M98, M99

Discovered in 1781 the M99 (centre) galaxy has a normal looking arm and an extended arm that is less tightly wound. Floating like a cloud in the blackness of space some 50 Million light years away. The upper right of the picture gives us M98 A similar looking galaxy but from our perspective it is viewed nearly edge on. A little further at 60Mly. A blue shift has been measured at 140km per second. This means this galaxy is coming our way closing in every day. Dont panic it will still take 352 Trillion 183 Billion 933 Million 935 Thousand 630 years to reach us.
