This video, made by Scientific Visualization Studio at NASA’s Goddard Space Flight Centre, Greenbelt exemplifies the appearance of the sun when viewed in different wavelengths.
These wavelengths, apparently can only be perceived by the telescope. So NASA’s Solar Dynamics Observatory (SDO) converts these wavelengths into an image human eyes can perceive, followed by colorization of light into a rainbow of colors.
Furthermore today (December 21st), the winter solstice will approximately happen at 1711 hours UT in the Northern Hemisphere; it is the time when the Sun reaches the southernmost declination in its yearly journey. At the same time – the summer solstice will happen in the Southern Hemisphere.
Today, you will be experiencing the shortest day and longest night of the year.
