Radio Jets from the Black Hall of the Milky Way can point to Earth on the right

We've spent decades trying to decode our supermassive black hole, but the definitive signs can be ahead of us all.

Astronomers of the Max REDK Institute, using 13 radio telescopes, were called the Sagittarius A * (pronounced A-star), in the region, the Milky Way supermarket black hole was held. And once he cleared the sound of the shattered light, he saw that powerful radio emissions in the blast from a black rail only came from a small area, which could mean Earth's right. Research was published in Monday Astrophysical Journal And, if confirmed, SGR will release a new light on * and its radio jet.

Black Hole Blaster

Supercompatible black holes are very common in our universe, sitting in the heart of most large galaxies. Their strong gravitational fields allow them to come closer and remove the very close objects near them. And when they absorb most of this celestial material, a small fraction flips out into space through a black hole and a blast. These emissions are known as Jets, they carry Radio Waves and travel at light speed.

And even though we can find some radio emissions from SGR * on Earth, it is easier said than done. In the event known as light scattering, the particles of the stars in the Earth and the Aarg * * are spread in the sky, making it difficult to separate the stars from the radio emissions from the black hole.

Charming beam

But recently, a team of researchers was able to separate this radio emission using very long baseline interferometry – the technology that connects the large telescope to make it a huge, extremely powerful. Using 13 scopes around the world, they blocked the stray light and studied emissions on its own.

They saw that they come from a symmetric source, which lays well with the "jet" theory, because it explodes in the opposite direction from black pores. They also discovered that emissions are slim thinner than them. In fact, it is narrow, it only comes to 300 million degrees – indicating that it has a direct target on Earth.

With the draw of luck, this means we can have a straightforward view of the Black Bevel's definitionive characteristics. And do not worry about the jet that actually explodes us, because as long as we know that because of its perspective, we have not put any risk in it. If anything, it allows us to study an in-depth detail jet and highlight the mysterious nature of Sgr A *.
