Namita PearReverend TZWAbout 1000 Lys out from the bubble heading for the Formidine Rift,
It's possible that streak of light is a line of bright stars, B-class perhaps. I noticed a similar phenomena with the NGC 7822 nebula (near Elephant's Trunk), which has a burst of B-class supergiants tightly together that looks like a streak until you start getting very close.
The only real way to find out is to start jumping towards it though!
That’s what I thought but it is way beyond the Formadine rift and, as far as I could make out, beyond the Perseus Arm. Which means outside our galaxy I assume
PS, looks like my memory was faulty. It wasn’t thousands of galaxies at all!
‘100 billion galaxies
All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.19 Mar 2018’
