{"product_id":"9781139097383","title":"Deep-Sky Companions: The Secret Deep","description":"In this fresh list, Stephen James O'Meara presents 109 new objects for stargazers to observe. The Secret Deep list contains many exceptional objects, including a planetary nebula whose last thermal pulse produced a circumstellar shell similar to the one expected in the final days of our Sun's life; a piece of the only supernova remnant known visible to the unaided eye; the flattest galaxy known; the largest edge-on galaxy in the heavens; the brightest quasar; and the companion star to one of the first black hole candidates ever discovered. Each object is accompanied by beautiful photographs and sketches, original finder charts, visual histories and up-to-date astrophysical information to enrich the observing experience. Featuring galaxies, clusters and nebulae not covered in other Deep-Sky Companions books, this is a wonderful addition to the series and an essential guide for any deep-sky observer.","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":47107992715504,"sku":"9781139097383","price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781139097383_p0.jpg?v=1763699560","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781139097383","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
