Every relation drawn, in words4
- Eagle Nebula (Messier 16) and the Pillars of Creation · instance_of · Giant molecular cloud
The Eagle Nebula pillars are dense molecular gas and dust within an active star-forming complex.
- Planetary nebula · supplies · Giant molecular cloud
Ejected AGB envelopes return carbon, nitrogen and s-process elements to the interstellar medium as the nebula disperses.
- Protostar · derived_from · Giant molecular cloud
A protostar is a collapsed and heated core of a molecular cloud, and no other environment is known to produce one.
- Supernova · supplies · Giant molecular cloud
Supernova ejecta return iron-peak and lighter heavy elements to the interstellar gas from which later generations of stars form.
