1 Core A

2 Preliminary Question Are there color differences between the Northern Lights and Southern Lights when viewed from space, and have they changed over time?

3 After studying the auroras, which were named after the Roman Goddess of dawn-Aurora, we have learned many things. The auroras have a specific color after which type of gas they encountered. We have learned that auroras are made at the openings of the Earth's magnetosphere at the north and south poles with protons, electrons, and solar wind mixing with gases to create certain colors. They usually appear as arcs, clouds, or streaks in the sky. The auroras can best be seen in the months of October, February, March, April, and December when the lights are at their longest and the sky is dark enough to see the lights. Auroras usually appear 20 degrees away from the poles, and they are seen approximately 25 times a year. They are made of solar wind collisions.

4 Are there color differences between the Northern Lights and Southern Lights when viewed from space, and have they changed over time?

5 We will use the Gateway to Astronaut Photography of Earth as our primary source of image data.Gateway to Astronaut Photography of Earth Any other sources of information and data will come from related web sites. We will target the regions near the upper northern and upper souther latitudes for images, since these are the regions in which the aurora can be seen. We will seek a minimum of 40 images for our research. Among the specific pieces of data that we will log from each image will be: image I.D., date, colors, focal length, whether the image is of the Aurora Borealis or Aurora Australis, and general observations. One question we have is if advances in photographic technology might impact the more recently taken astronaut photographs vs those taken by astronauts many years ago.

6 There are no measurable differences observed between colors seen in the Northern Lights and Southern Lights when viewed from space and when compared over time.

11 Aurora Australis has more colors than Borealis Could be corrupted because we have less pictures of Borealis viewed from space There is little to no change in the colors, or shape over time Our data listed above shows little to no changes as the years progress So it tells us that the gases, that make the color, haven't changed over time.

14 excited state The state of an atom when one of its electrons is in a higher energy orbital than the ground state. Atoms can become excited by absorbing a photon of a specific energy, or by colliding with a nearby atom Ionization is the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions. This is often confused with dissociation

15 Question: Hypothesis - There are no measurable differences observed between colors seen in the Northern Lights and Southern Lights when viewed from space and when compared over time. Are there color differences between the Northern lights and Southern lights when viewed from space, and have they changed over time? We believe this hypothesis is true, because our research showed no visible signs of color change between the Northern and Southern Lights, from space. There are also no visible changes over time.

16 Why can you see more colors from Earth than from Space? Is this because there might be more chemicals higher up in the sky so they can be seen better from space?

What they are and how they are made. 3.It tells the forecasts, the best time to watch the aurora, and that aurora makes no sound 4.I talks about Auroras and the scientific reasons they appear.
