Man films awesome aurora on a plane! Video is viral; know how a solar storm sparks this light show

[ad_1] Auroras, commonly known as Northern Lights, are a rare sky phenomenon that result in stunning streaks of colourful light in the sky near the polar regions. However, there are instances where these flashing lights have also appeared across the world, especially if the solar storm that causes them is of strong intensity. Recently, people on a flight to Europe bore witness to a mesmerizing aurora that was snapped by a user, and the social media post has gone viral since then.Auroras captured on a flightInstagram user Vincent Ledvina, who calls himself ‘The Aurora Guy', shared a breathtaking video of auroras that were seen during a flight. In an Instagram post, Ledvina wrote, “Have you ever seen the northern lights from a plane!?” The mesmerizing auroras were snapped as the plane cro...

NASA Astronomy Picture of the Day 19 April 2023: Wow! Geomagnetic storm sparks auroras

[ad_1] 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 Astronomy Picture of the Day is a stunning snapshot of auroras lighting up the sky in Saariselka, in northern Finnish Lapland. It was a result of a powerful CME hitting Earth and the auroras could be seen not only in the North, but as far as New Mexico, according...

CME storm effect! Sun sparks auroras without even hitting Earth

[ad_1] 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 couple of days ago, a CME passed close by Earth and this caused, what is known as a, 'Ripple Effect'. According to a report by spaceweather.com, the interplanetary magnetic field near Earth suddenly rotated by almost 180 degrees. This usually occurs when a CME pas...

NASA Astronomy Picture of the Day 11 January 2023: Auroras spiralling in the Icelandic sky

[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...

NASA: Wow! Mesmerizing image of Northern Lights shared by astronomer

[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. Today's im...
