Stars like Earth's Sun most likely formed directly from the gravitational collapse of regions within molecular clouds, also known as stellar nurseries. These dense regions contain gas and dust, primarily hydrogen and helium. As the material collapses under its own gravity, it heats up and eventually forms a protostar, which continues to gather mass and eventually ignites nuclear fusion, becoming a main-sequence star like the Sun.
What else can I help you with?
What kind of cluster did our sun form in?
Our sun formed in a cluster known as a stellar nursery, which is a cloud of gas and dust where stars are born. The sun likely formed in a cluster with many other stars around the same time, but has since drifted away from its birth cluster.
What is the likely reason that you cannot find any examples of the first generation stars?
First generation stars are believed to have formed shortly after the Big Bang, making them extremely old and therefore difficult to observe. Additionally, these stars are thought to have been massive and short-lived, likely turning into black holes or exploding as supernovae before leaving behind any detectable remnants.
How do dying stars form planets?
They don't - new born stars and planets are formed together.
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.
What elements are formed in cool stars?
In cool stars, elements such as hydrogen and helium are primarily produced through nuclear fusion in their cores. Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.
Simplified explanation of the formation of uranium in the earths' surface?
Uranium was not formed on the earth but in the stars by stellar nucleosynthesis.
How are blue stars formed from protostars?
All stars are formed from protostars.
Was the Orion nebula a nova or a supernova?
The Orion Nebula was not formed from a single supernova or nova event. It is a stellar nursery where new stars are currently being formed. The nebula is created by the glowing gas and dust illuminated by newly formed stars within it.
Are new stars formed from the material of old stars?
Due to the scientific law that states that matter cannot be created nor destroyed, it is extremely likely that all of the stars in our universe were formed from older stars that had released some or all of their matter.
How long have Neutron stars been in the universe?
The first neutron stars likely formed some time in the first 600 million years after the Big Bang when large stars of the first or second generation died.
What does earths atmosphere do to starlight?
Makes stars twinkle.
Stars are formed from clouds of dust and gas called?
Stars. That is how stars are formed. They form from nebulae.
What kind of cluster did our sun form in?
Our sun formed in a cluster known as a stellar nursery, which is a cloud of gas and dust where stars are born. The sun likely formed in a cluster with many other stars around the same time, but has since drifted away from its birth cluster.
What is the fuzzy cloud around the stars?
Stars appear to twinkle and are fuzzy due to the earths atmosphere
What is the birthplace of celestial stars?
Stars are formed in a nebula.
Does the earths atmosphere make it impossible to see other stars?
No
What is the measurement of the amount of a stars light received on earths?
Parallax
