NGC 4945: The Milky Way's not-so-distant Cousin ESO has released a striking new image of a nearby galaxy that many astronomers think closely resembles our own Milky Way. Though the galaxy is seen edge-on, observations of NGC 4945 suggest that this hive of stars is a spiral galaxy much like our own, wi...

Astronomers have spotted the most distant object yet confirmed in the universe a self-destructing star that exploded 13.1 billion light years from Earth. It detonated just 640 million years after the big bang, around the end of the cosmic "dark ages", when the first stars and galaxies w...

A pair of supermassive black holes in orbit around one another have been spotted by XMM-Newton. This is the first time such a pair have been seen in an ordinary galaxy. They were discovered because they ripped apart a star when the space observatory happened to be looking in their direction. Read more...

In a paper entitled "Double Nucleus in M83" published on May 13, 2005, astronomers Damián Mast, Ruben Diaz, and Paz Aguero of Córdoba's National University and the Astronomical Observatory of Cordoba have confirmed "the presence of a secondary nucleus or mass concentration" fir...

A spectacular new image of an unusual spiral galaxy in the Coma Galaxy Cluster has been created from data taken by the Advanced Camera for Surveys on the NASA/ESA Hubble Space Telescope. It reveals fine details of the galaxy, NGC 4921, as well as an extraordinary rich background of more remote galaxi...

A team led by a Yale University astronomer has discovered the least luminous, most dark matter-filled galaxy known to exist. The galaxy, called Segue 1, is one of about two dozen small satellite galaxies orbiting our own Milky Way galaxy. The ultra-faint galaxy is a billion times less bright than th...

Title: The Parsec-scale Accretion Disk in NGC 3393 Authors: Paul T. Kondratko, Lincoln J. Greenhill, James M. Moran We present a Very Long Baseline Interferometry image of the water maser emission in the nuclear region of NGC3393. The maser emission has a linear distribution oriented at a positio...

What do you call an absence of darkness? Dark matter is supposed to be spread throughout the universe, but a new study reports a spiral galaxy that seems to be empty of the stuff, and astrophysicists cannot easily explain why. In the outer regions of most galaxies, stars orbit around the centre so fast...

Baffling boxy bulge Just as many people are surprised to find themselves packing on unexplained weight around the middle, astronomers find the evolution of bulges in the centres of spiral galaxies puzzling. A recent NASA/ESA Hubble Space Telescope image of NGC 4710 is part of a survey that astrono...
