en We find active Super Massive Black Holes at the centers of massive galaxies. Our Galaxy also has its own black hole at its center measuring 2.6 million solar masses. Our black hole is not active today, but we presume it was active in the past.

en There are other galaxies that are likely to be the same size as this one that have black holes of similar mass. However, their black holes are quiet -- they're not putting out the large amounts of energy we see in this one. We're left to wonder just why this one is so active.

en Studying black holes always was a primary mission of Hubble. Nailing the black hole in Andromeda is without a doubt an important part of its legacy. It makes us much more confidant that the other central dark objects detected in galaxies are black holes, too.

en Annihilation doesn't play the bait and switch of promising change and undoing it two issues later. I can pretty much give my word that at the end of Annihilation, there will be sweeping change in the Marvel cosmic universe that will impact any Marvel character that leaves the Earth.
