βThe OSIRIS-REx team found a rough surface littered with boulders instead of the smooth, sandy beach they had expected based on observations from Earth- and space-based telescopes.β
But these same telescopes can accurately observe exoplanets and solar systems millions of light years from Earth. π
Of the thousands of exoplanets discovered so far, less than a dozen have been found using telescopes. The rest have relied upon other more indirect methods, and are typically hundreds or thousands of light years away, not millions.
