NGC 634 is a spiral galaxy, lying 250 million light years away in the Triangulum constellation. This spiral galaxy was discovered back in the nineteenth century by French astronomer Édouard Stephan, but in 2008 it became a prime target for observations thanks to the violent demise of a white dwarf star.
