ScienceCasts: Alien Matter in the Solar System

Visit science.nasa.gov/science-news/... for more.
"Alien matter" detected by a NASA spacecraft orbiting Earth shows that the chemical make-up of our solar system differs from that of the surrounding galaxy. Researchers discuss the possible meaning of this mismatch in this week's ScienceCast video.

[@educatainment1799]

We've actually known for a while that different solar systems have different ratios of elements because we know that different molecular clouds throughout the galaxy have different ratios of elements. And that is where stars form. The surprising part is that the region of space just around us could have a different chemical composition. Unless, as the video said, there is some mechanism that prevents us from getting a proper sample of the makeup of the interstellar space in our vicinity.

an object in motion will stay ion motion, even if the battery dies out it will still reach the star if the direction is exactly correct and doesn't have any interference on the way

[@Dyslexic-Artist-Theory-on-Time]

Yes! Based on just one equation (E=ˠ M˳C² )∞ the Lorentz contraction of space and time is between the energy and mass. The greater the energy the greater the contraction of space and the slower time will run. Mass will increase relative to this and each ref-frame can be seen as a vortex in space formed by the rate that time flows. The brackets represent the boundary condition of the ref-frame formed by the energy and the infinity symbol represents an infinite number of dynamic ref-frames

Actually, grun blau's grammar and sentence construction would be great in Germany. (Except for the missing full stop at the end.)

[@IAMTVWorld]

aliens came left kim kardashian in our planet :P

[@Hunnah0055]

so this could mean that different solar systems can have different composites of neons and oxygen and the space outside these solar systems has a more scattered and light composite of material. Wouldn't that mean some systems can have even more oxygen than our own and others may not?

[@santiago_307]

Its incredible that so many things are combined in favor of human life in earth. Magnetic field from the sun, the earth's magnetic field, the Jupiter's gravity diverting comets to avoid earth, etc etc. I dont think that we could find another planet with the earth's same conditions.

[@pcred567]

Okay, that wasn't at all my question. I asked about what is making it accelerate (well, aside from external things like solar wind). What I meant was that I wanted to know HOW the battery was making it move faster. I was pretty sure that the only reason for the battery was so that it could send information.

[@CaneFan25]

We are learning more and more t an alarming rate....imagine what it will be like 100 years from now!

[@deadmanzen]

What mix of items did we start from, if new material is able, are we the new stuff as dated or the old stuff, shall we change...

[@icore8515]

once it has a certain velocity, it will continue to move with that velocity and will not stop until it collides into another object, or is pulled by a larger object's by gravity (highly unlikely, unless the object is the size of a planet or if its a black hole, who knows) the battery that they have on it is only used in order to have it accelerate. it will continue to accelerate until the battery runs out (12 years as you stated).

[@lesg334]

Good Luck Voyager 1 & 2!!! Remember Veeger? Soon to really go where no one else has gone before...

[@ahm_767]

LOOOL the DC-10 that released that IBEX probe was an ex-Japan Airlines plane XD

[@alttplink]

Lol.

[@HIMI2003]

THANK GOD FOR PEOPLE THAT FIGURE THIS SCIENCE AND NATURE STUFF OUT. AMAZING

[@jaht3z]

Probably not. "Out there" is still pretty close by, galactically speaking. The Voyagers are only now crossing the boundary between the Solar atmosphere and interstellar space. They are still at least 4 light years away from the nearest star.

[@Dyslexic-Artist-Theory-on-Time]

Sounds logical!

[@MarlonBrando420]

It leads me to believe other solar systems that are very very close to us may have the same type of oxygen levels. They didnt say if it may have effect on the possibility of life.

[@H8edsinclair]

I concur m8

[@Creamagination]

Guys what do you know about plante X? AKA niburu?

[@Designandrew]

Voyager. 40 years on and still going strong. They sure don't make them like they used to!

[@henryramos4586]

thank god

[@xe2ac]

Great info!! obviusly this is not for the closed mind people

[@CaptainOfGames]

Actually it's just right outside the solar system. The nearest star is 401.000.000.000.00 km away. And Voyager 1 is 18.491.989.617 km away. So it still has 40.081.508.010.383 km to go. (If it were going the right way). It travels 3.768.950.00 km a year. So it will reach the nearest star in 106346 years. But the battery will die out in 12 years.

[@icore8515]

cont heres another way of thinking about it, an asteroid in space will travel at the same speed until a force acts on it, correct?, lets say the asteroid got caught in the gravitational force of a black hole, or a sun, etc. the gravity will cause it to accelerate (positively or negatively depending on location and direction), the thrusters will accelerate the satellite until it runs out of fuel, which then will continue to move at the speed at where the battery died. its VERY hard to explain lol

[@KeizerPaPa]

Figure this, if there is less matter per m3 why would they expect a bow shock to even be present. Bow shock is from one force pushing against a resistance force and I don't see how a stronger vacuum would produce this effect. If the data here is accurate (and I really like the O8 guys, priceless) I am inclined to say you won't find a bow shock at all. and so I would also think e oxygen is created here in our system, we'll refer to it as the O system and the O8 system as the combined k? But while talking strictly of the lesser would we call it just o... ?

[@pcred567]

That's alright. =P Thanks for the answer, BTW. XD

[@Str33tSupra]

40 years lol.. such a long time

[@ISamuelII]

@ISamuelII How did I get the b= typo in that? lol Typing in the dark with a black keyboard.

[@VerumAdNauseam]

If extraterrestrials are anywhere near the Voyager spacecraft, it's because they've discovered Earth and we're all screwed.

[@302yongestreet]

that's true :) .

[@rjshhooba6624]

I am still waiting..

[@icore8515]

it will continue to accelerate until the battery dies out, theres no friction, air resistance, gravity in space, so there is no force that is going against it.

[@MrKorrazonCold]

"Wouldn't all these particles absorbing and re-emitting EMR or light spherically distributed about intergalactic space, 13.7 billion Light Years squared, have an impact on our range of perception as the incoming light will be blocked out by the interference of the absorbing and scattering wave-medium density. Thus, the limited range overlapping spherical in+/-out wave's causes less wave interaction's with distance. Thus, Less energy exchange with distance and Doppler causes a Red Shift."

[@HORRORTV1]

And adding only oxygen could also be lethal for a human.

[@seapeddler]

For all its' technological sophistication. I doubt that Voyager could withstand the intense pressure of a local supernova. It would be blown back into the solar system. This would damage the transmission gears.

[@pcred567]

How does it accelerate? I figured the battery was just to power the components that send information back to Earth. What kind of electrical power could propel it in space? >: /

[@pcred567]

Well, the death of the battery won't suddenly stop it from moving or anything. =P

[@DaBamBamMan]

@kargenlewis It kind of is a huge mystery tho lol.

[@BekaMamukashvili]

@PointsNorth1 it was good joke from you :)

[@Reconseal4050]

so once it exits the heliosphere will it stay be able to communicate with NASA satellites?

[@zambotwu]

Not all.

[@aullaralaluna]

I wanna know who was thinking aliens floating in the space air while watching this video.... I really was hoping for some ufos :(

[@Hunnah0055]

lmao!

[@isaacopyrchal8754]

Oh, and by the way how did I bash anyone?

[@icore8515]

k, imagine throwing a baseball on earth, it eventually stops and falls to the ground, now if u throw a baseball in space, it will continue to go at the speed that u threw it at infinitely until it collided with something or is acted upon by another force, now if u added a jet engine to that baseball, it starts off with the initial velocity it was launched at, and then the force of the thrust will be pushing it forward faster and faster,

[@WeirdWolfGaming]

What if within a universe trapped oxygen enough to sustain breathing out of a planet.... I have no clue how that would work, but I am also lacking sleep so...

[@isaacopyrchal8754]

Your the scientist, please explain to me through science how someone can see when light can't enter their brain?

[@Operations1000]

Omg Voyager still exists out there!! I wonder if alien civilizations have detected it and are loling at it yet.

[@ErikSaetherExplorer]

Additional oxygen might be an indicator that life exists in a solar system. I.e. released from photosynthesis.

[@TeamDreamAway]

science saves

[@icore8515]

OH lol thats what ur asking for lmao, well if the thrusters are using the batteries, then poof, battery consumption... otherwise if they use fuel (most likely hydrogen) then the battery is probably only used to transmit data between satellite and earth lol sorry for the confusion

[@isaacopyrchal8754]

I don'y really know what you mean by trolling, your comment caught my eye so I replied, really didn't expect to have a conversation. I just stated the truth as I have experienced it. I respect your opinion, honestly, and I am not trying to convert you. But I have experienced the supernatual, what is your opinion on that?

[@ethanike]

We all have imaginary friends, I just grew out of mine and turned to science:)

[@TushantMirchandani]

And by the time it (probably) reaches a planet with intelligent life, crash landing in the middle of some Uncle John's farm, there'll be another wave of alien panics in that civilization, as they look up, wondering when flying saucers will appear and abduct them. All the while THEIR scientists also start wondering if they are alone in the universe too. (Because they haven't noticed any signs of us at all through their Bubble Telescope -- which is probably Hubble tele's evil twin.)

[@isaacopyrchal8754]

I understand,I really do. You may not beleive in Him but He beleives in you!

[@garyrector7394]

Like so many other such science videos and information posted on Internet sites, this one also presents theoretical models as though they were already proven fact. For example, some of the "facts" about the heliopause have turned out to be incorrect. I think it would be much more helpful to students and others seeking scientific information if these "experts" were clear about what is still theoretical and what has actually been shown to be true by direct observation.

[@Redkurtain]

Man seems to go to such great lengths to deny our universe's intelligent design.

[@pcred567]

Yes, I know all of that already. Acceleration in space, blah blah blah. Simple. I was asking what mechanism the batteries use to accelerate the spaceship. Obviously, they're not burning anything, and having something like a spinning blade won't work at all in space due to the lack of atmosphere. So I'm asking you, WHAT COULD THE BATTERIES DO THAT MAKES THE SPACESHIP ACCELERATE? =P

[@HORRORTV1]

But you'd freeze to death.

[@ethanike]

but until then no proveable*

[@TURUKMAKTO420]

SPEAK THE TRUTH NASA WHAT IS GOING TO HAPPEN ON 2012 21 12, TELL THE TRUTH OF WHAT IS GOING ON !!

[@ethanike]

Trolling is so last year. Come on now.

[@Mouskell]

You're in the wrong habitat, dude.

[@fabmd8]

@Designandrew That 40 year old Voyager is amazing, indeed! They must have hired the same engineers who build my Kenmore washer. Why? When I moved into my house, I brought my '98 Whirpool washer with me. I found that I had a choice of using it or the 1955 Kenmore washing machine that was left behind. I chose to use the 1955 Kenmore model (despite a little rust, the color) and sold my much newer white Whirlpool. I have been using the 1955 Kenmore washer ever since without problems.

[@isaacopyrchal8754]

I'm sorry your offended, but I never once mentioned the Bible. By the way personal attacks are very immature

[@Bucboy1001]

We have yet to find an old man dressed in white robes living on a cloud, we'll be sure to let you know if we find him though.

[@sonnygirl2010]

5 people don't understand the lingo!!!

[@isaacopyrchal8754]

What if I told you about a child, a girl that was born blind because she had no pupils, was prayed for by a very holy and devout man, a man that bore the stigmata for many years, all of a sudden could see as well as you or me without any type of medical procedure at all? And I could prove it, what would you say about that? By the way she still has no pupils! Impossible right. NOT... True story, and, like I said, I can prove it!

[@mrmapegothe13th]

Not to get into a religion war here, but people do know who wrote the bible, and when they say that its only 6000 years old you have to consider they used different time periods than we do. For example whereas we have a year as 365 days they could think the same amount of time was equivilent to a half a year. Etc. You have to understand that during the time it was written people used much symbolism and much of the bible cant be taken literally.

[@isaacopyrchal8754]

How you can look at all of this and not beleive in God is beyond me, He loves you unconditionally

[@ethanike]

How you can look at any of this and believe in a god is beyond me.

[@alttplink]

Why can't Christians use grammar?

[@josemedina-jm4od]

jjjjjjjjj

[@SIMKINETICS]

Why can't muslims use grammar?

[@PointsNorth1]

I have the answer - god/s did it! just joking.

[@ethanike]

There is nothing that I typed that said i was a scientist. I asked you a question.....and specifically asked you not to change the subject....and you did hahah. How did I know you were going to do that? I'm not answering you until you answer me. I'll ask again, prove to me that it was god who made her see.....You made the claim and said you could prove it.

[@isaacopyrchal8754]

I said that I could prove this person was born with no pupils, was prayed for by a holy man, had no medical procedure, and now can see as good as you or me, and still has no pupils. That may not be proof of God to you, I would like you to expain how it could be anything other than a miracle.

[@isaacopyrchal8754]

Why are athiets such angry profane people?

[@ethanike]

No let me reiterate. Do what I asked of you first. Prove how you know visibly and with evidence that it was god who made her see....don't change the subject...just answer that....

[@ethanike]

I would never presume to tell you that the experiences you have had weren't real...to YOU. But until there is no proveable eveidence that the celestial or the supernatural exist. The only magicians I know of are at birthday parties. I'm sure what you experienced FELT real to you, but my equal experiences have told me that everything that I though was supernatural could be easily explained without chalking it up to "God did it.".

[@TastyGamingQc]

Because you're preaching intolerance and ignorance which is the total opposite of science.

[@ethanike]

You seem to make alot of assumptions in your life based on no evidence. It must be a very confusing life for you. "God is working in mysterious ways! We don't know his powers!". I hope you get over your illness, I hope that all religious people will one day think for themselves. It doesn't look to good for you guys...I think you have just as much evidence on traumatic experiences as you did for the little girl. Which is next to none. I'm sorry, but when you die...the lights just go out.

[@josemedina-jm4od]
