What is the life cycle of a star in order?
Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
What are the stages of the Star How did a star form?
Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 – A region of condensing matter will begin to heat up and start to glow forming Protostars.
How can a star die?
Stars die because they exhaust their nuclear fuel. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.
What is a dying star called?
supernovae
Are dying stars bright?
The gas being puffed off by the dying star is much brighter when compared to the image of the nebula at the right, captured in January 2016 using the Wide Field Camera 3. All stars, even our Sun, will someday eventually die.
What will happen if a star dies?
When the helium fuel runs out, the core will expand and cool. The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf. This entire process will take a few billion years.
How fast does a star collapse?
70,000 meters per second
Does a supernova occur every time a star dies?
Star death On average, a supernova will occur about once every 50 years in a galaxy the size of the Milky Way.
Why does a star collapse into a black hole?
When the cores collapse to form dense stellar objects called neutron stars, they blast off the outer layers of the star in a supernova. When the core collapses, the blast wave slams into the dense material above, which thwarts the explosion. Instead of creating a supernova, the star implodes, forming a black hole.
Could the Sun become a black hole?
No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
Is the sun yellow in space?
It is a common misconception that the Sun is yellow, or orange or even red. However, the Sun is essentially all colors mixed together, which appear to our eyes as white. This is easy to see in pictures taken from space. Each color in the rainbow (red, orange, yellow, green, blue, violet) has a different wavelength.
What is the real color of sun?
white
Why are sunsets red?
Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. So at sunrise and sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red and yellow light remaining.
Is the sun on fire?
The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core.
Can you light a fire in space?
Fires can’t start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.
Does fire exist in space?
In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process. In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process.
Can fire exist without oxygen?
A fire cannot burn without oxygen. It should be noted that in the presence of carbon, nitrogen and oxygen, stars heavier than the Sun may burn hydrogen to helium by using the C, N and O as catalysts. Even in these stars, however, an absence of oxygen does not prevent nuclear burning.
