Data has been flooding in from the nation’s latest space telescope, one with a 30-meter-diameter mirror (the Hubble’s, for comparison, was 2.4 meters). The initial searches for signs of life on exoplanets by 2020s telescopes found so many tantalizing hints. The new telescope, with thousands of times the capability, has searched hundreds of the nearest Earth-size exoplanets and found something astonishing: A large fraction show unusual chemistry in their atmospheres.
We are working hard to understand if any of the unusual chemistry can be attributed to gases produced by life. If geophysical or other contributions can be ruled out, we might establish that our galaxy is teeming with life, or at least microbial life.
If we instead hit a dead end with ambiguous chemical signals, we’ll need to go to the next step. Thanks to telomere gene therapy that has extended my life, I am willing and able to direct an even more capable space telescope, but that isn’t good enough. We will have to leave it to the next generations to figure out how to send the first interstellar space probes to actually travel up to tens of light years away to visit the other Earths.
