It was recentlly learned that our sun likely coalesced from the gas in a globular cluster containing some 3000 stars, probably about 10 light years across. The first million years or so of the sun's existence it shone by the light of gravitational collapse, from the heat of colliding atoms. Once the sun's core temperature reached a critical threshhold, nuclear fusion began to occur, producing the light of a "true" sun.
The sun drifted around the galaxy, about once every 220 million years, some 20 times until now. It will continue to do so for another three or four billion years, at which time it will gradually begin getting larger and hotter. As the hydrogen fuel is consumed, it will expand fairly rapidly (over about a hundred thousand years) into a red giant. It will burn that way for awhile, liberating lots of heat, and then collapse into a small bright white dwarf. As a white dwarf it will burn several billion years more, eventually fading to a brown dwarf before blackening out altogether.
What else can I help you with?
Is the sun or Antares farther along in its life cycle?
Antares is farther along in its life cycle than the sun. Antares is a red supergiant star, which indicates that it is nearing the end of its life and will eventually explode as a supernova. The sun, on the other hand, is currently in its main sequence phase and has a few billion years of life left before it evolves into a red giant.
What will be the next stage in the sun's life cycle?
The next stage in the sun's life cycle will be the red giant phase. During this phase, the sun will expand and become bigger, eventually engulfing the inner planets of our solar system.
How long is the main sequence in the sun's life cycle?
The main sequence phase of the Sun's life cycle has lasted for about 4.6 billion years and is estimated to continue for another 5 billion years. During this phase, the Sun fuses hydrogen into helium in its core, producing energy through nuclear fusion. Once the hydrogen fuel in the core is exhausted, the Sun will evolve into a red giant.
Identify what kind of a star is the sun?
The sun is a G-type main-sequence star, also known as a yellow dwarf star. It is in a stable phase of its life cycle, converting hydrogen into helium through nuclear fusion in its core. The sun's spectral classification is G2V.
What is the sun's role in the energy cycle?
The sun is the primary source of energy for the Earth's energy cycle. It provides light and heat energy which drives processes like photosynthesis in plants, resulting in the production of food and oxygen. This energy is then passed on through the food chain, sustaining all life on Earth.
What is the life cycle stages of our star the sun?
It is approx half-way through its 10 billion year life cycle.
What part of the life cycle is the sun at now?
It is commonly understood that the sun, at 4.567 billion years is in it's mid-life, or about 1/2 way through it's life expectancy.
What is the life cycle of earths sun and where is it now in its life cycle?
middle age
How many years does the sun have left on its life cycle?
I think ur a gay. when you die the sun will end on its life cycle! :D >>>Jushki
What is the stage sun life cycle?

Is the sun or Antares farther along in its life cycle?
Antares is farther along in its life cycle than the sun. Antares is a red supergiant star, which indicates that it is nearing the end of its life and will eventually explode as a supernova. The sun, on the other hand, is currently in its main sequence phase and has a few billion years of life left before it evolves into a red giant.
Does a complete life cycle have only 4 stages?
Well, evry life cycle starts with the sun. It depends. Like sun, monkey, banana, and a banana eats nothing.
How did oxygen form on earth?
from nuclear fusion on the surface of the sun when it went nova, but it was also formed by plant life through the calvin cycle
What is the star life cycle of the sun?
Life cycle of a sun like star. A sun like star will start out as a nebula to a protostar to a main sequence star to a red giant and into a white dwarf and will simply fade out.
When the sun reaches the end of its cycle its life cycle the expanded part will be released into space forming a?
yes
What will be the next stage in the sun's life cycle?
The next stage in the sun's life cycle will be the red giant phase. During this phase, the sun will expand and become bigger, eventually engulfing the inner planets of our solar system.
What is the driving force behind the movement of water through the water cycle?
The driving force behind the movement of water through the water cycle is the energy from the sun.
