When a star like our Sun dies, it doesn't explode into a supernova or collapse into a black hole. Instead, it gently sheds its outer layers, which form a beautiful cloud called a “planetary nebula”, while the dying star's core becomes a white dwarf.

What does a planetary nebula form?
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 nebula which is often the shape of a ring or bubble.
What happens when a star becomes a planetary nebula?
The planetary nebula phase is a final stage in a low-mass star's life. During this phase, the star sheds its outer layers. This creates an expanding, glowing shell of very hot gas. … Eventually it will form part of the clouds of dust and gas where new stars form.
How does a planetary nebula form into a white dwarf?
A planetary nebula is a special type of nebula made when the outer layers of an old, giant star are thrown off into space. A white dwarf is the small, faint and very dense star that remains behind after a planetary nebula has formed.
What does a planetary nebula surround?
A bright, colorful shell of gas and dust surrounding a star in the last stages of life. A planetary nebula is created when the star puffs off its outer atmosphere. The nebula usually looks like a doughnut, sometimes with the small, hot, rapidly evolving star visible in the center.
What is a planetary nebula quizlet?
A planetary nebula is the ejected shell of an evolved giant star. It is the shape of a spherical shell and is composed of relatively cool thing gas, which was once the outer part of the star. A planetary nebula is associated with the death of a low mass star. You just studied 15 terms!
How does a planetary nebula form quizlet?
A planetary nebula is formed when a red giant ejects its outer atmosphere. The beautiful images show that a planetary nebula is a stage in the evolution of a low mass star. They last tens of thousands of years. A white dwarf is the carbon core of a red giant that has ejected its photosphere as a planetary nebula.
What elements are in a planetary nebula?
A planetary nebula is a huge shell of gas and dust ejected during the last stage (red giant) of the life of a medium star. Elements such as helium, carbon, oxygen, nitrogen, neon and smaller amounts of heavier elements are present.
What type of star will form a planetary nebula?
white dwarf Smaller stars like our sun end their lives by ejecting their outer layers of gas into space over the course of about 10,000 years, leaving behind the star's hot core — a white dwarf. Radiation from the white dwarf causes the gas to glow, creating a unique and beautiful formation called a planetary nebula.
