Have you ever seen the Summer Triangle? The bright stars Vega, Deneb, and Altair form a large triangle on the sky that can be seen rising in the northern early spring during the morning and rising in the northern fall during the evening. During summer months, the triangle can be found nearly overhead near midnight. Featured here, the Summer Triangle asterism was captured last month from Gunma, Japan. In the foreground, sporting a triangular shape of its own, is a flowering 500 year old cherry tree, standing about 15 meters tall. The triangular shape of the asterism is only evident from the direction of Earth — in actuality the stars are thousands of light years apart in space.

🌌 你見過夏季三角形嗎？明亮的星星織女星 (Vega)、天鵝座的鵝 (Deneb) 和牛郎星 (Altair) 形成了一個大型的三角形，在北半球的早春早晨和北半球的秋季晚上都能見到它。在夏季的月份，這個三角形幾乎位於正上方，特別是在午夜時分。 🌙
去年從日本的群馬縣所拍攝的這幅作品中，前景是一棵已有500年歷史的櫻花樹，高約15米，恰好也呈現出三角形的形狀。值得注意的是，這個星座的三角形形狀只是從地球的角度看才顯現出來，實際上這些星星在空間中相距數千光年。 ✨
