Documentaries “The Sun”

Sun contains 99.86% of the mass in the Solar System

Isn’t that amazing. Who would tell that 99.86%, everything else (rocks, planets, dust) are just tiny, tiny, tiny, tiny parts of the Solar System.[1] Find this and other interesting stuff in the documentaries below…

A Glimpse of the sun’s power: How the auroras are formed?

I never asked myself this question but as I was searching about the sun, I found how auroras are created. First let me introduce you the Coronal Mass Ejection (CME). A CME is an explosion that occurs in the sun for several hours it happens when two different magnetic fields are brought together this results in the release of high energy particles (solar energetic particles).[1] [2] This massive explosions due to the high energy particles can affect the Earth’s magnetosphere by their enormous energy that turns into a geomagnetic storm thus affecting our electronic devices (e.g. making Gps inaccurate) [3] [4] See the article on for more information concerned to the video [5]

CME are the reason for the formation of the auroras along with the solar wind (plasma released on the upper atmosphere of the sun, consisting mostly in electrons and protons) [6]. When it approaches Earth, it triggers reactions that lead to the emissions of photons (that we perceive as visible light) [7].

I hope you liked and you learned something new!

How the sun sees you!

We are used to see in only one kind of electromagnetic waves, the visible light waves.[1]

What about ultraviolet waves, how do they make you look?

Sun has three different kinds of light that get into earth: infrared, ultraviolet and visible.[2] What we can only see is just the visible light. So have you ever thought about see in ultraviolet? How would you look?

Here is how the answer looks like…
