Pluto is dead. Long live Pluto!
It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn’t feel like a giant. I felt very, very small.
Neil Armstrong
You know, recently I found a picture of the Blue Marble and it quite frankly stunned me. I mean - how beautiful is that? Not the follow ups created from satellite pictures. Undoubtedly they’re beautiful as well, but this “original” picture just gets it right. (High resolution picure is about 6 MB big.)
By the way, Neil Armstrong wasn’t on that mission, I just liked that quote..
On another (and far more current) note: Pluto isn’t regarded as a planet anymore. And rightly so. Small, cold, far away.. who wants him/it/her(?) anyway? So due to some wish to not entirely abandon it (along with Ceres and 2003 UB313) they created the new category of dwarf planets and set up three rules required for the status of a planet:
- it must be in orbit around the Sun
- it must be large enough that it takes on a nearly round shape
- it has cleared its orbit of other objects
Especially the third rule is promting quitew a bit of dissent according to the BBC. We’ll see what comes from all those protests. And to be quite frank: I don’t believe that this naming discussion will change the way astronomers work very much.
