A pair of astronomers from Texas and Germany have used a telescope at The University of Texas at Austin's McDonald Observatory together with Hubble Space Telescope and many other telescopes around the world to uncover new evidence that the largest, most massive galaxies in the universe and the supermassive black holes at their hearts grew together over time. "They evolved in lockstep," said The University of Texas at Austin's John Kormendy, who co-authored the research with Ralf Bender of...

Astronomers have a new insight into the active galaxy Centaurus A (NGC 5128), as the jets and lobes emanating from the central black hole have been imaged at submillimeter wavelengths for the first time. The new data, from the Atacama Pathfinder Experiment (APEX) telescope in Chile, which is operated by ESO, have been combined with visible and X-ray wavelengths to produce this striking new image. Centaurus A is our nearest giant galaxy, at a distance of about 13 million light-years in the...

British astronomers say cosmic dust was partially created by the gradual death of carbon stars and not just from stars that exploded. The astronomers have been watching cosmic dust form around a dying star in a nearby galaxy, similar to the primitive galaxies that formed soon after the big bang, said a release from the Science and Technology Facilities Council, which funded the study. The newly observed dust formation was found around the carbon star MAG 29, located 280,000 light years away...

Astronomers have long puzzled over why a small, nearby, isolated galaxy is pumping out new stars faster than any galaxy in our local neighborhood. Now NASA's Hubble Space Telescope has helped astronomers solve the mystery of the loner starburst galaxy, called NGC 1569, by showing that it is one and a half times farther away than astronomers thought. The extra distance places the galaxy in the middle of a group of about 10 galaxies centered on the spiral galaxy IC 342. Gravitational...

Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and galaxies were just beginning to form. The new conclusion comes from the discovery of two distant galaxies, both with black holes at their heart, which are involved in a spectacular collision. 4C60.07,...

NASA's Hubble Space Telescope has captured a rare alignment between two spiral galaxies. The outer rim of a small, foreground galaxy is silhouetted in front of a larger background galaxy. Skeletal tentacles of dust can be seen extending beyond the small galaxy's disk of starlight. Such outer dark dusty structures, which appear to be devoid of stars, like barren branches, are rarely so visible in a galaxy because there is usually nothing behind them to illuminate them. Astronomers have never...

NASA's Hubble Space Telescope has found an answer to a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example of the influence of the immense tentacles of extragalactic magnetic fields, say researchers. One of the closest giant elliptical galaxies, NGC 1275 hosts a supermassive black hole. Energetic activity of gas swirling near the black hole blows bubbles of material into the...

How do you weigh the biggest black holes in the universe? One answer now comes from a completely new and independent technique that astronomers have developed using data from NASA's Chandra X-ray Observatory. By measuring a peak in the temperature of hot gas in the center of the giant elliptical galaxy NGC 4649, scientists have determined the mass of the galaxy's supermassive black hole. The method, applied for the first time, gives results that are consistent with a traditional technique....

For decades, astronomers have been blind to what our galaxy, the Milky Way, really looks like. After all, we sit in the midst of it and can't step outside for a bird's eye view.Now, new images from NASA's Spitzer Space Telescope are shedding light on the true structure of the Milky Way, revealing that it has just two major arms of stars instead of the four it was previously thought to possess."Spitzer has provided us with a starting point for rethinking the structure of the Milky Way," said...

Millions of clustered stars glisten like an iridescent opal in a new image from NASA's Spitzer Space Telescope. Called Omega Centauri, this sparkling orb of stars is like a miniature galaxy. It is the biggest and brightest of the more than 150 similar objects, called globular clusters, that orbit around the outside of our Milky Way galaxy. Stargazers at southern latitudes can spot the stellar gem with the naked eye in the constellation Centaurus. Spitzer's new infrared view, which has been...

The Centaurus A/M83, divided into subgroup Cen A and M83, is a complex group of galaxies located within Hydra, Centaurus, and Virgo constellations. The Cen A Subgroup, at a distance of 11.9 Mly (3.66 Mpc), is centered around Centaurus A, a nearby radio galaxy. The M83 Subgroup, at a distance of 14.9 Mly (4.56 Mpc), is centered around the Messier 83 (M83), a face-on spiral galaxy. Due to the physical closeness of both subgroups they are sometimes identified as two groups sometimes as one....

Within the Hydra, Centaurus, and Virgo constellations a complex group of galaxies resides called Centaurus A/M83. There are two subgroups within Centaurus A/M83. The first is Cen A, at a distance of 11.9 Million Light Years, is centered around Centaurus A, a close by radio galaxy. The other subgroup, M83, is at a distance of 14.9 Million Light Years and is centered around the Messier 83. Since there are two subgroups Centaurus is sometimes identified as one group and sometimes two, it will be...
