A collapsed star from which light cannot escape?
A black hole is a collapsed star with such a strong gravitational pull that not even light can escape from it. This phenomenon occurs when a massive star runs out of nuclear fuel and collapses under its own gravity. The boundary surrounding a black hole, beyond which nothing can escape, is called the event horizon.
A collapsed star which light cannot escape?
A collapsed star with gravitational pull strong enough to prevent light from escaping is known as a black hole. This phenomenon occurs when a massive star exhausts its nuclear fuel and undergoes a supernova explosion, leaving behind a dense core that collapses under its own gravity. The gravitational force of a black hole is so intense that it creates a region of spacetime that light cannot escape from, known as the event horizon.
What are two competing forces in a star?
The two competing forces in a star are gravity, which tries to collapse the star under its own weight, and nuclear fusion, which generates energy and causes the star to expand outward. These forces balance each other to maintain a stable, long-lived star.
How was the star deneb born?
Deneb is a massive blue-white supergiant star that formed from a nebula of gas and dust approximately 20 million years ago. The star began its life as a large cloud of gas that collapsed under its own gravity, triggering nuclear fusion at its core and causing it to shine brightly.
What happens when the gravity of a massive star overcomes neutron degeneracy pressure?
When the gravity of a massive star overcomes neutron degeneracy pressure, the core collapses under its own gravity, leading to the formation of a black hole or a neutron star, depending on the initial mass of the star. This process releases a tremendous amount of energy in the form of a supernova explosion.
Where do black holes get gravity?
black holes are stars which collapsed under their own gravity.
Why doesn't a main sequence star collaspe under its own gravity?
Becasuse a star is balanced by Hydrostatic equilibriumSee related question
What is the heaviest smallest object?
The heaviest smallest object is a neutron star. Neutron stars are incredibly dense remnants of massive stars that have collapsed under their own gravity, packing the mass of about 1.4 times that of the Sun into a sphere with a diameter of only about 12 miles.
Is a neutron star on the main sequence?
No, neutron stars are not on the main sequence. They are the remnants of massive stars that have undergone supernova explosions and have collapsed under their own gravity, resulting in a highly dense core composed primarily of neutrons.
Does a supernova have a collapsed star?
Yes, a supernova can occur when a massive star exhausts its nuclear fuel and collapses under its own gravity. This collapse can result in either a neutron star or a black hole, depending on the mass of the original star.

Is a super nova a giant explosion of energy?
no, its a massive compression of a star under its own gravity. it then turns into an extremely dense star called a red dwarf.
A star is a?
A star is a sphere of gas held together by its own gravity.
A sphere of matter held together by its own gravitational field and generating nuclear fusion reactions in its interior?
This describes a star, which forms when a sphere of gas collapses under its own gravity. As the star's core undergoes nuclear fusion, it produces energy that counteracts the force of gravity wanting to collapse the star further. This delicate balance between gravity and radiation pressure keeps the star stable and shining.
