A team of scientists are preparing to use NASA's upcoming Habitable Worlds Observatory to answer one of the most profound questions of all time: How does life begin? Rather than searching for individual signs of life, the team plan to study patterns across dozens of exoplanets to test competing theories about the origins of life; from scenarios where life is so rare we might be alone within 33 light-years, to theories predicting that life emerges wherever basic conditions exist. This approach could transform perhaps our oldest question into testable science, potentially revealing whether our biosphere is an accident or part of a universe teeming with life.

Rather than searching for life in laboratories or on Mars, researchers led by Sukrit Ranjan from the University of Arizona propose using the HWO to examine patterns of life across multiple exoplanets. Their approach is really quite simple: different theories about how life begins make different predictions about where and how often life should appear. They propose that by observing enough planets, the theories can be tested against real data.

    Countdown to Trump administration forcing this awesome telescope to be axed…

    We don’t get to have nice things anymore, just more tax cuts for the wealthy. :(
