Taurus Molecular Cloud - Taurus Molecular Cloud - This region is located on the border of the Taurus and Persee constellations. Covering about 20 x 30 degres, this image shows a complex of emitted nebulae, star clusters, reflexion nebulae and dark nebulae. A molecular cloud is a region of dense gas and dust composed mainly of molecular hydrogen and helium. It's a birthplace of stars. The Molecular Cloud of Taurus is located about 400 years ago - light, and is one of the closest molecular clouds to our solar system. The California Nebula (NGC 1499), an emission nebula located about 1000 years ago - is visible at the top right. The dark nebulae B7, B18 and B19 are visible near the center of the image. Les Pleiades, M45, is the open cluster at the bottom right center. The open clusters NGC 1817, NGC 1746, NGC 1647 are on the left side of the image. The Hyades, Melotte 25, is a V-shaped cluster at the bottom left. It is the closest open cluster, located at a distance of about 151 light yea

Remnants of Supernova of Vails - detail - Pencil Nebula (NGC 2376) - Remnants from a star that exploded thousands of years ago created a celestial abstract portrait, as captured in this image of the Pencil Nebula. Officially known as NGC 2736, the Pencil Nebula is part of the huge Vela supernova remnant, located in the southern constellation Vela. Discovered by Sir John Herschel in the 1840s, the nebula's linear appearance triggered its popular name. The nebula's shape suggests that it is part of the supernova shock wave that recently encountered a region of dense gas. It is this interaction that causes the nebula to glow, appearing like a rippled sheet. In this snapshot, astronomers are looking along the edge of the undulating sheet of gas. This view shows large, wispy filamentary structures, smaller bright knots of gas, and patches of diffuse gas. The Hubble Heritage Team used the Advanced Camera for Surveys in October 2002 to observe the nebula. The region of the Pencil Nebula captu

Detail of nebula NGC 3372 in Carene - Eta Carinae nebula detail - Detail of nebula NGC 3372 in the constellation Carene. Within the dark structures visible in this image, stars will be born. Image obtained by the Hubble Space Telescope in 2005 and 2010. These one - light - year - tall pillars of cold hydrogen and dust, imaged by the Hubble Space Telescope, are located in the Carina Nebula. Violent stellar winds and powerful radiation from massive stars are sculpting the surrounding nebula. Inside the dense structures, new stars may be born. This image of dust pillars in the Carina Nebula is a composite of 2005 observations taken of the region in hydrogen light (light emitted by hydrogen atoms) along with 2010 observations taken in oxygen light (light emitted by oxygen atoms), both times with Hubble's Advanced Camera for Surveys. The immense Carina Nebula is an estimated 7,500 light - years away in the southern constellation Carina

Crab pulsar in nebula M1 - The Crab pulsar: This image from the Hubble space telescope shows the central region of the Crab nebula or resides its pulsar. The pulsar is visible in the center of the image. It is a very dense neutron star from the explosion of a massive supernova star. This star quickly rotates on itself developing a powerful magnetic field, emitting beams of light and radio waves. M1 is located about 6000 light-years in the constellation Taurus.. While many other images of the famous Crab Nebula have focused on the filaments in the outer part of the nebula, this image shows the very heart of the Crab Nebula including the central neutron star - it is the rightmost of the two bright stars near the centre of this image. The rapid motion of the material nearest to the central star is revealed by the subtle rainbow of colours in this time-lapse image, the rainbow effect being due to the movement of material over the time between one image and another

It is with great pleasure that the Sea - viewing Wide Field - of - view Sensor (SeaWIFS) Project announces that September 18, 2000, was the third anniversary of the start of SeaWIFS observations of this remarkable planet called Earth. This SeaWIFS image of our world depicts the global biosphere - - the ocean's long - term average phytoplankton chlorophyll concentration acquired between September 1997 and August 2000 combined with the SeaWIFS - derived Normalized Difference Vegetation Index over land during July 2000. This image shows where there is more or less plant life on our planet. On land, the dark greens show where there is abundant vegetation and tans show relatively sparse plant cover. In the oceans, red, yellow, and green pixels show dense phytoplankton blooms while blues and purples show where there is very little of the microscopic marine plant

This Giant Galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. Image obtained from the 3.9m telescope of Siding Spring, Australia. Centaurus A is a most unusual galaxy. The circular, uniformly bright portion is composed of several thousand million stars, most of them old and yellowish. The galaxy is girded by a dense dust lane which obscures and reddens the light of stars behind it. Some younger, blue stars can be seen at the edges of the dust cloud. One of the nearer galaxies, 13 million light years away, Centaurus A is the most powerful nearby radio source and is also a copious source of X - and gamma rays as well as visible and infrared radiation

Detail of the horse's head nebula by the VLT - Horsehead Nebula, which is situated in the Orion molecular cloud complex. Its official name is Barnard 33 and it is a dust protrusion in the southern region of the dense dust cloud Lynds 1630, on the edge of the HII region IC 434. The distance to the region is about 1400 light - years (430 pc). This beautiful colour image was produced from three images obtained with the multi - mode FORS2 instrument at the second VLT Unit Telescope (KUEYEN) on February 1, 2000. Three predominant colours are seen in the image: red from the hydrogen (H - alpha) emission from the HII region; brown for the foreground obscuring dust; and blue - green for scattered starlight. The blue - green regions of the Horsehead Nebula correspond to regions not shadowed from the light from the stars in the H II region to the top of the picture and scatter stellar radiation towards the observer; these are thus 'mountains' of dust

Mars is half again further from the Sun than the Earth The vast deserts of North Africa are no match for the planet-wide desert that is Mars. While the Earth is host to oceans of liquid water and has a relatively dense water-rich atmosphere, Mars is exceedingly dry, cold, and so far as we know, sterile. It is believed that Mars lost most of its water to space a long time ago, and any water that remains is frozen at the poles and locked deep in the ground as permafrost. It is an interesting coincidence that the total surface area of Mars is about the same as the surface area of dry land on the Earth

The results are of great interest because they shed new light on the poorly understood ejection of stellar matter which accompanies the slow death of Sun - like stars. According to one theory for the formation of planetary nebulae, the hourglass shape is produced by the expansion of a fast stellar wind within a slowly expanding cloud which is more dense near its equator than near its poles.

This is a large area of emission nebulosity around Sadr, Gamma Cygnii, the brightest star in this photo and the heart of Cygnus. Stretching more than 2 x 3 degrees here, the nebulosity actually extends far out of the photo. Most of the nebulosity is fairly faint, but brighter patches can be seen in a modest instrument. The two sections of nebulosity to the left of Gamma are called the Butterfly Nebula and have the catalog designation of IC 1318. LDN 889 is the large area of dark nebulosity that separates the two halves of the Butterfly Nebula, and B 343 is the small but very dense dark nebula on the right side of the image

Globular cluster Terzan 5 in Sagittarius - Globular cluster Terzan 5 in Sagittarius - The globular cluster Terzan 5 is located in the constellation Sagittarius. Its stars are not all at the same time and show great age differences between 6 and 12 billion years. Image obtained by the Hubble Space Telescope (HST). Deep within the Milky Way lies the ancient globular cluster Terzan 5. This NASA/ESA Hubble Space Telescope image shows the cluster in wonderful detail, but it is the chaotic motions of its stars that make it particularly interesting to astronomers. Terzan 5 has an exceptionally dense core. As a result, it is thought to have one of the highest stellar collision rates for a globular cluster. And packed in at such close quarters, many stars are pushed so close together that they form tight binary systems. Interestingly, studies of individual stars within the cluster reveal that they can be split into two age groups: 6 and 12 billion years old. Some astronomers have hypothesised t

Kepler is the rest of a supernova that exploded about 400 years ago located about 13,000 light years from Earth in the constellation Ophiuchus. This image obtained from the Hubble space telescope shows the filamentous structures of gases heated in contact with the shock wave. Composite of images obtained in August 2003 and May 2004; cumulative poses of 6 hours 30 minutes - Visible-light images from the Hubble telescope's Advanced Camera for Surveys reveal where the supernova shock wave is slamming into the densest regions of surrounding gas. The bright glowing knots are dense clumps from instabilities that form behind the shock wave. The Hubble data also show thin filaments of gas that look like rippled sheets seen edge-on. These filaments reveal where the shock wave is encountering low-density, more uniform interstellar material. Hubble's image was taken with the Advanced Camera for Surveys (ACS) on August 28/29, 2003 & May 26, 2004 for a total of 6.5 hours: Remains of the supernova K

The M16 star cluster is a cluster of young stars formed about 2 million years ago in the Eagle nebula, IC 4703. These stars are much warmer than the Sun and can be 30 times more massive. Image made with Siding Spring's 3.9m telescope. There are few clearer examples anywhere of the intimate relationship between dust, gas and young stars than M16. We see a young cluster of stars (NGC 6611) which formed about 2 million years ago, illuminating a cloud of hydrogen gas. The gas is also dusty, and in places the dust is dense enough to prevent starlight from reaching the gas and making it glow with its distinctive red hue. The luminous hydrogen provides a vivid background against which are seen numerous dark lanes and discrete globules of dust.

Typically the head of the globule faces a hot O - type star. Intense radiation from the star boils away lower density gas from the head. The evaporated rim of gas becomes ionized by the stars ultraviolet flux forming a bright glowing rim we associate with many of these globules including CG4. Intense stellar winds from the ionizing star evaporate gas and dust away from the head forming the “” tail”” and completing the cometary shape. The blood cells are known to be the birthplace of low mass stars. Stars form within the blood cells by the mechanism known as “” radiation driven implosion”. This process occurs when ultraviolet flux from a hot star compresses surviving clumps of cold molecular gas eventually causing collapse

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

Neptune - Illustration - Artist's view of Neptune with its ring system and large dark spot observed by the Voyager 2 probe in 1989. This image suggests how Neptune might look from a position in space above the plane of its rings. Like Uranus, Neptune is a Gas Giant, composed primarily of hydrogen and helium gases surrounding a relatively small, dense core of molten rock and metal. Also like Uranus, Neptune has charcoal - colored rings, although they appear to be fewer in number than Uranus's. While Neptune's diameter is slightly less than Uranus ', it has more mass. Neptune's blue color is due to the presence of methane in its upper atmosphere. The dark spot in the southern hemisphere beneath the rings, dubbed “” The Great Dark Spot,””” is believed to be a giant storm which was active in 1989 when Voyager 2 photographed Neptune. Just beyond the rings at Neptune's 7 o'clock position, barely discernable from the background stars, is the tiny satellite Proteus. With an average diameter of

A Day on Io - 5/6 - Illustration - A Day on Io - 5/6 - Artwork: Io always points the same face towards Jupiter during his orbit and like the Moon from Earth, Jupiter presents different phases to him. This series of images shows the landscape changing in a day from a point in the northern hemisphere of Io-5. Ten and a half hours later, the sun set on the horizon of Io. Jupiter is in his last quarter phase. In the distance, a volcano erupts and the gases emitted into the thin atmosphere of Io illuminate in the magnetic field surrounding Jupiter and Io - Io keeps the same face towards Jupiter as it orbits the planet. For this reason, Jupiter appears to hang motionless in Io's sky. Just as the Earth's Moon does, Jupiter goes through phases as Io orbits it. Here's a gallery showing the view from a location in the northern hemisphere during the course of a single day - 5. Ten and a half hours later and the sun has now set below Io's horizon.

Like Saturn and Jupiter, Uranus is a Gas Giant, composed primarily of hydrogen and helium gases surrounding a relatively small, dense core of molten rock and metal. Its bluish color is due to the presence of methane in its upper atmosphere. Also like Saturn and Jupiter, Uranus has rings.

The Vesuve seen at Radar - 15/04/1994 Mt. Vesuvius, one of the best known volcanoes in the world primarily for the eruption that buried the Roman city of Pompeii, is shown in the center of this radar image. The central cone of Vesuvius is the dark purple feature in the center of the volcano. This cone is surrounded on the northern and eastern sides by the old crater rim, called Mt. Somma. Recent lava flows are the pale yellow areas on the southern and western sides of the cone. Vesuvius is part of a large volcanic zone which includes the Phalagrean Fields, the cluster of craters seen along the left side of the image. The Bay of Naples, on the left side of the image, is separated from the Gulf of Salerno, in the lower left, by the Sorrento Peninsula. Dense urban settlement can be seen around the volcano. The city of Naples is above and to the left of Vesuvius; the seaport of the city can be seen in the top of the bay. Pompeii is located just below the volcano on this image. The rapid er

Planetary nebula M 27 (NGC 6853) in the little fox - This excellent image of the Dumbbell Nebula (M27, NGC6853), a planetary nebula in the constellation of Vulpecula, was taken at the 3.5 - meter WIYN telescope using the mini - mosaic imager. The nebula was formed when an evolved, red giant star ejected its outer envelope near the end of its lifetime. The expanding cloud of gas becomes visible once the hot core of the star, visible near the center, is exposed and the high - energy, ultraviolet light from the core ionizes the cloud. This makes the nebula emit mostly a strong emission - line spectrum. This color image was obtained by combining three separate pictures, each one taken through a narrow filter centered at the emission wavelengths of Hydrogen (H alpha, red, 656 nm), doubly ionized Oxygen (OII, green, 501 nm), and neutral Oxygen (OI, blue, 630 nm). It is physically very interesting that neutral gas can survive in a region right next to highly ionized gas, and this image shows

Some of the coldest and darkest dust in space shines brightly in this infrared image from the Herschel Observatory, a European Space Agency mission with important participation from NASA. The image is a composite of light captured simultaneously by two of Herschel's three instruments - - the photodetector array camera and spectrometer, and its spectral and photometric imaging receiver. The image reveals a cold and turbulent region where material is just beginning to condense into new stars. It is located in the plane of our Milky Way galaxy, 60 degrees from the center.

Spiral galaxy M81 seen by the Hubble space telescope - Spiral galaxy M81 in Ursa Major - The spiral galaxy M81 is located 12 million years ago - light from Earth. Its arms are home to star-forming regions, while its core is surrounded by much older yellow stars and a black hole. Image obtained by the Hubble space telescope with the ACS camera in 2006. Although the M81 galaxy is 11.6 million light - years away, this image taken by the Hubble space telescope is so sharp that it can resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. The spiral arms, which wind all the way down into the nucleus, are made up of young, bluish, hot stars formed in the past few million years. They also host a population of stars formed in an episode of star formation that started about 600 million years ago. The greenish regions are dense areas of bright star formation.

This picture was taken by the Advanced Camera for Surveys (ACS) aboard Nasa's Hubble Space Telescope. The region of the nebula shown in this photograph is about 3,500 times wider than our solar system. The area represents about 60 percent of the total view captured by ACS. The nebula, also called M17 and the Swan Nebula, resides 5,500 light - years away in the constellation Sagittarius. Like its famous cousin in Orion, the Swan Nebula is illuminated by ultraviolet radiation from young, massive stars, located just beyond the upper right corner of the image. Each star is about six times hotter and 30 times more massive than the Sun. The powerful radiation from these stars evaporates and erodes the dense cloud of cold gas within which the stars formed.
