Merry Christmas and a happy holiday to everyone! I’m grateful your interest in the blog as well as your many comments and observations. Thank you! I hope Santa brought you a gift certificate for a hundred clear nights this coming year.
Enjoy the spirit of the day, and don’t forget to go out and see the spectacular pairing of Jupiter and the moon in the eastern sky tonight. As you relish the sight, consider that the planet we call home spins ceaselessly day and night. Watch it below.
The Earth spins at night. Pictures taken in infrared and visible light by the Suomi NPP satellite for nine days in April 2012 and 13 days in October 2012 were used to create a complete night map of Earth. It took 312 orbits to get a clear shot of every parcel of Earth’s land surface and islands.
