... Astronomy news . ... NASA's Spitzer Images Out-of-This-World Galaxy . ... It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white. ... The ring around the black hole is bursting with new star formation. ...

... STScI-PRC98-21 A BRIGHT RING OF STAR BIRTH AROUND A GALAXY'S CORE An image from NASA's Hubble Space Telescope reveals clusters of infant stars that formed in a ring around the core of the barred-spiral galaxy NGC 4314. ... This close-up view by Hubble also shows other interesting details in the galaxy's core: dust lanes, a smaller bar of stars, dust and gas embedded in the stellar ring, and an extra pair of spiral arms packed with young stars. ... However, they are older than those in the ring. ...

... Animation of the neutral hydrogen data cube from Westerbork. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Have you ever looked at pictures of Saturn's rings and noticed what look like gaps in the rings? ... Gian Domenico Cassini discovered a large gap in Saturn's rings in 1675. Later, an astronomer named Encke discovered a smaller gap near the edge of the rings. ... It was found long ago that an orbit in the Cassini Division, as the large gap is named, has a period almost exactly one-half that of one of Saturn's moons named Mimas. ... 2008 Phil Plait. ...

We explore variations in dust emission within the edge-on Sd spiral galaxy NGC 4631 using 3.6-160 ЮМm Spitzer Space Telescope data and 450-850 ЮМm JCMT data with the goals of understanding the relation between PAHs and dust emission, studying the variations in the colors of the dust emission, and searching for possible excess submillimeter emission compared to what is expected from dust models extrapolated from far-infrared wavelengths. ...

... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...

... Running Rings Around a Planet . ... Saturn's delicate rings have caught human eyes for over three centuries. ... Now we know, thanks to the Voyager space probes, that Saturn's rings consist of thousands of "ringlets," each made of chunks of ice ranging in size from dust to boulders [see "Rally Around the Ring," March/April 1995, p. 10]. ... The appearance of Saturn's rings to us ground-hugging Terrans is changing constantly. ... Saturn's diameter is 120,000 kilometers, so how large are the rings? ...

... Resolved Stellar Populations Globular Clusters . Galaxies are made of stars, gas and the illusive dark matter. ... Star clusters are the simplest form of the stellar population. ... Old globular clusters are easily observed at great distances and can be used as probes of the early stages of star formation history in galaxies where individual stars cannot be resolved. My research interests are centered on the studies of resolved stellar populations and (old) star clusters in nearby galaxies. ...

New polar ring galaxies catalogue. ... A host galaxy like S0 or E, the polar component is like spirals or irregular galaxies ( gas -rich and bluer) Not only narrow annuli, but also extended disc-like rings Warped and inclined rings Only 20 large-scale polar rings + 6 inner rings were kinematically confirmed from the Whitmore et al. list: - HI maps (Cox et al; Sparke et al. ) - optical-long slit spectroscopy (Reshetnikov et al) - optical ...
