How does a stellar nebula become a star
WebNebulae are often star-forming regions, such as in the "Pillars of Creation" in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials "clum" together to form denser regions, which attract further … Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. This landscape of "mountains" and "valleys" … See more Nebulae exist in the space between the stars—also known as interstellar space. The closest known nebula to Earth is called the Helix Nebula. It is the remnant of a … See more Astronomers use very powerful telescopes to take pictures of faraway nebulae. Space telescopes such as NASA's Spitzer Space Telescope and Hubble Space … See more

Did you know?
WebFor example, the ‘normal star’ stage is a period when vigorous activity between strenuously opposed gravity and motion produces little moment-to-moment change. Cool nebulae make ideal stellar nurseries because the gas pressure in them is low. Gravitational collapse inside such nebulae begins when sufficiently dense regions develop. WebHomework #4 1- Describe how a planetary nebula forms. Note the mass range of the progenitor stars. What other object to you expect to find associated with a planetary nebula? A asymptotic giant branch star (hot non-burning carbon core) is the progenitor. The carbon core gains enough mass that it ignites. This burst of energy heart the core and quenches …

WebAs they did, a tiny bit of matter transformed into a whole lot of energy, and a star was born. In this way, our Sun came into being. The Birth of the Planets The material in the nebula not absorbed into the Sun swirled around it into a flat disk of dust and gas, held in orbit by the Sun’s gravity. This disk is called an accretion disk.
