Mysterious mystery of supermassive black holes

In the vast garden of the universe, the heaviest black holes grew from seeds. These seeds, nourished by the gas and dust they consume, or by the fusion with other dense objects, grew in size and weight, forming the centers of galaxies, such as our own Milky Way. But unlike plants, the seeds of the huge black holes must have …

"Galaxy Dragons" – The All-Consuming Supermassive Black Holes in the Center of Quasars

"The supermassive black hole in the center of the quasar gobbles up an anonymous amount of nearby materials, which glare and shine when they constitute an accretion disk before finally sliding down the black hole," said Hongyan Zhou, faculty member at the University of Science and Technology of China about the universe's brightest beacons; shining with magnitudes more luminosity than …

Mysterious light around a supermassive black hole in the middle of our galaxy (Video)

Tech 16:44 17.08.2019 Get Short URL The supermassive Black Hole, known as "Sagittarius A *" (or Sgr A *), has been watched by scientists for years. Although this space giant was relatively quiet for a black hole, everything has changed lately, emitting an unprecedented amount of radiation. An astronomer from the University of California, Los Angeles (UCLA) has shared a …

These bizarre objects may have "supersaturated" supermassive black holes

Dark Stars Astronomers have set up a new theory for the formation of supermassive black holes. Extremely bright objects that appeared shortly before the birth of the universe – theoretical objects that are referred to as "dark stars" – could have seeded supermassive black holes over millions of years, according to a new astronomy story about physicist Katherine Freese of …

Where do supermassive black holes come from?

Astronomers have a pretty good idea of ​​how most black holes form: a massive star dies, and when it passes a supernova, the remaining mass collapses (if there's enough of it) under the force of its own Gravity and leaves it behind a black hole that lies between five times and 50 times the mass of our sun. What does …

"Something completely unexpected" – Mysterious disc that encircles the supermassive black hole

"We've seen something completely unexpected," said astronomers, who found NASA's Hubble Space Telescope a mysterious thin disk of material that furiously revolved around a supermassive black hole in the heart of a magnificent spiral galaxy NGC 3147 is located about 130 million light-years from Earth. The riddle, the researchers say, is that the disc should not be present according to …

Are these supermassive black holes on a collision course?

Meanwhile, the fusion of black holes and the gravitational waves they produce is a scientific certainty. Astronomers have observed several black holes merging, all between star-mass black holes that are less than 100 times the mass of our Sun. But merges between supermassive black holes millions of or billion times the size of our star have never been seen. And …

NASA's Hubble telescope detects a supermassive black hole that defies theoretical models

NASA's Hubble Telescope has recently discovered a supermassive black hole that contradicts existing theories about the universe, a report said. The black hole, which is about 250 million times heavier than the Sun, lies at the heart of the spiral galaxy NGC 3147 and is 140 million light-years from Earth. The Hubble telescope has discovered, according to new findings, a …

Two Supermassive Black Holes Are On A Devastating Crash Course

Collision Course Two supermassive black holes, each of them more than a million times lighter than our sun. Thankfully, the two black holes are both about 2.5 billion light-years The Astrophysical Journal Letters on Wednesday, so it will take long for astronomers to detect the cosmic waves given off by the collision. When the black holes reach the final days …
