Everyone is curious about the science behind Iceland’s stunning Auroras. The northern lights, known as the Aurora Borealis, are one of the most fascinating natural phenomena, and they are often seen in Iceland in clear and cold weather outside the city between September and March. This blog outlines how and why the Northern Lights occur and how the Icelandic Aurora is distinguished, including what makes Iceland unique to notice this magnificent phenomenon. If you want to visit this stunning beauty, you can plan day tours from Reykjavik, which provides an excellent opportunity to enjoy this beauty.
What are the Northern Lights?
Northern Lights occur high above the Earth’s surface, where the atmosphere has thinned to almost nothing at 100-250 km altitudes. Electrically charged particles make the thin air shine; in this way, it resembles a fluorescent light. Auroras around the geomagnetic poles are found in auroral belts, 20-25 degrees. Northern Lights was first identified in the original Old Norse as “norðrljós” in 1230 SD. It combines Aurora, the Roman goddess of Dawn, and Boreas, the Greek god of the North Wind; this name reflects the grandeur and otherworldly appearance of an auroral display.
Auroras result from the interaction between the solar wind and Earth’s magnetosphere. The solar wind is a stream of highly charged particles. As the solar wind interacts with Earth’s magnetic field, it streams down to Earth’s atmosphere and lights up the sky. Some trapped particles spiral back and forth along the magnetic lines of force-producing auroras. The colors of auroras are based on the altitude and the composition of the atmosphere. Although there’s substantial variety, green and white dancing are the two most common colors. Oxygen molecules create a reddish light at higher altitudes when solar wind particles strike them. The oxygen molecules can glow with a greenish hue in the middle, and nitrogen molecules are excited with a reddish boundary.
Iceland’s Appeal for Northern Lights Viewing
Iceland is well known as one of the top locations in the world, and it is ideal for watching the magnificent Aurora Borealis. It gives the best aerial sightseeing of this marvelous natural wonder and features superb panoramas that will be nicely framed for the auroras as background.
The Icelandic capital Reykjavik is conveniently located under the auroral zone, also known as the “aurora oval,” a region around the North Pole from where the Northern Lights can be seen most often. Therefore, Iceland is a perfect spot for stargazing and admiring the majestic auroras. There are times when the sky is darkest and clearest during a winter night in Reykjavik, the capital city, and you may observe the lights minimally from the city, too.
Prime Locations for Viewing
The wonders of Icelandic nature and the boundless areas on top of the sky lead visitors to the northern lights, where they can enjoy the chance to attend the beautiful shows. The most outstanding settings are the beautifully landscaped countryside, Thingvellir National Park, Snæfellsnes Peninsula, and Jökulsárlón Glacier Lagoon. In these areas (where city lights cannot be seen), you can truly enjoy the views and watch the stars’ incredible glory.
One of the engaging excursions is the Northern Lights Secret Tour leads you into the Icelandic wilderness far away from artificial light sources. Qualified guides will accompany us and will be responsible for keeping the lights in view. Transportation, critical commentary, and warm drinks are provided so that you can relax on the way. Other tours, such as the Northern Lights Deluxe Tour, Northern Lights Cruise from Reykjavik, ATV Northern Lights Tour, and the Secret Lagoon and Northern Lights Hunt Tour, allow adopting different perspectives and living various aspects of the Northern Lights.
The Science Behind the Aurora Borealis
The science behind the Aurora Borealis can transform our admiration of this widespread natural wonder from objective views into a deeper understanding. The Aurora Borealis can be attributed to only one factor: the reason behind it is the potential for thoroughly explaining the causes of this phenomenon.
When there is a lot of activity on the Sun, Earth can see this activity as the shimmering lights of Aurora Borealis. The ejection of charged atoms from the Sun causes such events. Impacts of solar storms occur when the fast-speed particles – charged electrically revolving to the Solar wind – finally hit our planet. Many of these particles are flung out, but they can still be captured by the magnetosphere of Earth and sealed in, which accelerates them to the poles. After hitting atoms and molecules in the Earth’s atmosphere, such particles cause heat, which is why the light is emitted and the show continues.
The different colors in the aurora are due to the charged particles pelting downwards, comprising oxygen and nitrogen molecules from Earth’s atmosphere.
The colors of the northern lights lend themselves to such gases as oxygen, nitrogen, and hydrogen neutral atoms. The additive of various color lights, such as green and violet, makes the fluorescence of nitrogen green. These fluorescent colors also cause purple, blue, and pink hints. At higher altitudes, oxygen can interact with solar particles, generating red areas formed by the interaction of oxygen with solar particles. The sky’s wavy lines and narrow curtains result from the Earth’s magnetic field, as it has a definite line of force.
Visibility in the UK and Other Planets’ Aurorae
Even though the Alaskan, northern Canadian, and Scandinavian regions are the best locations to see the spectacular southern lights displayed in circles around the Polar Regions, sometimes they can be seen in the United Kingdom. The probability of UK residents witnessing Northern lights depends on the area’s location and levels of light pollution. Hence, the aurora is more likely to be seen in the country’s north, especially on dark and fair nights.
Auroras are not limited to Earth; they are present on several other planets. In addition to different planets with atmospheres and magnetic fields like Jupiter, Saturn, Uranus, and Neptune, the Earth is the only planet with such a spectacular viewing phenomenon. Through scientific experiments, scientists have overwhelming images of the planetary aurora, which are excellent for the stunning beauty of these planets.
Increased Sun’s Activity and Its Significance
Solar activity heartedly participates in the happening and level of the northern lights. Solar flares are powerful ejections of the Sun’s surface that discharge charged particles into space streams. These particles could reach our planet and its magnetosphere, thus causing aurors to shine brightly. The Sun’s dangerous flares can also produce geomagnetic storms, making the auroras more visible and larger.
Geomagnetic storms and the implications associated with them. Geomagnetic storms happen when the mighty expulsions, aka coronal mass ejections on the Sun, launch boiling plasma clouds with billions of tons of materials running at an incredible speed. Bending the sun’s charged particles in Earth’s magnetic field can create such strong auroras.
A shift in solar activity cycles and aurora appearances solidifies these scientific discoveries.
Extreme solar activity displays 11-year cycles of lows and maxes. The previous peak of solar activity was recorded in 2014 during the climax of the solar cycle. Flare-ups are likely to return through the mid-2020s during the solar cycle peak.
On the other hand, aurorae can take place at any time, which implies that viewing these awe-inspiring displays is a continuous activity for those who live in high latitudes.
Conclusion
The Aurora Borealis is a strikingly fascinating natural phenomenon. Learning how science relates to the aurora borealis and finding conditions in Iceland that provide perfect views of them improves the experience. One of the most fascinating scientific facts about the northern lights is that solar magnetic activity, also known as solar storms, is their creator, adding to the overall wonder and mystique. Whether you find them in Iceland or elsewhere, viewing the aurora borealis remains a remarkable journey and connection to the beauty of our planet and the cosmos.
