Hubble's New Camera Delivers Breathtaking Views of the Universe
Jubilant astronomers unveiled humankind's most spectacular views of the universe, courtesy of the newly installed Advanced Camera for Surveys (ACS) aboard NASA's Hubble Space Telescope. Among the suite of four ACS photographs to demonstrate the camera's capabilities is a stunning view of a colliding galaxy dubbed the "Tadpole" (UGC10214). Set against a rich tapestry of 6,000 galaxies, the Tadpole, with its long tail of stars, looks like a runaway pinwheel firework. Another picture depicts a spectacular collision between two spiral galaxies -- dubbed "The Mice" -- that presages what may happen to our own Milky Way several billion years from now when it collides with the neighboring galaxy in the constellation Andromeda. Looking closer to home, ACS imaged the "Cone Nebula," a craggy-looking mountaintop of cold gas and dust that is a cousin to Hubble's iconic "pillars of creation" in the Eagle Nebula, photographed in 1995. Peering into a celestial maternity ward called the Omega Nebula or M17, ACS revealed a watercolor fantasy-world of glowing gases, where stars and perhaps embryonic planetary systems are forming.
NASA's Hubble Space Telescope has measured the largest object discovered in the solar system since the discovery of Pluto 72 years ago. Approximately half the size of Pluto, the icy world is called "Quaoar" (pronounced kwa-whar). Quaoar is about 4 billion miles away, more than a billion miles farther than Pluto. Like Pluto, Quaoar dwells in the Kuiper belt, an icy belt of comet-like bodies extending 7 billion miles beyond Neptune's orbit.
Hands-On Book of Hubble Images Allows the Visually Impaired to "Touch the Universe"
A new book of majestic images taken by NASA's Hubble Space Telescope brings the wonders of our universe to the fingertips of the blind. Called "Touch the Universe: A NASA Braille Book of Astronomy," the 64-page book presents color images of planets, nebulae, stars, and galaxies. Each image is embossed with lines, bumps, and other textures. The raised patterns translate colors, shapes, and other intricate details of the cosmic objects, allowing visually impaired people to feel what they cannot see. Braille and large-print descriptions accompany each of the book's 14 photographs, making the design of this book accessible to readers of all visual abilities.
Hubble Watches Light from Mysterious Erupting Star Reverberate Through Space
In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star, called V838 Monocerotis, has long since faded back to obscurity. But observations by NASA's Hubble Space Telescope of a phenomenon called a "light echo" around the star have uncovered remarkable new features. These details promise to provide astronomers with a CAT-scan-like probe of the three-dimensional structure of shells of dust surrounding an aging star.
NASA Approves James Webb Space Telescope Mirror Architecture
NASA today announced a major milestone in the development of the James Webb Space Telescope (JWST), the selection of a beryllium-based mirror technology for the telescope's 6.5-meter primary mirror. The JWST prime contractor, Northrop Grumman, Redondo Beach, Calif., recommended to NASA the mirror technology, supplied by Ball Aerospace & Technologies Corporation, Boulder, Colo., be selected for the JWST primary mirror.
NASA's Great Observatories May Unravel 400-Year Old Supernova Mystery
Four hundred years ago, sky watchers, including the famous astronomer Johannes Kepler, were startled by the sudden appearance of a "new star" in the western sky, rivaling the brilliance of the nearby planets. Now, astronomers using NASA's three Great Observatories are unraveling the mysteries of the expanding remains of Kepler's supernova, the last such object seen to explode in our Milky Way galaxy.
Looks can be deceiving, especially when it comes to celestial objects like galaxies and nebulas. These objects are so far away that astronomers cannot see their three-dimensional structure. The Helix Nebula, for example, resembles a doughnut in colorful images. Earlier images of this complex object – the gaseous envelope ejected by a dying, sun-like star – did not allow astronomers to precisely interpret its structure. One possible interpretation was that the Helix's form resembled a snake-like coil. Now, a team of astronomers using NASA's Hubble Space Telescope has established that the Helix's structure is even more perplexing. Their evidence suggests that the Helix consists of two disks nearly perpendicular to each other.
Hubble Celebrates 15th Anniversary with Spectacular New Images
During the 15 years NASA's Hubble Space Telescope has orbited the Earth, it has taken more than 700,000 photos of the cosmos; images that have awed, astounded and even confounded astronomers and the public.
NASA released new views today of two of the most well-known objects Hubble has ever observed: the Whirlpool Galaxy (spiral galaxy M51)
and the Eagle Nebula
. These new images are among the largest and sharpest Hubble has ever taken. They were made with Hubble's newest camera, the Advanced Camera for Surveys (ACS). The images are so incredibly sharp, they could be enlarged to billboard size and still retain stunning details.
For the 15th anniversary, scientists used the ACS to record a new region of the eerie-looking Eagle Nebula. The Eagle Nebula image reveals a tall, dense tower of gas being sculpted by ultraviolet light from a group of massive, hot stars. The new Whirlpool Galaxy image showcases the spiral galaxy's classic features, from its curving arms, where newborn stars reside, to its yellowish central core that serves as home for older stars. A feature of considerable interest is the companion galaxy located at the end of one of the spiral arms.
Hubble Space Telescope Begins "Two-Gyro" Science Operations
NASA's Hubble Space Telescope entered a new era of science operations this week, when engineers shut down one of the three operational gyroscopes aboard the observatory. The two-gyro mode is expected to preserve the operating life of the third gyro and extend Hubble's science observations through mid-2008, an eight-month extension. Backdropped by the horizon of the blue and white Earth and the blackness of space, the Hubble Space Telescope floats gracefully after the release from the Space Shuttle's robotic arm at the close of a successful servicing mission in March of 2002.
Today's workplace for "hard-discipline" organizations, such as science, technology, engineering and medicine requires a more diverse and balanced set of skills for success than at any other time in history. Organizational dynamics, diverse cultures, genders, professions and backgrounds, as well as environmental, consumer and business demands require an emphasis on interpersonal, ethical, and relational competencies as well as traditional technical orientations.
Several organizations and institutions, including the Space Telescope Science Institute in Baltimore, will address these issues in a six-part lecture series entitled "Hard Science/Soft Skills: Fostering Civility in the Scientific Workplace."
NASA announced today plans for a fifth servicing mission to the Hubble Space Telescope. Shuttle astronauts will visit the telescope to extend and improve the observatory's capabilities through 2013.
NASA Unveils Cosmic Images Book in Braille for Blind Readers
At a ceremony today at the National Federation of the Blind, NASA unveiled a new book that brings majestic images taken by its Great Observatories to the fingertips of the blind. "Touch the Invisible Sky" is a 60-page book with color images of nebulae, stars, galaxies and some of the telescopes that captured the original pictures. Braille and large-print descriptions accompany each of the book's 28 photographs, making the book's design accessible to readers of all visual abilities.The book contains spectacular images from the Hubble Space Telescope, Chandra X-ray Observatory, Spitzer Space Telescope and powerful ground-based telescopes. The celestial objects are presented as they appear through visible-light telescopes and different spectral regions invisible to the naked eye, from radio to infrared, visible, ultraviolet and X-ray light.

Starry-Eyed Hubble Celebrates 20 Years of Awe and Discovery
NASA's best-recognized, longest-lived, and most prolific space observatory zooms past a threshold of 20 years of operation this month. On April 24, 1990, the space shuttle and crew of STS-31 were launched to deploy the Hubble Space Telescope into a low Earth orbit. What followed was one of the most remarkable sagas of the space age. Hubble's unprecedented capabilities made it one of the most powerful science instruments ever conceived by humans, and certainly the one most embraced by the public. Hubble discoveries revolutionized nearly all areas of current astronomical research, from planetary science to cosmology. And, its pictures were unmistakably out of this world. This brand new Hubble photo is of a small portion of one of the largest seen star-birth regions in the galaxy, the Carina Nebula. Towers of cool hydrogen laced with dust rise from the wall of the nebula. The scene is reminiscent of Hubble's classic "Pillars of Creation" photo from 1995, but is even more striking in appearance. The image captures the top of a three-light-year-tall pillar of gas and dust that is being eaten away by the brilliant light from nearby bright stars. The pillar is also being pushed apart from within, as infant stars buried inside it fire off jets of gas that can be seen streaming from towering peaks like arrows sailing through the air.
NASA and the Space Telescope Science Institute (STScI) are celebrating Hubble's journey of exploration with this stunning new picture, online educational activities, an opportunity for people to explore galaxies as armchair scientists, and an opportunity for astronomy enthusiasts to send in their own personal greetings to Hubble for posterity.
