ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photo by @babaktafreshi Big Bear above Yellowstone. The Old Faithful geyser is an icon within the world's first national park, designated in 1872. Yellowstone is home to many bears, but on this summer night I was photographing two celestial bears. Stars of the Big Dipper (a part of Ursa Major, or Big Bear) appear above the geyser. The north star Polaris in Ursa Minor (Little Bear) is on the upper right. Swipe to see the constellations, and explore more of the universe with me @babaktafreshi. #twanight #yellowstonenationalpark #bigdipper #geyser」8月20日 3時38分
