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. ...

... January 8, 2007 . ... SENTINEL CORRESPONDENT . Astronomers at UC Santa Cruz have discovered a surprisingly massive halo of bright, old stars around our galactic neighbor Andromeda, pushing the outer limits of the galaxy to 1.5 million light years, and teaching them how spiral galaxies behave. ... Younger stars may be remnants of a galaxy devoured, but older stars could have formed with the birth of the galaxy. ... http://www.santacruzsentinel.com/archive/2007/January/08/local/stories/03local.htm . ...

... Two new LBV stars have been discovered in the Andromeda Galaxy. ... In Figure 1 the spectral energy distributions for six stars are shown: upper row - the newly discovered LBV stars, middle row - two well-known LBV stars Var A-1 and AE And, the lower row - two new B[e]-supergiant stars in Andromeda. ... Infrared spectra of the stars in the Andromeda Galaxy: two classical LBVs Var A-1 and AE And, two new LBVs J004526.62 and J004051.59, and two new B[e]-supergiants J004417.10 and J004444.52. ...

... Centaurus A : 15,000,000 light years away, in the constellation Centaurus, the closest AG to Earth . ... Astronomers think that the reason for the unusual shape of this galaxy is because hundreds of millions of years ago two galaxies, one dusty spiral and one bright ellipictal, collided causing a massive black hole in the middle and bright emmision of light. ... Andromeda galaxy: 2.8 million light years away, closest spiral galaxy to earth, farthest object one can see without a telescope. ...

... This represents the first HI selected sample covering the core and the outskirts of a local cluster of galaxies. ... Optically selected samples miss a considerable number of low luminosity, low surface brightness galaxies underestimating by almost a factor 2 the number of HI rich galaxies present in the cluster volume. ... Right: The g band luminosity function for galaxies in the A1367 volume as obtained from the optically (circles) and HI (histogram) selected sample. ...

... 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. ...

... We report on the preliminary results of experiments using a Bayesian cluster method to cluster objects present in photographic images of the POSS-II. ... We believe that the application of such algorithms to large-scale astronomical sky surveys can aid in cataloging the detected objects, and may even have the potential to discover new categories of objects. ... We have thus started to explore new clustering analysis and unsupervised classification techniques for this task. ...
