A planetary nebula is a shell of illuminated gas surrounding certain dying stars. As a lower to medium-sized star dies, it will reignite its helium energy shell in short bursts called a thermal pulse.

Planetary nebulae form when. a star loses 8) The star sheds mass, producing a nebula T or F: A planetary nebula shines because the dust and gas are hot. Low mass star life cycle. nebula, protostar, star, red giant, planetary nebula, white dwarf, black dwarf.

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.

A planetary nebula is the glowing cloud of dust that is ejected from a dying star known as a white dwarf. Planetary nebulae are produced when a low mass star dies and they generally live less than

An Emission Nebula is a cloud of dust and gas in space that shine naturally, due to the gas being lit up by a light source within the nebula. Planetary Nebula's are a form of Emission Nebula.
