While we still don't have a precise estimate of the number of habitable planets in our galaxy, advances in astronomy have allowed us to detect and study exoplanets (planets outside of our solar system) and infer their potential habitability. This has given us a better understanding of the number of potential habitable planets in our galaxy. The other factors in the modified Drake equation are much harder to estimate, as they involve complex and uncertain variables such as the likelihood of life arising on a habitable planet and the probability of civilizations developing on those planets.
