Cone Nebula NGC 2264 in the Unicorn - The Cone Nebula NGC 2264 in Monoceros - The Cone Nebula is a region H II located about 2600 years from Earth. It is accompanied by a cluster of stars called the Christmas tree. The bright star at the top is S Monocerotis, a star of magnitude 4.7. Image obtained by the 2.2m telescope of La Silla. NGC 2264 and the Christmas Tree cluster lies about 2600 light - years from Earth in the constellation of Monoceros, the Unicorn, not far from the more familiar figure of Orion, the Hunter. The image shows a region of space about 30 light - years across. The cluster is very bright and can easily be seen with binoculars. With a small telescope (whose lenses will turn the view upside down) the stars resemble the glittering lights on a Christmas tree. The dazzling star at the top is S Monocerotis, bright enough to be seen with the unaided eye. It is a massive multiple star system that only emerged from the dust and gas a few million years ago.

Interacting galaxies UGC 8058 - Interacting galaxies UGC 8058 - The galaxy UGC 8058 (Markarian 231) is located about 600 million light years away from Earth in the constellation Big Bear. This interacting galaxy houses a quasar in its center. It is one of the brightest ultra-bright infrared galaxy known to date. It has a central black hole and intense star formations are observed. Image obtained by the Hubble Space Telescope on May 10, 2002. The extraordinary galaxy UGC 8058, also known as Markarian 231, was discovered in 1969 as part of a survey searching for galaxies with strong ultraviolet radiation. It has long tidal tails and a disturbed shape. Results from the first spectrum showed clear signs of the presence of a powerful quasar in the center that made Markarian 231 unique in the Markarian sample. Markarian 231 has maintained its reputation as an exceptional object since those early observations and continues to be a favorite target in all wavelength regimes. Its infrared lumino

Kepler - 186f, the first Earth - size Planet in the Habitable Zone - Kepler - 186f is the first Earth-sized planet in the habitable zone of its star to be discovered. It orbits Kepler - 186, a red dwarf located in the constellation of Swan, between 490 and 500 years of light from the Earth. The artist's concept depicts Kepler - 186f, the first validated Earth - size planet to orbit a distant star in the habitable zone - - a range of distance from a star where liquid water might pool on the planet's surface. The discovery of Kepler - 186f confirms that Earth - size planets exist in the habitable zones of other stars and signals a significant step closer to finding a world similar to Earth. The size of Kepler - 186f is known to be less than ten percent larger than Earth, but its mass, composition and density are not known. Previous research suggests that a planet the size of Kepler - 186f is likely to be rocky. Prior to this discovery, the “” record holder”” for the most “” Earth - like”

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. Image obtained with a 35 cm telescope, 11 hours of cumulative poses. NGC 5128 is the nearest large elliptical galaxies to our sun 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. In 1949, NGC 5128 was found to be a loud source of radio energy, in fact the loudest radio source in its region of the sky (second overall to Cygnus A), earning it the designation Centarus A.

This galaxy is home to many Cepheides, variable stars used to accurately measure distances in the universe and calculate the rate of expansion of the universe. Image obtained by the Hubble Space Telescope. The brilliant, blue glow of young stars traces the graceful spiral arms of galaxy NGC 5584 in this Hubble Space Telescope image. Thin, dark dust lanes appear to be flowing from the yellowish core, where older stars reside. The reddish dots sprinkled throughout the image are largely background galaxies. Among the galaxy's myriad stars are pulsating stars called Cepheid variables and one recent Type Ia supernova, a special class of exploding stars. Astronomers use Cepheid variables and Type Ia supernovae as reliable distance markers to measure the university's expansion rate.

The object shown in this beautiful Hubble image, dubbed Messier 54, could be just another globular cluster, but this dense and faint group of stars was in fact the first globular cluster found that is outside our galaxy. Discovered by the famous astronomer Charles Messier in 1778, Messier 54 belongs to a satellite of the Milky Way called the Sagittarius Dwarf Elliptical Galaxy. Messier had no idea of the significance of his discovery at the time, and it wasn't until over two centuries later, in 1994, that astronomers found Messier 54 to be part of the miniature galaxy and not our own.

Spiral Galaxy M66 in the Lion - Spiral galaxy M66 in Leo - M66 (NGC 3627) is a spiral galaxy located at a distance of about 35 million years - light. M66, with its neighbors M65 and NGC 3628, forms a remarkable triplet of galaxies, called the Lion Triplet or the M66 Group. Image obtained by the Hubble Space Telescope. The unusual spiral galaxy, Messier 66, is located at a distance of about 35 million light - years in the constellation of Leo. Together with Messier 65 and NGC 3628, Messier 66 is one third of the Leo Triplet, a trio of interacting spiral galaxies, part of the larger Messier 66 group. Messier 66 wins out in size over its fellow triplets - - it is about 100 000 light - years across. Messier 66 is the proud owner of exclusive asymmetric spiral arms which seem to climb above the galaxy's main disc and an apparently displaced nucleus. This asymmetry is unusual; most often, dense waves of gas, dust and newly born stars wind about the galaxy's centre in a symmetric way. Astrono

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

Red Dwarf Star Proxima of Centauri - Proxima Centauri in X - Ray - Proxima of Centaur (in the center of the image) is the closest star to the Sun, at a distance of 4.2 years - light. It belongs to the triple Alpha star system of the Centaurus being the least bright star of this system; it is a red dwarf star. X-ray image obtained by the Chandra space telescope. 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

It has ejected its envelope of gases and is now unleashing a stream of ultraviolet radiation that is making the cast - off material glow. This object is an example of a planetary nebula, so - named because many of them have a round appearance resembling that of a planet when viewed through a small telescope. The Wide Field Camera 3 (WFC3), a new camera aboard Nasa's Hubble Space Telescope, snapped this image of the planetary nebula, catalogued as NGC 6302, but more popularly called the Bug Nebula or the Butterfly Nebula. WFC3 was installed by NASA astronauts in May 2009, during the

Brown dwarf around the red dwarf star Gliese 229 - Brown dwarf around red dwarf Gliese 229 - First false-colored image of a brown dwarf. With a mass of 20 to 50 times that of Jupiter, but of a diameter equivalent to the gas planet, GL229B, is orbiting around the red dwarf star Gliese 229, about 18 years - light from Earth in the constellation Lievre. On the left, the observation made from the ground in adaptive optics at Mount Palomar, October 27, 1994. On the right, the image obtained by the Hubble space telescope on November 17, 1995. These two false - color telescope images reveal the faintest object ever seen around a star beyond our Sun, and the first unambiguous detection of a brown dwarf. The brown dwarf, called GL229B, orbits the red dwarf star Gliese 229, located approximately 18 light - years away in the constellation Lepus. The brown dwarf is about 20 - 50 times the mass of Jupiter, but is so dense it is about the same diameter as Jupiter (80,000 miles). Brown dwarfs are a m
