Astronomy in 2012 found that the remodeling of the universe as we know it, and to promote some of the tools, the limit of its observation capabilities.
Scientists have discovered a galaxy, hidden in a huge central black hole mass than the sun 17 billions of times. Another research team found a hot hot rocky planet in the distance to the nearest star system to our own. At the same time, record the most massive clusters of galaxies and the most distant galaxies are shattered.
This year, some of the most extreme, the most exciting of the universe there is a brief rundown.
The most weird black hole
The observer probably do not want too close to take up a large part of NGC 1277 supermassive black hole at the galaxy itself. The central black hole mass than the sun 17 billions of times, an increase of 14%, compared with the usual 0.1%, the quality of its host galaxy.
The researchers do not know what to do to the size of the black hole, they take a special year, to double-check their calculations before publish their results.
The nearest extrasolar planets Earth
In a surprising discovery, astronomers have found a planet, about the same size for Earthin star system next door. The planet was discovered only 4.3 light-years away from us, Alpha Centauri, a three-star system. Centauri star Alpha interpretation of the planets and stars (chart)]
In this world, life is unlikely. The rock surface may melt in Earth orbit from its sun-like star only 36,000 miles (600 million kilometers). (Earth, by contrast, round of 93 million miles or 150 million kilometers from the sun).
The Alpha Centauri BB, is known as the earth, is found by tracking the Earth around the gravitational wobble of its star. In this case, it is very subtle, the star of the swing is not more than 1.1 miles (1.8 km) to move back and forth. The research team pointed out that the "play to bring our technology to the limit," Some astronomers suspect the existence of the planet.
Just this month, the research team examined five potential planets, stars head Cetus It is located only 11.9 light years from Earth. The scientists said the newly discovered candidate world may be able to sustain life as we know it.
Smallest alien world
Astronomers using NASA's Kepler space telescope has found three small planet 120 light-years from Earth. The circling star KOI-961, the smallest of the three planets the size of Mars is smaller than Earth. Even the star itself is small - just larger than Jupiter 70%.
"John Johnson said:" This is the most compact planetary system, the California Institute of Technology in Pasadena. "It's like you have a shrink raygun, set for 7 times and zapped a planetary system."
The smallest of the solar system
KOI-500 five planets huddled together, of the gravity jostles each deep in their own orbit. "Year" is the only one, 3,4.6,7.1 and 9.5 days. In addition, the planet is tiny: only 1.3 to 2.6 times the size of the Earth.
The action takes place in an area 150 times smaller than the Earth's orbit, the astronomers said.
"Darling Ragozzine, a planetary scientist at the University of Florida in Gainesville, said in a statement:" At this rate, you can easily be installed in the 10 planets, they still all fit within the Earth's orbit comfortable.
The most distant galaxies
Like the 100-meter sprint world record, the record of the farthest known galaxies often change. The potential record holderis UDFj 39,546,284 has been formed in the universe is only 38 billion years old. Using new observations from NASA's Hubble Space Telescope in 2012, found its extreme age.

The oldest, most distant supernovae
In 2012, astronomers described what they think of the oldest, most distant supernovae in the universe. Some scientists believe that these "super-luminous supernovae from massive stars - 100 to 250 times the mass of the sun - that explosion and the explosion of their things into space.
Astronomers pointed out, these massive stars, gamma-ray light into electrons and antimatter positrons. Gamma rays usually prevent the gravitational collapse of the star, but the grip weakened γ-ray conversion is important. It is at this point, the star burst, triggering an explosion.
The most massive clusters of galaxies
2000 times more than the Milky Way massive, dwarf galaxies cluster is about 70 billion light-years away, almost any other known substance collected. Astronomers say, properly known as SPT-CLJ2344 4243and was called the Phoenix cluster - cluster - appears to contain thousands of galaxies of many different sizes.
Astronomers first discovered cluster of Phoenix in 2010, but did not realize that until they are no observations by NASA's Chandra X-ray Observatory. Clusters of light pouring out of the high-energy X-ray emission than last year's record holder found in 35% of the brightness.
Biggest map of universe
Courtesy of the large-scale map, the astronomers a step closer to understanding how the universe came. The Sloan Digital Sky Survey III released maps, charts, more than 100 million total volume of 70 billion cubic light years of the galaxy.
The map can help astronomers better understand the emergence of the mysterious dark matter and dark energy, so that most of the universe, researchers said.
Deepest universe
The Hubble Space Telescope peep further time. Famous orbiting observatory to capture the light generated $ 13.2 billion a few years ago, when the Universe was only 500 million years old.
Pictures of the Hubble Space Telescope, which is the so-called extreme deep field galaxies and starlight, accumulated over 10 years in a small sky, this is the best way we have seen objects very far . This photo is the Hubble Ultra Deep Field, the telescope successor to participate in the 2003 and 2004. [Video: Hubble Deep Field extreme
Most magnetar
20,000 light-years from Earth, a star, a real charisma. Perseus NGC 1624-2, which is about 35 times the quality of our sun, was found. A magnetic field is 20,000 times stronger than the sun - 10 times more powerful than any known star - NGC 1624-2 trapped charged particles around it pulled a blanket.
"This strength of the magnetic field is very rare, they exist only in the quality of some of the other stars are much lower," Greg Wade, the lead author of the study, astronomers at the Royal Military College of Canada, told SPACE.com interview in September . "To find such a strong field is very lucky."
