This image from NASA Galaxy Evolution Explorer GALEX shows Messier 94, also known as NGC 4736, in ultraviolet light. It is located 17 million light-years away in the constellation Canes Venatici.

This montage combines observations from NASA Spitzer Space Telescope and NASA Galaxy Evolution Explorer GALEX spacecraft showing three examples of colliding galaxies from a new photo atlas of galactic train wrecks.

The galaxy UGC 1382 has been revealed to be far larger and stranger than previously thought. Astronomers relied on a combination of ground-based and space telescopes to uncover the true nature of this "Frankenstein galaxy." The composite image shows the same galaxy as viewed with different instruments. The component images are also available. In the image at left, UGC 1382 appears to be a simple elliptical galaxy, based on optical data from the Sloan Digital Sky Survey (SDSS). But spiral arms emerged when astronomers incorporated ultraviolet data from the Galaxy Evolution Explorer (GALEX) and deep optical data from SDSS, as seen in the middle image. Combining that with a view of low-density hydrogen gas (shown in green), detected at radio wavelengths by the Very Large Array, scientists discovered that UGC 1382 is a giant, and one of the largest isolated galaxies known. GALEX in particular was able detect very faint features because it operated from space, which is necessary for UV observations because ultraviolet light is absorbed by the Earth's atmosphere. Astronomers also used Stripe 82 of SDSS, a small region of sky where SDSS imaged the sky 80 times longer than the original standard SDSS survey. This enabled optical detection of much fainter features as well. http://photojournal.jpl.nasa.gov/catalog/PIA20695

The Blue Ring Nebula was discovered in 2004 by NASA's Galaxy Evolution Explorer (GALEX) mission. Astronomers think the nebula was created by the merger of two stars, and that we are seeing the system a few thousand years after the merger, when evidence of the collision is still apparent. The blue light in the image shows the debris cloud created by the merger. As the hot cloud of material expanded into space and cooled down, it formed hydrogen molecules that collided with the interstellar medium (the particles occupying the space between stars). These collisions caused the hydrogen molecules to radiate far-ultraviolet light, which was detected by GALEX. Yellow indicates near-ultraviolet light, also detected by GALEX, which is emitted by the star at the center of the nebula and many surrounding stars. Infrared light observed by NASA's Wide-field Infrared Survey Explorer (WISE) is also shown in red, and is primarily emitted by the central star. Detailed analysis of the WISE data revealed a ring of debris around the star – further evidence of a merger. Magenta indicates optical light — light visible to the human eye — collected using the Hale Telescope. This light comes from the shockwave at the front of the expanding debris cones. The optical light helped astronomers discover that the nebula actually consists of two cones moving away from the central star. The base of one cone is moving almost directly toward Earth, while the other is moving almost directly away, and the magenta light outlines the two bases. The blue region in the image shows where the cones overlap; the non-overlapping regions are too faint for GALEX to see. Figure A shows the orientation of the cones to Earth and the way they appear to overlap. https://photojournal.jpl.nasa.gov/catalog/PIA23867

This illustration shows a red dwarf star orbited by a hypothetical exoplanet. Red dwarfs tend to be magnetically active, displaying gigantic arcing prominences and a wealth of dark sunspots. Red dwarfs also erupt with intense flares that could strip a nearby planet's atmosphere over time, or make the surface inhospitable to life as we know it. By mining data from the Galaxy Evolution Explorer (GALEX) spacecraft, a team of astronomers identified dozens of flares at a range of durations and strengths. The team measured events with less total energy than many previously detected flares from red dwarfs. This is important because, although individually less energetic and therefore less hostile to life, smaller flares might be much more frequent and add up over time to produce a cumulative effect on an orbiting planet. https://photojournal.jpl.nasa.gov/catalog/PIA21473

A group of six streaking objects, the identities of which remain unknown, can be seen here flying across the telescope sight in this image from NASA Galaxy Evolution Explorer.

Since its launch in 2003, NASA Galaxy Evolution Explorer the space telescope originally designed to observe galaxies across the universe in ultraviolet light has discovered a festive sky blinking with flaring and erupting stars.

The Galaxy Evolution Explorer specializes in surveying galaxies in ultraviolet light. Its telescope, 50 centimeters (19.7 inches) in diameter, has a field of view that is much wider than most ground-based and space-based telescopes. This field of view, nearly three times the diameter of the Moon, allowed the Galaxy Evolution Explorer to discover seemingly newborn galaxies in our local universe. The telescope surveyed thousands of galaxies before finding three-dozen of these newborns. http://photojournal.jpl.nasa.gov/catalog/PIA05979

This image shows six of the three-dozen "ultraviolet luminous galaxies" spotted in our corner of the universe by NASA's Galaxy Evolution Explorer. These massive galaxies greatly resemble newborn galaxies that were common in the early universe. The discovery came as a surprise, because astronomers had thought that the universe's "birth-rate" had declined, and that massive galaxies were no longer forming. The galaxies, located in the center of each panel, were discovered after the Galaxy Evolution Explorer scanned a large portion of the sky with its highly sensitive ultraviolet-light detectors. Because young stars pack most of their light into ultraviolet wavelengths, young galaxies appear to the Galaxy Evolution Explorer like diamonds in a field of stones. Astronomers mined for these rare "gems" before, but missed them because they weren't able to examine a large enough slice of the sky. The Galaxy Evolution Explorer surveyed thousands of nearby galaxies before finding three-dozen newborns. While still relatively close in astronomical terms, these galaxies are far enough away to appear small to the Galaxy Evolution Explorer. Clockwise beginning from the upper left, they are called: GALEX_J232539.24+004507.1, GALEX_J231812.98-004126.1, GALEX_J015028.39+130858.5, GALEX_J021348.52+125951.3, GALEX_J143417.15+020742.5, GALEX_J020354.02-092452.5. http://photojournal.jpl.nasa.gov/catalog/PIA07143

Hot stars burn brightly in this new image from NASA Galaxy Evolution Explorer, showing the ultraviolet side of a familiar face. Approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way largest galactic neighbor.

Ultraviolet images such as this one from NASA's Galaxy Evolution Explorer suggest the M83 has unusual pockets of star formation separated by large distances from the spiral arms in the main disk of the galaxy. http://photojournal.jpl.nasa.gov/catalog/PIA07903

This image of the active galaxy Centaurus A was taken by NASA's Galaxy Evolution Explorer on June 7, 2003. The galaxy is located 30 million light-years from Earth and is seen edge on, with a prominent dust lane across the major axis. In this image the near ultraviolet emission is represented as green, and the far ultraviolet emission as blue. The galaxy exhibits jets of high energy particles, which were traced by the X-ray emission and measured by NASA's Chandra X-ray Observatory. These X-ray emissions are seen as red in the image. Several regions of ultraviolet emission can be seen where the jets of high energy particles intersect with hydrogen clouds in the upper left corner of the image. The emission shown may be the result of recent star formation triggered by the compression of gas by the jet. http://photojournal.jpl.nasa.gov/catalog/PIA04624

This artist's animation shows a typical young galaxy, teeming with hot, newborn stars and exploding supernovas. The supernovas are seen as white flashes of light. NASA's Galaxy Evolution Explorer spotted three-dozen young galaxies like the one shown here in our corner of the universe. It was able to see them with the help of its highly sensitive ultraviolet detectors. Because newborn stars radiate ultraviolet light, young galaxies light up brilliantly when viewed in ultraviolet wavelengths. The findings came as a surprise, because astronomers had thought that the universe's "birth-rate" had declined, and that massive galaxies were no longer forming. http://photojournal.jpl.nasa.gov/catalog/PIA07144

NASA Galaxy Evolution Explorer took this ultraviolet color image of the galaxy NGC5474 on June 7, 2003.

Since its launch five years ago, the Galaxy Evolution Explorer has photographed hundreds of millions of galaxies in ultraviolet light. M106 is one of those galaxies, 22 light years away, it strikes a pose in blue and gold for this new commemorative portrait. The galaxy's extended arms are the blue filaments that curve around its edge, creating its outer disk. Tints of blue in M106's arms reveal hot, young massive stars. Traces of gold toward the center show an older stellar population and indicate the presence of obscuring dust. From 24 million light-years away, neighboring galaxy NGC 4248 also makes a memorable appearance, sitting just right of M106. The irregular galaxy looks like a yellow smudge, with a bluish-white bar in the center. The galaxy's outer golden glow indicates a population of older stars, while the blue central region shows a younger stellar demographic. Dwarf galaxy UGC 7365 emerges at the bottom center of this image, as a faint yellow smudge directly below M106. This galaxy is not forming any new stars, and looks much smaller than M106 despite being closer to Earth, at 14 million light-years away. Over the past five years, the Galaxy Evolution Explorer has imaged half a billion objects over 27,000 square degrees of sky —equivalent to an area that would be covered by 138,000 full moons. The telescope orbits Earth every 94 minutes and travels approximately 408,470 million miles per day. Its overarching question is: how do galaxies grow and change over 10 billion years of cosmic history? M106, also known as NGC 4258, is located in the constellation Canes Venatici. This image is a two-color composite, where far-ultraviolet light is blue, and near-ultraviolet light is red. http://photojournal.jpl.nasa.gov/catalog/PIA10600

This is an ultraviolet color image of the galaxy NGC5398 taken by NASA Galaxy Evolution Explorer on June 7, 2003. NGC5398 is a barred spiral galaxy located 60 million light-years from Earth.

This single orbit exposure, ultraviolet color image of Messier 101 was taken by NASA's Galaxy Evolution Explorer on June 20, 2003. Messier 101 is a large spiral galaxy located 20 million light-years from Earth. This image is a short and medium "exposure" picture of the evolution of star formation in a spiral galaxy. The far ultraviolet emission detects the younger stars as concentrated in tight spiral arms, while the near ultraviolet emission, which traces stars living for more than 100 million years, displays the movement of the spiral pattern over a 100 million year period. The red stars in the foreground of the image are Milky Way stars. http://photojournal.jpl.nasa.gov/catalog/PIA04632

This artist concept illustrates a star flying through our galaxy at supersonic speeds, leaving a 13-light-year-long trail of glowing material in its wake. The star, named Mira pronounced my-rah after the latin word for wonderful.
