Re: [humanism-174] Check out Hubble spots a colorful lenticular galaxy

Sometime next week! lol
Actually, our next transition will be in some 4 billion years or so when the Andromeda Galaxy finally collides with the Milky Way.  The two will pass through each other and then gravity will cause the two to circle each other like wary beasts at a waterhole, and then eventually coalesce into one galaxy, with a likely elliptical shape.  That dance will take more hundreds of million years!  Without this collision, the MW might have aged gracefully and then began a transition to a lenticular shape.  Without knowing for sure, I presume that NGC5010 does not or did not have any similarly-sized neighbors as we do!
 
What is kinda cool is that our sun has at least another 5 billion years left of its life as a hydrogen-fuser before expanding to a red giant and burning the Earth to a crisp, so we should have a billion years or so in which to enjoy the collision between Andromeda and Milky Way.  I'm setting my calendar for the event! lol

Beautiful! I wonder how long before our own galaxy reaches this transitional phase?

NGC5010 is a galaxy 140 million light years from us.  The aging galaxy is transitioning from spiral to elliptical.  A super photo thanks to the Hubble Space Telescope!
