{"product_id":"2940011939266","title":"Be A Stargazer: A Guide to Astronomy","description":"All sciences are making an advance, but Astronomy is moving at high\u003cbr\u003espeed. Since the principles of this science were settled by Copernicus,\u003cbr\u003efour hundred years ago, it has never had to beat a retreat. It is\u003cbr\u003erewritten not to correct material errors, but to incorporate new\u003cbr\u003ediscoveries.\u003cbr\u003e\u003cbr\u003eAt one time, Astronomy studied mostly tides, seasons, and telescopic\u003cbr\u003easpects of the planets; now these are only primary matters. Once it\u003cbr\u003econsidered stars as mere fixed points of light; now it studies them as\u003cbr\u003esuns, determines their age, size, color, movements, chemical\u003cbr\u003econstitution, and the revolution of their planets. \u003cbr\u003e\u003cbr\u003eOnce it considered space as empty; now it knows that every cubic inch of it quivers with greater intensity of force than that which is visible in Niagara. Every inch of surface that can be conceived of between suns is more wavetossed\u003cbr\u003ethan the ocean in a storm.\u003cbr\u003e\u003cbr\u003eThe invention of the telescope constituted one era in Astronomy; its\u003cbr\u003eperfection in our day, another; and the discoveries of the spectroscope\u003cbr\u003ea third—no less important than either of the others. New discoveries\u003cbr\u003eare made every day with the advancement of telescopes.","brand":"M\u0026M Pubs","offers":[{"title":"Default Title","offer_id":47163114193136,"sku":"2940011939266","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940011939266_p0.jpg?v=1763551761","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940011939266","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
