As a planetary nebula, a star can shed some of its outer gases without losing them all and the cycle can be repeated many times. As a nova, the star will blow out its outermost layers and eventually leave the core, which becomes a white dwarf star. As a supernova, a large star blows off all of its gases, leaving behind a pulsar or a black hole.
What else can I help you with?
How does a dying star shed its gases?
As a star runs out of fuel and starts to die, its outer layers expand and are pushed away by the strong radiation pressure from the core. This forms a glowing shell of gas called a planetary nebula. Eventually, the core collapses into a white dwarf, while the expelled gas dissipates into space.
A big ball of hot gases in space is called what?
A big ball of hot gases in space is called a star.
What is left when a planetary nebula dissipates?
When a planetary nebula dissipates, what remains is the core of the star that has shed its outer layers. This core, known as a white dwarf, is extremely dense and hot, gradually cooling over billions of years. The planetary nebula itself, which is the glowing gas and dust expelled by the dying star, eventually disperses into space.
What distinguishes a nebula and a star?
A nebula is a cloud of substances and gases that can form into a star. A star is a ball of hydrogen and helium with trace amounts of other gases. A supernova is the death of a star.
How hot is the heart of a dying star?
1000000 degrees

A dying star can shed its outer atmosphere as a planetary nebula?
My earth science book said as a globular cluster, so that's just a thought
What could happen to the dust and gases that are left behind after a supernova of a dying star?
They will be drawn into a larger cloud by gravitational attraction and eventually, this can form a stellar system.
What is a dying star that explodes?
a supernova
How old is Ring star?
As of October 2023, the Ring nebula (M57) is estimated to be around 1,500 years old. It formed from the outer layers of a dying star that shed its material, creating the colorful gas cloud we see today. This makes it a relatively young nebula in astronomical terms.
How is the moon not a star?
The Moon is not a star because a star is made of a gases.
A big ball of hot gases in space is called what?
A big ball of hot gases in space is called a star.
What star sheds a planetary nebula?
A star like our sun will shed a planetary nebula after its 'death'
Death of a star?
A star dies out when the gases that the star is made up of burns out
When light from a star passes though the star's outer gases what happens to some of the light?
Some of the light gets absorbed by the gases, causing them to heat up and emit light themselves. This creates an absorption spectrum with dark lines at specific wavelengths corresponding to the elements present in the star's atmosphere.
When all the gases are gone what happens to a star?
first of all, all the gases from the star can't be vanished as this is a scientific reason.
