who discovered ]xenon
Xenon was discovered in July 1898 by William Ramsay and Morris Travers at University College London. They had already extracted neon, argon, and krypton from liquid air, and wondered if it contained other gases.
It is possible that a tenth planet, referred to as âPlanet X,â exists and is waiting to be discovered. Soon after German astronomer (a scientist specializing in the study of matter in outer space) William Herschel discovered Uranus in 1781, scientists noticed that Uranus was changing direction from its predicted orbit.
