{"product_id":"0783421262294","title":"NOVA: Death of a Star","description":"In 1987, professional and amateur astronomers were able to witness a rare and remarkable occurrence: a supernova, a giant star that explodes into a massive object 20 times the size of the sun, and then collapses and dies. While many skywatchers were fascinated with this unusual and spectacular event, astrophysicists found it an ideal time to focus on their studies of just what causes a supernova, and what sort of matter and shock waves result from an exploding star. Nova: Death of a Star, a documentary produced for the acclaimed science series Nova, looks into the 1987 supernova event, and offers background on what scientists know about the exploding stars, and what they hope to learn from this sighting.","brand":"WGBH BOSTON VIDEO","offers":[{"title":"Default Title","offer_id":47085613809904,"sku":"0783421262294","price":19.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/0783421262294_p0.jpg?v=1763861099","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/0783421262294","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
