Supersized stellar blackhole prompts model rewrite

Boffins go back to the drawing board Researchers have located the most massive stellar black hole ever discovered, just three million light-years away in a nearby galaxy. The stellar remnant is in a binary system known as M33, orbiting a huge companion star. The researchers say the find is "intriguing", because of what it suggests about stellar evolution.â¦

The Spitzer and Hubble Space Telescopes each have found dusty disks around sun-like stars. Finding such rings of dusty debris around stars the size of the sun is difficult, because they are fainter and harder

SAN DIEGO - For decades, astronomers have sought to pin down a source for ultra high-energy cosmic rays. The distant sources must be among the more powerful events in the universe, perhaps the creation of black holes or the mergers of galaxies.

Observing the image of a faint object that lies close to a star is a demanding task as the object is generally hidden in the glare of the star. Characterising this object, by taking spectra, is an even harder challenge.

This is the second article in a series of four articles each with a separate explanation of different quantum phenomena. Each article is a piece of a mosaic, so every one is needed to understand the final explanation of the quantum astronomy experiment we propose, possibly using the Allen Array Telescope and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.

Cambridge, MA -- Astronomers are hunting an elusive target: rogue black holes that have been ejected from the centers of their home galaxies. Some doubted that the quarry could be spotted, since a black hole must be gobbling matter from an accretion disk in order for that matter to shine.

The energy created when black holes merge contributes to star formation while&nbsp;blowing gas to the outskirts of a galaxy, this creates&nbsp;a limit as to how much the black hole can consume, a new computer simulation shows.
