Flying Star Zeta Ophiuchi - Runaway Star Zeta Ophiuchi - The blue star near the center of the image is Zeta Ophiuchi, a very massive star moving at 24 km per second. It is a “” fleeing star”, a star ejected by the explosion of his companion star. In this infrared image obtained by the WISE (Wide - field Infrared Survey Explorer) satellite, the interstellar dust traversed by the star appears, as well as an arc-shaped shock wave caused by the powerful stellar winds that the star breaks. The blue star near the center of this image is Zeta Ophiuchi. When seen in visible light it appears as a relatively dim red star surrounded by other dim stars and no dust. However, in this infrared image taken with Nasa's Wide - field Infrared Survey Explorer, or WISE, a completely different view emerges. Zeta Ophiuchi is actually a very massive, hot, bright blue star plowing its way through a large cloud of interstellar dust and gas. Astronomers theorize that this stellar juggernaut was likely once part of a binary star system with an even more massive partner. It's believed that when the partner exploded as a supernova, blasting away most of its mass, Zeta Ophiuchi was suddenly freed from its partner's pull and shot away like a bullet moving 24 kilometers per second (54,000 miles per hour). Zeta Ophiuchi is about 20 times more massive and 65,000 times more luminous than the sun. If it werenn't surrounded by so much dust, it would be one of the brightest stars in the sky and appear blue to the eye. Like all stars with this kind of extreme mass and power, it subscribes to the 'live fast, die young' motto. It's already about halfway through its very short 8 - million - year lifespan. In comparison, the sun is roughly halfway through its 10 - billion - year lifespan. While the sun will eventually become a quiet white dwarf, Zeta Ophiuchi, like its ex - partner, will ultimately die in a massive explosion called a supernova.

Galaxy of the Wheel of the Charette in the Sculptor - The Cartwheel Galaxy - The ring galaxy of the Wheel of the Charette is about 500 million years away - light from the Earth. It is surrounded by a ring of 150,000 years - light of diameter composed of young and very bright stars. This particular form is the result of a collision, probably with one of the two galaxies on the right. Image obtained by the Hubble Space Telescope in October 1994. A rare and spectacular head - on collision between two galaxies appears in this NASA Hubble Space Telescope true - color image of the Cartwheel Galaxy, located 500 million light - years away in the constellation Sculptor. The details of star birth resolved by Hubble provide an opportunity to study how extremely massive stars are born in large fragmented gas clouds. The striking ring - like feature is a direct result of a smaller intruder galaxy - - possibly one of two objects to the right of the ring - - that careened through the core of the host galaxy. Like a rock tossed into a lake, the collision sent a ripple of energy into space, plowing gas and dust in front of it. Expanding at 200,000 miles per hour, this cosmic tsunami leaves in its wake a firestorm of new star creation. Hubble resolves bright blue knots that are gigantic clusters of newborn stars and immense loops and bubbles blown into space by exploding stars (supernovae) going off like a string of firecrackers. The Cartwheel Galaxy presumably was a normal spiral galaxy like our Milky Way before the collision.

The Rosette Nebula in the Unicorn - The Rosette Nebula and NGC 2244 cluster - The Rosette Nebula is a vast cloud of dust and gas located about 5500 years from Earth. Towards the center of the nebula, a cluster of blue stars, NGC 2244 formed less than a million years ago. Image obtained by Siding Spring's 3.9m telescope. In the hollowed - out centre of the Rosette nebula lies NGC 2244, the cluster of young stars recently formed there. The cluster has itself created the cavity, radiation pressure and stellar winds from the stars blowing the gas and dust away from the young cluster. The hottest (and brightest) members of the group are seen as distinctly blue on this photograph, a colour corresponding to a surface temperature around 20,000K which may be compared with the Sun's 5500K. The nebula and its cluster is at a distance of about 4500 light years and shows many streaks and globules of dust, remnants of the cloud from which the stars formed

Hertzsprung - Russell - The Hertzsprung - Russell diagram - HR diagram (Hertzsprung - Russell) displaying stars according to their surface temperature and luminosite. The Hertzsprung - Russell diagram is named after the Danish astronomer Einar Hertzsprung (1873 - 1967) and the American astronomer Henry Norris Russell (1877 - 1957). At the beginning of the 20th century they independently noticed that red stars come in very different sizes, pioneering subsequent studies of stellar parameters (e.g., temperature, size and mass). In its basic version, this diagram plots stellar temperature (or colour) against brightness (or magnitude) and is therefore also referred to as the “” colour - magnitude diagram””. The position of a particular star in the diagram also provides information about its evolutionary stage (and age)

Globular cluster M5 in Serpens - Globular cluster M5 in Serpens - This cluster of stars is located about 25,000 light years away from Earth. It is one of the most extensive (165 years - light) and one of the oldest known globular clusters. Globular clusters are generally peoples of very old stars, but here the Hubble space telescope has identified some young stars, blue stragglers. The globular cluster Messier 5, shown here in this NASA/ESA Hubble Space Telescope image, is one of the oldest belonging to the Milky Way. The majority of its stars formed more than 12 billion years ago, but there are some unexpected newcomers on the scene, adding some vitality to this aging population. Stars in globular clusters form in the same stellar nursery and grow old together. The most massive stars age quickly, exhausting their fuel supply in less than a million years, and end their lives in spectacular supernovae explosions. This process should have left the ancient cluster Messier 5 with only old, low - mass stars, which, as they have aged and cooled, have become red giants, while the oldest stars have evolved even further into blue horizontal branch stars. Yet astronomers have spotted many young, blue stars in this cluster, hiding among the much more luminous ancient stars. Astronomers think that these laggard youngsters, called blue stragglers, were created either by stellar collisions or by the transfer of mass between binary stars. Such events are easy to imagine in densely populated globular clusters, in which up to a few million stars are tightly packed together. Messier 5 lies at a distance of about 25 000 light - years in the constellation of Serpens (The Snake).

Constellation of the Great Dog - Constellation of Canis Major - Sirius, the bright star on this image is the brightest star in the sky. Canis Major (the Greater Dog) is one of two dogs accompanying Orion the hunter across the sky. The other is Canis Minor. The constellation figure is ancient, and was one of 48 constellations mentioned by Ptolemy (83 - 161 AD), no doubt reflecting earlier ideas. The modern stick figure joining the brightest stars (above) certainly has a very doggy appearance. The brightest star in the sky is here, Sirius, the Dog Star, so called because its emanations were thought to affect dogs in the heat of summer, the 'Dog Days' when the star is in the same part of the sky as the Sun. Sirius is bright because it is only 8.6 light years from the Sun and it is in any case it is an intrinsically bright star, 25 times more luminous than the Sun

Galaxy AM 0644 - 741 in Flying Fish - Ring galaxy AM 0644 - 741 in Volans - The annular galaxy AM 0644 - 741 is about 300 million years away - light from Earth. A collision with another galaxy causes its ring shape. This ring extends over 150,000 years - light and is composed of recently formed and extremely bright blue stars. Image obtained by the Hubble Space Telescope in January 2004. This galaxy, cataloged as AM 0644 - 741, is a member of the class of so - called “” ring galaxies.”” It lies 300 million light - years away in the direction of the southern constellation Volans. Ring galaxies are an especially striking example of how collisions between galaxies can dramatically change their structure, while also triggering the formation of new stars. In the case of AM 0644 - 741, the galaxy that pierced through the ring galaxy is out of the image but visible in larger - field images. The soft spiral galaxy that is visible to the left of the ring galaxy in the image is a coincidental background galaxy that is not interacting with the ring. The resulting gravitational shock imparted due to the collision drastically changes the orbits of stars and gas in the target galaxy's disk, causing them to rush outward, somewhat like ripples in a pond after a large rock has been thrown in. As the ring plows outward into its surroundings, gas clouds collide and are compressed. The clouds can then contract under their own gravity, collapse, and form an abundance of new stars. The rampant star formation explains why the ring is so blue: It is continuously forming massive, young, hot stars, which are blue in color. Another sign of robust star formation is the pink regions along the ring. These are rarefied clouds of glowing hydrogen gas, fluorescing because of the strong ultraviolet light from the newly formed massive stars — Galaxy AM 0644 - 741 in Flying Fish - Ring galaxy AM 0644 - 741 in Volans - The annular galaxy AM 0644 - 741 is about 300 million years away - light from Earth.

Galaxy UGC 10214 in the Dragon - Galaxy UGC 10214 in Draco - The galaxy UGC 10214 is about 420 million years away - light from Earth. The shape of this galaxy is due to a collision with another galaxy, the small galaxy, blue, visible in the upper left corner of the image. Powerful gravitational forces are responsible for the formation of the tail, consisting of stars of dust and gas, which stretches over nearly 28,000 light years and is composed of recently formed and extremely bright blue stars. In the background, more than 6000 galaxies are visible, some more than 12 billion years apart - light. Image obtained by the Hubble Space Telescope in April 2002. This picture of the galaxy UGC 10214 was taken by the Advanced Camera for Surveys (ACS), which was installed aboard Nasa's Hubble Space Telescope in March during Servicing Mission 3B. Its distorted shape was caused by a small interloper, a very blue, compact galaxy visible in the upper left corner of the more massive Tadpole. The Tadpole resides about 420 million light - years away in the constellation Draco. Seen shining through the Tadpole's disk, the tiny intruder is likely a hit - and - run galaxy that is now leaving the scene of the accident. Strong gravitational forces from the interaction created the long tail of debris, consisting of stars and gas that stretch out more than 280,000 light - years. Numerous young blue stars and star clusters, spawned by the galaxy collision, are seen in the spiral arms, as well as in the long “” tidal”” tail of stars. Each of these clusters represents the formation of up to about a million stars. Their color is blue because they contain very massive stars, which are 10 times hotter and 1 million times brighter than our Sun. Once formed, the star clusters become redder with age as the most massive and bluest stars exhaust their fuel and burn out. These clusters will eventually become old globula — Galaxy UGC 10214 in the Dragon - Galaxy UGC 10214 in Draco - The galaxy UGC 10214 is about 420 million years away - light from Earth.

Image obtained by the Hubble Space Telescope in October 1994. A rare and spectacular head - on collision between two galaxies appears in this NASA Hubble Space Telescope true - color image of the Cartwheel Galaxy, located 500 million light - years away in the constellation Sculptor. The details of star birth resolved by Hubble provide an opportunity to study how extremely massive stars are born in large fragmented gas clouds. The striking ring - like feature is a direct result of a smaller intruder galaxy - - possibly one of two objects to the right of the ring - - that careened through the core of the host galaxy. Like a rock tossed into a lake, the collision sent a ripple of energy into space, plowing gas and dust in front of it. Expanding at 200,000 miles per hour, this cosmic tsunami leaves in its wake a firestorm of new star creation. Hubble resolves bright blue knots that are gigantic clusters of newborn stars and immense loops and bubbles blown into space by exploding stars (supernovae) going off like a string of firecrackers. The Cartwheel Galaxy presumably was a normal spiral galaxy like our Milky Way before the collision. This spiral structure is beginning to re - emerge, as seen in the faint arms or spokes between the outer ring and bulls - eye shaped nucleus.

Bok's cells in NGC 281 (Cassiopee) - Bok globules in NGC 281 - View of a detail of the nebula NGC 281 in Cassiopee center on Bok's Globules. A Bok's blood cell is a dark interstellar cloud of gases and dust that absorb light. If it condenses enough, it gives birth to new stars. Near these blood cells shine blue stars; they belong to the young cluster of stars IC 1590. Image obtained by the Hubble Space Telescope in October 2005. These opaque, dark knots of gas and dust are called “” Bok globules,””” and they are absorbing light in the center of the nearby emission nebula and star - forming region. Bok hypothesized that giant molecular clouds, on the order of hundreds of light - years in size, can become perturbed and form small pockets where the dust and gas are highly concentrated. These small pockets become gravitationally bound and accumulate dust and gas from the surrounding area. If they can capture enough mass, they have the potential of creating stars in their cores; however, not all Bok globules will form stars. Some will dissipate before they can collapse to form stars. That may be what's happening to the globules seen here in NGC 281. Near the globules are bright blue stars, members of the young open cluster IC 1590. The cluster is made up of a few hundred stars. The club's core, off the image towards the top, is a tight grouping of extremely hot, massive stars with an immense stellar wind. The stars emit visible and ultraviolet light that energizes the surrounding hydrogen gas in NGC 281. This gas then becomes super heated in a process called ionization, and it glows pink in the image. The Bok globules in NGC 281 are located very close to the center of the IC 1590 cluster. The heavy fracturing of the globules may appear beautifully serene but is in fact evident of the harsh — Bok's cells in NGC 281 (Cassiopee) - Bok globules in NGC 281 - View of a detail of the nebula NGC 281 in Cassiopee center on Bok's Globules.

Open cluster NGC 2244 in the nebula of the Rosette - The Rosette Nebula and NGC 2244 cluster - The Rosette nebula is a vast cloud of dust and gas situated about 5500 years away from Earth. Towards the center of the nebula, a cluster of blue stars, NGC 2244 formed less than a million years ago. Image obtained by Siding Spring's 3.9m telescope. In the hollowed - out centre of the Rosette nebula lies NGC 2244, the cluster of young stars recently formed there. The cluster has itself created the cavity, radiation pressure and stellar winds from the stars blowing the gas and dust away from the young cluster. The hottest (and brightest) members of the group are seen as distinctly blue on this photograph, a colour corresponding to a surface temperature around 20,000K which may be compared with the Sun's 5500K. The nebula and its cluster is at a distance of about 4500 light years and shows many streaks and globules of dust, remnants of the cloud from which the stars formed

Orion Constellation - Constellation of Orion - Orion the Hunter is one of the most familar and best known constellations. There is extensive and varied mythology about this beautiful collection of stars, but the most common Greek legend has Orion as a giant huntsman, and he appears in this role in Homer's Odyssey. The most persistent legend seems to be that he died from the sting of a giant scorpion, which was placed in the sky so that Orion sets as the Scorpius rises, in an eternal chase across the sky. The momorable outline of the Hunter proudly bestrides the celestial equator and is equally visible from both hemispheres. The distinctive, equally spaced line of stars of Orion's Belt are more or less on the equator and are framed by quartet of bright and colourful stars. More subtle is Orions short sword, hanging from his belt. Under dark skies or in binoculars the central 'star' is distinctly misty. This is the famous Orion nebula, one of many well known telescopic objects that fill this part of the sky. The westernmost Orion Belt star delta Orionis (Minkata) is about a quarter of a degree of arc south of the celestial equator and all three belt stars are within 2 degrees of it. This means they rise and set due east or west of the observer and track the equator across the sky during the night, tracing straight lines in star trail photographs.

This Hubble Space Telescope view of the core of one of the nearest globular star clusters, called NGC 6397, located 8,200 light - years away in the constellation Ara. The stellar density is about a million times greater than in our Sun's stellar neighborhood. The stars are only a few light - weeks apart, while the nearest star to our Sun is over four light - years away. The ancient stars are so crowded together that a few of them inevitably collide with each other once in a while. Near misses are even more common. Even so, collisions only occur every few million years or so. When direct collisions occur, the two stars may merge to form a new star called a “” blue straggler”””; these hot, bright, young stars stand out among the old stars that make up the vast majority of stars in a globular cluster. Several such bright blue stars are visible near the center of the cluster in the image.

Nebula of the Lagoon (M8) in Sagittarius - The Lagoon nebula (M8) in Sagittarius - View of the Nebula of the Lagoon (M8/NGC 6523). Located in Sagittarius, at a distance of 5800 years - light, it is visible to the naked eye in good conditions. It is a star-forming region illuminated by several large O-type stars that belong to the open cluster NGC 6530 visible in the center of the image. The brightest part of the nebula is called the hourglass nebula whose gases are excited mainly by two massive supergeant stars Herschel 36 and 9 Sagittarii. M8 has at least 60 Giant B stars, 3 to 4 times more than the Orion Nebula. The Lagoon nebula (M8), can be visible to the unaided eye as a small bright patch above the large Sagittarius star cloud in the Milky Way. The Lagoon nebula is a star - forming region about 5800 light years from us. The nebula is illuminated by several O - type giants within the open cluster NGC 6530 near the center of the nebula. The brightest part of the nebula is known as the “hourglass nebula”” and its gases are excited primarily by two massive O - type supergiants designated Herschel 36 and 9 Sagittarii. These two stars lie to the west of NGC 6530 and are separated from it by a dark lane dividing the nebula like a black lagoon, giving it its name.

Canis Major (the Greater Dog) is one of two dogs accompanying Orion the hunter across the sky. The other is Canis Minor. The constellation figure is ancient, and was one of 48 constellations mentioned by Ptolemy (83 - 161 AD), no doubt reflecting earlier ideas. The modern stick figure joining the brightest stars (above) certainly has a very doggy appearance. The brightest star in the sky is here, Sirius, the Dog Star, so called because its emanations were thought to affect dogs in the heat of summer, the 'Dog Days' when the star is in the same part of the sky as the Sun.

Blue stragglers in cluster 47 Toucan - Blue stragglers in globular cluster 47 Tucanae - This image obtained by the Hubble space telescope shows a detail of the 47 Toucan cluster near its center (the field is indicated on the left image taken from the ground). The yellow circles on the right image indicate the position of stars identified by the telescope as blue trainers. Because of the high density of stars within a globular cluster, a collision between two stars sometimes occurs, merging into a single young, bright and warm star called a blue straggler. The core of globular cluster 47 Tucanae is home to many blue stragglers, rejuvenated stars that glow with the blue light of young stars. A ground - based telescope image (on the left) shows the entire crowded core of 47 Tucanae, located 15,000 light - years away in the constellation Tucana. Peering into the heart of the globular cluster's bright core, the Hubble Space Telescope's Wide Field and Planetary Camera 2 separated the dense clump of stars into many individual stars (image on right). Some of these stars shine with the light of old stars; others with the blue light of blue stragglers. The yellow circles in the Hubble telescope image highlight several of the club's blue stragglers. Astronomers theorize that blue stragglers are formed either by the slow merger of stars in a double - star system or by the collision of two unrelated stars. For the blue straggler in 47 Tucanae, astronomers favor the slow merger scenario. This photo is a three - color composite of Wide Field and Planetary Camera 2 archival images taken with ultraviolet, blue, and violet filters. Green, blue, and red colors were assigned to the filters and scaled so that the red giant stars appear orange, the main sequence stars are white/green, and the blue stragglers are appropriately blue.

Open cluster NGC 4755 - Jewel box - The Jewel Box cluster - The NGC 4755 cluster is located in the constellation of the Southern Cross at a distance of 7800 years - light from Earth. The bright orange star is Kappa Crucis, a supergiant red star. This cluster contains about fifty stars formed about 14 million years ago. NGC4755 (Caldwell 94) is called the Jewel Box, based on John Herschel's comment in the 1830's that it looked like a superb piece of jewelry. There are about 50 stars in this cluster which formed some 14 million years ago. Most of the cluster members are blue giants which in a few million years will exhaust their hydrogen fuel and become red giants on their way to a cataclysmic end as supernovae. One red giant can already be seen at the center of the cluster

Open cluster NGC 4755 - Jewel Box - The Jewel Box star cluster - The NGC 4755 cluster is located in the constellation of the Southern Cross at a distance of 6400 years - light from Earth. The bright orange star on the top right is Kappa Crucis, a supergiant red star. This cluster contains about fifty stars formed about 16 million years ago. This close-up of the center of the cluster was obtained with the Hubble Space Telescope. This image is a “” close - up 'view from the NASA/ESA Hubble Space Telescope of NGC 4755, or the Jewel Box cluster. Several very bright, pale blue supergiant stars, a solitary ruby - red supergiant and a variety of other brilliantly coloured stars are visible in the image, as well as many much fainter ones, often with intriguing colours. The huge variety in brightness exists because the brighter stars are 15 to 20 times the mass of the Sun, while the dimmest stars are less than half the mass of the Sun. This is the first image of an open galactic cluster with imaging extending from the far ultraviolet to the near - infrared.

Evolution of a giant blue star - Artist view - Death of a blue giant star - Artist view - Vue d'artiste de la mort d'une supergeante. After several million years of existence, the blue giant star (on the left) swell to become a red supergeante; its heart contracts and its weight heats, resulting in the evaporation of the outer layers of the star (in the centre). When the nucleus is empty of its energy, it compresses itself causing the explosion of the star (a supernova, on the right). This image shows steps in a celestial cataclysm. After several million years, a blue giant star (at left) is becoming a red supergiant (center). As the nuclear reaction within a giant star's core falters, the core collapses, triggering an intensely energetic rebound and the star explodes (a supernova, at right)
