Accretion Disk Just like objects in space orbit around planets or stars, the dust and gas that is being accreted into a protostar orbit around the protostar. This orbit gives the dust and gas angular momentum. Importantly, angular momentum is conserved just like linear momentum. This means that...
What is Earth made of? Interestingly enough, we don't exactly know. We can use magnetic fields and seismic waves to measure the densities and movements of material deep in the mantle, liquid outer core, and solid inner core of the Earth, which provides clues about its composition. We know...
Now the other theory is called the disk instability theory. The disk instability theory holds that gas begins the planet-making process, without a solid core. You see, most of the outer accretion disk would've been gas. We believe solid particles probably made up just one percent of the ou...
What is an accretion disk, and how does one form? What is a nebular cloud? What is a supernova explosion? What phenomena starts the collapse of the nebula? What is a planetoid? What is the Nebular Theory? What is an Oort cloud made of?
Earth, if cut in half, would be shown as layers, like a cake. It is made up of four main layers: the crust, the mantle, the outer core, and the inner core. Ingredients in Earth's layers include solid silicate-based rocks and liquid metals....
But we'd expect to see some sign of it, like flares or radiation from its accretion disk. And most large galaxies seem to have just a single supermassive black hole at their center. Top: This image shows what GD-1 appears to actually look like. Bottom: This image shows what computer ...
The event horizon and the accretion disk Theevent horizonis the black hole’s point of no return — anything that crosses it would need to move faster than the speed of light to escape the black hole’s gravity. Mathematically, this boundary is physically defined by a relationship between the...

What is Meteor Crater? Which event marks the beginning of a supernova? A) the onset of helium burning after a helium flash in a star with mass comparable to that of the sun B) the sudden outpouring of x-rays from a newly formed accretion disk C) the sudden collapse of an iron c ...
