Researchers found near Milky Way black hole

Huge black holes might hide behind clouds of gas and dust in our cosmic backyard, writes British newspaper The Independent.

Astronomers have found evidence of the existence of black holes in extremely high center of two galaxies surrounding the Milky Way: NGC 1448 and IC 3639. Now they are increasingly convinced that the biggest galaxies have black holes means such, but they are hidden.

The two galaxies emit strong radiation and are considered active, but is far from Earth, one in 38 million light years, and is the other 170 so huge black holes are not yet a threat to our planet.

How does a black hole

A black hole forms when a massive star runs out of fuel and collapses into it. Then it produces a supernova, throwing into space part of the star’s matter. The gravity of this “death star” is so strong that catch the light like a trap and distort space and time. 

Black holes can only be detected by analyzing the latest emission radiation of objects that you swallow. Astronomers from Durham University have discovered black holes in nearby galaxies using a powerful X-ray space telescope launched by NASA in 2012, called Nustar – Nuclear Spectroscopic Telescope Array at.

One of the team members, astronomer Ady Annuar said that these black holes were not detected before, but they are relatively close to the Milky Way: “They’re like monsters hiding under the bed. Now we wonder how many other huge black holes might exist around us, without us knowing. “

Scientists bănuaiu long that super-massive black holes exist, but they could not be detected before. But using Space Telescope clearly shows these hidden monsters, explained research team leader George Lansbury, the Centre for extragalactic Astronomy at Durham University in Britain.

Nustar is the first space telescope capable of creating images of cosmic X-rays with high energy, the same rays used in medicine to view the skeleton or to scan luggage at airports.

The telescope produces images with a resolution 10 times greater resolution than previous images obtained with telescopes and is 100 times more sensitive than these.

Nustar can capture high-energy X-ray even beyond the dust and gas that obstruct observation of galaxies, black holes and neutron stars in both the center of the Milky Way and neighboring galaxies.
