In planetary science, planetary differentiation is the process of separating out different constituents of a planetary body as a consequence of their physical or chemical behavior, where the body develops into compositionally distinct layers; the denser materials of a planet sink to the center, while less dense materials rise to the surface, generally in a magma ocean. An open cluster is a group of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way Galaxy, and many more are thought to exist. They are loosely bound by mutual gravitational attraction and become disrupted by close encounters with other clusters and clouds of gas as Planetary Nebula A shell of gas from stars like our sun, at the end of their lifetime, there is no materials and they need to form a new star main sequence to red star What is a planetary nebula? Select one: a. the disc of gas and dust surrounding a young star that will soon form a solar system b.

A planetary nebula is quizlet

They have nothing at all to do with planets ; the terminology was invented because they often look a little like planets in small telescopes. Question 25 The sequence of events for the Sunlike star is planetary nebula, protostar, Sunlike star on main sequence, blue giant, red giant. 1/30/2018 Unit 3 Test: Astro 1 Game, Summer-1 2017, World Campus 15/30 stellar nursery, protostar, Sunlike star on main sequence, red giant, planetary nebula… Planetary nebula : If the diffuse nebulae are associated with the birth of stars, planetary nebulae are the remnants of stars. The name "planetary nebula" comes from the first observations of these objects sometimes have a circular aspect. End of life a star shines especially in the ultraviolet. The Ring Nebula (also catalogued as Messier 57, M57 or NGC 6720) is a planetary nebula in the mildly northern constellation of Lyra.

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 Death of Sun-like stars: Planetary Nebula. Some such bodies that are captured in the planet's gravity well become the most common type of meteorite by arriving A planetary nebula forms when a star can no longer support itself by fusion reactions in its center. The gravity from the material in the outer part of the star takes Planetary nebula, any of a class of bright nebulae that are expanding shells of luminous gas expelled by dying stars. Observed telescopically, they have a 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. The wispy Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains.
