Nasa's Solar Dynamics Observatory captured images of the sun looking somewhat shocked or perplexed , who can blame it.
The Sun in 193 Ångstroms, a wavelength of extreme ultraviolet light.
The Sun as it appeared on June 4 in the three ultraviolet wavelengths of 171, 193, and 211 Ångstroms.

Quote:A giant mouth-like hole in the Sun about as wide as five Jupiters is blasting hot Sun breath in Earth's general direction.
It's not an actual hole in the Sun, but what is known as a coronal hole: a region where the Sun's magnetic field opens up, allowing the wind of solar particles constantly blowing from our Sun to escape more readily, sending a gust of material blasting through the Solar System.
If you look at the Sun in optical wavelengths (we don't recommend doing this without special equipment), you won't notice anything; but, because these regions are cooler and less dense than the surrounding plasma, if you look at them in ultraviolet light, they appear as large, void-like patches of darkness.
