ESOcast 167: VLT sees `Oumuamua getting a boost

[@climbergreen_]

They didn't mention here that this "comet" has density approximately 6.5 g/cm^3 which is abnormal density for ice and rocks. Of course if they calculated it correctly. A superconductor like vanadium-gallium has the same density.

[@klakier19901]

6.5 g/cm^3???? That's almost like iron!

[@energyduoprudoction195]

Ur smart

[@fuckednegativemind]

climbergreen I don't know where you saw this, but it's absolutely wrong. We can't constrain its density as precisely, even if it seems to be high (nothing anomalous), this number is bogus.

[@spunn_co]

It's not a comet this dude is an idiot.

[@climbergreen_]

@@spunn_co there is only one idiot here and it is you

[@Shylockza]

Whatever they tell you, they're lying. It accelerated out of our solar system under it's own power. It was not a comet. It was and is something much more -> interstellar self propelled vehicle. Why have they NEVER shown us the exact item, it's always an 'artist's impression".

[@zabaziomalka]

our best OPTICAL telescopes are still too slow and too far away to catch that fast things. All you eventually will be able to see on that kind of image, is a small dot, not different from the stars in the background.

[@racksityentertainment]

Some may don’t remember but several cigar shaped celestial object were observed

[@giuseppegatani704]

'Oumuamua fascinate from the moment of its discovery and it will continue to fascinate us!

[@stephendean2896]

When I came to this solar system I tried to leave faster than I came as well But I lost my momentum so that's that

[@Bounty_Kxlla1]

Why aren't there any real pictures or footage of it?

[@keshov7945]

bruh..

[@botaine]

does outgassing a little for only a few days produce enough force to change the trajectory that much?

[@Corruptedd]

I'll tell you one important thing about outgassing..... *FART SOUND* LMAOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

[@funny-video-YouTube-channel]

*Wonderful discovery.* This asteroid torpedo is very interesting. It might be a space ship, it might be an unusual fragment from a mining colony of aliens. In any case it's a very interesting object category that we can study, if we see more of them.

[@riverocean4380]

Harvard Could 'Oumuamua be an extraterrestrial solar sail? phys.org/news/2018-11-oumuamua-extraterrestrial-solar.html

[@bar10dr]

Didn't they say it was spinning fast? If so, wouldn't it be outgassing in all directions equally and thus would not outgas in its exit direction while leaving the system?

[@Corruptedd]

Yes, it may just be that you are *GENIUS* (not sarcastic)

[@alexa.davronov1537]

That's quite scary that such a the piece of rock can enter solar system from nowhere and leave by the same way without any prompt. It can destroy literally everything in a moment. May be it worth to observe the place or direction where it came from to find more new ones?

[@JeffersonHunter]

We don't know where it is coming from. We tried to find out, and discovered that it had changed its speed...

[@furkatfz]

The question is if the energy this object gets from Sun with radiation is comparable with that needed to boost it?

[@JeffersonHunter]

It is. Also, the additional boost is getting weaker the further away it gets from the Sun. As it should.

[@furkatfz]

Thank you! But the imagination draws a picture that few weeks later we''ll see a bright flash in the sky - the crew starts the engines :-)

[@MrTryAnotherOne]

Shouldn't Oumuamua have decelerated when it outgassed as it approached the sun?

[@JeffersonHunter]

It should have - but it wasn't observed when it was on the way out f the Solar System.

[@ranfordflemings7723]

I wish they would show us the actual image that they saw, this is only a rendition of what they seen. Show the World what you SAW and then we can began to have this conversation. Why are they hiding this actual image from the world should be ALL of our Question today! Shalom!

[@SkywalkerWroc]

open MS paint, fill it with black, then use white brush to paint white dot. That's what they see, nothing special to "begin to have this conversation". A lot of data can be obtained without having quality photographs of the object.

[@JeffersonHunter]

[@vchirayil]

Estimating shapes of asteroids/ comets, based on their lightcurve is pseudoscience & Oumuamua is an outstanding example of this ! The sensational cigar shape is pure rubbish, as explained with proof, in a video called "Oumuamua - Rubbish Shape Estimate", on my channel. I would love to hear an intelligent rebuttal from folks who blindly believed the cigar shaped bullshit. I am not aware of anyone who challenged the ridiculous shape estimate of Oumuamua. The world just went along sheepishly with the peddled story. By the way, why does ESO depict a white sun as fictional yellow / orange, just like flat earth idiots do ?

[@flyingjunkies]

There's a TED Talk video about this and they show the real picture

[@vchirayil]

Flying Junkies ... the best instruments saw a tiny dot of light. thats all. on my channel i explain why the shape estimate is total bullshit.

[@dysonsquared]

Wouldn't it have *already* outgassed when it was closer to the sun? Hmm, curiouser and curiouser.

[@JeffersonHunter]

It would. But you need very very accurate data to find these subtle changes in speed.

[@framkey]

Very interesting video. I’ll let the experts battle it out and decide whether it’s space rock or extraterrestrial; either way, it was a well made video and gave food for thought. Thanks for sharing. 😊

[@vanessagarza2774]

Our Solar System probably got Reconned on!! It could of been an Interstellar spacecraft "Camouflaged" as a comet or asteroid (whatever they decide to call it), it came gathered some Reconnaissance from our Star (Sun) and nearby planets and made that L' ish or U' ish turn and picked up speed! ??? (shaking my head) lol Hubble Telescope still up there, and has taken pictures of of other Galaxies, Nebulas, Clusters of stars , and all we get from 'Oumuamua' are just like Cartoon Animations? Also the S.E.T.I. (Search for Extra Terrestrial Intelligent life) Telescopes, and we get no radar or any type of images.

[@Graeme_Lastname]

Perhaps it's just a transport ship making a mid course correction to avoid crashing into the dark side of the sun. ;)

[@baikonur58]

Это ж имперский крейсер, посеченный метеоритами!

[@agrillhasnoname]

Dear youtube scientists, when this object was at his closest position to Earth, don't we have any satellites that can photograph or film it? What is the closest distance it would have to be for us to get a real image of it?

[@JeffersonHunter]

Check out the paper (page 3) to see an image. You will be disappointed ;)

[@agrillhasnoname]

+Matthias Jaeger what paper?

[@JeffersonHunter]

The one in which the new results presented here are discussed: www.eso.org/public/archives/releases/sciencepapers/eso1820/eso1820a.pdf

[@agrillhasnoname]

+Matthias Jaeger I see images of dots. Yes, I'm disappointed in mankind for wasting so much money on wars and not on space exploration instead.

[@ishiable]

Yesss seriously..hubble got just a dot..when it was closest to earct...but hubbke usuallyy takes fuul images of planets and stars and nebulas which are million light years away...they are fucking eith us..they know what is it
