching for places we currently don't have the technical ability to reach? Wouldn't it make more sense to develop warp drive or light speed or space jumps? Whatever you want to call it. Doesn't it make sense to have the means of travel first? Well, what if they do? It really is no major secret that the government has been plowing trillions into these types of projects for decades. For all we know, they already have an arc ready to evacuate the Earth and go to these far away places. We always wonder about the whole Orion correlation concept. Could this type of evacuation have happened before? The last cataclysm and the Orion markers are the arrow to where they went. Since we won't be able to visit distant planets and collect samples anytime soon, so they say. The light that a telescope observes will be all we have in the search for life outside our solar system. Telescopes can examine the light reflecting off a distant world to show us the kinds of gases in the atmosphere and their seasonal variations as well as colors like green that could indicate life. These kinds of biosignatures can all be seen on our fertile Earth from space, but the new worlds we examine will differ significantly. For example, many of the promising planets we have found are around cooler stars, which emit light in the infrared spectrum rather than our sun's high emission of visible light. We have to be open to the possibility that life may arise in many contexts in a galaxy with so many diverse worlds, perhaps with purple-colored life instead of the familiar green-dominated lifeforms of our own planet. Rather than measuring a single characteristic, scientists argue that we should be looking at a suite of traits. A planet must show itself capable of supporting life through its features and those of its parent star. We won't have a yes or no answer to finding life elsewhere. What we will have is a high level of probability that a planet appears alive for reasons that can only be explained by the presence of life. Is it really that important to leave the Earth in the future? Will our civilization even survive long enough to do so? And is the work simply the foundation stones to future space travel? Consider the age of the universe, the age of the solar system, and indeed the age of the Earth. Us humans have popped up out of nowhere in the grand scheme of things, and there was a long period in time where humans or indeed aliens and possibly any form of anything whatsoever never existed. If aliens or the gods created us, who created them? And before the creation of the creators of the gods, who created that civilization? It goes all the way back to a single starting point of everything, right? But how long did the period where there was nothing stay dormant? And how did it become dormant? If there was a period of nonexistence of anything, then surely there must have been something even before there was nothing. And before that, what was there and what is the universe and what exactly surrounds the vast vacuum? What's going on? Anyway guys, what do you consider the truth to be? It's below and as always, thank you for watching.
