On Christmas Day, there was a full moon, the first since 1977. It reached its peak at 4:11 a.m. Mountain time.

This full moon, the last one for 2015, is called a Full Cold Moon because it happens during the start of winter.

NASA has a spacecraft currently orbiting the Earth’s moon. Its Lunar Reconnaissance Orbiter mission has been investigating the moon’s surface since 2009. The space agency says the mission has collected a “treasure trove of data” and is “making an invaluable contribution to our knowledge about the moon.”

A full moon on Christmas won’t happen again until 2034, nearly two decades from now, NASA said.

Among Native Americans, it’s the Long Night Moon, or vskihyi, the snow moon (Cherokee), or “when the wolves run together” as in Cheyenne, or kyaamuya, (Hopi, moon of respect), it represents the same thing: The light is returning.
