Transient science is the study of things that change in the night sky; usually things that get brighter and then fade. 

So usually astronomers stare at the sky and nothing changes, and you're piecing things together. But every once in a while, something happens that changes on a human timescale; something like seconds, to minutes, to hours, to years. 

All space telescope missions can be considered transient missions. Roman in particular, is designed to be a transient survey machine. But Hubble and James Webb are critical, synergistic missions -- where James Webb can give us that really in-depth view of specific transients, while Roman can survey a large patch of sky and find the rarest objects that we can possibly see. 

We're trying to answer fundamental questions of "How did all this stuff get here?," "What formed them?," and "How will we see more in the universe?"
