{"product_id":"voyage-to-jupiter","title":"Voyage to Jupiter","description":"The two Voyager encounters with Jupiter were periods unparalleled in degree and diversity of discovery. We had, or course, expected a number of discoveries because we had never before been able to study in detail the atmospheric motions on a planet that is a giant spinning sphere of hydrogen and helium, nor had we ever observed planet-sized objects such as the Jovian satellites Ganymedes and Callisto, which are half water-ice. We had never been so close to a Moon-sized satellite such as lo, which was known to be dispersing sodium throughout its Jovian neighborhood and was thought to be generating a one-million-ampere electrical current that in some way results in billions of watts of radio emission from Jupiter.","brand":"None","offers":[{"title":"Paperback","offer_id":46479107096786,"sku":"9781478221142","price":25.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/8980\/5233\/files\/1_d914c299-f586-4b03-88b4-4dd47e0b7ddf.jpg?v=1762813429","url":"https:\/\/www.indigo.ca\/products\/voyage-to-jupiter","provider":"Indigo","version":"1.0","type":"link"}
