An Active Galactic Nucleus (AGN) Indicated here by 2 lines
5 billion light years away (5,000,000,000)
My personal distance record
Letters mark reference stars of known magnitudes, for measuring the AGN's variable brightness
The object marked by the two lines looks like a star. Professional astronomers have examined the spectrum of its light and concluded that it is about 5 billion light years away.
That means that I have captured in my camera some light that was emitted before the Earth was formed - a staggering thought!
