Goncharov, McWilliams, and the rest of the team's work on noble gases could ... in hydrogen. But neon behaved differently in the laboratory conditions mimicking the two gas giants.

Xenon's discovery concluded an intense period of research on noble gases. Much heavier than neon and krypton, it had not been explicitly predicted, and was sufficiently rare to avoid chance detection.

Neon lights rely on neon gas and other noble gases to emit light, while fluorescent lights use a phosphor coating inside the tube to produce their high-intensity glow. This is why fluorescent ...
