Cherenkov radiation
Cherenkov radiation was a form of radiation produced by tachyons interacting with a planetary atmosphere. It was visible as a blue glow in the sky.

In 3190, while seeking evidence of tachyons to support his hypothesis that the Dark Matter Anomaly was a primordial wormhole, Commander Paul Stamets asked Cleveland Booker if he saw Cherenkov radiation when the anomaly destroyed . Since Booker could not recall, President T'Rina later mind melded with him to examine his memory of the event. She concluded that Cherenkov radiation was not present. ()
