[ad_1] NASA’s Astronomy Picture of the Day is a mesmerizing snapshot of Auroras spiralling over the night-sky in Iceland. Scientists have long studied Auroras to better understand the workings of Earth's magnetic field and the solar wind. Auroras, also known as the Northern and Southern Lights, put on a mesmerizing show of lights in the night skies of the polar regions. Although auroras are usually green in colour, they can appear as pink sometimes too. Green auroras are formed when energy particles hit the oxygen atoms at 100 km to 300 km from the surface of the planet. But when particles hit at a height lower than 100 km, it results in the formation of pink auroras.NASA's Astronomy Picture of the Day is a mesmerizing snapshot of Spiral Auroras captured over a rock arch in the northw...

[ad_1] NASA’s astronomy picture of the day is an enthralling image of the Northern Lights or Auroras over Northern Canada. Although geomagnetic storms can cause various effects which have the potential to harm Earth, they're also the reason behind one of the most beautiful natural phenomena - Northern Lights. Auroras or Northern lights are shifting curtains of light in greens, blues and pinks which light up the night sky in the Northern and Southern poles. They are called Northern Lights or Aurora Borelis in the North Pole and Southern Lights or Aurora Australis in the South Pole. Although they are often caused by Geomagnetic storms, auroras are a sight to behold for astronomers as well as night-sky watchers. NASA releases its Astronomy image of the day on a daily basis.
