Earlier approximation 150000 ly across is currently revised to 130000 ly.
Explanation:
The precision in the measurements in ly is now limited to 2 significant digits (sd) only. !5 became 13, in 10000 ly as unit..After confirming these digits, the march would be towards lower-valued sd, using further advances in theory, instrumentation and technology.
