Spiral galaxy M81 in the Great Bear - 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. In the background at the top, an irregular dwarf galaxy, Holmberg IX. This image obtained by a 50 cm amateur telescope, in February 2010 for 23 hours of poses, shows gas filaments whose origin is uncertain. Located about 12 million light - years from our planet, M81 (NGC 3031) together with M82 (NGC 3034), NGC 3077 and NGC 2976 forms one of the most iconic groups of interacting galaxies. The M81 group has also been the subject of many studies searching for and analyzing evidence of strong interactions among its components. In 1965, Halton Arp detected an unusual looping feature near M81 while examining photographic plates produced with the 48 - inch Schmidt on Mount Palomar. Traditionally, ARP's loop has been interpreted as a tail resulting from

Centaurus A elliptical galaxy (NGC 5128) in Centaurus - Elliptical galaxy Centaurus A (NGC 5128) - The galaxy NGC 5128 is located about 13 million years away from Earth in the southern constellation of Centaurus. A broad dark band crosses it in the middle, a probable vestige of a collision with a spiral galaxy. This giant galaxy is a powerful radio source known as Centaurus A. NGC 5128 is the nearest large elliptical galaxies to our sun located at about 13 million light years. It is also the nearest of the giant radio galaxies, possessing an active galactic nucleus (AGN) and optically one of the most luminous galaxies in the sky

La planete Neuf - Illustration - Planet Nine - Artwork: Vue d'artiste de la planete Neuf. The Ninth Planet is a hypothetical planet of the Solar System indirectly recorded, the existence of which is suggested by observing the orbits of several transneptunian objects. This planet would be gaseous, similar to Uranus or Neptune. A hypothetical planet in the outer reaches of the solar system orbits more than 700 times farther from the sun than earth does. A Super-earth, with an estimated mass of 10 Earths (approximately 5,000 times the mass of Pluto), a diameter two to four times that of Earth, and a highly elliptical orbit with an orbital period of approximately 15,000 years, the planet is shown as a ringed ice giant whose night side is illuminated by lightning and aurorae powered by galactic cosmic rays.

One of the richest in the Milky Way, Omega Cen contains several million stars, but unlike its southern rival, 47 Tucanae, it has a relatively open structure. Like most galactic globular clusters, the stellar population of Omega Cen identifies it as one of the oldest objects associated with the Milky Way, indeed its age is comparable to that of the Universe itself. The cluster contains a large number of RR Lyrae variable stars which enable its distance to be determined as 17,000 light years

Image made with Siding Spring's 3.9m telescope. This galaxy is of interest because of its similarity to the Large Magellanic Cloud, (LMC) our nearest extra - galactic neighbour. Like the LMC, its light comes predominantly from young stars, which are hotter than the Sun and give the galaxy a bluish colour. However, because this galaxy is over 80 million light - years distant we see only the integrated light of millions of unresolved stars, rather than the individuals we see in the LMC. NGC 4027 has a somewhat distorted appearance and an elongated spiral arm, probably due to the gravitational effect of a smaller companion galaxy, not visible in this photograph but rather obvious on a much deeper image.

Swan Constellation - Cygnus constellation - On the right, the bright star is Vega, in the constellation Lyra. Also visible are the constellations of the Fleche and the Petite Fox. Cygnus (the Swan), is clearly the bird flying along the northern Milky Way. Many legends refer to this distinctive constellation, including that of Zeus who disguised himself as a swan while visiting Leda, wife of the King of Sparta.

La Palma Observatory: Telescope FACT - La Palma Observatory: The FACT telescope: FACT (First G-APD Cherenkov Telescope) is a telescope located at the Roque de los Muchachos Observatory in La Palma, Canary Islands. One of the MAGIC telescopes is visible in the background. The First G-APD Cherenkov Telescope (FACT) is the first imaging atmospheric Cherenkov telescope using Geiger-mode avalanche photodiods (G-APDs) as photo sensors. The rather small, low-cost telescope will not only serve as a test bench for this technology in Cherenkov astronomy, but also monitor bright active galactic nuclei (AGN) in the TeV energy range. Image taken at Observatorio del Roque de Los Muchachos, Canary Islands, Spain. One of the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov Telescopes) is visible in the background. The Canary Islands are volcanic in origin and the whole observatory lies on the edge of the Taburiente volcano

Centaur Omega globular cluster - The globular cluster Omega Centauri NGC 5139 - Located 17,000 years ago - light from Earth in the southern constellation of Centaur, Omega Centauri contains several million stars and is one of the oldest objects in our galaxy. To the unaided eye this glorious globular cluster has the appearance of a hazy star and was frequently confused with Halley's comet when it drifted through Centaurus in 1986. One of the richest in the Milky Way, Omega Cen contains several million stars, but unlike its southern rival, 47 Tucanae, it has a relatively open structure. Like most galactic globular clusters, the stellar population of Omega Cen identifies it as one of the oldest objects associated with the Milky Way, indeed its age is comparable to that of the Universe itself. The cluster contains a large number of RR Lyrae variable stars which enable its distance to be determined as 17,000 light years

Most of the area of the southern Milky Way covered by this picture never sets for those of us who live at southern latitudes south on -30 degrees. The main constellations here are Centaurus, Crux and Carina, containing some of the most interesting, beautiful and bizzare astronomical objects, including the nearest stars. Alpha Centauri is at lower left and with its companion, beta points (more or less) to the Southern Cross, which in turn lies alongside the Coalsack, one of the nearest dust clouds. Further along the Milky Way is the astonishing Carina nebula, which is home to eta Carinae, probably the most massive star known, and a prime candidate for the next Galactic supernova. It is in Carina that the Sagittarius arm of our galaxy curves sharply away from us, so we see deep into a rich star-forming region.: The Lactee Way from Centaur to Carene - Souther Milky Way form Centaurus to Carina

Tarantula Nebula (NGC 2070) in the river bream - The Tarantula Nebula, around the 30 Dor cluster - The Tarantula Nebula (or 30 Bream) is the largest star-forming region of the Great Magellan Cloud. It is located 170,000 light years ago in the constellation Dorado (southern hemisphere). At the center of this nebula, the open cluster of R136 stars, clusters of hot and massive stars. Image obtained with Siding Spring's 3.9m telescope. This object is the only extra - galactic nebula which can be seen with the unaided eye. It is a faint patch of light at the eastern end of the Large Magellanic Cloud, 170,000 light years distant. A small telescope reveals narrow spindly tendrils of glowing gas which have been likened to the legs of a spider.

It is a polar ring galaxy, a fairly rare type of galaxy that features a ring of gas and dust almost perpendicular to the main galactic plane. Image made with a telescope 61 cm in diameter. NGC 660 is described as being a “” polar ring””” galaxy. Another remarkable picture of this rare type of galaxy was taken by the Hubble Space Telescope - the example in this case is NGC4650A. These galaxies are believed to have formed from the collision of two galaxies in the past. In the case of NGC 660 it would appear that our perspective is inclined from the axis of the disk so that the foreground portion of the ring does not cross the plane in the middle - but instead towards one side.

Image obtained by the 3.5m WIYN telescope at Kitt Peak and completed by data obtained by the Hubble space telescope. This image is a color - coded picture of the archetypal starburst galaxy M82. It shows the horizontal stellar disk of the galaxy, which harbors its active star formation, and a perpendicular supergalactic wind of ionized gas powered by the energy released in the starburst. To make this image, data from the WIYN 3.5 - meter telescope on Kitt Peak were combined with data from the WFPC2 camera on the Hubble Space Telescope. Purple represents e

Galaxy NGC 4027 in the Raven - Galaxy NGC 4027 in Corvus - NGC 4027 is a spiral galaxy located about 80 million years ago - light. One of his arms is more extended, probably by the presence of a nearby dwarf galaxy. Image made with Siding Spring's 3.9m telescope. This galaxy is of interest because of its similarity to the Large Magellanic Cloud, (LMC) our nearest extra - galactic neighbour. Like the LMC, its light comes predominantly from young stars, which are hotter than the Sun and give the galaxy a bluish colour. However, because this galaxy is over 80 million light - years distant we see only the integrated light of millions of unresolved stars, rather than the individuals we see in the LMC. NGC 4027 has a somewhat distorted appearance and an elongated spiral arm, probably due to the gravitational effect of a smaller companion galaxy, not visible in this photograph but rather obvious on a much deeper image. NGC 4027 is less than half a degree south of the Antennae interacting gala

Nebula NGC 6334 in the Scorpion - The 'reddened' nebulosity of NGC 6334 - The nebula NGC 6334 is located about 5500 years - light from Earth. Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. The star - forming nebula NGC 6334 shows no evidence of a blue component in their colour - indeed, the blue - light plate used in these 3 - colour pictures had no nebulous image at all - nor is there any obvious sign of the bright blue stars normally found in these objects. They are excellent examples of the phenomenon known as 'interstellar reddening', the selective removal of blue light by minute particles of dust in the line of sight. This accounts for both the ruddy hue and apparent absence of blue stars. The hot stars are present but only some of the red part of their light is seen so they are not conspicuous. This nebula is quite nearby (5500 light years) but located close to the Galactic plane and are buried in the dust of the Milky Way. Careful measurement of the colour

It's an active nucleus galaxy. Its tormented form is probably due to the attraction exerted by another galaxy, NGC 3729 (off-field). On the right, Arp 322 (or Hickson 56), is a group of 5 galaxies far farther away, located about 300 million years from Earth. NGC 3718 (Arp 214) seems to have a rudimentary bar and spiral structure although it is recognized as a peculiar galaxy and as such is listed within ARP's Atlas of Peculiar Galaxies. NGC 3718 contains an active galactic nucleus (AGN) and is known as a Seyfert type 1.9 galaxy. Its strange shape is probably due to a gravitational interaction with its companion NGC 3729 (out of field).

Open cluster M93 (NGC 2447) in Puppis - Open cluster M93 (NGC 2447) in Puppis - M93 (NGC 2447) is a cluster of age stars located 3000 years - light. Image obtained by the 3.9m telescope of Siding Spring In March, 1871 Charles Messier noted as number 93 in his famous catalogue this conspicuous group as a cluster of small stars. It was one of the last objects that Messier himself listed though he lived until 1817. The cluster is in the southern constellation of Puppis (known to Messier as Argo Puppis) and is in a rich part of the Milky Way, almost on the Galactic equator. The group is quite compact and is on the threshold of naked - eye visibility under good conditions. It is at a distance of over 3000 light years. About 80 stars have been identified as being members of the cluster, however, as in most open clusters, a mere handful contribute most of the light, reflecting the broad distribution of stellar luminosities (and thus stellar masses) found in objects of this kind.

Nebulae IC 2948 and 2944 in Centaur - A large southern emission nebula, IC 2948 - Nebula IC 2948 is a vast nebula located about 6000 years from Earth in the southern constellation of Centaur. 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. 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.

Galaxy M82 in the Great Bear seen in X-rays - The galaxy M82 seen in X-ray - Image obtained by Chandra in X-rays, reveals a cloud (in red) of very hot gas of several million degres emitted from the central regions of the galaxy. M82 is an irregular galaxy distant about 12 million years - light from Earth. Its nucleus, which appears to have suffered from the passage of the neighbouring galaxy M81, is in a phase of violent star activity. Its central regions are rich in star formation. These hot stars blow a stellar wind that becomes a very violent galactic wind. Chandra's X - ray image reveals gas that has been heated to millions of degrees by the violent outflow of matter blasting out of the galaxy. The eruption can be traced back to the central regions of the galaxy where stars are forming at a furious rate, some 10 times faster than in the Milky Way Galaxy. Many of these newly formed stars are very massive and race through their evolution to explode as supernovas. Vigorous mass loss f
