Although this is comparing an event to a massive body, for convenience a comparison could be made using the common currency of energy. The most powerful gamma ray burst ever recorded, detected by the Fermi gamma ray space telescope in 2008, was a little less strong than six thousand supernovae, about 9 x 10^47 joules of energy. If you turned that into mass, per Einstein's famous formula E = m c^2, you'd have about 5 times the Sun's mass expressed as energy - and although not as sudden and intense as some bursts, it lasted unusually long. By comparison, the most massive known black hole (that of quasar APM 08279+5255) is about 23 billion times the mass of the Sun - so if that were converted into energy it would be a bit under five billion times as much as the biggest known burst and one would be compelled to conclude there is more 'strength' in a black hole when these extreme examples are compared.
Other approaches might yield different conclusions; because gamma bursts are transient events it is certain there have been instances of significantly greater power than recorded to date; one might also consider whether the relativistic jet (and accretion disk) of the above quasar yields more electromagnetic radiation per unit time (or otherwise, total binding energy, or work done per unit time by the black hole) than the burst to which it is being compared, which might bring into question whether it is notionally "brighter".

∙ 15y agoYes. A nova is a aged star shedding layers of its outer surface through pulses. Over time, they can create planetary nebula as a result. The core star survives and indeed may undergo many novas before the star eventually dies out into a white dwarf.
A supernova (or supernovae) is a massive star basically undergoing a huge boom. While parts of the inner core can survive depending on the supernova type, for the most part the process blows apart most of the star. As a result, this can happen only once.
One note - stars that may go supernova can undergo what is sometimes known as a false supernova. While theories vary, it is believed that these are the result of a massive star, near the end of its life, undergoing the rumblings before it explodes. However, these rumblings can occur a day, a year, a decade, or many thousands of years before it finally explodes.

Why can gamma rays exit a black hole although light can't?
Strictly speaking, gamma rays don't exit a black hole; they are electromagnetic radiation just like visible light - although they carry a higher energy - and neither light nor matter can exit a black hole. However, a black hole can cause gamma radiation to be created near it - for example, by processes at quasars or active galactic nuclei, which, powered by a supermassive black hole, can generate immensely powerful jets or beams which can accelerate particles to relativistic speeds, boost lower energy photons, and generate powerful x-rays and gamma rays. Another possible source of gamma rays is the so-called black hole evaporation, through which a black hole could potentially lose its mass and end its life with an explosive gamma burst.
What is it called when a black hole explodes?
One common term used is black hole evaporation. This relates to a mechanism wherein the black hole's mass is gradually lost through Hawking radiation; but the rate of loss is inversely proportional to the black hole's size and thus accelerates as it shrinks. At the moment it vanishes it is thought to do so with a burst of gamma radiation; the Fermi space telescope is intended to search for such gamma flashes.
What makes a black hole stronger?
If a black hole is more massive (it has more mass), it will have a stronger gravitational attraction.
How does a black hole admit gamma rays?
Just like any matter, light or other electromagnetic waves (this includes gamma rays), if they happen to get within the black hole's event horizon, will just get absorbed, slightly increasing the mass of the black hole.
Do Gamma ray burst form a black hole?
In an indirect way, yes. Gama rays are the highest-intensity form of electromagnetic energy. They usually indicate a very power energy source. Most black holes are formed by exploding stars called supernovas. These events can be detected as gamma ray bursts.
What would happen if you shot a black hole straight though the center with a gamma ray burst?
The gamma rays would be absorbed, the black hole's mass would increase.
What is the brilliant light given off by a black hole?
Its Gamma burst Ray which comes from the center of the universe.

What is the age of the average black hole?
Unless scientists were to detect the gamma-ray burst that might herald the birth of a new black hole, there is not even a theoretical way to measure the age of a black hole. So the answer to this question, like so many questions in astrophsyics these days, is "We don't know".
What makes a black hole stronger?
If a black hole is more massive (it has more mass), it will have a stronger gravitational attraction.
Which is stronger black hole or neutron star?
Gravity is stronger in a black hole, if that's what you mean. It's in a black hole that space and time are distorted to such an extent that not even light can escape.
How does a black hole admit gamma rays?
Just like any matter, light or other electromagnetic waves (this includes gamma rays), if they happen to get within the black hole's event horizon, will just get absorbed, slightly increasing the mass of the black hole.
How does a quasar burst away from a black hole if the black hole has infinite gravity?
It's only infinite around the event horizon.
Can gamma ray pass through black hole?
No. Nothing can pass through a black hole. Once something enters it can never leave.

In an indirect way, yes. Gama rays are the highest-intensity form of electromagnetic energy. They usually indicate a very power energy source. Most black holes are formed by exploding stars called supernovas. These events can be detected as gamma ray bursts.
What is formed from a black hole?
Black Holes end up producing large quantities of gamma rays throughout their lives. This is one of the processes that lead to a Black Hole's demise.
