Just recently we have seen the ”Mysterious Glowing Sea”. Now NASA is sending a satellite to specificly study a mysterious phenomenon called the ”glowing cloud” that has been spreading all around the world. The satellite should reveal whether the clouds are caused by global warming, as many scientists believe. “Noctilucent” clouds, which glow at night, form in the upper atmosphere, at an altitude of about 80 kilometres, and their glow can be seen just after sunset or just before sunrise. Just remember, now days whatever glows is mysterious !
