A Stanford scientist says a new planetary model may explain why we have not found aliens yet, arguing that most small rocky worlds simply cannot hold onto the atmospheres needed for life, and that Earth might be 'one of the first' habitable planets in our galaxy. The software tool, developed at Stanford University in California and unveiled this week, is designed to help astronomers decide which distant exoplanets to study with powerful telescopes.
Over the past three decades, astronomers have confirmed thousands of exoplanets orbiting stars beyond the Sun, with estimates of billions more scattered through the Milky Way. There is now, quite literally, too much to look at. As next‑generation observatories queue up targets, researchers are scrambling for ways to triage that cosmic backlog and work out where to spend scarce observing time.
