Somehow the following hypothetical life form evolved in deep space with a long lifetime. It lives in a low orbit around massive stars, reproduces by eating interstellar gas and dust and uses the energy from the star to stay alive.
When the star begins to die, this lifeforms migrates to another one propelling itself with the rest of the collected energy.
Taking in account how it lives. Can withstand high radiation and heat, can live for a long time without food, Can travel astronomical distances only with its stored energy.
- What would its evolved body look like?
- is it organic?
- what shape and size such creatures may have?
- How they absorb energy?
- Which kind of propulsion they may use.
