How did the star Alnitak begin its life?
Each star in the solar system starts out in a nebula, a cloud of dust particles and gas.
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, that's correct! Stars are born when gravity causes gas and dust in a molecular cloud to collapse under their own weight. This collapse creates high pressures and temperatures in the core of the forming star, eventually igniting nuclear fusion and creating a stable star.
Can condense and become concentrated enough to form a star and possibly planets?
A nebula is a large cloud of gas and dust in space. As gravity pulls the particles in a nebula closer together, it can cause the material to condense and become concentrated enough to form a star and, eventually, planets.
What is a star that has shed its outer layers which become a big cloud of gas and dust?
A star that has shed its outer layers, forming a large cloud of gas and dust, is known as a planetary nebula. This phenomenon occurs in the late stages of a star's life, particularly for stars similar in mass to our Sun. As the star exhausts its nuclear fuel, it expels its outer material, leaving behind a hot core that eventually becomes a white dwarf. The ejected gas and dust create stunning structures that can illuminate and enrich the surrounding interstellar medium.
A contracting cloud of gas and dust with enough mass to form a star called a(n)?
A contracting cloud of gas and dust with enough mass to form a star is called a molecular cloud or stellar nursery. Within these clouds, regions of higher density can collapse under their own gravity, leading to the formation of protostars. As the protostar accumulates mass and temperature increases, nuclear fusion eventually begins, marking the birth of a new star.
What is the first stage of a star creation?
A star is "born" in a large cloud of dust and gas called a nebula
What is a large cloud of dust and gas that becomes a star star?
That would be a nebula, which is an interstellar cloud of hydrogen gas, dust, and plasma. It is the first stage of a star's cycle.
A star begins as a?
As a nebula, a cloud of gas and dust.
What is a star called that begins as a large cloud of dust and gas?
A star that begins as a large cloud of dust and gas is called a protostar. It forms as gravity causes the dust and gas to clump together and initiate the process of nuclear fusion in its core.
A contracting cloud of gas and dust with enough mass to form a star?
a protostar
What does the word nebulae mean?
it is a cloud of dust and gas that is usually the start of a star
Formation of a star begins with a cloud of interstellar gas and dust called?
a nebula
What is a contracting cloud of gas and dust with enough mass to form a star called?
A nebula
Is a nebulae where a star is born?
Yes, a nebula is a cloud of gas and dust in outer space where new stars are born. As the gas and dust in a nebula begin to collapse under gravity, the material can eventually become dense enough to form a new star. These regions are known as stellar nurseries.
How did the star Alnitak begin its life?
Each star in the solar system starts out in a nebula, a cloud of dust particles and gas.
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.
Where is a star born?
Stars are born within dense regions of interstellar gas and dust called molecular clouds. These clouds can be found throughout galaxies, including our own Milky Way. The process of star formation begins when gravity causes the gas and dust within a molecular cloud to collapse and form a protostar.
