Neptune - Voyager 2 - Neptune has an equatorial diameter of about 49,000 kilometres. Its blue color is due to the abundance of methane in its atmosphere. On this photo, on the left, the Great Dark Spot, which is the size of the Earth where winds are blowing at 300 m/s. This spot has now disappeared but other dark spots have been detected since then. Image of Neptune obtained by the Voyager 2 probe on August 16, 1989. During August 16 and 17, 1989, the Voyager 2 narrow - angle camera was used to photograph Neptune almost continuously, recording approximately two and one - half rotations of the planet. These images represent the most complete set of full disk Neptune images that the spacecraft will acquire. This picture from the sequence shows two of the four cloud features which have been tracked by the Voyager cameras during the past two months. The large dark oval near the western limb (the left edge) is at a latitude of 22 degrees south and circuits Neptune every 18.3 hours. The brig

James Webb Space Telescope Mirrors (JWST) - Testing of the JWST's mirrors - Six of the 18 JWST (James Webb Space Telescope) mirrors seen at Nasa's Marshall Space Center. These mirrors will be tested there to ensure they will withstand the extreme temperatures of space vacuum. The JWST will replace the Hubble Space Telescope in 2014. Equipped with a 6.5 m mirror, he will observe the universe mainly in infrared. Six of the 18 James Webb Space Telescope mirror segments are being moved into the X - ray and Cryogenic Facility, or XRCF, at Nasa's Marshall Space Flight Center in Huntsville, Ala., to eventually experience temperatures dipping to a chilling - 414 degrees Fahrenheit to ensure they can withstand the extreme space environments. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures. Marshall's X - ray & Cryogenic Facility is the world's largest X - ray telescope test facility and a unique, cryogenic, clean room optical test location. The

This cluster houses a star that was thought to be the most massive star in our galaxy, between 200 and 300 solar masses (the brightest star in the top center of the image). The measurements obtained by the Hubble telescope showed that this star, Pismis 24 - 1, was actually a double star and that its mass was actually only about 100 solar masses. The small open star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 in Scorpius, about 8,000 light - years away from Earth. Some of the stars in this cluster are extremely massive and emit intense ultraviolet radiation. The brightest object in the picture is designated Pismis 24 - 1.

In February 2015 the unmanned Dawn spacecraft is scheduled to arrive at the dwarf planet Ceres. The 65 foot long, 2.5 ton probe was launched from the Earth in 2007, passed March in 2009, and went into orbit around the protoplanet Vesta in July 2011 where it stayed until September 2012. Once in orbit around Ceres, Dawn is expected to operate for about a year making observations of this largest object in the asteroid belt. In this image Dawn's three xenon electrostatic ion thrusters can be seen emitting ionized xenon's characteristic blue/magenta glow, gently propelling the probe toward Ceres. While the ion engines have relatively low specific thrust (about equal to the weight of a few sheets of paper), they can operate continuously for long periods making efficient use of the approximately 1,000 pounds of xenon propellant onboard.

Suns are born from vast clouds of dust and gas that gather in the dark places between the stars. Gravity causes these interstellar vapors to collapse inward until the pressure causes high enough temperatures at its center to fuse hydrogen, the university's basic building block, into helium - an event that also releases gamma - ray photons. These photons can take a million years to travel outward through the overlying matter until they reach the surface and escape into space as visible light.

Supernova 1987A in the Great Magellan Cloud View by HST - This Hubble Space Telescope picture shows Supernova 1987A and its neighborhood. The series of four panels shows the evolution of the SN 1987A debris from February 1994 to February 1996. Material from the stellar interior was ejected into space during the supernova explosion in February 1987. The explosion debris is expanding at nearly 6 million miles per hour. Ten years now after the explosion, this cosmic fireball is large enough - - - about one - sixth of a light - year in diameter - - - to be resolved from the Earth's orbit with the Hubble Space Telescope. The debris is resolved into two opposing blobs and is dim in the center. The apparent direction of ejection is the same as the short axis of the bright inner ring that surrounds the supernova. This suggests that the explosion is directed out of the plane of the ring. The ring is probably composed of materials lost by the pre - supernova star in the last stages of its evolut

Material from the stellar interior was ejected into space during the supernova explosion in February 1987. The explosion debris is expanding at nearly 6 million miles per hour. Ten years now after the explosion, this cosmic fireball is large enough - - - about one - sixth of a light - year in diameter - - - to be resolved from the Earth's orbit with the Hubble Space Telescope. The debris is resolved into two opposing blobs and is dim in the center. The apparent direction of ejection is the same as the short axis of the bright inner ring that surrounds the supernova. This suggests that the explosion is directed out of the plane of the ring. The ring is probably composed of materials lost by the pre - supernova star in the last stages of its evolut

Planetary nebula NGC 7027 in the Swan/HST - This NASA Hubble Space Telescope image of planetary nebula NGC 7027 shows remarkable new details of the process by which a star like the Sun dies. New features include: faint, blue, concentric shells surrounding the nebula; an extensive network of red dust clouds throughout the bright inner region; and the hot central white dwarf, visible as a white dot at the center. The nebula is a record of the star's final death throes. Initially the ejection of the star's outer layers, when it was at its red giant stage of evolution, occurred at a low rate and was spherical. The Hubble photo reveals that the initial ejections occurred episodically to produce the concentric shells. This culminated in a vigorous ejection of all of the remaining outer layers, which produced the bright inner regions. At this later stage the ejection was non - spherical, and dense clouds of dust condensed from the ejected material. NGC 7027 is located about 3,000 light - year

At the bottom left, the nebula NGC 2024 with just above the star Alnitak, a supergiant star belonging to the Baudrier of Orion. Towards the center of the image, a reflexion nebula, NGC 2023. Image obtained with the 1.2m Schmidt UK Telescope from Siding Spring. This distinctive red emission nebula (IC 434) is the result of radiation from sigma Orionis interacting with the surface of a dusty cloud of gas from which projects the dark shape of the head of a horse. Sigma is the second brightest star in the picture and is at about the same distance from the Sun as the nebula. The brightest star here is zeta Orionis, easily visible to the unaided eye as the easternmost star in the line of three which form Orion's Belt. Alnitak (Zeta Orionis) is a supergiant sta

Center of the particular galaxy Arp 220 in the Serpent - Heart of the galaxy Arp 220 - The galaxy Arp 220 (IC 4553) is about 250 million years away - light from Earth. Designee in the 1960s as a particular galaxy, today it is defined as an ultra-aluminous infrared galaxy. The Hubble space telescope photographed its heart in April 1997 in infrared light and discovered that its nucleus had two spiral galaxies colliding. The two nuclei (the two light points in the center) are 1200 light years apart and orbit around each other. This collision caused a tremendous flare of new stars. The Hubble Space Telescope's Near Infrared Camera and Multi - Object Spectrometer (NICMOS) has uncovered a collision between two spiral galaxies in the heart of the peculiar galaxy called Arp 220. The collision has provided the spark for a burst of star formation. The bright, crescent moon - shaped object is a remnant core of one of the colliding galaxies. The core is a cluster of 1 billion stars. The core's hal

This picture is the culmination of a 10 - day - long observation called the Hubble Deep Field South which was carried out in October 1998. This new “” far - look”” complements the original Hubble “” deep field””” taken in late 1995, when Hubble was aimed at a small patch of space near the Big Dipper. The new region is in the constellation Tucana, near the south celestial pole. Hubble's sharp vision allows astronomers to sort galaxy shapes. The image is dom

Dwarf galaxy Holmberg IX in the Great Bear - Dwarf galaxy Holmberg IX in Ursa Major - The dwarf galaxy Holmberg IX is located 12 million years - light from Earth in the constellation of the Great Bear, just above the spiral galaxy M81. Of the 20,000 stars visible on this image obtained by the Hubble space telescope, more than 90% are young stars aged between 10 and 200 million years. The proximity of other galaxies, including M81, is believed to be at the origin of this recent star formation. This loose collection of stars is actually a dwarf irregular galaxy, called Holmberg IX. It resides just off the outer edge of M81, a large spiral galaxy in Ursa Major. This image was taken with Hubble's Advanced Camera for Surveys in early 2006. Holmberg IX is of the so - called Magellanic type of galaxy, as its size and irregularity in structure are similar to the Small Magellanic Cloud, a neighbour to our own Milky Way.

Planetary nebula M57 (NGC 6720) in Lyra - The Ring nebula (M57) in Lyra - The planetary nebula of Lyra (M57) is located about 2000 years - light from Earth. With a magnitude of 9.0, this nebula is easily observed with a small telescope. A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its matter. The Ring Nebula, M57, is the most famous example of a planetary nebula. Located about 2,000 light years away, it has an apparent diameter of 1 arc minute and a real diameter of about one light year. At magnitude 9.0 its high surface brightness makes it an easy object, even from the city and even with small telescopes. Despite their name, planetary nebulae have nothing to do with planets. They were named originally because their discoverers observed them visually and they did not appear as stellar point sources, but rather as small diffuse objects that resembled the outer planets in our solar system such

M87 elliptical galaxy in Virgo - M87 elliptical galaxy in Virgo - The M87 galaxy (NGC 4486) is 54 million years ago - light from Earth, in the heart of the Virgin's cluster. This composite image obtained by the Hubble space telescope in 2003 and 2006 shows a gigantic jet of gas material ejected from the heart of the galaxy. A supermassive black hole would have caused this jet. The monstrous elliptical galaxy M87 is the home of several trillion stars, a supermassive black hole, and a family of 13,000 globular star clusters. M87 is the dominant galaxy at the center of the neighboring Virgo cluster of galaxies, which contains some 2,000 galaxies. Amid the smooth, yellow population of older stars, the two features that stand out most in this Hubble Space Telescope image of M87 are its soft blue jet and the myriad of starlike globular clusters scattered throughout the image. The jet is a black - hole - powered stream of material that is being ejected from the core of the galaxy. As gaseous

Remains of Supernova N49 dans la Dorade/HST - Resembling the puffs of smoke and sparks from a summer fireworks display in this image from Nasa's Hubble Space Telescope, these delicate filaments are actually sheets of debris from a stellar explosion in a neighboring galaxy. Hubble's target was a supernova remnant within the Large Magellanic Cloud (LMC), a nearby, small companion galaxy to the Milky Way visible from the southern hemisphere. Denoted N 49, or DEM L 190, this remnant is from a massive star that died in a supernova blast whose light would have reached Earth thousands of years ago. This filamentary material will eventually be recycled into building new generations of stars in the LMC. Our own Sun and planets are constructed from similar debris of supernovae that exploded in the Milky Way billions of years ago. This seemingly gentle structure also harbors a very powerful spinning neutron star that may be the central remnant from the initial blast. It is quite common for the co

Nebula IC 2948 in Centaurus - Nebula IC 2948 and IC 2944 in Centaurus - Nebula IC 2948 is a vast nebula located about 6000 years from Earth in the southern constellation of Centaurus. It is associated with the cluster of stars IC 2944 near which Bok's blood cells are visible. 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. Image obtained through 3 different filters that highlight oxygen (blue), hydrogen (green), and sulfur (red). Between the Southern Cross and the rich Carina region, on the southern border of Centaurus, is a large, almost featureless emission nebula, IC 2948, with a sprinkling of bright stars, Collinder 249. It is against this uniform, backdrop that we see a brighter region (IC 2944) which hosts small group of dark clouds of the kind known as 'Bok globules'. They are named for the Dutch - American astronomer who first drew attention to them as the possible sites of star formation.
