Mystery of Black Hole
A black hole (black hole) was detected in a galaxy close to the Milky Way. Black holes are probably the twin black holes that exist in the galaxy where our solar system.
Galaxy called NGC 253 is one of the spiral galaxies that contain a lot of stars and space dust are concentrated. Since it is located in the constellation Sculptor, the galaxy is also called the Sculptor Galaxy.The galaxy is also called starbust because of the large galaxy of stars that formed in it.
Astronomers from the Instituto de Astrofisica de Canaries in Spain managed to record a second galaxy using adaptive optics instrument at the giant telescope VLT (Very Large Telescope) ESO (European Southern Observatory) in the Atacama Desert, Chile. The equipment is fitted with optical instruments and mirrors that overcome the blurring effect caused by refraction in the atmosphere so that the capacity of terrestrial telescope is equivalent to the space telescope.
"Our observations produce detailed images much more clear," said Juan Antonio Fernandez-Ontiveros. From these images, astronomers have found 37 regions that are bright in a narrow region in the center of the galaxy.
The stars are so tightly gathered in an area that represents only one percent of the galaxies.In the central region there may be formed at the birth of a very dense cloud of dust.
Furthermore, the results are combined with measurements of the wave and the Hubble Space Telescope image shows the radio wave activity is very high in the region. The researchers believe there are at the center of the galaxy emission sources such as Sagittarius A radio waves near the center of the Milky Way galaxy which is the formation of a black hole.
"We might find a twin center of our galaxy," says Almudena Prieto. The findings are published in the journal Monthly Notices of the Royal Academy's latest edition of the Society Letters.
Black holes are thought to have formed the natural mysteries of the huge star who died because of spending all her energy. When the center does not generate thrust outward, even star collapsing walls and attractive objects in the vicinity.
The power of the black hole is huge gravitational pull even in the light. The black hole of darkness and was only detected from radio wave activity and visible objects surrounding it.
Based on data from NASA, the galaxy NGC 253 lies about 13 million light years from Earth (not 11 years of light as written before). Prominent galaxy in the constellation Sculptor has a wide expanse of 70,000 light years. 1 light year is equivalent to 9.5 trillion kilometers.
