Latest Centaurus A Stories
A flare-up in a jet of matter blasting from a monster black hole is giving astronomers an incredible light show.
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.
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.
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.
New observations with the Submillimeter Array now suggest that 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.
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.
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.
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.
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...
