We Take It So Much For Granted, Without It,

we would be deader than a Dodo's do do,


the Sun, which is the star at the centre of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light, ultraviolet light, and infrared radiation. It is by far the most important source of energy for life on Earth, a few fun, sun facts:

Surface temperature: 5,778 K

Mass: 1.989 × 10^30 kg

Radius: 696,340 km

Age: 4.603 billion years

Distance to Earth: 149.6 million km

and now using data from NASA’s Solar Dynamics Observatory, filmmaker Seán Doran composed an entrancing time-lapse of the sun’s glowing coronal loops during a month-long period,


the video project compiles 78,846 ångström-171 photographs from August 2014 that show the bright, curved structures, which are made of hot plasma, as they burst upward. Colorized in gold in the time-lapse, the arced loops often form a bridge between dark sunspots, or places where powerful magnetic fields breach the surface and flow into the massive star’s atmosphere,


this is defiantly a 2 mug of coffee video, as it runs for some 44 minutes, for other stunning glimpses at astronomical happenings, head to Doran’s YouTube, which features footage of Earth’s orbit, Comet Neowise, and the rugged topography of the Red Planet, all absolutely stunning.
