Brahe finds cometIn 1590, Tycho Brahe discovered a comet in the constellation Pisces, the Fish. He had previously shown, by measurements of parallax for a comet he observed in 1577, that comets were further away than the Moon. This contradicted the teachings of Aristotle (who held comets to be a phenomenon within the atmosphere), and Brahe was the first to prove the truth. |
