Star and a black hole revolving in rapid waltz

Space Telescope European Space Agency's XMM-Newton helped discover a star and a black hole that address near each other at high speed, making one revolution in just 2.4 hours - which is an hour shorter than the orbital period of the previous record holder.

A black hole in the close pair, known as the MAXI J1659-152, at least three times as massive as the Sun, while the mass of its companion star - a red dwarf star - only 20% of the solar mass. 

Record breaking flies from black hole

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.

Scientists have found a way to cool down the black hole

Samuel Grall and Alexander Le Tick the University of Maryland simulated a scenario in which the orbit of the black hole is placed satellite circling it with the same speed with which rotates itself a hole - so that the two objects remain fixed relative to each other.

Thus, they reproduce the conditions under which for those in the motion of the black holes can test the hypothesis made earlier by Stephen Hawking to the contingent of static black holes.

Milky Way's black hole goes bang powerful flash

For unknown reason, the black hole (BH), located in the center of our Milky Way galaxy, regarding once a day generates an X-ray flash. Such outbreaks last for several hours, and their brightness can in some cases exceed the normal brightness of the black hole, even a hundred times. But in February 2012, astronomers using the X-ray Observatory "Chandra", recorded the most powerful flare ever observed on the central black hole in our galaxy known as Sagittarius A *.

The smallest supermassive black hole

Who of us do not ever remember the Old New Year with a sad joy, and now we have a new oxymoron - a mini-supermassive black hole (BH). However, regardless of the fact that this black hole is the tiny class of super-massive black hole, its mass is still huge - it is about 200,000 mass of our Sun.

A team of astronomers led by Nathan Sekrestom of George Mason University, explore the galaxy NGC 4178, did not expect that at the center of this galaxy is the black hole, as NGC 4178 has pronounced bulge - bright area near the center of the galaxy, 

A rare explosion of a star discovered a black hole in our galaxy

Astronomers observe a rare type of X-ray stellar explosion near the center of our Milky Way galaxy, discovered a previously unknown black hole (BH), the engrossing gas flowing to it from the nearby sun-like star.

The find was made ​​in the last month, NASA satellite Swift, who noticed a bright X-ray source is a few degrees away from the galactic center of the Milky Way. 

Scientists have shown photon mass

The team of scientists, which included representatives of Italy, Portugal, America and Japan, has been able to find a way that would be used for astrophysical observations that would be based on the fundamental principles of their check physics problems. In particular it affected determine the mass of photons.

The test, which was used for the scientists, is the following. If the photons would have mass, then it would cause instability, which would become the reason for stopping the rotation of black holes in the universe. 

Verification a new supernova black hole

In space telescope NASA "Swift" fixed-ray flashes, indicating the discovery and the survival of a new black hole, which was previously unknown. It is located at 20-30 thousand light-years from Earth. Flash X-ray peak of the supernova occurred on September 18. Flash output is 10 thousand volts, but two days of observation exposed that the radiation has increased by 30 times.

New X-ray discovered a new black hole

In mid-September, a space telescope, "Swift" has found a rare celestial phenomenon - a new X-ray, the appearance of which specify the presence of previously unknown black hole (BH) of stellar mass.

The facility is named Swift J1745-26 in accordance with its coordinates in the sky, and the new is a few degrees away from the center of our galaxy in the direction of the constellation Sagittarius. While astronomers to calculate the exact distance to the object, but they suggest that it is from us at a distance of 20,000 to 30,000 light-years away in the inner region of our Milky Way galaxy.

Find the nearest star to the central black hole in the galaxy

An international team of researchers, with Spanish contribution, has found the closest star to Sagittarius A *, the black hole four million times the mass of the Sun located in the center of the Milky Way. It is the star S0-102; it takes 11.5 years to complete one orbit around the black hole. The work will know how to operate the law of gravity in extreme environments, according to the journal Science.

Impact of the black hole will destroy Earth in 2014

According to astrophysicists, the Earth is forthcoming cloud of unknown origin, which deletes everything in its path. It came from a black hole - at a distance of 28 000 light years from earth. Astronomers are watching for a celestial body, they say that they have found a strange bunch, which has been dubbed "sowing chaos cloud" - it destroys everything in its path: comets, asteroids, planets and stars. Now he goes to Earth.

The planets can form in the Galactic Center

Due to the insensitive environmental conditions, the planets could not form near the galactic center. However, new research conducted by astronomers at the Harvard-Smithsonian Center for Astrophysics shows that it is possible to form planets in these vortices cosmic.

                               

As evidence point to the recent discovery of a cloud of hydrogen and helium galactic heading downtown. They argue that this cloud represents the remains of a shattered protoplanetary disk orbiting a star invisible.

‘Cry' of a ragged Star messenger New Era for Testing Relativity

Last year, astronomers discovered an inactive black hole in a distant galaxy that explodes after grate and consuming a passing star. Identified Researchers now have a distinctive X-ray signal in the days Observed Following The explosion that comes from matter on the edge of falling into the black hole.

This tell-tale signal, called a quasi-periodic oscillation or QPO,

NASA's WISE Survey discover Millions of Black Holes

NASA's Wide-field Infrared Survey Explorer (WISE) mission has escort to a newfound bonanza of supermassive black holes and galaxies called extreme hot dogs, or dust-obscured galaxies. From the telescope have millions of dusty Revealed black hole candidates crosswise the universe and even dustier About 1.000 objects thought to be among the brightest galaxies ever found. These powerful galaxies, which burn brightly with infrared light, are nicknamed Hot Dogs.

Every galaxy has a black hole

Every galaxy has black holes at their center. While the black hole is active, traps and swallows all matter around it, like a whirlpool. When he is not able to swallow again, the matter continues to revolve around him, but not within. The galaxies whose black hole is still active called active galaxies.

Active galaxies are famous by their shape and the large whole of radiation they emanate. The black hole core is surrounded by a bright disc of matter, dust and hot gas. It is called the accretion disk, and spirals while emitting high energy radiation. Since the poles, the black hole space launches huge jets of particles, which can measure thousands of light years in length. The Milky Way galaxy was also active in the past.

Definitions of Nova, Black hole,Radio Galaxy, Redshirt, etc.

Nova - A star increases its brightness repentivamente and unprecedented ways, giving the impression that a new star has appeared where before there was nothing. Hence the name "nova" or again.

Recreation of a black hole

The Black hole are regions of space that concentrate a large amount of mass in its interior and a high density, which generates a gravitational field capable of attracting any particulate material. Even the photons (which are the particles that make up light) escape black holes. 

So far, astronomers have managed to look even further away in space and time (in astronomy, the greater the distance studied, the data correspond to an older universe) to analyze these regions through the telescopes powerful. However, the detection of giant black holes, hidden in the centers of galaxies, they had resisted. 

Now a team of specialists from the University of Michigan, United States, has managed to find the first direct evidence that these black holes were common in the "early universe" initial stage of the universe that followed the Big Bang.

Electromagnetic black hole

In the case of artificial black hole, not the severity needed to achieve the effect absorbent. And all thanks to artificial materials that are unusual electromagnetic properties resulting from its own structure and not its composition. King Chang and Tie Jun Cui, the State Key Laboratory of Millimeter Waves, from Nanjing University in China, designed and manufactured the artificial black hole, officially named unidirectional electromagnetic absorbed met materials using 60 strips,

black hole

One space observatory captures the perseverance of a star into a black hole. A team of researchers has found a black hole at the moment which a possible thanks to the Swift space observatory for NASA. 

"Until now, this is a unique event. Although it has long been expected that such phenomena should occur, the glow it emits is a surprise.  A researcher at Pennsylvania State University and coauthor of the published the latest issue of the journal Nature.One space observatory captures the perseverance of a star into a black hole.

Scientists have determined that the black hole is at the center of a galaxy at a distance such that the light of this phenomenon took about 4 billion years to reach us. 

Black holes are common in the center of galaxies. The Milky Way is home to one of about 2 million times the mass of our Sun Its powerful gravitational fields create strong gradients that can destroy the stars who spend many millions of miles of it and produce a flash of ultraviolet light and X rays . 

"It's what we think happened to the star absorbed in this case. The result of this process may have noticed on several occasions, but so far never been seen beginning.

The black hole of the Milky Way

Japanese astronomers has discovered that the black hole in the center of our galaxy unleashed a powerful blast for three centuries, thanks to observations with the ESA observatory XMM-Newton and other X-ray satellites and NASA Japanese.  This discovery helps solve a longstanding mystery: why the black hole of the Milky Way is so inactive.  This black hole, known as Sagittarius A-star (A *), is truly massive, contains about four million times the mass of our Sun, the energy radiated from its surroundings is billions of times weaker than the emitted from central black holes in other galaxies.
