Reading Passage

The Northern Lights are colorful lights that appear in the night sky near the North Pole. They can look green, pink, purple, or blue. Their scientific name is aurora borealis.

The Northern Lights begin with the sun. The sun sends tiny charged particles into space. Sometimes these particles travel toward Earth.

Earth has a magnetic field around it. This magnetic field helps protect our planet. It also guides some particles toward the polar areas. When the particles reach Earth's upper atmosphere, they meet gases such as oxygen and nitrogen.

When the particles hit these gases, energy is released as light. Different gases can make different colors. Oxygen often makes green or red light. Nitrogen can make blue or purple light.

People usually see the Northern Lights in cold northern places such as Alaska, Canada, Norway, Iceland, and Finland. There are also Southern Lights near the South Pole. Their scientific name is aurora australis.

Long ago, many people made stories about the Northern Lights because they looked mysterious. Today, scientists understand more about them, but they still feel amazing to watch.
