A whistlestop tour of our solar system

[SaturnAndItsRings]

celestia.....

[Gdayguy36]

If we could only find out how to travel at the speed of light, we'd be good.

[dpowers88]

I like that Accent is that Greek?.....lmao...well its all Greek to me =]

[g00glian0]

@dpowers88 Good one!

[nagualdesign]

Should have widened the field of view before you hit record, so the planets fit into the record window. :(

[Daty37]

hollly chunksauce! Mr. Brandon Kneecap FTW

[Blueroan123]

heyyy anyone from Mr. Ackles classs ! ahahaha i cant hear this stupid movie. its Julia :P

[BeastlyBeasto]

i like her accent

[CuuijqyMuruqdte]

WTF? That stupid retard who decided that pluto not be a planet anymore is just some jerk trying to get attention, that's how people are nowadays, fucking attention whores. He says pluto is now named plutoid? well fuck it, then he's now considered NEGROID, XD =P

[Devestato72]

I ran a marathon that was 20 light years long. I finished it in a week, it was easy.

[Blueroan123]

@CuuijqyMuruqdte lawl

[metalnat28]

LOL

They now renamed planet Pluto.

It's now "Plutoid" Or something like that.

Pluto is not even considering to be a planet anymore too.

I never quite understood the specifics on why Pluto isn't considering to be a planet within our solar system though.

But as up now, Scientists have came to the final conclusion that our solar system consist of only 8 planets.

[Xxero0]

='(

Pluto was my favorite planet.... lol

[sarahfazee]

thanks for sharing

[neoqueto]

Celestia is a cool tool for amateur astronomers and for people that want to have a nice travel through space.

[AAAAkuuuu]

I would have liked to have seen Eres! Or planet X Nibiru.

[nutier]

Very nice video from our solar system that I like ! Thank you for shjaring .

nutier

[Ownageking75]

wait... so how many planets are there in total??... i know this sounds like a dumb question, but i thought there were only 8 planets... but u also talked about some other ones.

[Slayne7410]

There is only the 8 planets in our solar system (Back in my day, we were taught 9 planets). She did talk about the various moon's such as Europa and Ganamede around Jupiter and Saturn while she ran through the planets so you might be mixing up some of those. The planet mentioned at the very end of the video was in a different solar system 20 lightyears from us.

[zizu1892]

you are mistaken! eres is in our solar system as it is this side of the oort cloud! she was on about a star 20 mlys away!

[Frosmad]

Lol? are you serious?

[johnwho922]

wow they left these comments 3 mouths ago

[2CarloManansala3]

yeah^__^

[RJL738]

More like Murcury has a trace on an atmosphere as the gases that suround it are more than a million times thiner than the Earth's. So what is a moon orbits backwards, it does not mean it was captured, can't a moon orbit backwards in peace. And yeah the nearest star is 4 1/2 lightyears away...wow. And their are hundreds of billions of stars in our galaxy alone and at least that many galaxies.

[CharlieTeague]

Apha Centauri isn't the nearest star it is actully an orbiting red dwarf called Proxima Centauri which is out shon by the two sun like stars Alpha Centauri A about 25 percent larger than our sun and Alpha Centauri B slightly smaller than out sun. These three stars form a single star like object known as Rigelkentaurus, any way Proxima Centauri is the nearest star to our solar system.

[miketheday]

Well done & informative for an update/refresher on the planets & exploration. I think some of the exploration money could also be well spent taking care of some of our own citizens here on Earth too. Why go back to Mars just because it;s there? Why not feed millions of starving, diseased People here on Earth, because we are HERE.

If you were an alien studying our little planet & our societies, wouldn't you view things a little differently? Would you ask yourself, why do they kill each other?

[dahunterfromrune]

if aliens for beyond our planet took a look at us. they would probably think were in a mission to destroy our world.

[g00glian0]

@miketheday I think we kill each other because there are so many buttholes on this planet. Not a day goes by that someone isn't trying to run you off the road or whatever.

Do you really think giving all our money to poor people would help? I don't. I think lots of people are poor because of no self control. I believe there are countless people you could give a million dollars to and it would be gone within a year. Sorry, a lot off topic.

[Vikingfan13]

the video stops playing after about 10 seconds

[itsmeholleywaters]

That means it was buffering, dumbie. :)

[sexysteph722]

very well done

[tommybrett]

let me refrace that what is planet X?

[tommybrett]

i`ve got a question about our solar system is there thing coming towards or in our solar system called nibiru?

[asadnadeem97]

planet x

[tommybrett]

i would say that the theory of gravity is right but the 2 satelites that are going out of the solar system might of been took out by a object like a comet/astroid or something like that but i would say there`s something thats pulling on to the satelite that takes it to the oort cloud

[sapoty]

"because of the runnaway WHAT effect"? Please tone down the accent a little next time otherwise the aliens wont understand ya!

[Drunkpuppy]

Yumm, that northern accent made this vid for me. Especially when she said "gripped tightly".

[joshscott911]

Nice video!!!!!!!

[1peoplesun]

shit video made by a 2 year old ?

the universe is fukin mind blowing you make it look like a pile of shit ?

[cowboybootstomp]

I never knew the Poineer probes are drifting off course! Wonder what's causing that?

Maybe they will come full circle and return to the inner solar system.

[newscientistvideo]

No-one knows! :) One idea is that our theory of gravity isn't quite right and needs a tweak. However the alternative version of gravity doesn't work either: space dot newscientist dot com slash article slash mg19426105.400. The course change isn't enough to bring them back to the inner solar system, though.

Michael Marshall, online editorial assistant

[DeadlyChinchilla]

Well, you don't drop a particularly successful theory just because you have a new problem. There are aspects of gravity we don't understand, so we may have to adapt our current theories as we learn more. It'll take time though, as most scientific truths do.

[newscientistvideo]

Oh, absolutely, I meant to say that. Obviously, one anomaly isn't enough to make you chuck a theory. It's more a question of how many diverse phenomena does the theory explain, and how many random numbers does it have in it. And at the moment gravity is doing well on both counts.

There's not enough space in these comments. :)

Michael Marshall, online editorial assistant

[DeadlyChinchilla]

Most definitely. Isn't it in Greenland, where that area actually has less gravity than the rest of the Earth, and scientists can't figure out why? Interesting anomaly indeed. But then, thats why gravity remains 'theory', because we can't be 100% certain we have it all right.  We'll see what develops!

[DJAmsterdam22]

Great Video by the way. I want to study this in college but at the moment my academics have me tied down :(

[DJAmsterdam22]

Whats so amazing to me is that we are only 1 small fraction of the entire universe. I cant help but to think that out there somewhere in a part of the galaxy where our technology cant currently reach, that there is someone looking up at there sky asking the same questions we ask.. are we alone in the universe...

[zucoy21z89]

Dose anyone have any idea when we'll have the first wormhole? I presume we need to know more of what the universe is made of. But I bet that somewere some mad scientist is having a good go!!

[BlueLikeWoah]

She is VERY Scottish.

[Nemoticon]

the saddest thing is that you guys are way critical.

[slaminbones]

and this clip tell me what i didnt know already??nothing plus yes life is out there look how easy it is to find life on the earth in the harshes conditions.why wud they want to contact us???look at what they would find war crime ect ect

[Cruithne3753]

Couldn't they get a newer image of Titan from Cassini?

Also, Alpha Centauri is a binary. Even on the version of Celestia I downloaded.

[sirtinycreep]

We as a species haven't travelled very far from our doorstep judging from this tape. It's sad about our scientific limitations...

[Guardian77777]

lol i tell you, right now, independance day is on and i tell you, if aliens have technology like the bad guys in that film, we're goners lol

[JimmyJillikers]

I don't want to sound racist or 'regional accent~ist' but somehow the presenter's way of speaking makes it seem like an aircraft evacuation procedure. Maybe get leonard nimoy to re dub it?

[davidthechef1964]

yeah just clocked it .What a crock .haha

[Flopalot]

lmfao leanord nemot owns all =)

[Stickings90]

Nearest star being Alpha Centuri??? I thought our nearest star was the Sun.

[TheKraig]

I liked the Scottish accent, unlike everyone else who's commented on it.

But yeah, if we are to 'colonize the galaxy', we have a hell of a lot of work to do. It's a shame us non-geniuses can't really help much. Or can we?

[Nintendude999]

of chourse theres other life, we cant be the only living things in the univers......can we...?

[Guardian77777]

So far, theres barey any evidence for other life except for us. But you must remember, we're only starting to explore space, would give it another 50-100 years till we reach a point where we can go far and wide with some ease. lol too bad for us, most of us will be long dead.

[puretroubleman]

Humans won't be leaving this solar system for many generations, and even then they may never return.

but we will be exploring other planets in our life times :)

[Guardian77777]

lol i wonder if we'll ever come across any planets like earth and find life.

[wibblywobbly1]

I can assure you that there is life out there, and that they are here as well. They can travel about this planet with impunity, and do. How do I know this 100%? I was just in the right place at the right time and now know. Absolutely.

[Guardian77777]

Really ? But what do they want ? I personaly reckon they are studying us, even tapping into internet sites like this and decoding our topics and comments, seriously. If there is aliens out there studying us, they are not good aliens, for good aliens would've openly contacted us.

[wibblywobbly1]

All I know is that they are here, and having an opportunity to do me harm, they never did. They are most definately surveying, beyond that I don't know.

[Newtoon]

On the other hand, if there is aliens out there studying us, they are not bad aliens, for bad aliens would've openly destroyed us ...

(or enslaved at least)

[Guardian77777]

But wouldnt they be studying us because of our technology ? They wouldnt be on a mission just to destroy us, but harness the planet for their own means and they know we have weapons strong enough to completey wreck the planet. In my opinion, if there are aliens studying us, their not looking allies.

[Guardian77777]

Is Neptune a giant water planet or is that just Blue Gas, or maybe both ? Maybe there could be life there.

[Jimmy87nottingham]

Its a gas giant, same as Jupiter and Saturn

[ZhouThien]

dang! her accent! i cant follow! hahaha

[DamDastardly]

6 manned landings on the moon?

[zaohragein]

spootnik, sputnik love

[genralbiatch]

whats a "muwn"

[k3nn7]

Interesting video, thank you.

Please press "SHIFT and +" to toggle limit of knowledge textures. This will will remove the rather ugly textures shown when looking at Murcury. :)

[newscientistvideo]

Hi k3nn7, I did think about removing the dull grey half of the planet and replacing it with something nicer. But after some thought I decided to make a feature of it, hence Valerie mentioned in the narration that we've only mapped half the planet. You could do it either way, I guess - we decided to go show strictly accurate stuff as far as possible (obviously that broke down when we got to Pluto and Gliese 581c!).

[krenmeister]

lol spootnick1 what a random name for a satellite

[willymcgee42]

I'd rather see a fat Britney Spears, or some football player getting his neck broken. Then I could leave vulgar comments... Let's package up youtube and send it out to the edge of Solar System.

[mk0001]

The next trip to Mercury is done by the Messenger spacecraft, already underway and just past Venus for the 1st time.... see messenger-page of NASA.

Never heard of the Voyagers being off course. Anyone knows some scientific articles or comments on this??

[newscientistvideo]

Hi mk0001, it's the Pioneer spacecraft (specifically Pioneer 10 and 11) that are famously off-course. The Voyagers might also be off-course, but we don't know, because the effects of their on-board rockets overwhelm any anomaly. There's more information on the anomaly, including both sets of probes, in this New Scientist article (which isn't free to access I'm afraid):

[mk0001]

Thanks

[JustyHakubi]

This was a great video. I am in love with that voice-over girl. I did not know that we had another mission to Mercury in the works. Are we going to see the hot side now? As for space travel we really need to start experimenting with quantum physics to get us around. Einstein is not going to let us go anywhere good! Quantum tunnelling my friend, LOL.

[mtvbaseplayer]

it not our theory of gravity thats wrong, when navigating thro space there are things to take into account... the gravity of the planet/moon your slingshotting round, solar winds, near speed of light particals! all of these can have a impact on navigating.

[nicguyedwards]

Hoots 'n' jings m'boab!

[FutureStyles]

gawd i hate her voice, what is she scottish?

[CalabusDabus]

spootnik

[Vehrmacht1939]

My name is Skid Marx, i come from the planet Urundies next to Uranus.

[ares213]

The narrator, regarding Pioneer 10 and 11, mentioned that our theory of gravity may be wrong.

Now, I'm no scientist. So, I'm wondering what the implications of this may be if our theory of gravity was discovered to be wrong.

[MaxSafeheaD]

Well not a lot for day to day life but it may well explain a lot for physics to capitalise on. You may have heard of Dark Matter - the substance theorised to cater for gravity anomalies we have (or had) no other explanation for.

[newscientistvideo]

Hi ares213, MaxSafeheaD and mtvbaseplayer,

The 'theory of gravity might be wrong' thing is one of several explanations put forward for the Pioneer probes going off-course. There's a way you can tweak gravity that explains the probes' movements, but it looks like it gives wrong predictions for how the outer planets move.

If you're interested, there's more on this at space dot newscientist dot com slash article slash mg19426105.400

Michael Marshall, online editorial assistant

[MaxSafeheaD]

Thank you very much =)

[dwl693]

to be honest i dont even think about space or time there are so many question's posiblitys theorys that wont be answered in my life time

[mewletter]

thus ignorance took over the arrogant and naive... It's best to get it bits of info daily for the brain. Use it or lose it.

[MaxSafeheaD]

But it's worthwhile to have some appreciation of just how many mysteries there are out there and how petty squabbling over national borders or ancient custom/religion is really, totally insignificant.

[simonpeters007]

thats if you believe its all true. I only know what they tell us, and history shows us that they lie!!!!!

[JustyHakubi]

How can you possibly think this? You are only 28. Just look at all the scientific progress in the last 50 years. Let's say that you live to 78 give the world another 50 years of progress. My god man, you are in for the greatest show. They're discovering stuff every other month it seems.

[ge0gaia]

I can't believe they mention that our ideas about gravity might be wrong. They are so right. They are all wrong!

[tabion7]

awesome vid. i don't know if anybody else feels this way, but whenever i watch stuff about the planet, i feel like the tiniest insignificant thing. Our universe is so vast, mysterious, and beautiful.

I also start feeling like death sucks, cuz you stop learning about the new discoveries that humans can perform.

[3Deity]

Since I was a small child I've been able to remember other lives, lives that psychics always pick up on. So I believe totally in reincarnation. You'll be back, have no fear! :o)

[crankyvampire]

oh crumbs making a mess of things once is enough thank you very much....

i really dont need a second go at destroying the universe xD

[PolliFaxToaster]

celestia is very fun, and its totally free open source.

[Marrtyn1]

Great Video.

I Knew quite a bit about the solar system but i never knew there os a planet with possible life already found!

[newscientistvideo]

Hi Marrtyn1, thanks for saying nice things about the video! Just thought I'd give you more info on the subject of planets with possible life.

In the case of Jupiter's moon Europa, it's theoretically possible (emphasise 'possible') that there's life in its ocean, but there's no evidence as yet. Arthur C Clarke's '2010' has some fascinating ideas on this front. (continued in next comment)

Michael Marshall, online editorial assistant

[newscientistvideo]

As for Gliese 581c, all we know is that it's at about the right distance from the star. Too close and it'd be too hot, too far out and it'd be too cold - get the distance just right (the so-called 'Goldilocks zone') and it might be comfortable. Again though, there's no direct evidence of life (and as we mentioned in the video, it looks like it might actually be too hot)!

Michael Marshall, online editorial assistant

[demise3601]

good vid.
