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.
We see an emission nebula via a) reflected blue light from a nearby star. b) blue light emitted by hot (excited) hydrogen atoms. c) red light emitted by hot (excited) hydrogen atoms. X d) reflected red light from a nearby star. 10-10.

The gravity from the material in the outer part of the star takes its inevitable toll on the structure of the star, and forces the inner parts to condense and heat up. 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.

The ultraviolet light from the hot exposed core, called a white dwarf, causes the gases to fluoresce. Most noticeable is the red emission from the excited hydrogen and nitrogen, the green emission from doubly-ionized oxygen, and Planetary Nebula Flashcards | Quizlet.
19) Our Sun should become a planetary nebula in another five billion years. True 20) A star system may undergo two or more nova outbursts. True 21) Our Sun will eventually become a nova. False 22) Our Sun will never become hot enough for carbon nuclei to fuse. True 23) The density of white dwarf stars is about a million times that of the Sun. False
