A dark hole hundreds of times bigger than the Earth has been spotted on the surface of the sun. A photo of the enormous “coronal hole” was snapped by a camera aboard NASA’s Solar Dynamics Observatory on Jan. 1, 2015.

According to TheHuffingtonPost this irregularly shaped hole spans about 400,000 kilometers at its widest point and Its total surface area is about 410 times that of the Earth. [see below for size comparison]

This photo of Earth and Jupiter gives a sense of the size of the coronal hole.
Coronal holes were first seen in photos taken by NASA astronauts in the 1970s. They aren’t holes in the usual sense. Rather, they’re colder, cooler regions where the sun’s magnetic field reaches out into space. The holes can remain visible for five years or longer, according to NASA.
