A nebula, often circular or ring shaped, formed by the ejection of the outer layers from a late-stage, low-mass star. an expanding shell of gas surrounding a dying star, formed from matter ejected from the star's outer layers; the gas is ionized by the remaining hot stellar core, emitting light in the process Word Origin for planetary nebula C18: named from its (occasional) resemblance to a planetary disc A planetary nebula is a beautiful object created during the final stages of the life of a star whose birth mass was between 1 and 8 solar masses. Once it had been thought that, as planetary nebulae occur only late in the life of a star (for stars of an initial mass of 1 solar mass, after about 10 billion years), and these stellar swarms tend to dissolve in times shorter than that needed for a star to evolve in a planetary nebula (typically, less than 1 billion years); low-mass stars of less than about 3 solar masses have considerably A planetary nebula is a(n): A) contracting spherical cloud of gas surrounding a newly formed star in which planets are forming. B) expanding gas shell surrounding a hot, burned-out stellar core.

Planetary nebula is the gases that are shed from the outer layers of a red giant star in its final stages. A star like our sun expands to red giant at the end of its main sequence, and the outer layers are puffed out into space, drifting outward. This gas forms the planetary nebula.

Description. Ellis Grayson Bond (EGB) 6 is a large, planetary nebula in the constellation of Leo at RA 09h 53m and DEC +13d 44m 50s having a size of 11′ x 13′ with low surface brightness. This faint nebula was discovered by Bond in 1984 from Palomar Sky Survey prints. It is 1,500 light years distant with an age of ~60,000 years. The Helix Nebula, NGC 7293, lies about 700 light-years away in the constellation of Aquarius (the Water Bearer).

They are so named because their appearance through a small optical telescope closely resembles a giant planet. […] “Nebula” is just Latin for “cloud.” A couple of hundred years ago, when a fair number of well-heeled people started building big telescopes and observing with them, a “nebulosity” was an object that wasn’t a planet, but couldn’t be focused into a Depending on their individual masses, AGB stars are only 100,000 to 20 million years away from becoming planetary nebulae.
