Tyken's Rift
A Tyken's Rift was a massive rupture in space into which energy was absorbed. The rare anomaly was named after Bela Tyken, the Melthusian captain who first encountered it.

When Tyken was trapped in the rift, his analysis determined that a massive energy release might overload and dislocate the anomaly. Utilizing his cargo of anicium and yurium, Tyken was able to create an explosion of sufficient power, and subsequently escape through the ruptured center of the rift.

In 2367, the starship  became trapped in a Tyken's Rift containing an uncharted binary star system after discovering the missing Federation science vessel , whose crew had all killed each other. Succumbing to the same effects as the Brattain crew, the Enterprise crew eventually realized that their condition was being caused by mental transmissions from a telepathic alien trapped on the other side of the rift. By analyzing the messages being received in her dreams, Counselor Troi was able to determine that the alien was requesting that the Enterprise release hydrogen into the rift, where, in combination with a substance the alien would release, it would cause an explosion powerful enough to dislodge both ships. The plan was successful, and both the Enterprise and the alien vessel were able to clear the rift. ()

In 2371, the location of Tyken's Rift was labeled in the star chart Data and Picard were studying in stellar cartography aboard the . (, display graphic)

In 2399, Kestra Troi-Riker claimed that Captain Rupert Crandall of the Inside Straight had "been everywhere, from Qo'noS to Tyken's Rift". ()
