... A Bubbling Galaxy Center . ... Close inspection of the center of NGC 4438 , as visible in this recently released representative-color image by the Hubble Space Telescope , reveals an unusual bubble of hot gas, colored in red. Astronomers speculate that this strange bubble was created by a massive central black hole that resides there. ... Publications with keywords: black hole - galaxy center - hot gas .

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. ... In the Center of 30 Doradus . ... Explanation: In the center of 30 Doradus lies a huge cluster of the largest, hottest, most massive stars known. The center of this cluster, known as R136 , is boxed in the upper right portion of the above picture. ... 30 Doradus and R136 lie in the LMC - a satellite galaxy to our own Milky Way Galaxy . ...

In 1974 astronomers discovered a bright radio source at the center of the Milky Way Galaxy, in the direction of the constellation Sagittarius. It was an unknown quantity then, but astronomers now know that the object is a supermassive black hole causing a maelstrom of activity at the galactic center. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

The galactic center hosts a supermassive black hole in the region known as Sagittarius A*, or Sgr A*, with a mass of about 4 million times that of our Sun. A dense torus of molecular gas and dust surrounds the galactic center and occupies the innermost 15 light-years of our galaxy. ... Part of this gas is being heated by the strong ultraviolet radiation from massive stars that closely orbit the central black hole. ...

... A lightweight stick with two balls of equal weight at its end obviously has its CG in the middle. When one ball is twice the weight of the other, the CG divides the distance between them by a ratio 1:2, in a way that makes it closer to the heavier mass ( see figure ). ... Even though the balls are separate, one can speak of their common center of gravity, on the line connecting their centers, 1/3 of the distance from the center of the heavier ball. ...

... This precise description is called the standard model of electroweak physics. ... What brings about this important difference in the mass of these "field" particles? ... The Oregon group participates in the ATLAS experiment to investigate this question. ... Since Oregon joined ATLAS early in 2006, the group has devoted its effort to the process of selection of interesting events generated by the collisions of high energy particles within the ATLAS detector. ...

Astronomers have found a radio pulsar with a companion at least 11 times the mass of the Sun - the most massive pulsar companion known. The identity of the companion is uncertain: it may be a massive late-type (red) star, a massive but compact blue star, or possibly a black hole. ... The probability of this late-type star being there by chance, and not being the pulsar companion, is only about 1.3%," says team member Dr. Fernando Camilo of Columbia University. ... So what can the companion be? ...
