This article is strange. Any possible explanation will do.

It was a spark in the night. A flash of X-rays from a galaxy hovering nearly invisibly on the edge of infinity.

Astronomers say they do not know what caused it.

The orbiting Chandra X-ray Observatory, was in the midst of a 75-day survey of a patch of sky known as the Chandra Deep Field-South, when it recorded the burst from a formerly quiescent spot in the cosmos.

For a few brief hours on Oct 1, 2014, the X-rays were a thousand times brighter than all the light from its home galaxy, a dwarf unremarkable speck almost 11 billion light years from here, in the constellation Fornax. Then whatever had gone bump in the night was over and the X-rays died.

I'm still trying to fathom the distance of 11 billion light years away!

It means that the source of the light you are seeing may not exist any more!!!
