Mysterious orange aurora seen in Canada puzzle scientists

India Today  

In a mysterious celestial spectacle, the skies over Canada were painted with an unusual orange hue due to an aurora, leaving experts puzzled. Auroras, commonly known as Northern Lights, are typically seen in shades of red, green, purple, and even pink, which are the result of excited oxygen and nitrogen atoms in Earth's atmosphere. According to a report on spaceweather, which tracks the solar developments, the red auroras are formed by low-energy electrons colliding with atomic oxygen at high altitudes, while green auroras are formed by higher-energy electrons penetrating deeper and colliding with atomic oxygen at lower altitudes. In reality, it is both red and green at the same time," Kjellmar Oksavik explained Oksavik also points out that Thomas's photo beautifully reveals the alignment of Earth’s magnetic field. The overlap of slower electrons colliding high up and more energetic electrons traveling further down into a much denser atmosphere naturally produces a yellow-orange glow, solving the mystery of the orange auroras.
