When thinking about outer space at a much more basic level, I remember being taught to think of the word “vacuum.” And as the narrator says in the video I watched, the space between planets is far from empty. A unique aspect of the sun’s weather known as the solar wind fills up some of the space between the planets, and has extremely interesting physical elements and attributes. NASA’s website explains some elements of the solar wind including its unbelievably fast speeds but relative weakness compared to the winds produced within our atmosphere. That, to my relatively inexperienced understandings of strength and power in the universe, is surprising to me, as I probably would have guessed that anything emitted from the sun would be stronger than any counterpart emitted by the earth. Most interesting (and perhaps alarming) about the solar wind, though, is the comments made in the video regarding the ability to see the solar wind only with one’s eyes shut. Astronauts interacting with the solar wind cannot see it when they have their eyes open, but when they shut their eyes, the energetic particles interact with the fluid in their eyes and produce little sparks of light every few minutes, which can only be seen when one is awake with their eyes closed. This is just one small enumeration of the wonders of space, and the phenomenal universe which can create something which can be seen with eyes shut.
