Stars-How They Are Formed Do you want to know how stars are born? Well here goes. The 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 crea...
How is Ethylthioethane formed? Why does fusion only occur in the sun's core? Describe the different fates of the different types of stars. Also, explain the differences between Type I and Type II supernovae. What forces are opposing one another throughout the life of a star and how do...
Such structures include multiple-ring systems, hourglass-shaped nebulae, and butterfly-type morphologies, and they are found around quietly dying Sun-like stars as well as around massive stars that explode as supernovae (see the figure). The formation mechanism of these structures is connected to...

How are planetary nebula formed? How are gas planets created? How many planetary systems are there? How does the transit method for detecting extrasolar planets work? How are asteroids formed in space? Where are rocky asteroids found in the solar system?
What planets can teach us about stars “We are probing the very limits of the star forming process,” said lead author Adam Langeveld, an astrophysicist at Johns Hopkins University. “If you have an object that looks like a young Jupiter, is it possible that it could have become a star ...
That a non singular version of such solutions exist is clear from direct observation of stars and BHs. As stated by Ellis [112], the concept of physical infinity is not a scientific one. The Big Bounce proposed here, based in Quantum Mechanics, could avoid both the BH and the Big Bang ...
How was the moon formed? Related: Earth's layers: Exploring our planet inside and out What is the core accretion model? Artist's conception of our solar system's solar nebula, the cloud of gas and dust from which Earth, the sun and our solar system's other planets planets formed. (...
There was no solar system, only a giant, rotating cloud of particles called the solar nebula. To figure out how all that leftover gas and dust led to planets, astronomers have largely studied the structure of our own solar system for clues. They've also looked to distant, younger solar ...
According to the solar nebula theory, the sun formed around 4.5 billion years ago from a massive cloud of gas and dust in space [source: NASA]. Imagine a huge cloud in space that shrinks and spins because of outside forces. This cloud becomes a flat, spinning disk, called a solar nebul...
