what time is north light visible
Tiny particles stream from the sun in all directions. when they fall into the earth's atmosphere at the poles, they make a shimmering, colored glow in the sky. we call them aurorae
its radiation from the sun. the particles travel towards earth but they get caught in the earth magnetic Field most of it just gets thrown into space but some falls to earth causingNorthernn lights.
I presume you mean the northern lights, or aurora borealis. These occur when there is a coronal mass ejection (CME) from the Sun, which is attracted by the Earth's magnetic field, causing the atmosphere over the magnetic poles to glow. CMEs are currently very rare, because we are at solar minimum,so there hasn't been any good auroras in the past year or two. They should become more frequent as solar activity increases. They are more frequent, the closer you get to the magnetic poles. The north magnetic pole is in far northeastern Canada, so aurora are commonest in northern Canada, Alaska, and Greenland, and in northern Europe to a lesser extent.
The Sun gives off a little something called 'solar wind' which are charged particles such as protons, electrons and heavier particles which hit and collide with the Earths magnetic field (magnetosphere). The collision of the particles with the magnetic field causes them to enter an excited state. The different colours are produced when these excited particles react to the Oxygen and Nitrogen and other gases in Earths atmosphere.
The northern lights occur when a solar flare or prominence shoots out of the Sun's surface, the photosphere. That releases little charged particles flying out into space, known as the Solar Wind. When it hits the Earth's magnetosphere it collides wiith the atoms in the atmosphere and they emit into light known as the northern lights. The best place you could see them from is either the North or South Pole.
