In finding planets and having a list, i am ignorant if Fermi Bubble X-rays are factored into goldilocks concepts. Abundant and unusual by-products sound as if remote sensing factors out galactic location in proximity to Fermi Bubbles. Sputnik as a start of 60 years of remote sensing is good History. History cures technology

June 24, 2026 at 3:45 amt’s hard to say that there surely is life in planet far away from earth. We cannot take samples, and if many light years away, there is that time difference too. If planet which we are studying is say thousand light years away, it takes thousand years to light to travel from there to reach us.
June 24, 2026 at 3:42 amI don’t believe it is right to strike off gaseous planets while not having a fundamental definition for life. However, resources and time can be better spent on habitable planets rather than gaseous and inhabitable ones.
June 24, 2026 at 3:40 amIt is quite possible that a thing as complex as life has some qualities that could yet surprise us and redefine our understanding. What we try to consider is life similar to the one on Earth and even with the NASA’s definition there could be different types of systems and organisms, based on different chemistry, or adhering to separate set of rules. Viruses are an interesting example of microbes that are considered to be not-living, yet they are certainly not the same as non-living matter, such as rock
