Astronomers are closer to identifying habitable worlds.
NASA just passed a remarkable threshold with more than 6,000 confirmed exoplanets, a tally that reshapes how we view our place in the universe. Each discovery adds detail to a sprawling cosmic map, where worlds range from gas giants hugging their stars to rocky planets orbiting in temperate zones. The milestone is not just about numbers—it is about narrowing down the rare conditions that make life possible. With missions like TESS and Webb already rewriting the playbook, the next chapter feels closer than ever. The search for Earth 2.0 has shifted from dream to tangible scientific pursuit.
