NASA says that on Sept. 13, the Solar Dynamics Observatory captured the event, which is believed to be a first of its kind. The observatory maintains constant watch of the sun, and as the moon moved into the picture, so did the Earth, completely blocking the view. The special event was recorded and shared by NASA on social media.
According to NASA, there was also a partial solar eclipse on Sept. 13, but it was only visible from parts of Africa and Antarctica.
