1900? Humm.
I understand what they are saying but it happened a lot longer ago then 1900. Its expanding at 5% the speed of light an its about 26,000 ly away from us so its a bit more then 140 years old.
I know they say "(referring to when events are observable at Earth)." but it seems to me that for a general public press release they should make it crystal clear that the light finally got her 140 years ago.
Don ch tnk
