A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars.
What else can I help you with?
What is the first stage in the life cycle of a star?
stellar nebula
Which stage comes first in the life cycle of a high-mass star?
The stage that comes first in the life cycle of a high-mass star is the main sequence stage. During this stage, the star fuses hydrogen into helium in its core, maintaining a balance between radiation pressure and gravity.
Which stage comes first in the life cycle of a low mass star?
Formation of the star out of a giant cloud of gas and dust.
What is the earliest stage of the life cycle of a star?
dust
What is a stable stage in the life cycle of a star?
The "main sequence".
What is the first stage in a star's life cycle?
The first stage in a star's life cycle is the nebula stage, where a cloud of gas and dust in space begins to collapse under its own gravity. This collapse leads to the formation of a protostar, which will eventually become a full-fledged star through nuclear fusion.
The third stage in the life cycle of a star?
The third stage in the life cycle of a star is the main sequence stage, where a star fuses hydrogen into helium in its core. During this stage, stars like our Sun are stable and shine steadily due to the balance between gravitational forces pulling inward and nuclear fusion pushing outward. This stage can last for billions of years, depending on the mass of the star.
Which of the following steps in a star's life cycle takes the longest?
The longest stage in a star's life cycle is the main sequence stage, where the star fuses hydrogen into helium in its core. This stage can last for billions of years for stars like the Sun.
How do you know if a star is at a different stage in its life cycle?
You can tell by its size and/or color.
Is a quasar the same as a galaxy?
No, it's a possible stage in the life cycle of a star.
What is the name for the portion of a star's life cycle when it uses hydrogen for fuel?
The portion of a star's life cycle when it uses hydrogen for fuel is called the main sequence stage. During this stage, the star fuses hydrogen to form helium in its core, releasing energy in the process. This is the longest and most stable stage in a star's life.
What stage of the star cycle is Altair star in?
Altair is still in the main sequence stage of a stars life. See related link for more information.
