As the star collapses, hot gas is ejected into space. This gas is ionized by radiation from the core, causing it to glow. This is the last phase in the life cycle of a low-mass star.View Video Only Save Timeline Video Quiz Course 16K views Forms and Structure of the Planetary ...
The type of star that creates a planetary nebula is a low-to-medium-mass star, like our sun, that is destined to turn into a red giant and then a white dwarf as it completes its life cycle. Despite the name, a planetary nebula has nothing to do with planets. It was given that ...
Exploring the Life Cycle of Stars For both amateur and professional observers, the Carina Nebula offers a chance to see regions similar to the one that birthed our own Sun and planets billions of years ago. Studying the starbirth regions in this nebula gives astronomers more insight into the ...
Peering Into the Life Cycle of Stars “We are witnessing the final chapters of a star’s life, a preview of the Sun’s distant future so to speak, and JWST’s observations have opened a new window into understanding these awe-inspiring cosmic events,” Barlow said. “We can use t...

‘cloud,’is in fact an interstellar cloud of dust and gas.Like the clouds in the sky, nebulae come in interesting shapes like flowers, insects, animals or people.This is how many of them get their names.There are four main types of nebulae.First, there are star-forming regions, also ...
giant stars die, they release great clouds of matter into space in violent explosions, which also result in brilliant cosmic displays like theEagle NebulaorCrab Nebula. These star remnants then become thebirthplaceof entirely new stars and planetary systems -- and so the galactic life cycle goes...
small size. Planetary nebulae came to be understood as a final stage of stellar evolution. Spectroscopic observations show that all planetary nebulae are expanding. This led to the idea that planetary nebulae were caused by a star's outer layers being thrown into space at the end of its life...
