When the Geomagnetic storm hits Earth, the magnetic field lines of the planet temporarily get disturbed, and the process releases extremely high magnetic energy. The energy and heat are enough to ionize oxygen present in the upper atmosphere and turn it into blue-green hues of light, which we know as Auroras. Northern Lights or Aurora Borealis in the North Pole and Southern Lights or Aurora Australis in the South Pole. Although auroras are usually green in colour, they can sometimes appear as pink or red too.Today's NASA…

CME is one of the most influential drivers of solar storms and leads to powerful Geomagnetic storms on Earth. According to NASA, they are huge bubbles of coronal plasma threaded by intense magnetic field lines that are ejected from the Sun over the course of several hours. Although CMEs usually occur with solar flares, they can occur on their own too, and have the potential to disrupt sensitive electronics on Earth, as well as affect power grids. Surprisingly, a CME doesn't need to strike Earth to have an effect.Just a…

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…
