It was the "Astronomy Picture of the Day" (APOD) on September 13, 2004. It was also presented to his 8.03 students as a challenge to obtain extra course credit if they were able to explain this phenomenon. On December 7, Prof. Lewin revealed the physics (and demonstrated it) in lecture 22. The solution was also revealed by APOD to the many thousands of people who were puzzled by it and who tried to explain it. 1.
