Quasars are very distant galaxies with extremely luminous core areas. Astronomers believe that massive black holes are the source of kvasarernes high energy show.
The supermassive black holes in quasars create such strong and very energy-rich effluents of material ejected and affect their surroundings. Astronomers have now found the most energetic outflows from a quasar ever.
Astronomers have discovered a giant black hole that is surprisingly heavy in relation to the galaxy hole live in. Super Heavy black holes in galaxies are typically several million times heavier than our Sun. But now, astronomers have found a black hole that is 17 billion times more massive than the Sun! The giant black hole at the heart of a galaxy called NGC the 1277th.
Currently seen the planets Mercury, Venus and Saturn in the morning sky before sunrise the third December is the three planets in a row.
Currently performing the three planets Mercury, Venus and Saturn a cosmic dance in the morning sky before sunrise. Thus stood Venus and Saturn very close together on 27th November, but clouds blocked unfortunately, the view of the planet parade.
If it is clear weather on Monday, the 3rd December, it will be possible to see Mercury, Venus and Saturn in a row with Mercury at the bottom, Venus and Saturn in the middle at the top.

Spacecraft Cassini recorded an incredible storm that engulfed the famous hexagon on the north pole of Saturn. The diameter of the storm more than 30,000 kilometers.
Unique video probe sent to Earth on November 27, according to NASA. He had previously recorded storm in the northern part of the planet, but only in the infrared, because it was dark.
As they note, the image of the swirling vortex "cause illusory sense of rotation" of Saturn.
Astronomers believe that December 21, 2012 - the day that very mistrustful people waiting for the end of the world - will be the most common. According to them, the Sun will have no outbreaks, and will not even magnetic storms.
"Even the magnetic storms on that day will not be", - said the director of the Astronomical Observatory of Irkutsk State University Sergei Yazev.
According to him, Russian scientists from Irkutsk, Moscow and Novosibirsk watched a total solar eclipse on the northern coast of Australia.
In the north-west of Edinburgh, near Queensberry in the construction of a road bridge over the River Forth were discovered the remains of a prehistoric house built more than 10,000 years ago.
"The construction of the bridge, designed to facilitate the development of Scotland in the future, it helped to understand the past, "- says the opening of Scotland's Transport Minister Keith Brown.
The death of the world famous turtle named Lonesome George, the last of which was considered Abingdonskih elephant skulls, not to have disposed of its kind, as previously thought.
The researchers found that live on the Galapagos Islands, at least 17 turtles, which are similar to George genetic traits, including individuals of the same is kind to him.

Although Earth takes 365 days to complete its orbit, the newly discovered pulsar does PSRJ1311-3430 in just 93 minutes, making it the neutron star in a binary system with the shortest orbital period calculated to date. It is also the first discovery of a millisecond pulsar conducted through its gamma-ray emission.
The peculiarities of this new order they are listed in the journal Science.
How much water do you think there are on Earth? Approximately 70% of the surface of the Earth is covered by water, and oceans contain about 96.5% of all water from the planet. But there is water in the air as water vapor, in rivers and lakes, ice caps and glaciers, as moisture in the soil and groundwater, even in your body and your dog. However, all that water is in the "small" area of 1,385 km in diameter.
On December 31, the Gregorian calendar did something frightening. He spent the years 2011 to 2012. What we experience as the year came to an end? Earthquakes? Globally? A planetary collision? Stranger gravitational effects caused by an alignment with the galactic plane? Is the impact of a comet? 'Lighting' Earth?
As much as I wish it were true finally, it is likely that the New Year celebrations only involve a lot of alcohol and fireworks. It is the beginning of a new year for our calendar. Nothing more, nothing less.

The cooling system of a nuclear reactor with heat pipes can be used during space flight.
A group of researchers from LANL, NASA and NSTec (USA) established the use of heat pipes for cooling a small nuclear reactor that drives the Sterling engine. The system can be used as a dependable energy source for space vehicles.
The study, conducted by a team of scientists led by Dmitry Kryukov, a physicist from the University of California, San Diego, show that some as yet undiscovered, fundamental laws can control the growth of both small and large systems, from the transmission of nerve impulses between brain cells and the growth of social networks and to expanding galaxies.
The new model, created by a group of scientists led by Justin Erwin, lead author of the study and a PhD from the University of Virginia, predicts that Pluto's atmosphere may reach nearly 10,390 miles into space, which is about 4.5 diameter of Pluto. This is more than half the distance from Pluto to Charon.

Is December on the doorstep? Does this mean that awaits us last month of life on this planet, and whether a doomsday in 2012? We interviewed NASA scientists and their response surprised us. Read the article - it's interesting!
During the entire existence of mankind been countless theories about how our planet will cease to exist.
The Martian satellite Phobos could be the result of contact with Phobos debris ejected from the craters of the Red Planet during its bombardment by space objects, a new study indicates.
To explain the nature of the mysterious troughs are abundantly present on the surface of Phobos, in 2011, a group of American scientist John Murray has been proposed,
This finding sheds light on the formation of new planets. Mass of the new planet is 13 times greater than the mass of Jupiter, the largest planet of the solar and heavy systems. Previously, scientists doubt that the planet can be formed from a protoplanetary disk as massive stars, like Kappa Andromeda. To date, more than 800 planets discovered outside our solar system, but scientists have been able to photograph a few of them.

According to scientists, a single supernova explosion in the surrounding area can be radioactive titanium, the total weight of which can exceed 100 times the mass of our planet.
These new data, to dispose of the radioactive substance during a supernova explosion, it may give an explanation of the mysterious processes occurring inside stars just before they are followed by a catastrophic explosion and the release of elements from which the universe is almost everything, from the stars and planets and ending human .
This advanced technology is developed in the field of measurement, at the atomic level, the degree of change in ambient gravity , as well as for the detection of gravitational waves - ripples sort of space-time, which is caused by various events, including the Big Bang. According to the general theory of relativity, Albert Einstein created; gravitational waves are provided when massive cosmic bodies, during its motion, break the fabric of space and time.
Through the use of Hubble and Keck telescopes, astronomers have come to a rather startling conclusion about the nature, which is the process of change in the "blue" galaxies. Specifically, it relates to a process of change that takes place in these galaxies has for now as eight billion years - in other words, for the period, which is more than half the age of the universe.
Until now, it was assumed that the disk-shaped galaxy with a classic for these galaxies form, appeared in the universe, in its present form, about 8 billion years ago, and only slightly changed in all that time.

Vatican priest-astronomer believes in the survival of extraterrestrial galaxy. The possibility of intelligent life beyond Earth is regularly discuss at a conference held at the initiative of the Catholic Church. Director of the Vatican Observatory, the Jesuit priest Jose Funes does not exclude the existence of life beyond Earth. "Up to now we have not found any evidence that there is extraterrestrial life" - said the astronomer.

Team Mission Mars Science Laboratory implied that they have some important news that they will be ready to share soon. But, like all serious scientists, they are awaiting confirmation of their results before say something specific. In an interview with the American radio station National Public Radio (NPR) science mission chief John Graettinger said that a sample of Martian soil, studied recently with the tool SAM (Sample Analysis at Mars) rover Curiosity, showed something "stunning ('earthshaking').
Sized planet about 1.4 times larger than Jupiter is captivated by its own star for a solid veil of gas, according to new observations made space telescope "Hubble".
The planet WASP-b is a gas giant, spinning dangerously close to its parent star so that its evaporation created a dense cloud of gas that does not pass light.
A powerful supercomputer showed that the type of unusually faded stellar explosion can be recognized, in all probability, to the failed attempt to blow up a white dwarf.
A team of scientists led by George Jordan, researchers at Flash Center for Computational Science, University of Chicago, compared the unusually dim supernova type 1a supernovae with the normal of the same type.
A team of Carnegie investigated hydrogen liquefy in water from the Martian subsurface, and found that Mars was formed from the same structure blocks as the Earth, and the changes in the chemical composition of the planet began to occur in the course of its subsequent evolution. This indicates that the terrestrial planets, including Earth, the same source of water - chondritic meteorites. However, unlike our planet, Mars rocks, which contain volatile components such as water, can be processed deep in the bowels of the planet.

If procedures are not taken to stop climate change by the end of this century, temperatures worldwide could rise by 4 degrees. World Bank does not rule out that even if all the nations of the world to meet the commitments to reduce greenhouse gas emissions is likely to happen at a temperature rise of 3 degrees.
Mars rover Curiosity during the analysis of samples of Martian soil found something very interesting, but scientists refuse to say what the rover found - specialists intend to double-check everything again and eliminate errors, according to the American radio station NPR.
"We receive data from the SAM (Sample Analysis at Mars - chemical laboratory aboard the rover) ... and these data seem to be very interesting.

Radiation levels on the surface of the Red Planet is equivalent to environment radiation in low Earth orbit, NASA discovered Martian rover Curiosity.
The first measurements of radiation levels - the first held on the surface of another planet - can cheer those who want to see how once on Mars for the first time set foot on the person: Curiosity rover found that people may well spend some time on the surface of the Red Planet.
When dying stars detonate as supernovae, spread out a shock wave lead the so-called "rebound" - matter and elementary particles are compressed towards the center of the star to achieve the density that come into play in the nuclear force.
In the development of a supernova nuclear particles can create different and often bizarre forms, such as rods, plates or vials and long threads - which gave the name to this phenomenon, associated with the famous Italian pasta. Creating a "paste" because in the dying star DIURNAL two types of forces - the Coulomb revulsion of the same charges and nuclear forces of attraction.
Hydrothermal cracks around Martian impact craters could be suitable places for living organisms, according to scientists.
The new study, manner jointly by the University of Leicester and the Open University, led by lead author John Bridges of the University of Leicester has determined that the temperature on Mars were in the range of about 50 to 150 degrees Celsius. On Earth, microbes can survive in such an environment, such as the volcanic thermal hot springs of Yellowstone National Park, USA, suggest the researchers.

Astronomers have discovered a budding system of planets. Artistic representation of an image PDS 70.Infrakrasnoe protoplanetary disk PDS 70, received a tool HiCIAO. The picture shows a dark empty area near the star.
At a distance of 460 light-years from Earth, the planetary system formed. Found”new-born” Japanese scientists.
Google has released an application for discover the universe:
The developers of the team Google Data Arts Team, the project created a beautiful Chrome Experiments demo 100,000 stars ", which shows the actual location of more than 100 thousand around the stars, the sun.
The development team Google Data Arts has released a new, experimental application for the browser Chrome, offers a virtual tour of our local stellar neighborhood.
Astronomers have discovered a curious disk of gas and dust surrounding a system of two stars, the origin of which scientists cannot explain the basis of the standard models of planetary evolution.
A binary star system (with a simple name of SDSS J0303 +0054) is composed of white and red dwarfs, separated by distance of about 700,000 kilometers, the distance between the two stars is a very small value.
Space telescope, "Kepler", designed to search for planets outside the solar system, has completed the major part of their mission, but will continue for another four years. The announcement was published on the website NASA.
For three and a half years of the Space Telescope, scientists were able to detect more than two thousand objects candidates for the title of exoplanets.
Star cluster, which had previously been measured part of the spectacular Orion Nebula, is actually a separate creature, located in front of the nebula, according to a new study.
Scientists are using the Canada-French-Hawaii Telescope, located in Hawaii, discovered that the star cluster NGC 1980 is a separate group of massive stars in front of the Orion Nebula, which lies at a distance of about 1,500 light-years away and is one of the closest Earth "stellar nurseries". Accumulation unevenly scattered around the star iota Orion, located in the southern part of the "sword" of the constellation Orion.
Since the planets in the solar system formed from the same cloud of gas and dust that the star itself, until recently, it was thought that the plane of their orbits must coincide with the plane of rotation of the star. However, beginning in 2008, astronomers began to find more and more exoplanets, which were in highly inclined orbits and even reverse (counter-rotating) with respect to its star.

Pinch of fine sand and dust was the first solid Martian samples placed in the biggest tool of NASA's Mars rover Curiosity: Sample Analysis at Mars, or SAM.
Inside the rover, SAM determine the chemical composition of samples placed inside it, special attention is paid to the search for fragments, which could indicate the former presence of the world traces of organic life. Curiosity robotic arm delivered to the inlet of the tool SAM, located on the deck of the rover, a sample of Martian soil on 9 November.
Very bright supernova lit galaxy NGC 1365, also known as the Great Barred Spiral Galaxy, visible to observers from the Southern Hemisphere. This elegant galaxy lies at a distance of approximately 56 million light-years away in the constellation Fornax. SNe Ia, in question, was opened by Alain Klotz with the telescope of TAROT La Silla Observatory, Chile, October 27, 2012
Supernova 2012fr a vivid, deep blue star, located directly under the center of the galaxy. The author of this picture, Rolf Olsen Bullock, said November 10, 2012, this supernova was close to its maximum brightness, reaching a magnitude in the color bar R, equal to 11.90.
On the way from the International Space Station and other space vehicles that move at a relatively short distance from the Earth, a new threat - a cloud of more than 500 pieces, formed by the explosion of the Russian upper stage.
The explosion in orbit rocket engine "Breeze-M" was the third explosion engine for our country, starting in 2007; engines were left in elliptical orbits that intersect the ISS and some satellites.

In the week 22 ranged Manfred Kiau up an Adwa on Sun. "The sun is something going on," it said. Now he has, Ulrich Teschke, Frank Gasparini and Elisabeth Kollner taken a Northern Lights excursion. In the period from 08 to 21.10.2012, the trip went to the Lofted Islands. This archipelago lies in the far north of the Norwegian Atlantic coast, beyond the 68th Latitude. The aim of the observer group was there to document the effects of solar activity in the terrestrial atmosphere: auroras as photogenic, best with reflections in the water.
The 192 light years distant star 49 Cetin is surrounded by a huge ring of comets, which occurs about every six seconds in a collision. With these circumstances, two American astronomers solve an unsolved problem for 17 years: the star is surrounded by a cloud of unusual carbon monoxide. The comet collisions release the gas, the researchers said in the journal "Astrophysical Journal."
This colorful view of the globular cluster NGC 6362 has been with the Wide Field Imager on the ESO / MPG 2.2-meter telescope was added to the ESO La Silla Observatory in Chile. Together with a new recording of the central region of the cluster, which has delivered the Hubble Space Telescope by NASA and ESA, this picture conveys the best to date view of this little-known globular cluster. The majority of stars in globular clusters is very old. In this bunch there are also some stars that act unusually young.

The Mars Pathfinder mission was designed to be a revelation of the technology to put a lender and a rover on the surface of Mars so for cost effective and resourceful. Pathfinder not only met their goal, but also sent to Earth an amount of data and outshine extraordinary uptime for which it was designed.
Mars Pathfinder used an innovative method to enter directly into the Martian atmosphere, aided by a parachute to slow its descent through the thin Martian atmosphere and a giant system of airbags to cushion the impact.
Live To observe the total solar eclipse on Tuesday 13 November, several scientific expeditions have moved to the Australian state of Queensland. One is 'Mission eclipse', which, in collaboration with the Newspaper of Catalonia, and Alumni UB (University of Barcelona), cover the relay from a privileged location in Cairns (Queensland), overlooking the Barrier Reef Pacific Ocean.
Although at first fleeting look the sun seems always the same, their activity is actually some activity cycles of about 11 years, discovered in 1843 Samuel Heinrich Schwabe, after 17 years of observations of sunspots.
It is often said that last eleven years have actually seen cycles of nine and fourteen others.
