What is Kristian Birkeland famous for?
Lived 1867 – 1917. Norwegian scientist Kristian Birkeland is best known for explaining the natural phenomenon of Aurora Borealis in great detail. He also invented two other scientific feats – the Birkeland-Eyde process for nitrogen fixation and the electromagnetic cannon.
Who first saw the aurora borealis?
According to Neil Bone (The Aurora: sun-earth interactions, 1996), the term aurora borealis–northern dawn–is jointly credited to have first been used by Pierre Gassendi (1592-1655) and Galileo Galilei (1564-1642), who both witnessed a light display on Sept. 12, 1621.
What causes an aurora borealis?
Bottom line: When charged particles from the sun strike atoms in Earth’s atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.
Who found the aurora borealis?
Pierre Gassendi
The 17th century astronomer, physicist and philosopher, Pierre Gassendi, saw the Northern Lights on a trip in the North and named them the Aurora Borealis. Aurora was the Roman goddess of dawn who woke up the world with her torch.
Where is the best place to see the northern lights?
What are the best places to see the Northern Lights?

- Ilulissat, Greenland.
Does Mars have aurora borealis?
The Hope spacecraft launched by the United Arab Emirates and orbiting the red planet since February, has captured unique images of these dancing atmospheric lights, known as discrete auroras. …
Can you touch Aurora Borealis?
Secondly, the aurora are essentially photon emissions from nitrogen and oxygen molecules, so you can’t really touch it (as much as you can ‘touch’ a sunbeam). Even the gas that emits the photons is extremely tenuous.
Can you predict Northern Lights?
It is difficult to predict the Northern Lights over the long term. Coronal mass ejections, which cause most of the solar storms and, therefore, stronger Auroras, are forecast 15 days in advance, but their strength and shape can vary once they get closer to Earth.
