...full force away from the earth. But on March 10, when the sun's stately rotation brought the turbulent group of sunspots to a position more directly facing the earth, a second, only slightly less powerful flare erupted in the region. Eight minutes later, traveling at the speed of light, a blast of X ray and ultraviolet radiation seared the earth's upper atmosphere. Within an hour, high-energy protons began to arrive, followed in three days by a massive bombardment of lower-energy protons and electrons...
...most dramatic manifestation of the solar flare was the two-night, spectacular display of the aurora borealis, or northern lights, that awed Paul Avellar and millions of others. Arriving high-energy electrons, deflected by the earth's magnetic field, spilled into the upper atmosphere near the north and south polar regions, which are unprotected by magnetic-field lines. Acting much as does the electrical current in a neon sign, the electrons banged into oxygen atoms, causing them to emit red and green light...
...long been pre-eminent in human thoughts and actions. Almost from the beginning, people worshiped the sun as the beneficent provider of light and life, and as a god, called Ra by the Egyptians, Helios by the Greeks and Sol by the Romans. To the Aztecs, the sun god was Huitzilopochtli, whom they nourished with human sacrifices. Egypt's great pyramids at Giza were built with their sides aligned with the rising sun at the vernal equinox, and the temple complex at Karnak was dedicated to Ra. The ancient circle at Stonehenge, in England, was apparently constructed so that...
Also radiating from the solar surface is energy in the form of visible light, ultraviolet and X rays. Enough of this energy penetrates the atmosphere to deliver some 100 trillion kW of power to the earth. Reduced to more comprehensible terms, solar radiation amounts to 1.35 kW falling on every square meter of earth, a number that scientists call the solar constant...
There is nothing funny about this crimefighter. He also seems to have no qualms about crossing against the light, judging from the way he ploughs through the streets of Gotham in his snazzy black Batmobile...
