NASA James Webb Scientist Reveal How TRAPPIST 1 Is Home to Aliens

Trappist - NASA James Webb Scientist Reveal How TRAPPIST - 1 Is Home to Aliens: Are humans the only species in the universe? Or are there other intelligent beings looking up into the sky from different worlds and asking the same question? And are there more advanced civilizations? What lies beyond what we can see? These questions have inspired countless films and TV shows, books, podcasts, artwork, and conspiracy theories, but the question of whether or not we are truly alone in the universe remains unanswered. However, new technology may be bringing us closer to answers than ever before.
Stay glued to this video as we discuss how we may be itching closer to definite answers about extraterrestrial life, or more popularly known, alien life. Be sure to like, subscribe, and leave a comment.
Many people believe that humans are the only civilized life forms in the universe. This notion is reasonable since there has not been any solid evidence that proves otherwise. But things are about to change. According to a NASA expert, scientists will be able to determine whether a group of nearby exoplanets is habitable or not by studying their potential atmospheres.
According to NASA astrobiologist Shawn Domagal-Goldman, the question of whether the TRAPPIST-1 exoplanets have atmospheres is "the most important" scientific investigation that anyone involved in the search for alien life will be doing for potentially a decade. Despite decades of searching for signals and an ever-expanding list of exoplanets (planets orbiting other stars), scientists have never discovered evidence of life anywhere other than Earth. Imagine scientists finally proving that aliens actually exist! This will have significant implications for science, philosophy, and religion.
The TRAPPIST-1-star system consists of at least seven exoplanets orbiting a dwarf star roughly 40 light-years away from Earth that is thought to be the best candidate for potentially habitable worlds—and possibly even life. In essence, these planets resemble Earth and appear to be habitable. While early research has shown that the planets are stony and perhaps temperate, it has been hard to determine with previous technology whether or not they have atmospheres.
That was before NASA's most potent space telescope, the James Webb Space Telescope (JWST), was put into orbit in December. This new technology is what is going to help scientists explore TRAPPIST-1. Webb has already created the most in-depth infrared image of the universe in history by gazing into the cosmos using a massive array of mirrors to help it gather as much light as possible.
It has also had its sights set on TRAPPIST-1 as a priority for several weeks. The telescope will be looking for any sign of an atmosphere surrounding the planets. Domagal-Goldman mentioned that just like him, many others are wondering if these planets have atmospheres. He reiterated that atmospheres are crucial for the type of habitation. He went on to say that the moon gets just as much energy from the sun as the Earth does, but it doesn't hold on to its atmosphere, so it doesn't have any oceans and it doesn't have any global biosphere.
The TRAPPIST worlds are big enough to maintain their atmospheres because more gravity results from the increased mass. The question is whether TRAPPIST-1, their neighboring star, has been violent enough to periodically blast these atmospheres away due to bursts of high-energy radiation. To determine whether these worlds are habitable, it is necessary to determine whether they have atmospheres. Luckily, that's also the most basic thing Webb can notice, explained Domagal-Goldman.
If Webb is successful in identifying atmospheres on any of the TRAPPIST planets, the next task will be to investigate the atmosphere's components. This will shift the focus of research from the capacity of planets to support life to whether they actually support life.
This is where it gets complex in the sense that, analyzing if these planets support life involves extensive measurements of the planets via a technique known as transit spectroscopy.
