A nebula ais one of the most beautiful deep-sky objects in the night sky. But what is a nebula? And how do these space clouds form?
How does a star produce heat and light? The reason a star glows is that it uses nuclear fusion to fuse hydrogen atoms into helium nuclei producing both heat and light. Scientists can determine what elements make up a star by looking at the emissions spectra of the light they produce. This...
What elements fuse during planetary nebula formation? Which layer of the Earth is unique among terrestrial planets? What elements are found in asteroids? What characterizes the planets that are closest to the sun? Which of the outer planets is most like Earth? How?
Free Essay: Research from a star called Veil Nebula is being studied by scientists from NASA to discover how it has expanded since the eighteen years it has...
What is the distinction between a nebula and a galaxy? What light elements are formed in the Big bang theory? Explain dark matter. What is the evidence for dark matter? Define "Black hole". What is the mass of the black hole?
It will only be a main sequence when it fuses to helium. Different-sized stars will fuse up to different types of elements, and small stars will only fuse to helium in the core. Enchanted Learning. The Red Giant Betelgeuse is one star that is believed to have left the Main Sequence and...
This cloud becomes a flat, spinning disk, called a solar nebula. In the middle of this disk, a baby star forms and gathers material around it. Small particles in the disk stick together and make bigger pieces, like building blocks, which turn into baby planets. When the baby star gets ...
but for a smaller star like the sun, the effect will be a bit less dramatic. The solar core will be compacted to an incredibly dense, hot state. At this point, the helium will begin fusing into heavier elements along with whatever traces of hydrogen remain in the outer layers of the su...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
Stars(like our own sun) are immense balls of gas that produce their own radiation. They can range from red supergiants to cooling white dwarfs that are the leftovers of supernovas, or star explosions that occur when a big one runs out of gas to burn. These explosions spread elements thro...
