Other Objects in the Universe

Nebulae

A Planetary Nebula surrounds a dying star... (size on scale of solar system)‏

Some nebulae are results of massive, very unstable stars

V 838 Monocerotis

Some nebulae are stellar nurseries ... (These are many light years in size)‏

Some represent birth AND death Some represent birth AND death... (Eta Carinae lies within the Keyhole Nebula)‏

Supernovae

Supernovae are the death throes of massive stars

White Dwarf vs Neutron Star White dwarfs are the remnant of stars like our Sun Neutron Stars are the remnants of more massive stars White Dwarf vs Neutron Star

Quasars

Quasars are objects from the young universe (we don't see any nearby)‏

Perhaps Quasars are Active Galactic Nuclei Perhaps Quasars are Active Galactic Nuclei... (note the jets of gas coming from the nucleus of this galaxy)‏

Black Holes

They're not Black, nor are they Holes
