Although not even a single galaxy has yet been proven to have a central black hole , the list of candidates has increased yet again. ... In all the galaxies studied, star speeds continue to increase closer the very center .

Shown above is a time-lapse movie in infrared light detailing how stars in the central light-year of our Galaxy have moved over the past eight years. ... If these fast stars are held to the Galactic Center by gravity, then the central object exerting this gravity must be both compact and massive. ... About APOD | ...

... 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. ...

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. ...

... SPACE.com) -- Streams of glittering stellar gems on the outer edges of Andromeda are remnants of an ancient galactic collision that helped shape the spiral galaxy. Astronomers using the DEIMOS spectrograph on the Keck II Telescope in Hawaii determined this by surveying Andromeda, our galaxy's nearest large galactic neighbor, and discovered a trail of stars which they believe were part of a different galaxy that merged with Andromeda some 700 million years ago. ...

... Astronomy news . ... NASA's Spitzer Images Out-of-This-World Galaxy . ... It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white. ... The ring around the black hole is bursting with new star formation. ...

... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...
