Pluto Update!!

Posted October 07, 2015 7:48 AM by Bayes

The Data Keeps Rolling In...

It's been 85 days since NASA's New Horizon's space craft had it's closest encounter with Pluto (and Charon) and the data from that encounter keeps coming in and will continue to arrive for years to come (it's a lot of data). Here are some choice images from the encounter:

Pluto - Cold. Very Cold.

Charon is impressive itself:

The contrast between Pluto and Charon is striking!

Pluto has more atmosphere than expected. And younger geological features!

More Coming...

Amazing pictures. Just f'n amazing. When I was a young astronomy buff with crudely built telescopes, Saturn was about the limit I could achieve in my back yard. This totally blows my mind.

It's interesting the relative size of Pluto and Charon - it's more like a double planet than a planet and a satellite. I'm sure that the center of gravity is well outside Pluto, so what a relative movement they have! The implied tidal forces might explain the younger then expected geological features of Pluto.

When I first saw that picture of Pluto, I was struck by how much sense it made. It truly looks like a very, very cold ice ball.

I read today that Pluto has blue skies...

"On Pluto, 33 times farther from the sun than Earth is, light from our star is scattered through layers of atmospheric haze in much the same way - except there it's not by molecules of oxygen or nitrogen but by very tiny soot-like particles called tholins."
