Skytree casts long shadow on Tokyo DigitalGlobe The Tokyo Skytree rises 2,080 feet (634 meters) into the sky in a satellite picture acquired on April 4. The Tokyo Skytree is considered the world's tallest broadcasting tower and the second-tallest human-made structure, so you should expect it to cast a blocks-long shadow on its surroundings in Japan's capital. The only building taller is the Burj Khalifa in Dubai - which rises 2,717 feet high, about six stories higher than the 2,080-foot Skytree. The Skytree offers a restaurant and observation decks as well as broadcasting facilities for eight TV networks and two FM radio stations. There's a shopping arcade next door that includes a planetarium and aquarium. The complex had its official opening in May and is expected to draw 32 million visitors a year - which is more than Tokyo Disneyland's typical tally. This picture of the Skytree and its tall shadow was captured on April 7 by one of DigitalGlobe's orbiting satellites, and ranks among the company's top 20 images for 2012. Facebook users have been invited to press their "like" buttons to vote for their favorite pictures over the next week. On Dec. 19, the field will be narrowed down to the top five - and then there'll be a Facebook vote for the year's top satellite picture. Check out DigitalGlobe's blog for more about the contest.
