Astronomers discovered the most massive neutron star | what are black holes |


Astronomers have discovered the heaviest star in the universe, believed to be more than twice the weight of the Sun Astronomers have discovered the heaviest star in the universe, believed to be more than twice the weight of the Sun Located approximately 4,600 light-years away and 330,000 times larger than Earth, the neutron star was formed from the remains of a supernova when a giant star collapses Located approximately 4,600 light-years away and 330,000 times larger than Earth, the neutron star was formed from the remains of a supernova when a giant star collapses Located approximately 4,600 light-years away and 330,000 times larger than Earth, the neutron star was formed from the remains of a supernova when a giant star collapses Located approximately 4,600 light-years away and 330,000 times larger than Earth, the neutron star was formed from the remains of a supernova when a giant star collapses All stars do not become black holes when they reach the end of their lives All stars do not become black holes when they reach the end of their lives Sometimes, when the core of a massive star collapses, the remains are densely packed Sometimes, when the core of a massive star collapses, the remains are densely packed The force of its gravity crushes protons and electrons together, forms neutrons, and transforms the mass into a ‘neutron star’ The force of its gravity crushes protons and electrons together, forms neutrons, and transforms the mass into a ‘neutron star’ The force of its gravity crushes protons and electrons together, forms neutrons, and transforms the mass into a ‘neutron star’ The force of its gravity crushes protons and electrons together, forms neutrons, and transforms the mass into a ‘neutron star’ Astronomers still don’t know much about neutron stars Astronomers still don’t know much about neutron stars but recently a team of researchers with the NANOGrav Physics Frontiers Center reported on a discovery but recently a team of researchers with the NANOGrav Physics Frontiers Center reported on a discovery that gave mankind another step to understand these unusual creations Brought closer that gave mankind another step to understand these unusual creations Brought closer He observed the existence of the largest neutron star that scientists never found. He observed the existence of the largest neutron star that scientists never found. Typically, neutron stars are the same size as a city, and are made “so tightly packed,” according to NASA, that a sugar-cube-size material weighs more than [a billion] tons. and are made “so tightly packed,” according to NASA, that a sugar-cube-size material weighs more than [a billion] tons. and are made “so tightly packed,” according to NASA, that a sugar-cube-size material weighs more than [a billion] tons. And this newly discovered celestial body is 2.14 times the mass of the Sun And this newly discovered celestial body is 2.14 times the mass of the Sun This discovery limits how large and dense a mass can be without a black hole. This discovery limits how large and dense a mass can be without a black hole. The neutron star named J0740 + 6620 is classified as a ‘pulsar’ The neutron star named J0740 + 6620 is classified as a ‘pulsar’ This basically means that it emits a beam of radio waves from each magnetic pole like a lighthouse This basically means that it emits a beam of radio waves from each magnetic pole like a lighthouse This basically means that it emits a beam of radio waves from each magnetic pole like a lighthouse NASA said on its website, “Pulsar also rotates faster” than the kitchen blender. NASA said on its website, “Pulsar also rotates faster” than the kitchen blender. Using the Green Bank Telescope located in West Virginia the team of researchers observed both a white dwarf star and a neutron star By measuring the white dwarf – a dead star’s low-density corpse – and the neutron star interacting with each other, the team can measure the size of the neutron star. interacting with each other, the team can measure the size of the neutron star. According to Albert Einstein’s general relativity theory the gravity around the dwarf star is slightly distorted as these masses orbit each other the gravity around the dwarf star is slightly distorted as these masses orbit each other It replaces the pulses emitted by J0740 + 6620 It replaces the pulses emitted by J0740 + 6620 it is named after astrophysicist Harvard University professor Irwin Shapiro “Shapiro Delay” phenomenon it is named after astrophysicist Harvard University professor Irwin Shapiro “Shapiro Delay” phenomenon it is named after astrophysicist Harvard University professor Irwin Shapiro “Shapiro Delay” phenomenon The team was able to use the converted pulses to estimate the size of the white dwarf The team was able to use the converted pulses to estimate the size of the white dwarf and then use that measurement to calculate the mass of the giant neutron star. and then use that measurement to calculate the mass of the giant neutron star. The discovery of the largest neutron star known to mankind is no small feat Dense masses such as J0740 + 6620 can help scientists understand how massive neutron stars can be before gravity moves forward and becomes a black hole. how massive neutron stars can be before gravity moves forward and becomes a black hole. “Neutron stars have this tipping point, where their internal densities become so extreme that the force of gravity stops the neutron’s ability to collapse further that the force of gravity stops the neutron’s ability to collapse further explained Science Daily’s study co-author Astronomer Scott Ransom explained Science Daily’s study co-author Astronomer Scott Ransom Each of the largest scale ‘neutron stars we find brings us closer to identifying that tipping point and helps to understand the physics of matter at these mindblowing densities” that tipping point and helps to understand the physics of matter at these mindblowing densities” that tipping point and helps to understand the physics of matter at these mindblowing densities”
