It is time to develop probes capable of discovery to such far away lands. It is not an easy task, but, Voyager proves distance and longevity is possible. Nearly 50 years later the technology is so advanced it should be a walk in the park.
NASA is an amazing program.
Probes have to send back data on environmental conditions as if a human being was traveling across the cosmos. Radiation, chemical content if any, O2, and H2O. Lots of measures including light and source. The probes are better off sacrificing picture capability for data units that analyze the environment around the probe. Hubble and Webb can do pictures. Heck they will probably be taking pictures of the probe.
