Question: What is the youngest galaxy

Well it depends how you look at your question, the youngest are being born right now! But the youngest in terms of what we can see closest to the start of the universe would be Abell2744_Y1 which we are seeing as around 660million years old but in reality it’s actually closer to 13billion years old, we are just seeing it when it first came to be after the big bang!
