A star forms from massive clouds of dust and gas in space, also known as a nebula. Nebulae are mostly composed of hydrogen. Gravity begins to pull the dust and gas together.
2 de feb. de 2023 · Ans: All stars follow a 7-step life cycle from their birth in a nebula to ending up as stellar remnants. It goes from a Protostar to the T-Tauri phase, then the Main Sequence, Red giant or supergiant, fusion of the heavier elements, and finally a Planetary Nebula or a Supernova.
All stars form in nebulae, which are huge clouds of gas and dust. Though they shine for many thousands, and even millions of years, stars do not last forever. The changes that occur in a star over time and the final stage of its life depend on a star's size.

Star Lifecycle - NASA Science. Observe the formation of stars from the first stages to the formation of planetary systems. Inside The Pillars Of Creation. The Pillars of Creation in the Eagle Nebula captured in visible light by Hubble. Stellar nurseries are hidden within the towers of dust and gas.
Hace 2 días · A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form.
7 de feb. de 2024 · Star-Forming Nebula. How Do Stars Form in Nebulas? Stars are born in clouds of gas and dust. One such stellar nursery is the Orion Nebula, an enormous cloud of gas and dust many light-years across. Turbulence from deep within these clouds creates high density regions called knots.
