Multiwavelength M81
| Title |
Multiwavelength M81 |
| Description |
This beautiful galaxy is tilted at an oblique angle on to our line of sight, giving a "birds-eye view" of the spiral structure. The galaxy is similar to our Milky Way, but our favorable view provides a better picture of the typical architecture of spiral galaxies. M81 may be undergoing a surge of star formation along the spiral arms due to a close encounter it may have had with its nearby spiral galaxy NGC 3077 and a nearby starburst galaxy (M82) about 300 million years ago. M81 is one of the brightest galaxies that can be seen from the Earth. It is high in the northern sky in the circumpolar constellation Ursa Major, the Great Bear. At an apparent magnitude of 6.8 it is just at the limit of naked-eye visibility. The galaxy's angular size is about the same as that of the Full Moon. This image combines data from the Hubble Space Telescope, the Spitzer Space Telescope, and the Galaxy Evolution Explorer (GALEX) missions. The GALEX ultraviolet data were from the far-UV portion of the spectrum (135 to 175 nanometers). The Spitzer infrared data were taken with the IRAC 4 detector (8 microns). The Hubble data were taken at the blue portion of the spectrum. |

| Title |
The Sombrero Galaxy in Infrared |
| Explanation |
This floating ring is the size of a galaxy. In fact, it is part of the photogenic Sombrero Galaxy [ http://www.seds.org/messier/m/m104.html ], one of the largest galaxies in the nearby Virgo Cluster of Galaxies [ http://antwrp.gsfc.nasa.gov/apod/ap050213.html ]. The dark band of dust [ http://antwrp.gsfc.nasa.gov/apod/ap030706.html ] that obscures the mid-section of the Sombrero Galaxy [ http://en.wikipedia.org/wiki/Sombrero_galaxy ] in optical light actually glows brightly in infrared light. The above image [ http://www.spitzer.caltech.edu/Media/releases/ssc2005-11/release.shtml ] shows the infrared [ http://imagers.gsfc.nasa.gov/ems/infrared.html ] glow, recently recorded by the orbiting Spitzer Space Telescope [ http://www.spitzer.caltech.edu/about/index.shtml ], superposed in false-color on an existing [ http://antwrp.gsfc.nasa.gov/apod/ap031008.html ] image taken by NASA's Hubble Space Telescope [ http://antwrp.gsfc.nasa.gov/apod/ap021124.html ] in optical light. The Sombrero [ http://en.wikipedia.org/wiki/Sombrero ] Galaxy, also known as M104, spans about 50,000 light years [ http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question19.html ] across and lies 28 million light years away. M104 can be seen with a small telescope in the direction of the constellation Virgo [ http://www.seds.org/Maps/Stars_en/Fig/ virgo.html ]. |

| Title |
A Hidden, Massive Star Cluster Awash with Red Supergiants |
| Description |
The sky is a jewelry box full of sparkling stars in these infrared images. The crown jewels are 14 massive stars on the verge of exploding as supernovae. These hefty stars reside in one of the most massive star clusters in the Milky Way Galaxy. The bluish cluster is inside the white box in the large image, which shows the star-studded region around it. A close-up of the cluster can be seen in the inset photo. These large stars are a tip-off to the mass of the young cluster. Astronomers estimate that the cluster is at least 20,000 times as massive as the Sun. Each red supergiant is about 20 times the Sun's mass. The larger color-composite image was taken by the Spitzer Space Telescope for the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) Legacy project. The survey penetrates obscuring dust along the thick disk of our galaxy to reveal never-before-seen stars and star clusters. The false colors in the image correspond to infrared-light emission. The stars in the large color-composite image all appear blue because they emit most of their infrared light at shorter wavelengths. The inset image, a false-color composite, was captured by the Two Micron All Sky Survey (2MASS). Astronomers identified the cluster as a potential behemoth after spotting it in the 2MASS catalogue. They then used the Infrared Multi-object Spectrograph at the Kitt Peak National Observatory in Arizona to analyze the cluster's colors. From that analysis, they discovered the red supergiants. They confirmed the red supergiants' pedigree by studying the colors of other red supergiants in data taken by the Spitzer Space Telescope. The cluster lies 18,900 light-years away in the direction of the constellation Scutum. It is the first in a survey of 130 potentially massive star clusters in the Milky Way that astronomers will study over the next five years using a variety of telescopes, including the Spitzer and Hubble space telescopes. The Spitzer image was taken April 4, 2004, the 2MASS image on July 4, 1999. The science team that studied the star cluster consists of Don Figer, Space Telescope Science Institute/Rochester Institute of Techology, John MacKenty, Massimo Robberto, and Kester Smith, Space Telescope Science Institute, Francisco Najarro, Instituto de Estructura de la Materia in Madrid, Spain: Rolf Kudritzki, University of Hawaii in Honolulu, and Artemio Herrero, Universidad de La Laguna in Tenerife, Spain. |

Mystery Solved: High-Energy Fireworks Linked to Massive Star Cluster |
| General Information |
What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. Call it the Bermuda Triangle of our Milky Way Galaxy: a tiny patch of sky that has been known for years to be the source of the mysterious blasts of X-rays and gamma rays. Now, a team of astronomers, led by Don Figer of the Space Telescope Science Institute in Baltimore, Md., has solved the mystery by identifying one of the most massive star clusters in the galaxy. The little-known cluster, which has not been catalogued, is about 20 times more massive than typical star clusters in our galaxy, and appears to be the source of the powerful outbursts. Supporting evidence for the hefty weight of this cluster is the presence of 14 red supergiants, hefty stars that have reached the end of their lives. They bloat up to about 100 times their normal size before exploding as supernovae. This image shows the star-studded region surrounding the massive star cluster. The bluish cluster is inside the white box. A close-up of the cluster can be seen in the inset photo. Read more: * The Full Story [ http://hubblesite.org/newscenter/archive/releases/2006/03/full/ ] |
