New Horizons reached Pluto and all mankind should stand up and celebrate because this is an incredible achievement.

Fran Bagenal demonstrates how we should all feel about New Horizons and
seeing Pluto up close and personal for the first time in history.
A lot can happen in nine years. When the New Horizons spacecraft launched, Pluto was still a planet. However, it was relegated to dwarf planet status by the International Astronomical Union in October 2006. It went from being this thing we all learned as the ninth planet to "a celestial snowball with a surface of methane ice 3.6 billion miles from the sun." But like all good stories, the story of Pluto does not end there.

New Horizons didn't actually have to travel the whole 3.6 billion miles. It got to travel just over 3.26 billion miles because Pluto is one of those strange astronomical things that every once in a while, invades Neptune's orbit like the rogue it is. And when NASA switched New Horizons into data gathering mode for the encounter which took place yesterday, it started to receive images like the one below that you may have seen on NASA's instagram:
Pluto has a heart shape on it almost as if it were welcoming New Horizons to its special corner of the universe. This also isn't a picture that was snapped at its closest approach. So more images are to come which will probably be mind-blowing-ly awesome.

Pluto has several satellites. One is a moon called Charon (750 miles in diameter) which if you know anything about Greek mythology actually makes sense as Charon was the boatman to the River Styx while Pluto was the Lord of the Underworld. As you can see below, the distance between Pluto and its moon is so wide, you could fit one whole Earth between them. I like how there's a disclaimer of (Earth just for scale, it's not really there). I guess some people might have been confused because...science. It's other moons are Hydra, Kerberos, Nix, and Styx.
Some of the tidbits that NASA has shared with us are:

1) Pluto has a much younger surface than it's battered moon Charon. This makes scientists think that there could possibly be tectonic activity on this distant dwarf planet.

2) New Horizons has gathered so much data on Pluto that it will take 16 months to receive it all.

3) New Horizons is powered by plutonium, which is actually named after Pluto. The nuclear battery transforms heat into electricity, and will keep the probe in power until sometime in the 2030's. Until then, it will just keep sending back information.

4) It has a methane and nitrogen ice cap on its north pole (at -223 to -233 degrees Celsius). It's so cold that the ice wouldn't even be slippery.

5) NASA knows its awesome: yesterday was the 50th anniversary of the first image sent back from Mars.

6) It's surprisingly bright on Pluto which should give you new respect for the power of the Sun. You can actually go to this website for Pluto time so you can go outside at the time of day when it would be the equivalent of high noon on Pluto (Hint: It's not dark). My mind is blown thinking of how a ball of fire could light up something so completely from so incredibly far away. Then again, on one hundred degree days I've often thought of how immense and powerful the sun is to make it that unbearable from 93 million miles away--that's one hell of a heater.
People, we are living in amazing times. Mankind is finally beginning to chip away at the vastness of space. We've discovered thousands of planets out there, billions of galaxies, and I just recently heard that NASA is going to Europa because they think there's a liquid ocean on Jupiter's famous moon, and they want to find out if that's true. I think we should all take a pause from our latest outrage (choose your flavor of the week: Confederate Flag, Iran Deal, Greece Bailout, Serena Williams has been body shamed, Atticus Finch is a racist, Donald Trump thinks all Mexicans are rapists) go out after dark, and just turn our eyes upward at the stars and think about how much we have to learn and how far we have come. Maybe if everyone did this, we could develop a sense of community as a species and manage to treat one another decently for a little while and stop ruining our planet.

  2. The Pluto thing is cool, and I actually put on my NASA television channel yesterday for the first time ever. (I mistakenly thought I might get to see Pluto...but all there was were NASA people talking about Pluto. And one guy holding up pictures of Pluto on paper. Seemed a little low-tech, but whatever.)

  3. Hooray we know slightly more about a rock.

    1. I suppose there are other things that you deem more important? Care to share?

    2. Climate change, income inequality, racism, gun control, sexism, etc

    3. So basically just "all the outrage" which is what I said people should take a step away from to appreciate the majesty of this human endeavor. The problems you name are unsolvable. They are here now, they are here in the future, they will be here a hundred years after I'm dead. I'm not arguing that the issues aren't important. Rather, I'm saying that we should all take a moment to appreciate something greater than the problems we create for ourselves on what Carl Sagan once called (referring to Earth) as "a little blue dot floating in a mote of sunlight." We are so insignificant in the scope of the universe.

    4. You sound like this nutjob on climate change: can't fix it, so don't bother. http://unlikelyson.com/874/#comments

  4. So fascinating. I love all the details, and seriously? Tectonic movement on Pluto? Maybe we need to reclassify it again, eh?

  5. It is exciting. The enormity of space boggles my mind. The more we learn the more there is to learn.

  6. Unfortunately, I think it's going to take more than Pluto to get space funding back on track, especially with all of these recent rocket losses.

  7. I didn't know Pluto had all those moons. It makes me wonder how big they are. I'll go have to look that up.

  8. I can't wait until they start releasing more pictures and data from this mission. There's much about the outer solar system that currently relies on theory and I'm sure scientists will find a few things that surprise them. That in turn will give us a better understanding of how our universe formed which helps us understand our own planet.

    Have you ever played the game Kerbal Space Program? I bought it a few years ago and it gave me a better understanding orbital mechanics than I ever learned in my year of high school physics. It's thoroughly entertaining as many Kerbals died on the launchpad for me to achieve this. I found it amazing that a silly little game could give me so much insight into the cosmic dance in our solar system. Steam has a demo if you are interested in trying it though I highly recommend the full version.

    1. I have never played Kerbal Space Program. You always have the most original (and insightful) comments, Kev.

  9. Pluto is a lot more cooler now

  10. Thank you for these nuggets of wisdom. I especially like the Pluto/ plutonium connection and the Charon/ Pluto/ River Styx. When you remember that the first manned rockets into space happened around 1960, humanity has made extraordinary progress in space exploration. The Hubble telescope alone is inspiring--how beautiful our galaxy is!

    What has happened (thank you NASA) these last few days really is historic: we have now seen via traveling unmanned instruments all the planets in our solar system and gathered pictures and data on them. Very good, people. Let's keep it up.

  11. And the pictures I've seen thus far are getting even better.

    It's funny how people are getting all up in arms about Pluto's "designation". Just because they've called it something other than "planet" doesn't mean that the object is less than. It's still a part of our solar system, it's still worth studying, and it still has things to teach us about all sorts of things.

    Sorry, just getting tired of all the "planet" stuff.

  12. I like the heart shape on Pluto. It is neat how we are able to look at a planet thanks to all those scientists. God bless them.

  13. I saw pictures on Google+ yesterday, but somehow missed the news. (By somehow, I mean I was in meetings all day.)

    I love that Pluto has a heart on it. :-D

    Also: Hi Mike! *rushes up and gives hug*

  14. Pluto is awesome! And the best thing about science is that when there is new evidence and information.,, we change what we think about things. People hate it but that's what science is about.
