#HubbleFriday This image shows an irregular galaxy named IC 10, a member of the Local Group — a collection of over 50 galaxies in our cosmic neighborhood that includes the Milky Way. IC 10 is a remarkable object. It is the closest-known starburst galaxy, meaning that it is undergoing a furious bout of star formation fueled by ample supplies of cool hydrogen gas. This gas condenses into vast molecular clouds, which then form into dense knots where pressures and temperatures reach a point sufficient to ignite nuclear fusion, thus giving rise to new generations of stars. As an irregular galaxy, IC 10 lacks the majestic shape of spiral galaxies such as the Milky Way, or the rounded, ethereal appearance of elliptical galaxies. It is a faint object, despite its relative proximity to us of 2.2 million light-years. In fact, IC 10 only became known to humankind in 1887, when American astronomer Lewis Swift spotted it during an observing campaign. The small galaxy remains difficult to study even today, because it is located along a line-of-sight which is chock-full of cosmic dust and stars. For more information, follow the link in our bio.

#HubbleClassic #OTD in 1997 Hubble released this image of a 250-mile-high plume (at left) spouting from Jupiter's volcanic moon Io. Erupting from Io's Pele volcano, the gas & dust must've been blasted at over 2,000 miles per hour to form a plume that big. For more information on Hubble, follow the link in our bio.

#HubbleFriday When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae. A supernova event is incredibly energetic and intensely luminous — so much so that it forms what looks like an especially bright new star that slowly fades away over time. These exploding stars glow so incredibly brightly when they first form that they can be spotted from afar using telescopes such as Hubble. The subject of this image, a spiral galaxy named NGC 4051 — about 45 million light-years from Earth — has hosted multiple supernovae in past years. The first was spotted in 1983 (SN 1983I), the second in 2003 (SN 2003ie), and the most recent in 2010 (SN 2010br). These explosive events were seen scattered throughout the center and spiral arms of NGC 4051. SN 1983I and SN 2010br were both categorized as Type Ic supernovae. This type of supernova is produced by the core collapse of a massive star that has lost its outer layer of hydrogen and helium, either via winds or by mass transfer to a companion star. Because of this, Type Ic — and also Type Ib — supernovae are sometimes referred to as stripped core-collapse supernovae. NGC 4501 sits in the southern part of a cluster of galaxies known as the Ursa Major I Cluster. This cluster is especially rich in spirals such as NGC 4051, and is a subset of the larger Virgo Supercluster, which also houses the Milky Way. For more information, follow the link in our bio.

#HubbleFriday This striking image was taken by Hubble’s Wide Field Camera 3 (WFC3), a powerful instrument installed on the telescope in 2009. WFC3 is responsible for many of Hubble’s most breathtaking and iconic photographs. Shown here, NGC 7773 is a beautiful example of a barred spiral galaxy. A luminous bar-shaped structure cuts prominently through the galaxy's bright core, extending to the inner boundary of NGC 7773's sweeping, pinwheel-like spiral arms. Astronomers think that these bar structures emerge later in the lifetime of a galaxy, as star-forming material makes its way towards the galactic center — younger spirals do not feature barred structures as often as older spirals do, suggesting that bars are a sign of galactic maturity. They are also thought to act as stellar nurseries, as they gleam brightly with copious numbers of youthful stars. Our galaxy, the Milky Way, is thought to be a barred spiral like NGC 7773. By studying galactic specimens such as NGC 7773 throughout the universe, researchers hope to learn more about the processes that have shaped — and continue to shape — our cosmic home.

#HubbleFriday This luminous orb is the galaxy NGC 4621, better known as Messier 59. As this latter moniker indicates, the galaxy is listed in the famous catalog of deep-sky objects compiled by French comet-hunter Charles Messier in the 18th century. However, German astronomer Johann Gottfried Koehler is credited with discovering the galaxy just days before Messier added it to his collection in 1779. Modern observations show that Messier 59 is an elliptical galaxy, one of the three main kinds of galaxies along with spirals and irregulars. Ellipticals tend to be the most evolved of the trio, full of old, red stars and exhibiting little or no new star formation. Messier 59, however, bucks this trend somewhat; the galaxy does show signs of star formation, with some newborn stars residing within a disk near the core. Located in the 2,000-strong Virgo cluster of galaxies within the constellation of Virgo (the Virgin), Messier 59 lies approximately 50 million light-years away from us.

#HubbleClassic Two spiral galaxies are seen passing by each other like majestic ships in the night in this Hubble image. The larger and more massive galaxy on the left is cataloged as NGC 2207 and the smaller one on the right is IC 2163. Strong tidal forces from NGC 2207 have distorted the shape of IC 2163, flinging out stars and gas into long streamers stretching out a hundred thousand light-years toward the right-hand edge of the image. Calculations indicate that IC 2163 is swinging past NGC 2207, having made its closest approach 40 million years ago. However, IC 2163 does not have sufficient energy to escape from the gravitational pull of NGC 2207, and is destined to be pulled back and swing past the larger galaxy again in the future. Trapped in their shrinking, mutual orbit, these two galaxies will continue to distort and disrupt each other. Eventually, billions of years from now, they will merge into a single, more massive galaxy. It is believed that many present-day galaxies, including the Milky Way, were assembled from a similar process.

#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.
