NASA celebrates Chandra X-Ray Observatory's 10th anniversary
July 24, 2009Ten years ago, on July 23, 1999, NASA's Chandra X-ray Observatory was launched aboard the space shuttle Columbia and deployed into orbit. Chandra has doubled its original five-year mission, ushering in an unprecedented decade of discovery for the high-energy universe.
With its unrivaled ability to create high-resolution X- ray images, Chandra has enabled astronomers to investigate phenomena as diverse as comets, black holes, dark matter and dark energy.
"Chandra's discoveries are truly astonishing and have made dramatic changes to our understanding of the universe and its constituents," said Martin Weisskopf, Chandra project scientist at NASA's Marshall Space Flight Center in Huntsville, Ala.
The science that has been generated by Chandra -- both on its own and in conjunction with other telescopes in space and on the ground -- has had a widespread, transformative impact on 21st century astrophysics. Chandra has provided the strongest evidence yet that dark matter must exist. It has independently confirmed the existence of dark energy and made spectacular images of titanic explosions produced by matter swirling toward supermassive black holes.
To commemorate the 10th anniversary of Chandra, three new versions of classic Chandra images will be released during the next three months. These images, the first of which is available Thursday, provide new data and a more complete view of objects that Chandra observed in earlier stages of its mission. The image being released today is of E0102-72, the spectacular remains of an exploded star.
"The Great Observatories program -- of which Chandra is a major part -- shows how astronomers need as many tools as possible to tackle the big questions out there," said Ed Weiler, associate administrator of NASA's Science Mission Directorate at NASA Headquarters in Washington. NASA's other "Great Observatories" are the Hubble Space Telescope, Compton Gamma-Ray Observatory and Spitzer Space Telescope.
The next image will be released in August to highlight the anniversary of when Chandra opened up for the first time and gathered light on its detectors. The third image will be released during "Chandra's First Decade of Discovery" symposium in Boston, which begins Sept. 22.
"I am extremely proud of the tremendous team of people who worked so hard to make Chandra a success," said Harvey Tananbaum, director of the Chandra X-ray Center at the Smithsonian Astrophysical Observatory in Cambridge, Mass. "It has taken partners at NASA, industry and academia to make Chandra the crown jewel of high-energy astrophysics."
Tananbaum and Nobel Prize winner Riccardo Giacconi originally proposed Chandra to NASA in 1976. Unlike the Hubble Space Telescope, Chandra is in a highly elliptical orbit that takes it almost one third of the way to the moon, and was not designed to be serviced after it was deployed.
Marshall manages the Chandra program for NASA's Science Mission Directorate. The Smithsonian Astrophysical Observatory controls science and flight operations from the Chandra X-ray Center.

Chandra X-Ray Observatory Current Events and Chandra X-Ray Observatory News RSSCarbon atmosphere discovered on neutron star
Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object.
Galaxy cluster smashes distance record
The most distant galaxy cluster yet has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes.
New vista of Milky Way center unveiled
A dramatic new vista of the center of the Milky Way galaxy from NASA's Chandra X-ray Observatory exposes new levels of the complexity and intrigue in the Galactic center.
Trigger-happy star formation
A new study from two of NASA's Great Observatories provides fresh insight into how some stars are born, along with a beautiful new image of a stellar nursery in our Galaxy.
Galaxies coming of age in cosmic blobs
The "coming of age" of galaxies and black holes has been pinpointed, thanks to new data from NASA's Chandra X-ray Observatory and other telescopes.
Ghost Remains After Black Hole Eruption
NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole. This is the first detection of such a high-energy apparition, and scientists think it is evidence of a huge eruption produced by the black hole.
Peering deep into space
People have always wondered where we, our Earth, our galaxy, come from. A group of scientist has now driven that quest one step further and taken a peak at how the stars that gave rise to most of the material found on our universe formed over cosmic history.
Resolving a galactic mystery
An extremely deep Chandra X-ray Observatory image of a region near the center of our Galaxy has resolved a long-standing mystery about an X-ray glow along the plane of the Galaxy.
A young pulsar shows its hand
A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years.
Erratic Black Hole Regulates Itself
New results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce. These results suggest that these black holes have a mechanism for regulating the rate at which they grow.

Revealing the Universe: The Making of the Chandra X-ray Observatory by Wallace Tucker (Author), Karen Tucker (Author) When the first X-ray detectors revealed many places in the universe that are too hot to be seen by optical and radio telescopes, pioneering X-ray astronomers realized they were onto something big. They knew that a large X-ray observatory must be created if they were ever to understand such astonishing phenomena as neutron stars, supernovas, black holes, and dark matter. What they could not know was how monumental in time, money, and effort this undertaking would be. Revealing the Universe tells the story of the Chandra X-ray Observatory. From the first proposal for a large X-ray telescope in 1970 to the deployment of Chandra by the Space Shuttle Columbia in 1999, this book chronicles the technical feats, political struggles, and personal dramas that transformed an inspired... |

The Restless Universe: Understanding X-Ray Astronomy in the Age of Chandra and Newton by Eric M. Schlegel (Author) Carl Sagan once noted that there is only one generation that gets to see things for the first time. We are in the midst of such a time right now, standing on the threshold of discovery in the young and remarkable field of X-ray astronomy. In The Restless Universe, astronomer Eric Schlegel offers readers an informative survey of this cutting-edge science. Two major space observatories launched in the last few years--NASA's Chandra and the European Newton--are now orbiting the Earth, sending back a gold mine of data on the X-ray universe. Schlegel, who has worked on the Chandra project for seven years, describes the building and launching of this space-based X-ray observatory. But the book goes far beyond the story of Chandra. What Schlegel provides here is the background a nonscientist... |
