It's also accelerating some cosmic rays to near the speed of light.Rays Banned

A team of Chinese researchers has discovered a mysterious barrier that appears to be stopping cosmic rays from penetrating through to the center of the Milky Way. Even more strangely, the same region seems to be accelerating these rays to blistering speeds.

The research underlines just how difficult it is to get a precise reading of what the hell is going on inside the swirling ball of excited cosmic rays that makes up the center of our galaxy.

Highly energetic events such as two galaxies smashing into each other, or objects like supermassive black holes, spew out storms of cosmic rays,which essentially amount to protons. These rays often are accelerated to almost the speed of light by these events and celestial objects,which interact in fascinating ways withour galaxys magnetic field, which appears to form them into whats referred to as the cosmic sea.

Scientistsworking theory is that theres a supermassive black hole, called Sagittarius A*, sitting at the center of our galaxy, where it whips cosmic rays into a whirlwind.

In their paper published this week in the journal Nature Communications, the team found that some of these rays were unable to push their way past a dense barrier and enter a central molecular cloud of interstellar dust and hydrogen gas known as the cosmic ray sea.

The team used data collected using the Fermi Large Area Telescope, a space observatory that analyzes a host of cosmological phenomena including gamma ray bursts and solar flares.

Other rays that werent entirely stopped by this barrier first slowed down and then mysteriously sped up again as they passed through the central cloud, leading the researchers to believe theres something like a particle accelerator at the galactic center.

The most apparent answer for this acceleration would be the existence of Sagittarius A* but the team wasnt able to come to a definitive conclusion, nor rule out other possible explanations, including the remnants of a supernova.

In other words, thereare still many questions when it comes to our galaxys turbulent center. This newresearch just goes to show just how much there is still to learn.
