The Search For Extraterrestrial Life, UFOS, And Our Future

Earlier this year, scientists spotted the building blocks of RNA at the center of the Milky Way. RNA, or ribonucleic acid, a molecule similar to DNA and it is present in all living cells. The team of researchers discovered the building blocks of RNA in a molecular cloud in our galaxy. Such building blocks have also been discovered on asteroids. Most notably, Japanese researchers discovered more than 20 amino acids on the space rock Ryugu, which is more than 200 million miles (320 million kilometers) from Earth. Scientists made the detection by studying samples retrieved from the near-Earth asteroid by the Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 spacecraft, which landed on Ryugu in 2018. According to Kensei Kobayashi, a professor emeritus of astrobiology at Yokohama National University, "Proving amino acids exist in the subsurface of asteroids increases the likelihood that the compounds arrived on Earth from space. This means that amino acids could likely be found on other planets and natural satellites – a clue that "life could have been born in more places in the Universe than previously thought," Building Blocks of Life Were Found on an Asteroid in Space For The Very First Time: ScienceAlert Victoria Meadows, Principal Investigator for NASA's Virtual Planetary Laboratory at the University of Washington has noted that life forms can produce detectable indicators, including the presence of substantial amounts of oxygen, smaller amounts of methane, and a variety of other chemicals. She believes that "upcoming telescopes in space and on the ground will have the capability to observe the atmospheres of Earth-sized planets orbiting nearby cool stars, so it's important to understand how best to recognize signs of habitability and life on these planets," Meadows said, "These computer models will help us determine whether an observed planet is more or less likely to support life."
