Added 2 new A* pages:Hey look, it's the largest known galaxy (on the left, in X-rays, and on the right, in visible light at the center of the Abell 2029 galaxy cluster):|

This "supergiant" galaxy just over 1 billion light years from Earth is known by the unflattering name IC 1101, and is about 5.5 million light years across (the Milky Way stretches a mere 100,000 light years), containing an estimated 100 trillion stars (we've only got 0.25 trillion here). Great! It's also pretty boring looking in these blurry photos, but then these blobbish "lenticular" galaxies don't tend to have the pizazz of a nice spiral galaxy when seen from afar. But it's really big, so huzzah for IC 1101.
Hmmm I wonder how big a black hole it might have at its center? And would they have to invent a new name for one that size (assuming its relatively big), like "supermassivegiant" or something?
