Things of Importance



This video is interesting. At first it isn't all that interesting because you're like, cool, it's the Sun (I feel like "sun" should be capitalized) spinning around like a billions times. But then when you think about it more and more it becomes surreal. That's the Sun. THE SUN. Also watching the solar flares is fun and the word "heliophysics" is an awesome word. 

This is a composite of 25 separate images spanning the period from April 16, 2012, to April 15, 2013. In a video, NASA has also collected three years' worth of such images and set them in a new video.


Here are some cool facts about the sun (via Wikipedia):
  • it's almost perfectly spherical
  • it "consists of hot plasma interwoven with magnetic fields." That is so great. 
  • it formed about 4.6 BILLION years ago as a result of the gravitational collapse "within a large molecular cloud."
  • it controls the Earth. That seems like a "no duh" but it's something that I've never thought about before. It controls our weather and like all life (photosynthesis)
Of course there's a ton of other info about the sun - just read the Wikipedia page if curious - I'm no expert.
