What is a collapsed star called?Question:What is a collapsed star called?Answer and Explanation: Stars are actually just massive balls of gases that are held together by their own gravity. As long as the core of the star remains hot, the star will...Become...

What is a globular star cluster? Is the magnetosphere part of the atmosphere? Where is the magnetosphere located? What is the point when Earth is closest to the Sun called? Does the sunspot cycle influence Earth's climate system? How long do sunspots last?
When their fuel is exhausted, they become red giants and then white dwarves. When the core eventually cools and no longer emits light, it is called a black dwarf. High-mass stars have a much shorter life as they burn through their fuel much more rapidly. When a high-mass star runs out...
What is the professor's opinion about the disk-instability theory? A. It differs from the core-accretion theory in relatively insignificant ways. B. It does not take into account the amount of time needed for gas planets to form. C. It is more applicable to star formation than the core-...
A star that consumes hydrogen to form helium is called a "main-sequence" star for all the time it is a hydrogen-fusing object. When it uses up all its fuel, the core contracts because the outward radiation pressure is no longer enough to balance the gravitational force. The core temperatur...
There's the idea of a journey, which is quite poetic, but it's framed in a very scientific context. Here in their laboratory in Marseille, the scientists simulate the formation of a comet and its journey to Earth.有一个关于旅行的很有诗意的想法，但它是在一个非常科学的背景下形成的。在...
Star Formation | Process & Examples from Chapter 11 / Lesson 3 95K Explore the star formation process and discover what a star is made of. See the distinction between nebulas and protostars and read how a new star is born. Related to this QuestionWhat...
The energy, say, uh...radiated into space by a normal, so-called "main sequence" star, is...generated by the uh...the conversion of hydrogen to helium. Here, you may ask what a main sequence star is. OK...the main sequence refers to a major grouping of stars that uh... forms...
This material forms massive rotating disks around these black holes that gradually feed matter into them, a process called “accretion.” The accretion disk is held stable by the outward push of centrifugal force generated by its rotation and the inward force of the black hole’s gravitational ...
