Earth astronomers measure that two novas (sudden brightening of a star) occur simultaneously, one in the constellation Orion and the other in the constellation Lyra. Each is 2.5×103c·y from Earth, but in opposite directions. Observers in aspacecraft flying at 1000 km/h on a line from Orion to Lyra measure one nova to occurbefore the other. (a) Which nova occurs first? (b) How much time separates the twonovas? Assume Earth is an inertial reference frame.
