Barree spiral galaxy NGC 1365 in the Furnace - NGC 1365, barred spiral galaxy in Fornax - NGC 1365 is a barree spiral galaxy that extends over 200,000 years - light. Located 60 million years ago - light, it belongs to the cluster of galaxies of the Furnace. Image obtained with a telescope of 30 cm, cumulative poses of 14 hours. NGC 1365 is a giant barred spiral galaxy who spans 200 000 light years across. It is located 60 million years away in the Fornax constellation. Image made from Australia with a 14.5 inches telescope; total Exposure 14 Hours

M87 elliptical galaxy in Virgo - M87 elliptical galaxy in Virgo - The M87 galaxy (NGC 4486) is located about 52 million years away - light from Earth, in the heart of the Virgin's cluster. M87 is the brightest radio source of the constellation, it is also called Virgo A. NGC 4486 (M87) is the largest and brightest elliptical galaxy within the northern Virgo Cluster at about 52 million light years from Earth. The galaxy also called Virgo A contains a notable active galactic nucleus that is a strong source of multiwavelength radiation, particularly radio waves. In 1918 astronomer Heber Curtis discovered a jet of matter coming from M87 which extends at least 5000 light - years from the nucleus of M87 and is made up of matter ejected from the galaxy, most likely by a supermassive black hole

M87 elliptical galaxy in Virgo - M87 elliptical galaxy in Virgo - The M87 galaxy (NGC 4486) is located about 60 million years ago - light from Earth, in the heart of the Virgin's cluster. M87 is the brightest radio source in the constellation, it is also called Virgo A. Image made with Siding Spring's 3.9m telescope. Messier 87 (NGC 4486) is at the heart of the Virgo cluster and has a mass many times that of the Milky Way, itself no lightweight. Unlike our galaxy however, M87 is an elliptical galaxy. Though it appears more - or - less spherical on this photograph, a deep image shows it to be markedly elongated. Also unlike the Milky Way, M87 contains relatively little gas and dust. It is composed mainly of cool stars, which gives it a yellowish colour, in contrast to the blue of spiral galaxies. Despite the lack of star - forming materials, M87 is not a quiescent backwater. It is a powerful source of radio waves and the orbits of stars near its nucleus suggest they are held by a very m

M87 is the brightest radio source in the constellation, it is also called Virgo A. Image made with Siding Spring's 3.9m telescope. Messier 87 (NGC 4486) lies near the centre of the nearby cluster of galaxies in Virgo at a distance of about 60 million light years. Although the physical boundaries of elliptical galaxies are not well defined, their mass can be, and by any standards M87 is enormous. It contains several thousand billion stars. Associated with this giant galaxy are large numbers of globular clusters, visible in this photograph as the cloud of slightly fuzzy objects around it.

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. It is an active galaxy whose energy comes from a supermassive black hole. The green dot visible in the dust strip is a supernova, the supernova 1986g. It appears green because the red filter image that made this trichromy image was only taken a year after the event and the supernova had weakened. Image obtained from the 3.9m telescope of Siding Spring, Australia. The nearby radio source Centaurus A (NGC 5128) looks like an elliptical galaxy, crossed by a broad, irregular dust lane. The dark band is probably the remains of a dusty spiral galaxy which is being absorbed by the giant elliptical. One

The distance is about 10 - 13 million light - years (3 - 4 Mpc) and the apparent visual magnitude is about 8, or 5 times too faint to be seen with the unaided eye. There is strong evidence th

It is the most important member of a group of galaxies called Hickson 96 (HCG 96). This spiral galaxy seen from the front is in interaction with other companion galaxies. It has an active core. Image obtained by the Hubble Space Telescope on June 9, 2002. NGC 7674 (seen just above the center), also known as Markarian 533, is the brightest and largest member of the so - called Hickson 96 compact group of galaxies, consisting of four galaxies. This stunning Hubble image shows a spiral galaxy nearly face - on. The central bar - shaped structure is made up of stars. The shape of NGC 7674, including the long narrow streamers seen to the left of and below the galaxy can be accounted for by tidal interactions with its companions.

NGC 1097 is a fine, barred spiral galaxy seen from a distance of about 50 million light years. The galaxy is unusual in several respects. It is a fairly strong radio source and is also bright at far infrared wavelenghts, indicating the presence of warm dust. The galaxy is also interacting woth a small elliptical galaxy, seen in the upper right (NW) corner of the picture. This galaxy shows the subtle interleaved 'shells' or stepped changes in brightness resulting from the interaction. Finally, the galaxy is k
