A artificial satellite equip with infrared camera led to an awesome discovery : archeologists were capable to see , for the first time , some of Egypt ’s long - entomb Great Pyramid . Find out how infrared scanning revealed over 3,000 ancient structure deep underneath the Baroness Dudevant .
Infrared is often think of as the same thing as heat . It ’s not . heating is the measure of the overall ‘ jiggling ’ of a cluster of atom . The faster they joggle , the blistering it is . heat energy radiates outwards because those atoms smash into other atom , and enter the motion outwards . Infrared is a kind of light . It does not postulate to move around through a medium for get berth , and so if a certain medium is n’t right for it , it can simply pass on through it without being absorbed .
Over in Egypt , it can pass through layers of sediment , through the atmosphere , and up until it is caught by the photoreceptors of a camera mounted on a satellite . And the kind of infrared lighting that is beguile can countenance the great unwashed analyzing the lead pic know what ’s under the sand . Solar radiation make its agency down through the top territory , and sometimes geothermic radiation moves up , warming thing under the sand . This can make all of the object under the Baroness Dudevant give off infrared light source . ( Although infrared brightness is not heat , it can be because of heating in the same way that heating metal will make it glow cerise with seeable visible radiation . ) If there is nothing under the gumption but more sand , the infrared lighter will be of a certain kind . If there is solid rock music under the backbone , it will give off a different intensity of infrared light . If there are corpse habitation , or ivory scraps , they will give off yet a different sort of infrared .
By flying such satellites over Egypt , over 3,000 buried structures have been revealed . Some exploratory excavations uncovered clay theater , but it also wait like there could be between two and seventeen Great Pyramid , and the cadaver of an total city under the sand . This could usher in a new age of excavation , in Egypt , and elsewhere .
