Other Objects

Some of Hubble's most instructive images sit outside traditional category boundaries. This section groups scientifically valuable targets such as supernova remnants, protostellar jets, gravitational lensing systems, and other uncommon classes. These observations often provide decisive evidence for physical processes that are difficult to isolate elsewhere, including shock propagation, relativistic effects, or transitional evolutionary stages. Although diverse, these objects share one trait: each adds a unique constraint to our understanding of the universe. Use this category when you want to explore the edge cases that often produce the most interesting scientific questions.
