The doughnut-shaped rings surrounding many supermassive black holes tell researchers how fast extraterrestrial objects are feeding and could change how black holes are viewed from Earth. Credits: ESA/NASA, AVO project and Paolo Padovani The researchers used X-ray telescopes and new data analysis techniques to describe extraterrestrial objects. Black holes with different light signatures that were once thought to be the same object viewed from different angles are actually in different stages of their life cycle, according to a study led by Dartmouth scientists. New research on black holes known as “active galactic nuclei,” or AGNs, says that it definitively demonstrates the need to revise the widely used “AGN unified model” that characterizes supermassive black holes because they all share the same properties. This study provides an answer to a troubling space mystery and should allow researchers to create more precise models of the evolution of the universe and how black holes develo

One of the most extreme stars in the Milky Way has just gotten even weirder. Scientists have measured the mass of a neutron star named PSR J0952-0607, and found that it is the most massive neutron star ever discovered, registering 2.35 times the mass of the Sun. If true, this is very close to the theorized upper mass limit of about 2.3 solar masses for neutron stars, which is an excellent laboratory for studying these ultra-dense stars at what we think are on the verge of collapse, in hopes of better understanding. strange quantum states of the matter they are made of. “We know roughly how matter behaves at nuclear densities, such as in the nuclei of uranium atoms,” said astrophysicist Alex Filippenko of the University of California, Berkeley. “A neutron star is like one giant core, but when you have one and a half solar masses of this material, which is about 500,000 Earth masses of cores all stuck together, it’s not at all clear how they’re going to behave.” Neutron stars are the col

Calçada, CC BY There is always something new and exciting going on in the field of black hole research. Albert Einstein first published his book explaining the general theory of relativity—which postulates black holes—in 1922. One hundred years later, astronomers captured the true image of the black hole at the center of the Milky Way. In a recent paper, a team of astronomers describes another exciting new discovery: the first “dormant” black hole observed outside a galaxy. I am an astrophysicist who has studied black holes—the densest objects in the universe—for nearly two decades. An inactive black hole is a black hole that does not emit detectable light. Because of this, they are notoriously hard to find. This new discovery is exciting because it provides insight into the formation and evolution of

A rotating neutron star periodically swings radio rays (green) and gamma rays (magenta) past Earth in this artist’s concept of a black widow pulsar. The pulsar heats the side of its stellar mate that faces twice as hot as the sun’s surface and slowly vaporizes it.

A collapsing solid star has torn apart and consumed almost the entire mass of its companion star and, in the process, grew into the heaviest star. neutron star A neutron star is the collapsing core of a large star (between 10 and 29 solar masses). Neutron stars are the smallest and densest stars that have ever existed. Although neutron stars typically have a radius of only 10 – 20 kilometers (6 – 12 miles), they can have a mass of about 1.3 – 2.5 the mass of the Sun. ” data-gt-translate-attributes=”[{” attribute=””>neutron star observed to date.

Origin of ‘ghost particles’ DISCOVERED: Tiny bodies that pass through our body and planet undetected emitted from galactic cores fed by supermassive black holes in outer space ‘Ghost particles,’ or neutrinos, are particles that originate from outer space These particles have no mass and hardly interact with matter Scientists believe they came from the core of a galaxy that was fed by a supermassive black hole Blazars are known for emitting bright beams of light and wind and are thought to also produce cosmic rays By Stacy Liberatore For Dailymail.com Published: 2:04pm EDT, July 25, 2022 | Updated: 2:18 p.m. EDT, 25 July 2022 Extraterrestrial ‘ghost particles’ likely originate from the cores of galaxies fed by supermassive black holes, according to a new study that could unravel the mystery of subatomic particles that formed before the universe. Ghost particles, or neutrinos, have baffled scientists since they were firs

With this unprecedented measurement, published recently in Natural Astronomy , they found that the bursts significantly changed the internal and external pressures of the molecular cloud in its path. Depending on which of the two pressures changes the most, both cloud compression and star formation triggers and cloud dissipation and star formation delays are possible in the same galaxy. “Our results suggest that supermassive black holes, even though they are located at the center of galaxies, can influence star formation across galaxies” said Professor Dasyra, adding that “studying the impact of

An artist’s impression shows what the binary star system VFTS 243－ looks like, which contains a black hole and a large glowing star orbiting each other. ESO / L. Calcada / Handout via REUTERS WASHINGTON－Astronomers have spotted in a galaxy adjacent to the Milky Way what they call a cosmic “needle in a haystack”－a black hole that is not only classified as dormant, but also appears to have been born without a stellar death explosion. Researchers said Monday this one differs from all other known black holes in that it is “quiet X-ray”—it doesn’t emit strong X-ray radiation that indicates it devours nearby matter with a strong gravitational pull—and that it doesn’t. born in the explosion of a star called a supernova. Black holes are extremely dense objects with such strong gravity that not even light can escape.

Astronomers have seen in the galaxy adjacent to our Milky Way what they call the cosmic “needle in the haystack” – a black hole that is not only classified as dormant but appears to have been born without the explosion of a dying star. Researchers said Monday this one differs from all other known black holes in that it is “quiet X-ray” – it doesn’t emit the intense X-ray radiation that indicates it devours nearby matter with a strong gravitational pull – and it doesn’t. born in the explosion of a star called a supernova. Black holes are extremely dense objects with such strong gravity that even light cannot escape. This one, with a mass at least nine times that of our sun, was detected in the Tarantula Nebula region of the Great Magellanic Cloud galaxy and is located about 160,000 light-years from Earth. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). A very luminous and hot blue star with a mass about 25 times that of the sun orbits this bl

Former All Blacks coach Alex Wyllie and former test captain Ian Kirkpatrick believe Joe Schmidt should definitely have a direct role for the Rugby Championship. Schmidt will replace Grant Fox on the selection panel, but Wyllie and Kirkpatrick think it makes sense for the former Ireland coach to be actively involved in training. Wyllie, who coached the All Blacks from 1988 to 1991, believes that replacing Ian Foster as head coach at this stage could potentially destabilize the opening test of the Rugby Championship looming in South Africa in early August. “The change of coach now probably won’t happen at this stage,” he said. “If there is a new coach, does he want to choose new players? All it will do is create more uncertainty [for the players].” READ MORE: * Head-to-head: Scott Robertson’s record as a head coach is better than Ian Foster *All black people need Wayne Smith, Scott Robertson and Leon MacDonald, says former NZ Rugby boss * Irish prop Andrew Porter cited fo

Kim Kardashian showed off her enviable figure in a black sequined Balenciaga dress at an afterparty with her longtime friend Fai Khadra on Monday. In a series of new black and white photos, which were uploaded to her Instagram, the 41-year-old reality star looked glamorous in a long dress that showed off her hourglass curves. Standing at the bottom of the picturesque staircase, the mother-of-four smiled and shot a peace sign into the camera before taking the phone call. Glamor: Kim Kardashian flaunted her enviable figure in a black sequined Balenciaga dress at an after-party with longtime friend Fai Khadra on Monday For the occasion, she let her platinum blonde locks fall onto her shoulders and put on a full face mask cover. Her post came after flying to Australia for a romantic reunion with boyfriend Pete Davidson, who was shooting a new film in Queensland. “It’s been a short visit but he’s really excited to go,” a source told DailyMail.com exclusively.
