 | A new Hubble Space Telescope image centers on the 100-million-solar-mass black hole at the hub of the neighboring spiral galaxy M31, or the Andromeda galaxy, the only galaxy outside the Milky Way visible to the naked eye and the only other giant galaxy in the local group. ...> Full Article |
 | The VLT Survey Telescope has captured the beauty of the nearby spiral galaxy NGC 253. The new portrait is probably the most detailed wide-field view of this object and its surroundings ever taken. It demonstrates that the VST, the newest telescope at ESO's Paranal Observatory, provides broad views of the sky while also offering impressive image sharpness. ...> Full Article |
 | The signature spiral arms of the Milky Way galaxy were likely formed by an epic collision between the Milky Way and the Sagittarius Dwarf galaxy, according to a University of Pittsburgh researcher and his collaborators, published today in the prestigious British journal Nature. ...> Full Article |
 | This new picture from ESO's Very Large Telescope shows NGC 3521, a spiral galaxy located about 35 million light years away in the constellation of Leo (the Lion). Spanning about 50,000 light-years, this spectacular object has a bright and compact nucleus, surrounded by richly detailed spiral structure. ...> Full Article |
 | This image of NGC 247, taken by the Wide Field Imager on the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile, reveals the fine details of this highly inclined spiral galaxy and its rich backdrop. Astronomers say this highly tilted orientation, when viewed from Earth, explains why the distance to this prominent galaxy was previously overestimated. ...> Full Article |
 | The bright galaxy NGC 3621, captured here using the Wide Field Imager on the 2.2-meter telescope at ESO's La Silla Observatory in Chile, appears to be a fine example of a classical spiral. But it is in fact rather unusual: it does not have a central bulge and is therefore described as a pure-disc galaxy. ...> Full Article |
 | A new image taken with the powerful HAWK-I camera on ESO's Very Large Telescope at Paranal Observatory in Chile shows the beautiful barred spiral galaxy NGC 1365 in infrared light. NGC 1365 is a member of the Fornax cluster of galaxies, and lies about 60 million light-years from Earth. ...> Full Article |
 | ESO has released a spectacular new image of NGC 300, a spiral galaxy similar to the Milky Way, and located in the nearby Sculptor Group of galaxies. Taken with the Wide Field Imager at ESO's La Silla Observatory in Chile, this 50-hour exposure reveals the structure of the galaxy in exquisite detail. NGC 300 lies about six million light-years away and appears to be about two thirds the size of the full moon on the sky. ...> Full Article |
 | Hubble has snapped a spectacular view of the largest "player" in the Leo Triplet, a galaxy with an unusual anatomy: it displays asymmetric spiral arms and an apparently displaced core. The peculiar anatomy is most likely caused by the gravitational pull of the other two members of the trio. ...> Full Article |
 | Using data from the NASA/ESA Hubble Space Telescope, astronomers have created a demographic census of galaxy types and shapes from a time before the Earth and the sun existed, to the present day. The results show that more than half of the present-day spiral galaxies had peculiar shapes only six billion years ago, which, if confirmed, highlights the importance of collisions and mergers in the recent past of many galaxies. It also provides clues for the unique status of our own galaxy. ...> Full Article |
 | Just as many people are surprised to find themselves packing on unexplained weight around the middle, astronomers find the evolution of bulges in the centers of spiral galaxies puzzling. A recent NASA/ESA Hubble Space Telescope image of NGC 4710 is part of a survey that astronomers have conducted to learn more about the formation of bulges, which are a substantial component of most spiral galaxies. ...> Full Article |
 | Herschel opened its "eyes" on June 14 and the Photoconductor Array Camera and Spectrometer obtained images of M51, "the whirlpool galaxy" for a first test observation. Scientists obtained images in three colors from the observation, which clearly demonstrate the superiority of Herschel, the largest infrared space telescope ever flown. ...> Full Article |
 | Astronomers have a new insight into the active galaxy Centaurus A, 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 telescope in Chile, which is operated by ESO, have been combined with visible and X-ray wavelengths to produce this striking new image. ...> Full Article |
 | Thanks to the Very Large Telescope's acute and powerful near-infrared eye, astronomers have uncovered a host of new young, massive and dusty stellar nurseries in nearby galaxy NGC 253. The centre of this galaxy appears to harbor a twin of our own Milky Way's supermassive black hole. ...> Full Article |
Martin Pohl, an Iowa State University associate professor of physics and astronomy, is part of a research team that developed the first complete map of the Milky Way galaxy's spiral arms. The map shows two prominent, symmetric spiral arms in the inner part of the galaxy. The arms extend into the outer galaxy where they branch into four spiral arms.

 | 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 |
 | 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 |
 | Astronomers at Rutgers and Penn State universities have discovered galaxies in the distant universe that are ancestors of spiral galaxies like our Milky Way. ...> Full Article |
 | 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 |
