Black hole's heart still beating...

The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed.
X-ray satellite observations spotted the repeated beat after its signal had been blocked by our Sun for a number of years.
Astronomers say this is the most long lived heartbeat ever seen in a black hole and tells us more about the size and structure close to its event horizon—the space around a black hole from which nothing, including light, can escape.
The black hole's heartbeat was first detected in 2007 at the centre of a galaxy called RE J1034+396 which is approximately 600 million light years from Earth
That's really amazing for this help. But, I would like to tell you that I have been working for online medical services where I get to know about pcb x ray inspection. You can also try to get help with these by visiting our website.
