APOD 4.7- Starry Night of Iceland

Two months ago, over the Jökulsárlón glacial lake in Iceland, this astounding image was taken with a combination of six exposures. The image captures the two green auroral rings. The night sky was full of amazing objects that night as the Milky Way galaxy, the Pleiades, the Andromeda Galaxy and the aurora can be seen in the photo. The auroras were caused by a large coronal mass ejection from the Sun. The auroras are expected to become more frequent as the Sun moves toward the solar maximum, which will result in more coronal ejections.
