Recently physicists have been poking holes again in Stephen Hawking’s black hole theory – including Hawking himself. For decades physicists across the globe have been trying to figure out the mysteries of black holes – those fascinating monstrous entities that have such intense gravitational pull that nothing – not even light – can escape from them. Now Professor Chris Adami, Michigan State University, has jumped into the fray.
A team of Australian and American astronomers have been studying nearby galaxy M83 and have found a new superpowered small black hole, named MQ1, the first object of its kind to be studied in this much detail.
Enrico Ramirez-Ruiz uses computer simulations to explore the universe's most violent events, so when the first detailed observations of a star being ripped apart by a black hole were reported in 2012 (Gezari et al., Nature), he was eager to compare the data with his simulations. He was also highly skeptical of one of the published conclusions: that the disrupted star was a rare helium star.
Astronomers have used NASA's Chandra X-ray Observatory and a suite of other telescopes to reveal one of the most powerful black holes known. The black hole has created enormous structures in the hot gas surrounding it and prevented trillions of stars from forming.
A bright, long duration flare may be the first recorded event of a black hole destroying a star in a dwarf galaxy. The evidence comes from two independent studies using data from NASA’s Chandra X-ray Observatory and other telescopes.
Astronomers led by a Curtin University researcher have discovered a new population of exploding stars that “switch off” their radio transmissions before collapsing into a Black Hole.
Intelligent telescopes designed by Los Alamos National Laboratory got a front row seat recently for an unusual birth.
Astronomers have long sought strong evidence that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is producing a jet of high-energy particles. Finally they have found it, in new results from NASA's Chandra X-ray Observatory and the National Science Foundation's Very Large Array (VLA) radio telescope.
Last year when a team of astronomers led by a Michigan State University professor discovered two black holes in a collection of stars known as a globular cluster, the team wasn't sure if the black holes' presence was a common occurrence or a unique stroke of luck.
Researchers using NASA’s Chandra X-ray Observatory have found evidence that the normally dim region very close to the supermassive black hole at the center of the Milky Way Galaxy flared up with at least two luminous outbursts in the past few hundred years.
It is a mystery that has stymied astrophysicists for decades: how do black holes produce so many high-power X-rays?
A giant black hole in the center of the galaxy 4C+29.30 is generating two powerful jets of particles.
The European Space Agency's (ESA) Herschel space observatory has made detailed observations of surprisingly hot molecular gas that may be orbiting or falling towards the supermassive black hole lurking at the center of our Milky Way galaxy.
Astronomers are observing a black hole that woke up from a decades-long slumber to feed on a low-mass object - either a brown dwarf or a giant planet - that strayed too close.
For only the second time ever, astronomers have discovered a triple quasar system - possibly part of a much larger structure.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency's XMM-Newton, have together accurately measured, for the first time, the spin rate of a black hole with a mass two million times that of our sun.
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) recently spotted the brilliant glow of two black holes lurking inside spiral galaxy IC342.
Astronomers have classified a new type of galaxy after they noticed that it glowed an unusually bright green.
University of Texas astronomers have discovered the most massive black hole to date.
Astronomers at the European Southern Observatory (ESO) have identified the biggest quasar outflow, a type of high energy explosion surrounding a massive black hole, to date.
