... 2000 September 16 . X-Ray Earth . Credit: Polar , PIXIE , NASA . ... Why does the Earth have an x-ray glow? Actually, the Earth itself does not, but the aurora high in the Earth's atmosphere do glow with x-rays detectable by space-based instruments. ... This activity causes shimmering visible aurora along with x-ray, ultraviolet, and radio emission . The x-rays are not dangerous to life on Earth because they are absorbed by the dense, lower atmosphere. ... About APOD | ...
