10 most amazing galaxy

2MASX J00482185-2507365

2MASX J00482185-2507365 occulting galaxy pair is a pair of overlapping spiral that found around NGC 253, the Sculptor Galaxy. The two galaxies are more distant than NGC 253, with a background galaxy, 2MASX J00482185-2507365, lying in the redshift z = 0.06, and the foreground galaxy NGC located between 253 and galaxies in the background (0.0008 <>


Black Eye

A spiral galaxy in the constellation Coma Berenices, Messier 64, the famous “Black Eye” galaxy or “Sleeping Beauty galaxy,” has a spectacular dark band of dust in front of the absorbing galaxy bright core. It’s well known among amateur astronomers because of his appearance in a small telescope.


Sombrero

The Sombrero Galaxy (also known as M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo. Has a bright core, huge central bulge and prominent dust disk inclined road. The dark dust lane and the bulge of this galaxy gives the appearance of a sombrero. Galaxies have apparent magnitude of 9.0, so easily seen with amateur telescopes. Large bulge, the central supermassive black holes, and dirt roads all the attention of professional astronomers that occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. As the first supernova discovered in 1987, it was labeled “1987a”. Brightness which culminated in May with a clear amount of about 3 and slowly declined in subsequent months. This is the first opportunity for modern astronomers to see a supernova up close.


Galaxy NGC 3370

Dusty spiral galaxy located about 98 million light-years away toward the constellation Leo, NGC 3370 shows the central dust lane is well illustrated and extraordinary ill-defined nucleus. This view is NGC 3370 obtained by the Hubble Space Telescope using the camera to survey and sharp enough to identify individual Cepheid variable stars in the galaxy. Cepheid variable stars are used to determine extragalactic distances. In 1994, he exploded in sypernova Type NGC 3370. (Credit: NASA, The Hubble Heritage Team and A. Riess; STScI) galaxy is about 70,000 light years across, which is almost as large as our own Milky Way galaxy. Core galaxy remarkable for its “circumnuclear” Starburst ring, which is a remarkable circle of groups of young stars that includes several light years in 2400. Galaxies “starbursts” is a passionate episode of new star formation and galaxy found in various environments.


Grand Spiral Galaxy

Grand Spiral Galaxy also known as NGC 123, this amazing galaxy is dominated by millions of bright stars and dark dust, caught in a spiral arm gravity vortex swirling around the center. Open star clusters containing bright blue stars can be seen sprinkled along these spiral arms, while the dark line of solid interstellar dust can be seen sprinkled between them. Less visible, but can be detected, is widely billions of dim normal stars and interstellar gas, together with a high mass held like they dominate the dynamics of the inner galaxy. Invisible is a greater amount of material in a form that we do not yet know - pervasive dark matter needed to explain the movement seen in the outer galaxy.


Supernova 1987 A

Two decades ago, the astronomers saw one of the brightest exploding stars in more than 400 years: a doomed star, called Supernova 1987a. This figure shows the entire region around the supernova. The most prominent feature in the image is a ring with dozens of bright spots. A material shock waves caused by an exploding star that hit the area along the inner ring, heating them and causing them to glow. Ring, around the year across the light, might shed by the star about 20,000 years before it exploded. In the next few years, the entire ring will light up like an accident to absorb the full force. Ring burning is expected to be bright enough to illuminate the star surroundings, providing astronomers with new information about how the star expelled material before the explosion. The picture was taken in December 2006 with Hubble’s Advanced Camera for Surveys. (Credit: NASA, ESA, and R. Kirshner; Harvard-Smithsonian Center for Astrophysics)


Galaxy NGC 1512

A spiral galaxy located about 30 million light-years away toward the Horologium constellation, Galaxy NGC 1512 is bright enough to be seen with amateur telescopes. The galaxy is about 70,000 light years across, which is almost as large as our own Milky Way galaxy. Core galaxy remarkable for its “circumnuclear” Starburst ring, which is a remarkable circle of groups of young stars that includes several light years in 2400. Galaxies “starbursts” is a passionate episode of new star formation and galaxy found in various environments.


The Whirlpool Galaxy

The Whirlpool Galaxy, also known as Messier 51A, M51a, or NGC 5194, Whirlpool Galaxy is a grand-design spiral galaxy interaction that lies at a distance of about 23 million light-years away in the constellation Cane Venatici. This is one of the most famous spiral galaxies in the sky. And the companion galaxy (NGC 5195) is easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target of professional astronomers, who studied to better understand the structure of galaxies (particularly structure associated with spiral arms), and galaxy interactions.


Spiral galaxy M81

Big and beautiful spiral galaxy M81, in the northern constellation Ursa Major, is one of the brightest galaxies visible in the sky of planet Earth. This extraordinary detailed view reveals a bright nucleus, a large spiral arms and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hinted in the past that chaotic, dusty streets that used to walk straight out through the disk, below and right of the galactic center, contrary to other leading M81 spiral features. Errant dust lane may be firmly attached the results of a meeting between the galaxies M81 and the smaller companion, M82. Control variable stars in M81 (aka NGC 3031) has produced the best one to determine the distance of external galaxies -11.8 million light years.


Hoag’s Object

Not typical, type of galaxies known as the ring galaxy, Hoag’s Object appearance has attracted as many amateur astronomers common structure professional fascinated. Is this one galaxy or two? This question was revealed in 1950 when astronomer Art Hoag in extragalactic coincidence that this strange object. Outside is a ring dominated by blue stars bright, while located near the center of the ball a lot of red stars that may be much older. Between the two is the gap that appears almost completely dark. How Hoag’s Object formed remains unknown, although similar objects have now been identified and are collectively labeled as a form of ring galaxy. Genesis hypothesis including collisions of galaxies billions of years ago and perturbative gravitational interactions involve the core incredible shape. The above photo was taken by the Hubble Space Telescope in July 2001 had never happened before revealing the details of Hoag’s Object, and can produce a better understanding. Hoag’s Object a range of about 100,000 light years and lies about 600 million light-years away toward the constellation Serpens. Incidentally, look at the ring gap again galaxies that may lie far in the distance.
