…Colossal explosion from supermassive black hole at center of galaxy.

From the blog KurzweilAI, the AI standing for Artificial Intelligence.

Two million years ago, a supermassive black hole at the heart of our galaxy erupted in an explosion so immensely powerful that it lit up a cloud 200,000 light years away, a team of researchers led by the University of Sydney has revealed.

What about the event horizon?  What will be the impact on Earth?  How fast is this thing traveling?
