How can you tell if a signal from space is an alien communication?

...solar flares coming from the red dwarf star (a small and relatively cool star). Such stars are indeed prone to this type of activity, but the researchers say the radio pulses are unlike anything ever seen from other similar stars. Perhaps more likely is that the signals originate closer to home – arising as interference from a high altitude, Earth-orbiting artificial...

...oxide. A sunscreen contains chemicals that absorb the energy contained in the ultraviolet rays and reflect it away as lower-energy long-wave radiation, which is emitted as heat. [sun block versus sunscreen] Final thoughts A good way to limit exposure to UV light is to avoid being outdoors in sunlight too long. UV rays are most intense between the hours of 10 am and 4 pm....
