Alas, later evidence suggested his conclusions were incorrect, but I learned a great deal about the subject, as well as about the scientific method, by studying what this impressive astronomer had accomplished.Finally in the middle 1990s, astronomers found strong evidence of planets around other stars.
NASA's Kepler mission used this technique to identify hundreds of stars that may have planets. With all those other stars, why haven't scientists studied other solar systems, at least enough to know how many are in our galaxy? And the stars, along with any planets under their control, are so far away that picking out a faint planet near a distant star is like spotting a mosquito next to a brilliant searchlight miles away.Marc Rayman at age 14 meets astronomer Peter
Many of the 4,000+ planets so far discovered in distant star systems in the Milky Way are "water worlds" according to new research. (Image from Sky and Telescope, Aug. 1971. Our solar system is one of over 500 known solar systems in the entire Milky Way galaxy. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone. Given how many they have found in our own neighborhood of the Milky Way galaxy, scientists estimate that there may be tens of billions of solar systems in our galaxy, perhaps even as many as 100 billion.
