Celestial bodies like stars, black holes, and active galaxies emit electromagnetic radiation. Astronomers today are equipped with sophisticated instruments to detect those various radiations. In this journey, students are exposed to the ways in which different radiations reveal varied information about the cosmos. They will learn about gamma rays, x-rays, UV radiation, visible light, infrared radiation, microwaves, and radio waves, as well as how telescopes work. Complete set includes one large Electromagnetic Spectrum chart (51? x 35?), 14 informational charts (16? x 12?), and a teacher’s guide.
