And although faithfully recorded, Galileo did not recognize he had found another planet. \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p2\" data-mce-fragment=\"1\"\u003e\u003cspan class=\"Apple-converted-space\" data-mce-fragment=\"1\"\u003e\u003cspan\u003eSo, who should receive recognition for the discovery?
