Black hole Makes two bubbles!

A few days ago the NASA telescope saw two bubbles(gamma ray bubbles) that were 25,000 light years NORTH and 25,000 SOUTH that were made by a black hole and it was found in our galaxy(not universe)  
And if you don't know how much a light year is,1 light year is 10 trillion KM or 6 trillion MILES,but think of 25,000 light years,like even 25,000 Km is a lot, but multiply that by 10 trillion is like HUGE
They also said they don't know much about them.And they also said it might be 10 million years old!!!!
They are also trying to study how it was made.And to travel that distance it would take you a trillion
