The New Largest Galaxy

SEA: Space Exploration & Astronomy

What is the largest galaxy? For a long time, the largest was thought to be IC 110. But since 2022, there has been talk of a new, even larger galaxy, Alcyoneus, which is said to be more than 16 million light years in diameter! But is that what's really being proposed in the original paper detailing the discovery? Not exactly, because Alcyoneus is a Radio Galaxy. But what is a radio galaxy, and if Alcyoneus is not the largest galaxy, then how large really is it?
