Solen Planetarisk Nebulosa - Canal Midi
When helium fusion stops, the sun will…. A white dwarf is roughly the size of. The force of gravity at the surface of…. A planetary nebula is a glowing shell of gas that was once the outer layers of a star. The gas glows because the hot core's ultraviolet light ionizes the gas. The core, now exposed, will cool with time and become a white dwarf. Planetary nebula -Planetary Nebulae --what happens to the outer layer?
Diagrams What is a planetary nebula? The expanding shell of gas that is no longer gravitationally held to the remnant of a low-mass star Why is Supernova 1987A particularly important to astronomers? A nebula is an interstellar cloud of 90% hydrogen 10% helium and trace amount of heavier elements. Nebulae are the basic building blocks of our universe and contain the elements from which stars and solar systems are made. They are the biggest things in out galaxy.
Which type of nebula is so dense that it blocks the light coming from what ever is Planetary.

Planetary nebulae play a crucial role in the chemical evolution of the galaxy. They return to the interstellar medium material enriched in heavy elements, including carbon, hydrogen, oxygen and nitrogen; the stuff of life. A planetary nebula is created when a star blows off its outer layers after it has run out of fuel to burn. These outer layers of gas expand into space, forming a nebula which is often the shape of a ring or bubble.
