#HubbleFriday This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo. The galaxy is part of the Virgo Cluster, a gathering of galaxies that is over 1,200 strong. This image combines infrared, ultraviolet and visible light gathered by the Wide Field and Planetary Camera 2 on Hubble. This camera was operational between 1994 and 2010, producing images with an unusual staircase-like shape as seen here. This is because the camera was made up of four light detectors with overlapping fields of view, one of which gave a higher magnification than the other three. When the four images are combined together in one picture, the high-magnification image needs to be reduced in size in order for the image to align properly. This produces an image with a layout that looks like steps. Messier 90 is remarkable; it is one of the few galaxies seen to be traveling toward the Milky Way, not away from it. The galaxy’s light reveals this incoming motion in a phenomenon known as blueshift. In simple terms, the galaxy is compressing the wavelength of its light as it moves towards us, like a slinky being squashed when you push on one end. This increases the frequency of the light and shifts it towards the blue end of the spectrum. As our universe is expanding, almost all of the galaxies we see in the universe are moving away from us, and we therefore see their light more towards the red end of the spectrum, known as redshift. Messier 90, however, appears to be a rare exception. For more information, follow the link in our bio. Image credit: ESA/Hubble & NASA, W. Sargent et al.

Join John, EVA engineer Ed Rezac, and astronaut trainer Christy Hansen in this final episode of Hubble Tool Time to learn about creating a Fastener Capture Plate to capture 111 screws in order to repair the Space Telescope Imaging Spectrograph on Servicing Mission 4 in 2009. Retired NASA astronaut John Grunsfeld hosts this six-part mini-series about the tools used on the Hubble Space Telescope servicing missions. Hubble was uniquely designed to be serviced in space so that components could be repaired and upgraded. Astronauts using custom-designed tools performed challenging spacewalks on five servicing missions from 1993 to 2009 to keep Hubble operating so that it could change our fundamental understanding of the universe. In addition to enabling Hubble's scientific discoveries, the tools developed by teams at NASA's Goddard Space Flight Center and tested in collaboration with the Johnson Space Center furthered NASA's human exploration capabilities. These tools and the knowledge gleaned from the Hubble servicing missions are used today by astronauts on the International Space Station, and will be critical to NASA's future crewed missions to the Moon and Mars.

The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets. The right side of the galaxy is ablaze with star formation, shown in the plethora of young blue stars and star-incubating pinkish nebulas. The left side, however, looks intact. It contains hints of the galaxy’s previous spiral structure, which, at one time, was undergoing normal galactic evolution. The larger culprit galaxy, NGC 4490, is off the bottom of the frame. The two galaxies sideswiped each other millions of years ago and are now 24,000 light-years apart. The gravitational tug-of-war between them created rippling patches of higher-density gas and dust within both galaxies. This activity triggered a flurry of star formation. This galaxy is a nearby example of the kind of cosmic bumper-car activity that was more common billions of years ago when the universe was smaller and galaxies were closer together.

Ten years ago, Hubble's Servicing Mission 4 took place, becoming the most ambitious and complicated to date. Changing out two major science instruments and repairing two others while in space helped to make this mission truly memorable. Thanks to the astronauts of SM4, the Hubble Space Telescope is at the apex of its power and capabilities. To celebrate that important moment in history, NASA has gathered the footage of Servicing Mission 4 for posterity's sake, and archived hours of footage for all to use.

On May 11, 2009, the brave crew of Space Shuttle Atlantis lifted off to make NASA's Hubble Space Telescope more powerful than ever before. Hubble's Servicing Mission 4 (SM4) was the most ambitious and complicated to date. Changing out two major science instruments and repairing two others while in space helped to make this mission truly memorable. Thanks to the astronauts of SM4, the Hubble Space Telescope is at the apex of its power and capabilities. To celebrate SM4’s 10 year anniversary, this video gives a quick and in-depth review on the accomplishments of this historic mission. The tools and the knowledge gleaned from SM4 are used today by astronauts on the International Space Station, and will be critical to NASA's future crewed missions to the Moon and Mars.

#HubbleFriday Dotted across the sky in the constellation of Pictor (the Painter’s Easel) is the galaxy cluster highlighted here by Hubble: SPT-CL J0615-5746, or SPT0615 for short. SPT0615, first discovered by the South Pole Telescope less than a decade ago, is a massive cluster of galaxies, one of the farthest observed to cause gravitational lensing. Gravitational lensing occurs when light from a background object is deflected around mass between the object and the observer. Among the identified background objects, there is SPT0615-JD, a galaxy that is thought to have emerged just 500 million years after the big bang. This puts it among the very earliest structures to form in the universe. It is also the farthest galaxy ever imaged by means of gravitational lensing. Just as ancient paintings can tell us about the period of history in which they were painted, so too can ancient galaxies tell us about the era of the universe in which they existed. To learn about cosmological history, astronomers explore the most distant reaches of the universe, probing ever further out into the cosmos. The light from distant objects travels to us from so far away that it takes an immensely long time to reach us, meaning that it carries information from the past — information about the time at which it was emitted. By studying such distant objects, astronomers are continuing to fill the gaps in our picture of what the very early universe looked like, and uncover more about how it evolved into its current state.

In 1877, Edouard Stephan discovered a tight visual grouping of five galaxies located in the constellation Pegasus. The galaxies of Stephan's Quintet are both overlapping and interacting, and have become the most famous among the compact groups of galaxies. Astronomers have long known that four of the galaxies (all of which are yellowish-white in this video) form a physical group in space, while the fifth (bluish) is a foreground galaxy. In addition, a sixth galaxy (yellowish-white and on the far left) is likely to be part of the physical grouping. Hence, this 2D quintet that is a 3D quartet may actually be a 2D sextet that is a 3D quintet. This visualization makes apparent the spatial distribution of these galaxies. The video starts with a view that matches our 2D perspective. As the sequence travels in 3D, the foreground blue spiral, NGC 7320, quickly passes by the camera. The possible sixth galaxy member on the left, NGC 7320C, is seen at roughly the same distance as the remaining four galaxies. The camera turns to pass between two strongly interacting galaxies, NGC 7319 (left) and NGC 7318B (right), with each galaxy's spiral structure distorted by the gravitational interaction. In contrast, NGC 7318B overlaps in 2D with the more distant elliptical NGC 7318A, but does not have a strong interaction. The other elliptical, NGC 7317, is also seen as more distant than the strongly interacting pair. In 3D, the four or five galaxies in this group are gathered together by their mutual gravity, and may collide and merge together in the future.

#HubbleFriday Few of the universe’s residents are as iconic as the spiral galaxy. These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust, creating truly awesome scenes — especially when viewed through a telescope such as Hubble. In fact, this image from Hubble frames a perfect spiral specimen: the stunning NGC 2903. NGC 2903 is located about 30 million light-years away in the constellation of Leo, and was studied as part of a Hubble survey of the central regions of roughly 145 nearby disk galaxies. This study aimed to help astronomers better understand the relationship between the black holes that lurk at the cores of galaxies like these, and the rugby-ball-shaped bulge of stars, gas and dust at the galaxy’s center — such as that seen in this image.
