in 1783 was first mentioned in a letter to the royal society, the black hole has attracted scientists, writers, filmmakers and the attention of other artists.They constructed many the appearance of a black hole, just because this mysterious object has never been observed.
but now want to change, the United Nations scientists team on April 5, will use all the telescope array on the earth together to form a huge of telescope is similar to the size of the earth, they described the plan as "telescope" horizon horizon to measure center of our Milky Way galaxy Numbers for: SgrA * super massive black hole.
black hole is the area of hyperspace, its gravity is extremely strong, nothing not even light can escape its gravitational pull.They are ever mentioned in Einstein's general theory of relativity.
astronomers already has a lot of evidence to suggest that the presence of a supermassive black hole, the ten thousand to one billion times larger than our sun quality is located in the center of the large galaxies.This is because they can be observed gravity of stellar orbits around the galactic center.When observed around the galactic center, they can also be detectable rays x-rays or plasma at nearly the speed of light emission.Last year's experiment provides more evidence, through millions of years ago the merging of two medium quality caused by the phenomenon of the black hole, scientists caught gravitational waves and the existence of dark matter.
although, we now know that black holes exist about the origins of the universe.But the evolution of the universe and the origin and the final result, is still the astronomers to discuss problems, let's look at the project content:
April 5 solstice 14, 2017, the horizon horizon telescope team hope that by trying to get a first picture of a black hole horizon to test the basic theory of black hole physics.Through connect global array radio telescope in together, forms of telescope, the size of A huge earth, using A known as very long baseline interferometry and aperture synthesis technology of earth, we will enter the core of the Milky Way, observation of Sagittarius A Numbers for SgrA * super massive black hole.
astronomers know that there is a dust and gas coiled around the black hole.The light will be in the gravitational field of a black hole deformation.Its brightness and color have a great help for observation.Astronomers hope to see the event horizon of a telescope is a bright crescent rather than disk.They can even see a black hole horizon shadow, in the heart of the glitter.
this time plan array to connect the Antarctic, Chile, Hawaii, Spain, Mexico and Arizona nine earth observatory's radio telescope and all other series."Virtual telescope" have been developed for many years, the technology has been measured.However, the test shows the initial limited sensitivity and resolution is not enough to detect black holes required standards.But after added new telescope array, including the Chilean atacama large millimeter wave and the South Pole telescope array, will make the detection distance and resolution greatly increased.
although connected in this way many telescope is well known, but the horizon horizon telescope face special challenges.Record each site in the network will be shipped to the central data processing facilities, a supercomputer will carefully combined all the data.The weather, of each site atmosphere and telescope conditions need to careful calibration of the data, so that scientists can determine any features found in the final image is not man-made.
if the black hole of the same working principle, the black hole image will open in a new era of black hole research, and solved some big problems: horizon?The black hole's gravity and the quality is wireless?Also, how to consume a black hole?How objects are ejected?It may even be observed nearby galaxies, galaxies such as our own supermassive black hole located in the center of the local group of galaxies.
in the end, the mathematical theory combined with the theory and observation, the scientists and sophisticated engineering physics experiment, the new found that will reveal the nature of space and time, rewrite the previous black holes, the history of space, time, will be hailed as the great achievement of the 21st century.
