Seeing planets like never before
Until the end of the 20th century, ours was the only planetary system known. We now know of more planets outside our solar system than within it. Astronomers have now located more than 1,000 planets orbiting stars other than our own, and the latest observations are starting to reveal what these planets are like. The American Museum of Natural History-led Project 1640 is at the forefront of this research. The project’s advanced telescope instrumentation can spot chemical fingerprints that will help characterize how exoplanets form, evolve, and differ from familiar planets closer to home.
