Is a quasar more powerful than a hypernova?
A single GRB or hypernova, while devastating to anyone unfortunate caught in the damage path, won’t be able to completely reshape a galaxy. In contrast, quasars stay lit for almost a billion years or two, shining with the power of thousands of galaxies.
Is there something more powerful than a black hole?
A star that is big enough to become a black hole after its collapse will have a much stronger gravitational field than the black hole it leaves behind afterwards, as a big part of its matter will be shot out into space in the supernova explosion.
Can pulsars be magnetars?
Magnetars are a subtype of pulsars, which are neutron stars—degenerate stars that failed to become black holes but instead became extremely dense bodies composed mostly of neutrons.
What are supermassive black holes?
Supermassive Black Holes are believed to have been created by the collapse or either supermassive stars that existed at the start of the Universe or collapse of gas clouds that bypassed the stellar stage.
What is the biggest black hole in the universe?
Black hole. The supermassive black hole at the core of supergiant elliptical galaxy Messier 87, with a mass ~7 billion times the Sun’s, as depicted in the first image released by the Event Horizon Telescope (10 April 2019).
What is the most distant quasar in the universe?
As of 2017, the most distant known quasar is ULAS J1342+0928 at redshift z = 7.54; light observed from this quasar was emitted when the universe was only 690 million years old. The supermassive black hole in this quasar, estimated at 800 million solar masses, is the most distant black hole identified to date.
What is the most massive star in the universe?
The most massive star that is known is R136a1 which is in the Large Magellanic Cloud, a nearby galaxy. The star would not be massive enough to create a supermassive black hole. Before a star is born, there is a large amount of gas and dust that gradually clumps together and turns into a star.
