An aurora (plural: aurorae or auroras; from the Latin word aurora, "sunrise") 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 the magnetosphere 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. During a geomagnetic storm, the auroral zone will expand to lower latitudes.

How the ionosphere can be used to provide a world wide link?
Radio signals under 30 MHz (give or take) are reflected off the ionosphere back to Earth, whereas radio signals over 30 MHz (give or take) normally go straight through the ionosphere. The maximum usable frequency (MUF) is the highest frequency reflected by the layers in the ionosphere. This frequency changes from day to night and with the seasons. It is also greatly affected by the 11 year sun spot cycle. Sun spots cause solar wind. This is a major cause for the ionisation of the ionosphere.
What is happens if a nuclear bomb thrown in the outer space?
When it detonates it produces new radiation belts captured in earth's magnetic field and produces Auroral displays near the poles. The radiation belts take a few weeks to dissipate and have severely damaged early satellites passing through them. One Gemini mission was delayed after a US nuclear test in space to avoid exposing the astronauts.

Are the Northern Lights in the Mesosphere?
The Thermosphere is one of the five principal layers of the atmosphere determined by temperature. The Auroras are formed in the Ionosphere, which is a parallel atmosphere layer so called because it is ionised by solar radiation. The Ionosphere usually overlaps both the Exosphere and the Thermosphere.Troposphere: 6 - 20 km above the surface of the earth - commercial jet aircraft.Stratosphere: 20 - 50 km - weather balloons.Mesosphere: 50 - 85 km - meteors.Thermosphere: 85 - 690 km - Auroras, Space Shuttle.Exosphere: 690 - 10,000 km - atmosphere is so thin that particles hardly ever come together.
What are advantages of point purchase display?
Point of purchase displays are placed near the cash register buyers standing here are more likely to make impulse purchases as they've already decided they know, like and trust you enough to spend their hard earned money. They are already standing there with their wallet out so it's easy to get them to take out a few more dollars. Make point of purchase displays eye catching and informative. They are a good place to place sale and discount items if you keep the sale fresh.
