Dont know why it is deleted but looks unusual, roche limit around galaxy debate proof?

Continuing the discussion from Interesting object: @Ed-In-The-Couds if you found this cool proof roche limit around galaxies, you decide to post it but then delete it? just wondering why

There is a pencil up at the top of the image, it allows you to view if posts before being edited or deleted.

[William]

Uhh. that is scary… why can the pencil allow you to edit posts, is it there for a reason, feature?

[ChrisSnell88]

I think it is just a feature.

It appears that NGC 922 was published this year about that stellar stream, obviously i would confirm it
