Aurora Borealis

Thank you sixth and seventh grade for all your wonderful questions during our video conference today.

One of the questions asked was of the Northern Lights. To further answer your questions I thought I would borrow my fellow team member's words about the lecture we had with Roger Woloshyn, otherwise known as Starman.


"He explained how and why they appear so brillantly in the skies here. The Northern lights are a natural light display usually seen best at night and at the polar regions. The sun is a constant star. It does not change size or temperature. It is a ball of gas that makes energy all day. There are sunspots on the sun that are getting rid of energy. These bits of dust are shot off the sun and hit our Earth's outer space which then create a halo of light around the pole. The Aurora Borealis, another name for the Northern Lights, are most commonly green in color. Sometimes they are pink or bright red."


Here is a picture of Roger "Starman" Woloshyn:








For the next blog entry, look for our adventure in igloo building. Have a great weekend!
