Elliptical galaxy NGC 1316 in the Furnace - Giant elliptical galaxy NGC 1316 - By studying the clusters of stars and clouds of dust visible in this photo taken by the Hubble space telescope in March 2003, it is believed that the giant elliptical galaxy NGC 1316 is the result of a collision of two spiral galaxies that occurred some billions of years ago. This galaxy resides about 75 million light years ago in the cluster of galaxies of the Furnace. Also called Fornax A, it is one of the strongest radio sources in the sky. This image made from data obtained with the NASA Hubble Space Telescope reveals the dust lanes and star clusters of this giant galaxy that give evidence that it was formed from a past merger of two gas - rich galaxies. NGC 1316 is on the outskirts of a nearby cluster of galaxies in the southern constellation of Fornax, at a distance of about 75 million light - years. It is one of the brightest ellipticals in the Fornax galaxy cluster. NGC 1316, also known as Fornax A,

Nebula NGC 3372 in the Carene - The Carina nebula, NGC 3372 - The Carene nebula is located about 7000 years from the Earth. It is home to many hot stars, including the star Eta Carinae in the centre of the nebula. Image obtained by Siding Spring's 3.9m telescope. The brightest part of the Milky Way, as seen by the unaided eye, lies in the southern constellation Carina. Here there are an unusually large number of young, hot stars. Their radiation is rich in energetic ultraviolet light. Many of these stars were born within the spectacular Carinae nebula, seen here. The nebula is a cloud of glowing gas composed mostly of hydrogen. It excited by ultrviolet light from the embedded stars. This dostictive emission radiation is responsible for the red colour. About a quarter of the nebula is made of helium gas, the second most abundant element in the universe after hydrogen, and all the other chemical elements account for only a few percent of the total mass. The brightest star in the nebula i

Satellite Herschel - Illustration - Artist's view of the European satellite Herschel. The Herschel Space Observatory, scheduled to launch in 2009, will study in the infrared the formation of galaxies, stars and planetary systems. This satellite measures nearly 7 metres high by 4.3 metres wide and weighs 3.25 tonnes. Its telescope has a 3.5-meter mirror, making it the largest mirror ever made for a scientific space mission. Herschel will orbit around Lagrange 2, approximately 1.5 million kilometres from Earth. ESA's Herschel Space Observatory (formerly called Far Infrared and Submillimetre Telescope or FIRST) will solve the mystery of how stars and galaxies were born. Objects such as other planetary systems, or processes like the birth of galaxies in the early universe, can best be studied with infrared space telescopes in space. This is the reason for Esa's Herschel. ESA's Herschel Space Observatory will be bigger and better than any of its predecessors. Moreover, it will observe at wa

Constellation of the Southern Cross - The Southern Cross - The Southern Cross and the Alpha and Beta stars of Centaurus. Crux, the Southern Cross, is the smallest constellation in the sky yet one of the most distinctive, at least to those of us who live in the southern hemisphere. It was once part of Centaurus, where the bright stars Acrux and Mimosa could easly be imagined as the rear hooves of the rearing mythical centaur. However, when Christian sailors began to explore southwards in the 16th century, this memorable asterism took on a new significance. The cross appears on the national flags of several southern hemisphere countries, including Australia, though it can be seen on the southern horizon from the tropic of Cancer, 23.5 degrees north of the equator. Along with the Southern Cross is a very distinctive dark shape known as the Coalsack, much used by southern hemisphere astronomers as an indicator of a dark sky, especially if the sixth magnitude star embedded in it is visible.

Star V838 Monocerotis. 11/2005 - Star V838 Monocerotis seen by the Hubble space telescope. 11/2005 - This variable star is located about 20,000 years ago - light from Earth in the constellation Unicorn. Beginning in 2002, this star illuminated temporarily becoming one of the brightest stars in the sky. Viewed here in November 2005 by the Hubble space telescope, the light echo reveals details in the interstellar dust surrounding the star. Light from a star that erupted almost five years ago continues propagating outward through a cloud of dust surrounding the star. The light reflects or “” echoes”” off the dust and then travels to Earth. Because of the extra distance the scattered light travels, it reaches the Earth long after the light from the stellar outburst itself. Therefore, a light echo is an analog of a sound echo produced, for example, when sound from an Alpine yodeler echoes off of the surrounding mountainsides. The echo comes from the unusual variable star V838 Monocerotis (V

Centaur Omega globular cluster - NGC 5139, Omega Centauri globular cluster - Visible to the naked eye in the southern hemisphere, Centaurus Omega is the most massive globular cluster in the galaxy. About 17,000 light years ago, millions of stars nearly 12 billion years old are concentrated here. This image obtained by the ACS camera of the Hubble space telescope and observations made by the southern Gemini telescope seem to indicate the presence of a black hole in the center of the cluster. NGC 5139 is the largest and most spectacular globular cluster in the entire night sky, and the largest in our galaxy. At 36 arc minutes, Omega Centauri is larger than the full moon in apparent size. It is located about 17,000 light years away from our Sun and at 4th magnitude, is easily visible without a telescope as a “” star”” in the constellation of Centaurus. It contains about 2 million stars, almost twice as many as M13. This composite image obtained with the Advanced Camera for Surveys onboard

Spiral galaxy NGC 7424 in the Crane - Galaxy NGC 7424 in Grus - The barree spiral galaxy NGC 7424 is located about 40 million years away from Earth. NGC 7424 extends over nearly 100,000 light years, like our galaxy. Numerous bright blue clusters of massive young stars are visible along the spiral arms. Image obtained by the telescope MELIPAL of the VLT on October 9, 2004 Composite colour - coded image of spiral galaxy, NGC 7424, at a distance of 40 million light - years. This galaxy is classified as “” SAB (rs) cd””, meaning that it is intermediate between normal spirals (SA) and strongly barred galaxies (SB) and that it has rather open arms with a small central region. It also shows many ionised regions as well as clusters of young and massive stars. Ten young massive star clusters can be identified whose size span the range from 1 to 200 light - years. The galaxy itself is roughly 100,000 light - years across, that is, quite similar in size to our own Milky Way galaxy. Images obtaine

Astronomers have observed that, unlike other known spiral galaxies, it is the outer arms of this galaxy that rotate the whole, rotating in the same direction as the center; moreover, an inner arm of the galaxy would rotate in the opposite direction. A small galaxy absorbed by NGC 4622 could be responsible for this anomaly. NGC 4622 resides 111 million light - years away in the constellation Centaurus. The image taken in May 2001 with Hubble's Wide Field Planetary Camera 2 shows NGC 4622 and its outer pair of winding arms full of new stars (shown in blue).

This image is based on data from the first 15 months of Planck operation. It is the first image of this mission that shows on the whole sky the oldest emission of light that bathed our young Universe when it was only 380,000 years old. The Universe was then filled with a burning magma of protons, electrons, and photons intertwining at about 2700oC. The interaction between protons and electrons that gave rise to the hydrogen atoms then released light. As a result of the expansion of the Universe, this light has been extended until today reaches hyperfrequency wavelengths equivalent to a temperature of just 2.7 degrees above the absolute zero.

Chandra and XMM - Newton observations of the red dwarf star Proxima Centauri have shown that its surface is in a state of turmoil. Flares, or explosive outbursts, occur almost continually. This behavior can be traced to Proxima Centauri's low mass, about a tenth that of the Sun. In the cores of low mass stars, nuclear fusion reactions that convert hydrogen to helium proceed very slowly, and create a turbulent, convective motion throughout their interiors. This motion stores up magnetic energy which is often released explosively in the star's upper atmosphere where it produces flares in X - rays and other forms of light. The same

Lacaille's constellation drawing shows a remarkably detailed dial, weights and a pendulum that has little apparent connection with the scattering of faint stars in this part of the sky. There are no named stars and little else in

Detail of the nebula NGC 3324 in the Carene - Detail of nebula NGC 3324 in Carina - Detail of the nebula NGC 3324 obtained by the Hubble space telescope. This nebula is located in the southern hemisphere, close to the great Carene nebula about 7200 light years from Earth. The image obtained by the Hubble Space Telescope shows a gas wall at the edge of a cavite created by the radiation and stellar winds blown by young warm stars. Hubble space telescope image shows the edge of a giant gaseous cavity within the star - forming region called NGC 3324. The glowing nebula has been carved out by intense ultraviolet radiation and stellar winds from several hot, young stars. A cluster of extremely massive stars, located well outside this image in the center of the nebula, is responsible for the ionization of the nebula and excavation of the cavity. The image also reveals dramatic dark towers of cool gas and dust that rise above the glowing wall of gas. The dense gas at the top resists the bliste

Eagle Nebula (IC 4703) in the Snake - detail - Young stars in the Eagle nebula - Detail on young stars located in the north - west part of the Eagle Nebula (M16). Image obtained by the Hubble Space Telescope. This picture shows the northwestern part of the Eagle nebula (M16), well away from the centre, and features some very bright young stars that formed from the same cloud of material. These energetic toddlers are part of an open cluster and emit ultraviolet radiation that causes the surrounding nebula to glow. The star cluster is very bright and was discovered in the mid - eighteenth century. The nebula, however, is much more elusive and it took almost a further two decades for it to be first noted by Charles Messier in 1764. Although it is commonly known as the Eagle Nebula, its official designation is Messier 16 and the cluster is also named NGC 6611. One spectacular area of the nebula (outside the field of view) has been nicknamed The Pillars of Creation”” ever since the Hubble S
