Our Planet will take viewers on a spectacular journey of discovery showcasing the beauty and fragility of our natural world,” Attenborough said as the series was announced on Thursday. “Today we have become the greatest threat to the health of our home but there’s still time for us to address the challenges we’ve created if we act now. We need the world to pay attention.”

5,500-Year-Old Sumerian Star Map Of Ancient Nineveh and the Observation Of Köfels’ Impact Event

“For over 150 years scientists have tried to solve the mystery of a controversial cuneiform clay tablet that indicates the so-called Köfel’s impact event was observed in ancient times. The circular stone-cast tablet was recovered from the 650 BC underground library of King Ashurbanipal in Nineveh, Iraq in the late 19th century. Long thought to be an Assyrian tablet, computer analysis has matched it with the sky above Mesopotamia in 3300 BC and proves it to be of much more ancient Sumerian origin. The tablet is an “Astrolabe,” the earliest known astronomical instrument. It consists of a segmented, disk-shaped star chart with marked units of angle measure inscribed upon the rim.”
