SAA 4

Hi everyone!
This SAA is from my student Eduardo.
And this is his summary:

New Sun Eruption May Supercharge Northern Lights


An image of the sun's activity, captured by NASA's Solar Dynamic Observatory, reveals solar prominences on its surface.

Today, everybody forgets to look the sky at least one time during the day, but even so, after billions of years, the sun light continues to reach the Earth with big power.

Day after day the scientists try to discover better renewable sources of energy and now some progress was obtained transforming the sun light in electricity to use in our home, car and industries.

In the interesting text published in the FOXNEWS site, you can see a few examples about the quantity of energy generated in the interior of the sun. Each ejection of matter

Is launched to the space in big speed (100,000 Kilometers/Second) and the plasma has temperatures around 1.5 millions of grades Celsius.

I believe one day in the future the man will find a way to use more efficiently all this energy we need.

The following video can help to illutrate this topic:
