But HARPS is already sensitive enough to spot planets that are 100,000 times smaller than their parent star. Refinements both in HARPS itself and in the next generation of planet-hunting telescopes should make them able to spot smaller and smaller stellar wobbles. Those little...
When Burke K. Zimmerman ’58 was studying iron meteorites to determine the date of origin of the solar system as a research assistant at the Smithsonian Astrophysical Observatory (SAO), he said he never thought others would be using stopwatches to compute the orbit of Sputnik, the Soviet satellite sent into orbit the fall of his senior year...
...Zimmerman and his classmates were just getting back in the rhythm of their final year at the College, the Soviet Union launched the first man-made satellite, which would orbit the Earth for the next three months...
