Hubble Heritage Project's First Anniversary |
| General Information |
What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. To mark the first anniversary of the Hubble Heritage Project, we present four Hubble telescope images of nebulae surrounding stars in our own Milky Way Galaxy. Two of these visible-light pictures show interstellar gas and dust around young stars at the beginning of their lives, and two more show gas ejected from old stars that are nearing the end of theirs. Remarkably, in spite of the completely different evolutionary stages, the nebulae have more striking features in common, including evidence of diametrically opposed gas ejections from both the young and old stars. |

| Description |
This mysterious object that seems to defy classification was found by astronomers using NASA's Hubble Space Telescope. The object has been classified as a planetary nebula, the glowing remains of a Sun-like star in its death throes, although the Hubble observations suggest it may not fit that classification, either. A quick glance at the Hubble picture at top shows that the object, He2-90, looks like a young, dust-enshrouded star with narrow jets of material resembling strings of beads streaming from each side. The other light streaks running diagonally from He2-90 are artificial effects of the telescope's optical system. Each jet possesses at least six bright clumps of gas speeding along at rates estimated to be at least 600,000 kilometers an hour (375,000 miles an hour). These gaseous clumps are ejected into space about every 100 years and may be caused by periodic instabilities in He2-90's accretion disk. Jets from very young stars behave in a similar way. Deep images taken from a terrestrial observatory show each jet extending at least 100,000 astronomical units (one astronomical unit equals the Earth-Sun distance, 150 million kilometers or 93 million miles). The Hubble astronomers, Dr. Raghvendra Sahai of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and Lars-Ake Nyman of the European Southern Observatory, Chile, and Onsala Space Observatory, Sweden, suspect that He2-9 is a pair of aging stars masquerading as a single youngster. One member of the duo is a bloated red giant star shedding matter from its outer layers. This matter is then captured by gravity in a rotating accretion disk around a compact partner, most likely a young white dwarf (the collapsed remnant of a Sun-like star). The stars are not visible in the Hubble images because they're obscured by a disk of dust. The jets' relatively modest speed implies that one member of the duo is a white dwarf. An accretion disk needs gravity to form. For gravity to create He2-90's disk, the two stars must reside at a cozy distance from each other: within about 10 astronomical units. Astronomers are uncertain about the details, but they believe that magnetic fields associated with accretion disks produce and constrict the pencil-thin jets seen in the Hubble image. The close-up Hubble photo at bottom shows a dark, flaring, disk-like structure (off-center) bisecting the bright light from the object. The disk is seen edge-on. Although this disk is too large to be an accretion disk, it may provide indirect proof of the disk's existence. Most theories for producing jets require the presence of an accretion disk. The round, white objects at the lower left and upper right corners are two bright clumps of gas in the jets, which are close to the companion star. The astronomers traced the jets to within 1,000 astronomical units of the central obscured star. The star ejected this material about 30 years ago. This oddball star was discovered during an imaging survey of planetary nebulae. The images were taken Sept. 28, 1999 with Hubble's Wide Field and Planetary Camera 2. The images and results appear in the Aug. 1 issue of the Astrophysical Journal Letters. JPL designed and built the Wide Field and Planetary Camera 2. The Space Telescope Science Institute, Baltimore, Md, manages space operations for the Hubble Space Telescope for NASA's Office of Space Science, Washington, D.C. The Institute is operated by the Association of Universities for Research in Astronomy, Inc., for NASA, under contract with NASA's Goddard Space Flight Center, Greenbelt, Md. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. ##### |

What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. Thousands of sparkling young stars are nestled within the giant nebula NGC 3603. This stellar "jewel box" is one of the most massive young star clusters in the Milky Way Galaxy. NGC 3603 is a prominent star-forming region in the Carina spiral arm of the Milky Way, about 20,000 light-years away. This latest image from NASA's Hubble Space Telescope shows a young star cluster surrounded by a vast region of dust and gas. The image reveals stages in the life cycle of stars. |

What is a NASA Science Update? Major Hubble discoveries on NASA television ... Astronomers explain their Hubble discoveries at a press conference, called a NASA Science Update (NSU), broadcast on NASA television. The NSU includes a question and answer session with members of the media. NASA's Hubble Space Telescope has discovered 16 extrasolar planet candidates orbiting a variety of distant stars in the central region of our Milky Way galaxy. The planet bonanza was uncovered during a Hubble survey, called the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS). Hubble looked farther than has ever successfully been searched for extrasolar planets. Hubble peered at 180,000 stars in the crowded central bulge of our galaxy 26,000 light-years away or one-quarter the diameter of the Milky Way's spiral disk. The results will appear in the Oct. 5 issue of the journal Nature. Read more: * NASA Press Release [ http://hubblesite.org/newscenter/archive/releases/2006/34/text/ ] |

Hubble Sees Galaxy on Edge |
| General Information |
What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. This is a unique view of the disk galaxy NGC 5866 tilted nearly edge-on to our line-of-sight. Hubble's sharp vision reveals a crisp dust lane dividing the galaxy into two halves. The image highlights the galaxy's structure: a subtle, reddish bulge surrounding a bright nucleus, a blue disk of stars running parallel to the dust lane, and a transparent outer halo. NGC 5866 is a disk galaxy of type "S0" (pronounced s-zero). Viewed face on, it would look like a smooth, flat disk with little spiral structure. It remains in the spiral category because of the flatness of the main disk of stars as opposed to the more spherically rotund (or ellipsoidal) class of galaxies called "ellipticals." Such S0 galaxies, with disks like spirals and large bulges like ellipticals, are called 'lenticular' galaxies. NGC 5866 lies in the Northern constellation Draco, at a distance of 44 million light-years. It has a diameter of roughly 60,000 light-years only two-thirds the diameter of the Milky Way, although its mass is similar to our galaxy. This Hubble image of NGC 5866 is a combination of blue, green and red observations taken with the Advanced Camera for Surveys in February 2006. |

What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. The sharpest image ever taken of the large "grand design" spiral galaxy M81 is being released today at the American Astronomical Society Meeting in Honolulu, Hawaii. A spiral-shaped system of stars, dust, and gas clouds, the galaxy's arms wind all the way down into the nucleus. Though the galaxy is located 11.6 million light-years away, the Hubble Space Telescope's view is so sharp that it can resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. The Hubble data was taken with the Advanced Camera for Surveys in 2004 through 2006. This color composite was assembled from images taken in blue, visible, and infrared light. |
