Constellation Belier - Aries constellation - Constellation Belier and cluster of Pleiades (in the Taurus). Although inconspicuous, Aries is one of the constellations of the zodiac and from ancient times has been represented by a ram, the same ram whose golden fleece was sought by Jason and the Argonauts in the great ship Argo Navis. For more than 2000 years it also of astronomical importance because it was the constellation where the Sun crossed the celestial equator (ecliptic) each year at the vernal equinox, marking the first point in Aries from which right ascension is measured. Precession has now carried this point into Pisces. The constellation is the 39th largest in the sky and covers about 440 square degrees. The best - known object in this field is the Pleiades star cluster (M45 in Taurus)

Blue stragglers in cluster 47 Toucan - Blue stragglers in globular cluster 47 Tucanae - This image obtained by the Hubble space telescope shows a detail of the 47 Toucan cluster near its center (the field is indicated on the left image taken from the ground). The yellow circles on the right image indicate the position of stars identified by the telescope as blue trainers. Because of the high density of stars within a globular cluster, a collision between two stars sometimes occurs, merging into a single young, bright and warm star called a blue straggler. The core of globular cluster 47 Tucanae is home to many blue stragglers, rejuvenated stars that glow with the blue light of young stars. A ground - based telescope image (on the left) shows the entire crowded core of 47 Tucanae, located 15,000 light - years away in the constellation Tucana. Peering into the heart of the globular cluster's bright core, the Hubble Space Telescope's Wide Field and Planetary Camera 2 separated the dense c

Cometary blood cell CG4 in the stern - Cometary blood cell CG4 - Cometary blood cells are small clouds of isolated gases. The latter, called CG4, is located about 1300 light years ago in the constellation of Pupus. Its head is 1.5 years - light and its tail (off-field) extends for 8 years - light. This cloud is a star-forming region. Image obtained by the VLT. The cometary globule CG4 glows menacingly in this image from Eso's Very Large Telescope. Although it looks huge and bright in this image it is actually a faint nebula and not easy to observe. The exact nature of CG4 remains a mystery

Globular cluster M107 in Ophiuchus - Globular cluster M107 in Ophiuchus - The globular cluster M107 (NGC 6171) is approximately 21,000 years - light in the constellation Ophiuchus. Image obtained from the 2.2m MPG/ESO telescope in Chile. The globular cluster Messier 107, also known as NGC 6171, is located about 21 000 light - years away in the constellation of Ophiuchus. Messier 107 is about 13 arcminutes across, which corresponds to about 80 light - years at its distance. As is typical of globular clusters, a population of thousands of old stars in Messier 107 is densely concentrated into a volume that is only about twenty times the distance between our Sun and its nearest stellar neighbour, Alpha Centauri, across.

The image reveals in the center of the image a young star accompanied by a jet of material. NGC 3372 is located about 7000 light years away from Earth. Image obtained in July 2009. Composed of gas and dust, the pictured pillar resides in a tempestuous stellar nursery called the Carina Nebula, located 7500 light - years away in the southern constellation of Carina. Taken in infrared light, the image shows the dense column and the surrounding greenish - coloured gas all but disappear. Only a faint outline of the pillar remains. By penetrating the wall of gas and dust, the infrared vision of WFC3 reveals the infant star that is probably blasting the jet. Part of the jet nearest the star is more prominent in this view. These features can be seen because infrared light, unlike visible light, can pass through the dust. Hubble's Wide

Detail of the Eagle Nebula (M16) dans le serpent/HST - This eerie, dark structure, resembling an imaginary sea serpent's head, is a column of cool molecular hydrogen gas (two atoms of hydrogen in each molecule) and dust that is an incubator for new stars. The stars are embedded inside finger - like protrusions extending from the top of the nebula. Each “” fingertip”” is somewhat larger than our own solar system. The pillar is slowly eroding away by the ultraviolet light from nearby hot stars, a process called “” photoevaporation””. As it does, small globules of especially dense gas buried within the cloud is uncovered. These globules have been dubbed “” Eggs”” - - an acronym for “” Evaporating Gaseous Globules””. The shadows of the Eggs protect gas behind them, resulting in the finger - like structures at the top of the cloud. Forming inside at least some of the Eggs are embryonic stars - - stars that abruptly stop growing when the Eggs are uncovered and they are separated from the lar

Barree spiral galaxy NGC 2146 in the Giraffe - Barred spiral galaxy NGC 2146 in Camelopardalis - NGC 2146 is a barree spiral galaxy located about 70 million years ago - light from Earth in the constellation Giraffe (Camelopardalis). Image obtained by the Hubble Space Telescope (HST). NGC 2146 is classified as a barred spiral due to its shape, but the most distinctive feature is the dusty spiral arm that has looped in front of the galaxy's core as seen from our perspective. The forces required to pull this structure out of its natural shape and twist it up to 45 degrees are colossal. The most likely explanation is that a neighbouring galaxy is gravitationally perturbing it and distorting the orbits of many of NGC 2146's stars. It is probable that we are currently witnessing the end stages of a process which has been occurring for tens of millions of years. NCG 2146 is undergoing intense bouts of star formation, to such an extent that it is referred to as a starburst galaxy. This is a co

This image gives the first clear view of the faint boundary of the Crab Nebula's X - ray - emitting pulsar wind nebula. The nebula is powered by a rapidly rotating, highly magnetized neutron star, or pulsar (white dot near the center). The combination of rapid rotating and strong magnetic field generates an intense electromagnetic field that creates jets of matter and anti - matter moving away from the north and south poles of the pulsar, and an intense wind flowing out in the equatorial direction.

Cepheides in the galaxy M81 - Cepheids in the galaxy M81 - Cepheides are very bright variable stars that serve as cosmic beacons to measure distance from nearby galaxies. Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope identified cepheides in the M81 galaxy; astronomers were able to deduce a new distance for this galaxy; it would be 11 million years - light from Earth; previous estimates gave a figure of 18 million light years.

Cepheides in the galaxy M81 - Cepheids in the galaxy M81 - Cepheides are very bright variable stars that serve as cosmic beacons to measure distance from nearby galaxies. Their pulse period is measured and their absolute luminosite is calculated. By comparing the result to their apparent luminosite in the sky, they can be calculated accurately. Here, the space telescope identified cepheides in the M81 galaxy; astronomers were able to deduce a new distance for this galaxy; it would be 11 million years - light from Earth; previous estimates gave a figure of 18 million light years.

The little - known nebula IRAS 05437+2502 billows out among the bright stars and dark dust clouds that surround it in this striking image from the Hubble Space Telescope. It is located in the constellation of Taurus (the Bull), close to the central plane of our Milky Way galaxy. It appears to be a small, rather isolated, region of star formation and one might assume that the effects of fierce ultraviolet radiation from bright young stars probably were the cause of the eye - catching shapes of the gas. However, the bright boomerang - shaped feature may tell a more dramatic tale. The interaction of a high velocity young star and the cloud of gas and dust may have created this unusually sharp - edged bright arc.

Image obtained from the 1.2m Schmidt UK telescope of Siding Spring. Orbiting round the centre of our Galaxy are found huge numbers of stars which are mostly faint, cool and often billions of years old. They are as ancient as the Galaxy itself. These stars are seen with the unaided eye as the hazy star clouds of the southern Milky Way, especially rich in Sagittarius. Our line of sight in this direction is strongly affected by dust, which reveals itself by both dimming the starlight passing through it and by selectively removing the blue light, changing the apparent colour to a deeper yellow. Though the colour change is only seen in photographs such as this, the dustiness of the Milky Way is obvious to the unaided eye.

Barree spiral galaxy NGC 2442 in Flying Fish - Barred spiral galaxy NGC 2442 in Volans - NGC 2442 is a barree spiral galaxy located about 50 million years ago - light. Its asymmetrical shape suggests that a galaxy interacts with it. Image obtained by the 2.2 meter MPG/ESO telescope at the La Silla Observatory. NGC 2442 is a barred spiral galaxy about 50 million light years away in the constellation Volans. This picture of the Meathook Galaxy (NGC 2442) was taken by the Wide Field Imager on the MPG/ESO 2.2 - metre telescope at La Silla, Chile. This view includes the whole galaxy and the surrounding sky, and clearly shows the asymmetric spiral arms. The longer of the two arms has intense star formation, which is visible here as a pink glow: this is due to the radiation of young stars ionising the gas they form from. The asymmetric shape and star formation are both thought to be caused by tidal disruptions from a near - miss with another galaxy at some point in its history
