Even Thin Galaxies Can Grow Fat Black Holes (1/18/2008)

NASA's Spitzer Space Telescope has detected plump black holes where least expected -- skinny galaxies. Like people, galaxies come in different shapes and sizes. There are thin spirals both with and without central bulges of stars, and more rotund ellipticals that are themselves like giant bulges. Scientists have long held that all galaxies except the slender, bulgeless spirals harbor supermassive black holes at their cores. Furthermore, bulges were thought to be required for black holes to grow. ...> Full Article

Astronomers on Team Describing New Evidence of 'Inconvenient' Galaxy (1/10/2008)

Discovery of two new components within a puzzling spiral galaxy confirm it must have a pair of arms winding in the opposite direction from most galaxies, according to results being presented today to the American Astronomical Society meeting in Austin, Texas. Presenting the results are Drs. Gene Byrd and Ron Buta, from The University of Alabama; Tarsh Freeman, Bevill Community College; and Dr. Sethanne Howard, retired from the U.S. Naval Observatory. ...> Full Article

Anatomy of a Bird (12/26/2007)

Using ESO's Very Large Telescope, an international team of astronomers has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed 'The Bird' - albeit it also bears resemblance with a cosmic Tinker Bell - is composed of two massive spiral galaxies and a third irregular galaxy. ...> Full Article
