NASAs Solar Dynamics Observatory shows two solar prominences, directly at opposite sides of the Sun, over a 26-hour period (Nov. 12-13, 2018).

Two solar prominences, directly at opposite sides of the Sun, rose up, twisted around, and fell apart at roughly the same time over a 26-hour period (Nov. 12-13, 2018). Prominences are cooler clouds of plasma suspended above the Sun by powerful magnetic forces. Although prominences are fairly common, it is uncommon to see two of them, about the same size, diametrically opposed to each other and lasting just about the same time. The images were taken in a wavelength of extreme ultraviolet light.
