Galaxy UGC 9618 in Bovier - Galaxy UGC 9618 in Botes - The galaxy UGC 9618, also called VV 340 or Arp 302, is about 450 million years away from Earth. It is a pair of interacting spiral galaxies, VV 340A (view from the edge, bottom) and VV 340B (view from the front, top). Massive stars are formed in abundance. Image obtained by the Hubble Space Telescope in January 2002. UGC 9618, also known as VV 340 or Arp 302 consists of a pair of very gas - rich spiral galaxies in their early stages of interaction: VV 340A is seen edge - on to the left, and VV 340B face - on to the right. An enormous amount of infrared light is radiated by the gas from massive stars that are forming at a rate similar to the most vigorous giant star - forming regions in our own Milky Way. UGC 9618 is 450 million light - years away from Earth, and is the 302nd galaxy in ARP's Atlas of Peculiar Galaxies

Hertzsprung - Russell - The Hertzsprung - Russell diagram - Hertzsprung - Russell (HR) diagram 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)

Nebula in the galaxy NGC 6822 - Bubble nebulae in NGC 6822 - Nebula in the irregular galaxy NGC 6822, adjacent to our galaxy. This gas bubble houses massive stars known as Wolf - Rayet. NGC 6822 is a nearby irregular galaxy reminiscent of the Large Magellanic Cloud (LMC). Like the LMC it contains many, extremely hot stars of the Wolf - Rayet type, stars which often have intense stellar winds blasting from their surfaces. Small groups of such stars are found at the centres of the bubble nebulae seen here, which are the result of the stellar winds colliding with the more or less stationary interstellar medium in NGC 6822. At the interface of the collision, the interstellar medium glows, producing a thin, luminous bubble. Such bubbles are rare in the more turbulent Milky Way galaxy, but Henize 70 in the Large Magellanic Cloud is similar

Image obtained by the Hubble Space Telescope (HST) - This shot from the NASA/ESA Hubble Space Telescope shows a maelstrom of glowing gas and dark dust within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud (LMC). This stormy scene shows a stellar nursery known as N159, an HII region over 150 light-years across. N159 contains many hot young stars. These stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which are carving out ridges, arcs, and filaments from the surrounding material. At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star form

Cocoon Nebula (IC 5146) in the Swan - Cocoon Nebula (IC 5146) in Cygnus - The Cocon Nebula, IC 5146, is an emission nebula located about 4000 years from Earth in the constellation of Swan. This star-forming region is illuminated by massive young stars. This complex mass of molecular hydrogen and dust, located 4,000 light years from earth, glows red by emitting light, shines blue by reflecting light and exhibits a pattern of dark lanes that result when dust absorbs light. Much of the light seen in the main part of this nebula is generated by the massive bright star near it's center. The Cocoon is a stellar nursery containing a relatively young open cluster of stars with several individual constituents that are newly formed

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.

It is 75,000 years long - light years long and its shape suggests that it is subject to the gravitational influence of another galaxy yet unidentified. NGC 908 is a starburst galaxy, one that is undergoing a period of intense star formation. This is why it has numerous clumps of bright stars in its spiral arms and appears so bright on this photograph. It is also asymmetrical, with a peculiar split in the spiral arm on the left (eastern) side of the galaxy. Both these characteristics usually mean the galaxy has been disturbed by some massive intruder, usually another galaxy, but none is evident on the photograph or in the wider field around NGC 908

Orion nebula centre - Trapeze - Orion nebula center - Mosaic of images obtained by the space telescope in 1994 and 1995 showing the center of Orion nebula, the region around the Trapeze, a cluster of 4 very young and massive stars that make this nebula shine. The picture shows a churning turbulent star factory set within a maelstrom of flowing, luminescent gas. Although this 2.5 light - years wide view is still a small portion of the entire Orion nebula, it includes almost all of the light from the bright glowing clouds of gas and a star cluster associated with the nebula. Hubble reveals details as small as 4.1 billion miles across. Hubble Space Telescope observing time was devoted to making this panorama because the nebula is a vast laboratory for studying the processes which gave birth to our own Sun and solar system 4.5 billion years ago.

Blue stars can be seen scattered across the frame, set against a distant backdrop of red-hued cosmic companions. This blue litter most likely formed at the same time from the same collapsing molecular cloud. The colour of a star can reveal many of its secrets. Shades of red indicate a star much cooler than the Sun, so either at the end of its life, or much less massive. These low-mass stars are called red dwarfs and are thought to be the most common type of star within the Milky Way. Similarly, brilliant blue hues indicate hot, young, or massive stars, many times the mass of the Sun. A star's mass decides its fate; more massive stars burn brightly over a short lifesp

Nebula of the Lagoon (M8) in Sagittarius - The Hourglass Nebula in M8, NGC 6523 - 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 on the left 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. At the heart of the Lagoon Nebula in Sagittarius lies the diminutive Hourglass Nebula. This extremely bright object is associated with the blue star alongside it, named Herschel 36 after its discoverer. Herschel described M8 as 'A noble nebula' and 'a fine and complicated nebula', but he was clearly intrigued by the Hourglass which he compared to the nucleus of the Andromeda nebula, M31 as 'decidedly not stellar'.

Deep images reveal that the nebula is about a degree across in the sky. At a distance of about 5500 light-years away it is a truly vast structure spanning almost 100 light-years across. The sculpted gases of NGC 6334 are illuminated by the light of numerous powerful stars, some exceeding 10 solar masses. The two brilliant blue stars in the upper left are Lambda and Kappa Scorpii. Many of these luminous hot stars are surprisingly not visible because they lie within the dusty plane of our galaxy. At infrared wavelengths the numerous hot stars are revealed and the nature of this object as a region of massive star formation becomes clear.

Open cluster NGC 3293 in Carene - Open star cluster NGC 3293 in Carina - Star cluster located in the constellation Carene about 8500 years ago - light from Earth. Unlike the Sun, many stars are found in brilliant clusters such as NGC 3293 where they spend their lives. At birth, which should have been at much the same time for all the stars in NGC 3293, the most massive stars are hot and very luminous and therefore appear as the brightest blue stars. With time they deplete their supplies of nuclear fuel, hydrogen. This evolutionary process involves cooling, so that the stars become redder, and would ordinarily disappear from view, but they also swell to gigantic proportions and so remain visible. The bright orange star in NGC 3293 is the member of the cluster which has aged fastest. This cluster is in the constellation of Carina at a distance of about 8500 light years
