But trillion years from now. our supercluster (virgo supercluster) may form a supergalaxy.

Supergalaxies can be galaxies that are larger than the Milky Way... lolz...

But Milky Way and andromeda colliding will make that future elliptical, merged galaxy called Milkomeda.

The one in the middle looks like a picture that's taken through a normal telescope on Earth. It looks a little bit like the Whirlpool Galaxy, my favorite.  |

Two supernovae have been identified in M74:[2] SN 2002ap[7] and SN 2003gd.[8] SN 2002ap has attracted considerable attention because it is one of the few Type Ic supernovae (or hypernovae) observed within 10 Mpc in recent years.[9][10][11] This supernovae has been used to test theories on the origins of similar Type Ic supernovae at higher distances[10] and theories on the connection between supernovae and gamma ray bursts.[11] SN 2003gd is a Type II-P supernova.[12] Type II supernovae have known luminosities, so they can be used to accurately measure distances. The distance measured to M74 using SN 2003gd is 9.6 ± 2.8 Mpc, or 31 ± 9 million ly.[3] For comparison, distances measured using the brightest supergiants are 7.7 ± 1.7 Mpc and 9.6 ± 2.2 Mpc.[3] Ben E. K. Sugerman found a "light echo" - a reflection of supernova explosion that appeared after the explosion itself - associated with SN 2003gd.[13] This is one of the few supernovae in which such a reflection has been found. This reflection appears to be from dust in a sheet-like cloud that lies in front of the supernova, and it can be used to determine the composition of the interstellar dust.[13][14] -Wikipedia http://en.wikipedia.org/wiki/Messier_74 |

NGC 2535/2536 are both interacting galaxies.
