The oldest known nebula is the Cassiopeia A supernova remnant, which is estimated to be around 330 years old in human terms since its explosion was observed in the 17th century. However, in terms of its material, the remnants may contain elements formed in previous stars that are billions of years old. Other ancient nebulae, like the planetary nebulae, can also contain stellar material that is over 10 billion years old, stemming from the early universe. Thus, the age of nebulae can vary widely depending on how one defines "oldest."
