{"product_id":"supernovae-von-undefined-1","title":"Supernovae","description":"\u003cp\u003ePlease note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Supernovae are extremely powerful and luminous stellar explosions and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval a supernova can radiate as much energy as the Sun is expected to emit over its entire life span. The explosion expels much or all of a star's material at a velocity of up to 30,000 km\/s (10% of the speed of light), driving a shock wave into the surrounding interstellar medium. Learn  more about supernovae, their causes and effects as well as their role in the universe in this book.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786130119072\"\u003e\u003ch3\u003eThe spectacular death of a star\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786130119072","offer_id":57464016044357,"sku":"9786130119072","price":236.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f09b1652-9da8-454f-b086-0e05e8980379.jpg?v=1775543065","url":"https:\/\/shop.autorenwelt.de\/products\/supernovae-von-undefined-1","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
