GALEX
The Galaxy Evolution Explorer (GALEX) is an orbiting ultraviolet space telescope launched on April 28, 2003, and operated until early 2012.
History
An airlaunched Pegasus rocket placed the craft into a nearly circular orbit at an altitude of 697 kilometres (433 mi) and an inclination to the Earth's equator of 29 degrees.
The first observation was dedicated to the crew of the Space Shuttle Columbia and images the sky in the constellation Hercules, taken on May 21, 2003. This region was selected because it had been directly overhead the shuttle at the time of its last contact with the NASA Mission Control Center.
After its primary mission of 29 months, observation operations were extended to almost 9 years with NASA placing it into standby mode on 7 Feb 2012.
NASA cut off financial support for operations of GALEX in early February 2011 as it was ranked lower than other projects which were seeking a limited supply of funding. The mission's life-cycle cost to NASA was $150.6 million. The California Institute of Technology negotiated to transfer control of GALEX and its associated ground control equipment to the California Institute of Technology in keeping with the Stevenson-Wydler Technology Innovation Act. Under this Act, excess research equipment owned by the US government can be transferred to educational institutions and non-profit organizations. In May 2012, GALEX operations were transferred to Caltech.

Galaxy formation and evolution
The study of galaxy formation and evolution is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning, the formation of the first galaxies, the way galaxies change over time, and the processes that have generated the variety of structures observed in nearby galaxies.
Galaxy formation is hypothesized to occur, from structure formation theories, as a result of tiny quantum fluctuations in the aftermath of the Big Bang. The simplest model for this that is in general agreement with observed phenomena is the Λ-Cold Dark Matter cosmology; that is to say that clustering and merging is how galaxies gain in mass, and can also determine their shape and structure.
Commonly observed properties of galaxies
Some notable observed features of galaxy structure (including our own Milky Way) that astronomers wish to explain with galactic formation theories, include (but are certainly not limited to) the following:

Galaxy Evolution Explorer (GALEX) (James Fanson)
The Galaxy Evolution Explorer (GALEX) mission was selected in 1997 and launched in 2003, performing the first extragalactic wide-area imaging and spectroscopic surveys in the ultraviolet. Designed to map the history of star formation over 80 percent of the history of the universe, GALEX has changed our understanding of where and when stars form in galaxies over cosmic time. Along the way several, surprising discoveries were made, including the first detection of a 13-light-year-long tail streaming behind the star Mira, and the first observation of the ultraviolet flash at the beginning of a supernova explosion. Although a small mission, GALEX developed the largest microchannel plate detectors ever flown in space. Begun under the faster-better-cheaper era, implementation changed radically...

GALEX (Galaxy Evolution Explorer; New Horizons)
NASA Mission Update: GALEX In the early 1900s, Edwin Hubble made the startling discovery that our Milky Way galaxy is not alone, but one of many galaxies, or "island universes," swimming in the sea of space. How are galaxies born and how do they grow? Since its launch in April, 2003, NASA's Galaxy Evolution Explorer has photographed in ultraviolet light hundreds of millions of these "island universes" across nine billion years of time, helping piece together the evolution of these cosmic species.

GALEXs observations are telling scientists how galaxies, the basic structures of our Universe, evolve and change. Additionally, GALEX observations are investigating the causes of star formation during a period when most of the stars and elements we see today had their origins.
Led by the California Institute of Technology, GALEX is conducting several first-of-a-kind sky surveys, including an extra-galactic (beyond our galaxy) ultraviolet all-sky survey. During its mission GALEX will produce the first comprehensive map of a Universe of galaxies under construction, bringing us closer to understanding how galaxies like our own Milky Way were formed.
GALEX is also identifying celestial objects for further study by ongoing and future missions and GALEX data now populates a large, unprecedented archive available to the entire astronomical community and to the general public.
Scientists would like to understand when the stars that we see today and the chemical elements that make up our Milky Way galaxy were formed. With its ultraviolet observations, GALEX is filling in one of the key pieces of this puzzle.

Although a small mission, GALEX developed the largest microchannel plate detectors ever flown in space. Begun under the faster-better-cheaper era, implementation changed radically following a string of mission failures in the late nineties. Project implementation encountered an unusual array of technical and programmatic challenges, producing a useful collection of lessons learned. GALEX was ultimately flown and checked out in orbit for $72 million. Originally intended to operate for twenty-eight months, GALEX continues to produce unique data more than eight years later.

NASA Mission Update: GALEX
In the early 1900s, Edwin Hubble made the startling discovery that our Milky Way galaxy is not alone, but one of many galaxies, or "island universes," swimming in the sea of space.
How are galaxies born and how do they grow? Since its launch in April, 2003, NASA's Galaxy Evolution Explorer has photographed in ultraviolet light hundreds of millions of these "island universes" across nine billion years of time, helping piece together the evolution of these cosmic species.
Zlatan Tsvetanov: "The fact that it's extremely sensitive in the region where young forming stars are the most easy to see, makes it an extremely powerful machine for studying the evolution of galaxies, star formation rates, also discovering some unexpected things on the way."
Scientists have only begun to pore through the data GALEX has collected over the last five years: ultraviolet images of half a billion objects over 27,000 square degrees of sky. That's an area that would need 138,000 full Earth moons to cover.
Zlatan Tsvetanov: "GALEX has already demonstrated that there are things that we did not know, we did not expect, and they come about very obviously when you have the right tools. One of the most stunning examples is the tail of the very well know variable star called MIRA, which was observed for 400 years, but nobody suspected it had a tail of several degrees in the sky; and It's a pretty stunning discovery..."
To learn more about the GALEX mission, see a portrait of a galaxy's life, and have a closer look at some of GALEX's stunning imagery, like this picture of galaxy M106 taken from 22-million-light years away, visit www.nasa.gov/galex.
A Real Shooting Star
A close-up view of a star racing through space faster than a speeding bullet can be seen in this image from NASA's Galaxy Evolution Explorer. The star, called Mira (pronounced My-rah), is traveling at 130 kilometers per second, or 291,000 miles per hour. As it hurls along, it sheds material that will be recycled into new stars, planets and possibly even life.

http://facebook.com/ScienceReason ... The Galaxy Evolution Explorer (GALEX) is an orbiting space telescope observing galaxies in ultraviolet light across 10 billion years of cosmic history. A Pegasus rocket launched GALEX into orbit in 2003. Although originally planned as a 29-month mission, the NASA Senior Review Panel in 2006 recommended that the mission lifetime be extended.

GALEXs observations are telling scientists how galaxies, the basic structures of our Universe, evolve and change. Additionally, GALEX observations are investigating the causes of star formation during a period when most of the stars and elements we see today had their origins.
Led by the California Institute of Technology, GALEX is conducting several first-of-a-kind sky surveys, including an extra-galactic (beyond our galaxy) ultraviolet all-sky survey. During its mission GALEX will produce the first comprehensive map of a Universe of galaxies under construction, bringing us closer to understanding how galaxies like our own Milky Way were formed.
GALEX is also identifying celestial objects for further study by ongoing and future missions and GALEX data now populates a large, unprecedented archive available to the entire astronomical community and to the general public.
Scientists would like to understand when the stars that we see today and the chemical elements that make up our Milky Way galaxy were formed. With its ultraviolet observations, GALEX is filling in one of the key pieces of this puzzle.

The Galaxy Evolution Explorer (GALEX) is an orbiting ultraviolet space telescope launched on April 28, 2003. A Pegasus rocket placed the craft into a nearly circular orbit at an altitude of 697 kilometres (433 mi) and an inclination to the Earth's equator of 29 degrees.
The first observation was dedicated to the crew of the Space Shuttle Columbia and images the sky in the constellation Hercules, taken on May 21, 2003. This region was selected because it had been directly overhead the shuttle at the time of its last contact with the NASA Mission Control Center.

The Galaxy Evolution Explorer (GALEX) mission was selected in 1997 and launched in 2003, performing the first extragalactic wide-area imaging and spectroscopic surveys in the ultraviolet. Designed to map the history of star formation over 80 percent of the history of the universe, GALEX has changed our understanding of where and when stars form in galaxies over cosmic time. Along the way several, surprising discoveries were made, including the first detection of a 13-light-year-long tail streaming behind the star Mira, and the first observation of the ultraviolet flash at the beginning of a
supernova explosion.
Although a small mission, GALEX developed the largest microchannel plate detectors ever flown in space. Begun under the faster-better-cheaper era, implementation changed radically following a string of mission failures in the late nineties. Project implementation encountered an unusual array of technical and programmatic challenges, producing a useful collection of lessons learned. GALEX was ultimately flown and checked out in orbit for $72 million. Originally intended to operate for twenty-eight months, GALEX continues to produce unique data more than eight years later.

NASA Mission Update: GALEX
In the early 1900s, Edwin Hubble made the startling discovery that our Milky Way galaxy is not alone, but one of many galaxies, or "island universes," swimming in the sea of space.
How are galaxies born and how do they grow? Since its launch in April, 2003, NASA's Galaxy Evolution Explorer has photographed in ultraviolet light hundreds of millions of these "island universes" across nine billion years of time, helping piece together the evolution of these cosmic species.
Zlatan Tsvetanov: "The fact that it's extremely sensitive in the region where young forming stars are the most easy to see, makes it an extremely powerful machine for studying the evolution of galaxies, star formation rates, also discovering some unexpected things on the way."
Scientists have only begun to pore through the data GALEX has collected over the last five years: ultraviolet images of half a billion objects over 27,000 square degrees of sky. That's an area that would need 138,000 full Earth moons to cover.
Zlatan Tsvetanov: "GALEX has already demonstrated that there are things that we did not know, we did not expect, and they come about very obviously when you have the right tools. One of the most stunning examples is the tail of the very well know variable star called MIRA, which was observed for 400 years, but nobody suspected it had a tail of several degrees in the sky; and It's a pretty stunning discovery..."
To learn more about the GALEX mission, see a portrait of a galaxy's life, and have a closer look at some of GALEX's stunning imagery, like this picture of galaxy M106 taken from 22-million-light years away, visit www.nasa.gov/galex.
A Real Shooting Star
A close-up view of a star racing through space faster than a speeding bullet can be seen in this image from NASA's Galaxy Evolution Explorer. The star, called Mira (pronounced My-rah), is traveling at 130 kilometers per second, or 291,000 miles per hour. As it hurls along, it sheds material that will be recycled into new stars, planets and possibly even life.

GALEX
The Galaxy Evolution Explorer (GALEX) is an orbiting ultraviolet space telescope launched on April 28, 2003, and operated until early 2012.
History
An airlaunched Pegasus rocket placed the craft into a nearly circular orbit at an altitude of 697 kilometres (433 mi) and an inclination to the Earth's equator of 29 degrees.
The first observation was dedicated to the crew of the Space Shuttle Columbia and images the sky in the constellation Hercules, taken on May 21, 2003. This region was selected because it had been directly overhead the shuttle at the time of its last contact with the NASA Mission Control Center.
After its primary mission of 29 months, observation operations were extended to almost 9 years with NASA placing it into standby mode on 7 Feb 2012.
NASA cut off financial support for operations of GALEX in early February 2011 as it was ranked lower than other projects which were seeking a limited supply of funding. The mission's life-cycle cost to NASA was $150.6 million. The California Institute of Technology negotiated to transfer control of GALEX and its associated ground control equipment to the California Institute of Technology in keeping with the Stevenson-Wydler Technology Innovation Act. Under this Act, excess research equipment owned by the US government can be transferred to educational institutions and non-profit organizations. In May 2012, GALEX operations were transferred to Caltech.
