In this particular case, yes, before the Sun formed as well!

It’s a good question! You’re right that a single star wouldn’t cause that, but the distribution of stars in galaxies tends to be more centrally concentrated, so more stars = more light. It can be a steep change, which resembles an edge. The details depend on the galaxy, but it’s a common feature. 🔭
