South African scientists have revealed the clearest image ever taken of the center of the Milky Way occupied by a huge black hole, thanks to a new radio telescope called MeerKAT
"The Center of the galaxy was an obvious goal: unique, visually striking and full of unexplained phenomena, but it is also notoriously difficult to be photographed with radio telescopes, "said Fernando Camilo, chief scientist of the South Observatory African radio astronomy (SARAO). in english)
— Infrared, X-ray and radio waves —
The center of the Milky Way is 25 000 light years from Earth behind the constellation Sagittarius and is constantly enveloped in clouds of gas and dust, making it invisible from our planet to normal telescopes.
However, infrared technology X-rays and adio waves can penetrate the obstacles and "open a window" to the black hole of 4 million solar masses (a solar mass is an equivalent unit of measurement to the mass of the Sun) located in the center of the galaxy.
The image is published today in Huiparl's team of African-hardcover companies a thousand light-years away by 500 light-years with a clear region at its center corresponding to the center of the galaxy.
The first days with the MeerKAT and many remain to be optimized, we decided to go there and are surprised by the results, "said Camilo, according to the text released by the SKA Africa project, dedicated to the construction radio telescopes.
which is part of the MeerKAT, is a project involving eleven countries – Germany, Australia, Canada, China, Holland, India, Italy, New Zealand, United Kingdom, South Africa and Sweden – and to which twenty others collaborate, including Spain.
The objective is to build the world's largest radio telescope in Australia and South Africa, capable of capturing images with a resolution 50 times higher than Hubble one of the most major scientific and technological challenges The MeerKAT, whose construction lasted a decade and is one of the forerunners of the SKA, was officially inaugurated today at a ceremony in the presence of the vice president of South Africa, David Mabuza, and operates from the semi-arid region of Karoo, in North Cape Province (Northwest)
He is currently the most powerful telescope in the hemisphere south of the planet and has 64 parables of 13.5 meters in diameter each.
