Birth of a star definition
A star is an astronomical object comprising a luminous spheroid of plasma held together by self-gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known st… Webdefinition Formation of Stars A star will typically form from a nebula, a gaseous cloud with some combination hydrogen, helium, and dust. When the core of a star becomes dense …

WebThe birth of a star begins when massive clouds of dust and gas start to collapse and break down. How does this happen. It happens through the force of gravity. Gravity bounds the elements together to create a Protostar. The protostar is basically a baby star, and grows into a star through its life cycle in the same way we are born and grow. WebStars are born out of the gravitational collapse of cool, dense molecular clouds. As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores. These protostars rotate faster and increase in temperature as they condense, and are surrounded by a protoplanetary disk out of which planets may later form.
