Norwegian Aurora Borealis in HD

HD Aurora Borealis in Norway

An aurora (plural: aurorae or auroras) is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). The charged particles originate in themagnetosphere and solar wind and, on Earth, are directed by the Earth’s magnetic field into the atmosphere. Aurora is classified as diffuse or discrete aurora. Most aurorae occur in a band known as the auroral zone which is typically 3° to 6° in latitudinal extent and at all local times or longitudes. The auroral zone is typically 10° to 20° from the magnetic pole defined by the axis of the Earth’s magnetic dipole.

NASA produced video on the evolution of the moon over time up until its current status. It shows the different waves of meteorite impacts that eventually shaped our satellite as it is today, as well as its evolution over the millions of years since space dust and gasses started to be pulled together.
