An explosion in space detected April 23 marks the most distant, longest-ago event and object known, astronomers say.
Objects seen further away in space also appear as further back in time, since it takes time for their light to get here.
The newfound burst, designated GRB 090423, was detected by the Swift satellite, an instrument of NASA and two collaborating organizations. The 10-second burst was seen in the direction of the constellation Leo, or the Lion.
Constellation Leo is some stars as seen by the eye looks like a Lion. I have looked at it and it is very difficult to see a lion there unless someone draws it and still it is not complete, compared to Orion the soldier, with a belt and a baynet attached to it. Ha Ha. The stars are from about 36 light years to 5,722 light-years away, according to yahoo answers.
So now we have another object which is 15 billion years away. Wow!
The light waves from the burst are estimated to have been stretched to 8.2 times their original length, a factor that establishes this as “most remote gamma-ray burst ever detected, and also the most distant object ever discovered—by some way.”

This happened according to the article about 13 billion years ago. So it takes that amount of time to reach Earth. Can this make some thing happen to the Earth or the atmosphere today as it hits us?
