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 at 8 a.m. EDT on April 28th, 2003. Although originally planned as a 29-month mission, the NASA Senior Review Panel in 2006 recommended that the mission lifetime be extended. This is the official home page of the GALEX mission. http://www.galex.caltech.edu/ For decades, astronomers have gone about their business of studying the cosmos with the assumption that stars of certain sizes form in certain quantities http://www.galex.caltech.edu/newsroom/glx2009-04r.html http://www.galex.caltech.edu/newsroom/glx2009-04r.html Wed, 19 Aug 2009 10:00:00 PDT Engineers and scientists are continuing the recovery procedure for the far-ultraviolet instrument on NASA's Galaxy Evolution Explorer. On May 29, the instrument experienced an overcurrent condition and shut down. http://www.galex.caltech.edu/newsroom/glx2009-07s.html http://www.galex.caltech.edu/newsroom/glx2009-07s.html Thu, 9 Jul 2009 10:00:00 PDT On May 29, the Galaxy Evolution Explorer's far-ultraviolet instrument reported an overcurrent condition and shut down. The project reviewed data from the incident and confirmed it had the same characteristics as three previous incidents occurring in 2005, 2006 and 2007. http://www.galex.caltech.edu/newsroom/glx2009-06s.html http://www.galex.caltech.edu/newsroom/glx2009-06s.html Tue, 9 Jun 2009 10:00:00 PDT NASA's Galaxy Evolution Explorer Mission marks its sixth anniversary studying galaxies beyond our Milky Way through its sensitive ultraviolet telescope, the only such far-ultraviolet detector in space. http://www.galex.caltech.edu/newsroom/glx2009-01f.html http://www.galex.caltech.edu/newsroom/glx2009-01f.html Tue, 28 Apr 2009 14:50:00 PDT This new image of the 'Ghost of Jupiter' is being released as part of the 'Around the World in 80 Telescopes' event for the International Year of Astronomy. http://www.galex.caltech.edu/media/glx2009-03r_img01.html http://www.galex.caltech.edu/media/glx2009-03r_img01.html Fri, 03 Apr 2009 13:20:00 PDT A collection of NASA missions will be involved in a live event Friday, April 3, that will allow the public to get an inside look at how these missions are run.

Our portion is scheduled for 20:20 UTC (1:20 PM PDT) on Friday, April 3, 2009 live from Caltech. Spitzer Space Telescope, another space-based telescope project hosted at Caltech, will also participate and is scheduled for 21:20 UTC (2:20 PDT) on Friday, April 3 2009. http://www.100hoursofastronomy.org/program/75-live-24-hour-research-observatory-webcast http://www.100hoursofastronomy.org/program/75-live-24-hour-research-observatory-webcast Mon, 23 Mar 2009 10:00:00 PDT There is more than one way to make a dwarf galaxy, and NASA's Galaxy Evolution Explorer has found a new recipe. http://www.galex.caltech.edu/newsroom/glx2009-01r.html http://www.galex.caltech.edu/newsroom/glx2009-01r.html Wed, 18 Feb 2009 11:00:00 PDT NASA's Galaxy Evolution Explorer has lifted the veil off a ghost known to haunt the local universe, providing new insight into the formation and evolution of galaxies. http://www.galex.caltech.edu/newsroom/glx2008-02r.html http://www.galex.caltech.edu/newsroom/glx2008-02r.html Fri, 31 Oct 2008 15:00:00 PDT Since its launch five years ago, the Galaxy Evolution Explorer (GALEX) has photographed hundreds of millions of galaxies in ultraviolet light. M106 is one of those galaxies, and from 22 million light years away, it strikes a pose in blue and gold for this new commemorative portrait. http://www.galex.caltech.edu/newsroom/glx2008-02f.html http://www.galex.caltech.edu/newsroom/glx2008-02f.html Mon, 28 Apr 2008 12:00:00 PDT A new image from NASA's Galaxy Evolution Explorer shows baby stars sprouting in the backwoods of a galaxy -- a relatively desolate region of space more than 100,000 light-years from the galaxy's bustling center. http://www.galex.caltech.edu/newsroom/glx2008-01r.html http://www.galex.caltech.edu/newsroom/glx2008-01r.html Wed, 16 Apr 2008 10:00:00 PDT As the most sensitive ultraviolet telescope ever launched, NASA's Galaxy Evolution Explorer (GALEX) scouts galaxies, or "stellar communities," over 10 billion years of cosmic history. Since its launch in April 2003, GALEX has glimpsed hundreds of thousands of galaxies -- revealing some of the hottest stellar neighborhoods in the cosmos. Here's a look back at some of the mission's most memorable views. http://www.galex.caltech.edu/newsroom/glx2008-01f.html http://www.galex.caltech.edu/newsroom/glx2008-01f.html Thu, 21 Feb 2008 12:00:00 PDT
