Yellow-Green [100-300 km (60- 180 mi)]: Vivid lime green is the most common color of the aurora. It comes from monatomic oxygen (O), but while the red aurora comes from oxygen absorbing solar radiation, green comes from oxygen atoms colliding with lower-energy electrons released by excited nitrogen molecules (N 2 + ).

2024年11月20日 · Yellow and pink auroras are rare and are typically associated with high solar activity. These colors result from a mixture of red auroras with green or blue auroras.

16 小时之前 · Also known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather.When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

2 天之前 · Yellow aurora borealis. Very occasionally, we get to see a yellow aurora. This is caused by a combination of oxygen and nitrogen molecules. This colour mixing sometimes produces shades of orange, too. White aurora borealis. When the northern lights are faint, they can appear as a milky-white shimmer in the sky. They can also appear as a grey or ...

2023年12月25日 · Yellow and pink auroras are also uncommon and linked to heightened solar activity. They are occasionally observed in displays, resulting from a combination of red with green or blue hues. Check...

2023年8月23日 · From dazzling green and pale yellow to elusive red and ethereal purple, this article uncovers the science and magic behind each hue of Auroras! What Is the Aurora Borealis? The Northern Lights, also known as the Aurora Borealis, are one of nature's most dazzling displays of light and color.

2018年9月6日 · Colors produced may be pink, red, yellow, green, blue, or violet. Occasionally, orange or white are produced. Typically, nitrogen will produce red, violet, or blue. Oxygen usually produces green or yellow. Reds generally are emitted above 240 km, greens at 100–240 km, purple and violet above 100 km, and blues at 80–100km. [1]

Very occasionally, you can see yellow and pink in an Auroral display which are associated with only high solar activity as they are simply a mixture of red with green or blue. Most solar particles typically collide with our atmosphere at an altitude of around 60 to 150 miles where there are high concentrations of oxygen.

2024年2月18日 · What is Aurora Borealis? The Aurora Borealis, also known as the Northern Lights, is a natural light display that typically occurs in the Earth’s northern polar regions. The lights are caused by the interaction of charged particles from the …

2024年5月13日 · Copper atoms give a blue light, barium is green, and sodium atoms produce a yellow–orange colour that you may also have seen in older street lamps.
