  • Auroras - NASA Science
    Auroras are vibrant light displays created when energetic particles from the Sun interact with Earth’s magnetic field and atmosphere These events, also seen on other planets like Saturn and Jupiter, result in a range of colors depending on altitude and the atmospheric gases involved
  • Aurora Colors Mystery: How Ionized Particles and Atmosphere Layers . . .
    A vibrant aurora display revealing how ionized particles from the sun excite oxygen and nitrogen in different atmosphere layers, creating iconic green and red aurora colors
  • Auroras: The Northern and Southern Lights - Center for Science Education
    Particles from solar eruptions bombard Earth’s magnetic field and enter the atmosphere at regions called auroral ovals These particles interact with gases in the atmosphere, creating auroras
  • Aurora - Wikipedia
    An aurora (pl aurorae or auroras) is a natural light display in Earth's upper atmosphere caused by charged particles from the Sun colliding with atoms in the atmosphere These collisions excite oxygen and nitrogen, which then emit light of different colors such as green, red, and purple [1] When observed in high-latitude regions [2] they are called polar lights and aurora polaris In the
  • The Chemistry Behind the Northern Lights - by Kishore
    Auroras occur when charged particles from the Sun, mostly electrons and protons, stream toward Earth as solar wind When these particles reach Earth's magnetic field, they are guided toward the poles
  • Auroras: What makes them happen? - Exploratorium
    The short answer to how the aurora happens is that energetic electrically charged particles (mostly electrons) accelerate along the magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light
  • Aurora Fact Sheet | Blog | Nature | PBS
    An aurora is a natural light display in the Earth’s sky, predominantly seen in high-latitude regions Auroras are the result of disturbances in the magnetosphere caused by solar wind
  • The Science Behind Auroras – How the Northern Lights Are
    The aurora borealis is formed when energetic particles from the Sun, carried by solar wind, interact with Earth’s magnetic field These particles are funneled toward the polar regions, where they collide with gases in Earth’s atmosphere, producing colorful light displays
  • What causes auroras? | HowStuffWorks
    Auroras are indicators of the connection between the Earth and the sun The frequency of auroras correlates to the frequency of solar activity and the sun's 11-year cycle of activity As the process of fusion occurs inside the sun, it spews high-energy particles (ions, electrons, protons, neutrinos) and radiation in the solar wind
  • What are the northern lights? The aurora borealis explained
    The northern lights are caused by the Sun’s powerful magnetic field In this ultraviolet photo, the magnetic field appears as bright lines in the haze of charged particles above the star’s surface
