In 2017, astronomers discovered 'Oumuamua - the first definitive interstellar visitor to our solar system. But definitive evidence of space rocks that don't just visit but join our solar system is a little more elusive.

I remember Hyakutake. I was 8 years old, and my parents drove us a couple of hours out of Denver into the mountains to see it. I remember it was basically just a very dim, fuzzy dot you could only really see if you didn't look directly at it.
But learning now that Hyakutake might have been an interstellar object makes that memory that much more profound.
Congratulations on getting a chair and a set to film on, instead of just a green screen. Feels like a real step up for SciShow. 🙂
Don't you mean step down? 😂
Scishow are sickos who support torturing animals in mad Science experiments giving them disease and toxic chemicals. Alternative : people dying of disease. STOP CURING DISEASE.
Congrats on 10 years Reid!! :D
I did not realize that the Voyager probes have not gone through the Oort cloud. Wow. That gives me a reason to hope they live another 30 years.
You're gonna have a wee bit longer of a wait. The Oort cloud is way out there and extends halfway to the Centuri system. Space is inconveniently big, well, save when something energetically interesting happens, when it's extra-conveniently big enough to not do that killing us off thing.
Sorry to tell you but its 300 years untill Voyager reaches the oort cloud
Dates vary by source / paper, but their batteries aren't expected to last more than a year or two at this point.
@@spvillano Which is super cool to think about, because the Centuri System's Oort Cloud equivalent could be interacting with ours.
@@SlavaPunta Yes but let's not forget NASA probes have the tendency to live forever, haha. I definitely hope they keep them alive for the next 30 years. 🤞
Also the thought of a piece of our solar system one day teaching aliens about our home kinda warms my heart and makes me feel a little less small in our very, very large universe.
I hope that aliens are one day decoding the gold disk on the voyager.
spatial archaeology
You know I think it depends because if it's a fossil bearing rock i'm gonna be extremely concerned
"Well kids I'm from Earth, my people are a bunch of idiots but I mostly love them"
@@MsHarpsychord Pretty much. I love our anxiety ridden apes of this planet
ʻOumuamua visited our system in hopes of snagging Reid’s chill aloha shirt.
i wish it was buttoned!
@@casjean8904 everyone's entitled to their kink...
I'll just get my hat...
@@spvillano lol
I'm happy that Comet Hyakutake is considered a possible visitor to our Solar system as this was the first comet I recall seeing that looked like a "proper" comet. I recall watching Hyakutake visibly move against the background stars in '96, a warmup for Hale-Bopp.
Hear, hear! Hyakutake was the one of the first comets I was tasked with charting nightly (by hand with pencil, on blown-up star charts) and yes, it was the perfect prelude to the wonder that was Hale-Bopp👍🤌
🖖
Wife: Honey i saw an asteroid going the wrong direction. Ka'epaoka'āwela: its not just one, its all of them.
Reid has a chair now, and a room with retro decor. Hank, eat your heart out. Reid has style and panache!
It's the same set from that video with that stranger.
Omg, he's dressed like a drug kingpin or something, lmao. He's the big man now!😂
@@MySmileStillStaysOna drug kingpin? lol yea if drug kingpins buy their button ups at Walmart
I like the new set. It feels more like a discussion than a lecture.
The only thing better than getting a shot of science from Reid is a double shot. Keep up the great work!
I really like that set. You guys just get better and better!
Having veen lucky enough to co-author a paper on 2I/Borisov, I'm always happy to see it represented :D
But also: I haven't had time to keep up with papers on it since, but it's really nice to see that entirely different avenues of study (we used a... rather obscure one) come to the same conclusion! Because we also said that the comet likely never went close to its parent star before escaping its solar system
What do you do as a job? I’m interested
So, it had mommy/daddy issues and decided to move out of the country? lol
@@ilpi7216 usually, the mommy/daddy issues result in it getting kicked out of the house.
@RokNezic yep, replication is cool - especially when other methods confirm initial results! Science at its best!
Of course, Retraction Watch is also science at its best, as it's exposing science at its worst.
Obligatory Garden of Rama joke inserted here...
I'll disagree with our host on "we'll never know" on ISO candidates, a drill and sample return mission could easily yield samples that could give an isotopic mixture that's decidedly non-Sol system in nature. Or not. Either way, we'd learn something, just as we did from I1 and solar radiation effects and outgassing. Well, that or the Ramans always do things in 3's.
You knew that joke was coming, yes?
This format makes it feel like we're on a date with Reid and just asked what his hobbies are 😅
Not that im complaining 😘
LMAOO WAIT THATS SO ACCURATE
Dear SciShow,
Please do an episode about chronic kidney disease! My dad has been diagnosed and is like to get the run down the SciShow way! All these other videos aren’t getting me the info I need! Thanks!
A concerned daughter
I'm diggin' the Casual Reid-ing Corner vibe, gives his shirts a chance to play their role in viewership 😄
The absolute drip on this man
I love the casual nature of the set... It's oddly refreshing!
I just discovered your channel a few days ago. Congratulations on 10 year's. I'm already enjoying binging! 🤘😎🖖🇨🇦🕊️
A real Christopher Columbus over here.
Congrats to Reid on 10 years of hosting SciShow videos.
The vibe of this video makes me feel like I'm in the room with homie chillin talking about "space stuff"
Also GREAT SHIRT...reminds me of the dude from CURIOUS DROID. That dude has some FIRE shirts lemme tell you.
Regarding Comet Bowell, I'm now sitting here imagining a civilization on a far away planet having some kind of educational briefing on this weird flaming ball of ice that came from outside their system and wondering how it happened
I really love the style change for the presentation. I feel like I'm retaining more information from this more conversational experience! Thanks so much for the always-awesome science videos!!
I have some delay on watching Scishow and I am just discovering the new studio, nice and cozy 😊
The rarest objects in the universe is the person reading this. There's only one of you. Take care of yourselves.
awhh🥹🩵
Right in the feels
And yet I'm oh so replaceable
You made my day. Thank you!
Well played!
5:42 I Saw comet Hiakutake back in 1996. The most overwhelming spectacle of nature I have ever witnessed. It was more than 60⁰ in the night sky, I had to move my head to fully contemplate it.
thanks for doing all the hard work and creating the metric. can't wait to start testing it out myself this coming weekend.
Wonderful host for this video, I hope we shall see more of him in the future.
Really like this new setup!
that is a really cool set! the topics covered are always interesting, but it is also cool to see that the set is getting more interesting too :3
I like the "new" set your using. At least I've never seen it before, so its great looking. Keep using it.
Loving that new studio.
This guys one of my favorite narrators on your channel besides , of course Hank
Great content ❤
Omuamua is further then Uranus 🤣
Speaking of ʻOumuamua, I recently started my 3rd listening of Rendezvous With Rama. Just noticed this from chapter one:
*At 09.46 GMT on the morning of 11 September, in the exceptionally beautiful summer of the year 2077, most of the inhabitants of Europe saw a dazzling fireball appear in the eastern sky. Within seconds it was brighter than the sun, and as it moved across the heavens-at first in utter silence-it left behind it a churning column of dust and smoke.*
what's that in the sky? is it a bird? is it a plane? is it an alien spacecraft?
nah, it's a rock (or something) saying hi :)
I was just watching NileRed before seeing this and "nah" made me think of baking soda (if you remove the end of the formula because that is made of CO3).
"look! up in the sky!"
"it's a bird."
"it's a plane."
"it's ..., it's ...-"
SPLAAANNNG!
"... a piano ..."
It's a...turd? O.@
@@masterChiZhee *splat*
eeeeewwww ...
Long time no see, where were you mate?
Moon
Remember we have only closely watching for, and plotting the orbits of, all objects for the last few years. This due to concerns over possible Earth impactor objects.
This implies that small interstellar objects are more common then we thought.
I knew space was vast, but I didn’t really grasp it until you mentioned the time it’ll take voyager to reach the Oort Cloud. I thought these things were so much closer than this… that is insane. 🤯
I like the new set, and now you get to take a seat! 😀
Oumuamua always gave me extreme Rama vibes.
I have that shirt too!!!
You know what the actual rarest object in the Solar System is, It's you. There is only one of you in the entirety of everything. That is one hell of a fantastic thing.
@@bywonline so profound
@@bywonlinewrong, oumuamua is a space hot dog
Yep he's unique just like everyone else
@@keb7066the forbidden space hotdog. 😂
I swear I saw this video the other day?
yeah, me too, skimming through this video i recognize all of the names mentioned and i know for a fact i saw them all in a recent scishow video
I noticed that the original video they posted is deleted now. I wonder why they reuploaded this one…
Had to hear the where's Waldo comment twice
Perhaps there were some things they really felt needed to be fixed?
I swear i saw this comment on the same previous upload which they deleted.
Thanks for the vid, super interesting
The chair is a bit distracting, particularly with the high arm/head rest. maybe something a bit like John's early crash course chair and desk, not the leather fire place chair.
We need to have an intercepting vehicle ready in space to catch up to the next Oumuamua that’ll cross our path.
It was supposed to hit, but the three body problem plagues extraterrestrials too.
That chair looks like it was custom made for Reid 😎
Great episode, as usual. the new host sitting down format looks more uncomfortable than when they used to stand though.
What ISO do you think I'd need to use to photograph an ISO? My camera only goes up to 6400.
when i hear of objects coming into the solar system my mind goes crazy with thoughts of where its been and how long its been going for and if it even came from outside the milky-way. has it been traveling for billions of years in IGS or from another Galaxy altogether? probably not but i still like to imagine its journey and the different planets/sun its past and has someone on those planets thinking the same thing as me as it past by them ? again probably not lol.
From the thumbnail I can promise you I saw one of those at about 8:30 this morning
did this video get removed and had to be reuploaded or something?
Yep
I thought they just remastered it
The audio was fuggy
you sound like Penn of Penn and Tellar. I just can't escape it
Omg you are right! A lot less bombastic and more gentle, though : )
The voice of this man is amazing
Thinking about things like this makes me sad that my life is too short to witness certain astrological breakthroughs.
Love the new casual setting. The standing chats was getting old.
Woah that's cool...so is our solar system a run of the mill system or is it really weird?
Sitting down this looks way comfier, i love it.
That back part of the chair looks like the weirdest shoulder pad
Are interstellar objects rare or are we able to see more of them now using technology to search space
I was expecting a Despicable Me quote at the beginning of that ad read. Vector, a quantity with both direction & magnitude.
Remember to water that plant Reid !!
It seems that the odds of an interstellar object entering our solar system is so low you’d expect it to nearly never happen. It might be like shooting a bullet from Mt. Rainier with a really powerful gun, but hitting a target on Maui. It might even be harder than that. But gaps between solar systems are so vast that odds are, an interstellar object would simply fly through space for eons without hitting any solar system.
Incase you're wondering, 400 billion hours is = 45,631,783 years
Sci Show Space is now broadcasting from Reid's basement.
I randomly found this object on the NASA app. The eyes on asteroid function is like Google maps for the solar system. From 1949-2049
Thus some of the descriptions of the object were as hyperbolic as the path of the object.
Space may only be an hour's drive away, but the depths of the ocean are even less that--only about 7 miles at its deepest. Of course, it's not the actual distance that's the problem!
It's interesting to think that all sorts of things may be going on in the universe, but it's so large that only a fraction of a fraction of it is happening right here in our solar system. When we manage interstellar travel, we'll probably discover a lot more interesting stuff.
"Sweet! Were in space! That was quick! How much longer till we get to the moon?"
*1 0 0 D A Y S*
I so wish we could come across another planet's Voyager.
"Omouamoua is already further from the sun than Uranus is"
Wow, they finally got you a chair. Just in time for a cool video.
What I’m hearing is that outside our solar system, its really cold.
There must be only one artistic rendering of Oamuamua. I only ever see that one.
So 1I is not on its way back to our solar system like many of the other You Tube channels say. Actually some people will be sad that 1I is not coming back to our Solar system.
That's a joint
Maybe some day they'll manage to catch an interstellar object.
Gosh can you imagine if we could have been able to tag it with a dash cam to collect data to be sent back to earth best part is we would only need the power to run the tag as the asteroid is doing all the work of travailing for us.
What about that moon of Uranus or Neptune that revolves the opposite direction to all the other moons?
On a Celestial scale, I think Earth is pretty rare in the solar system
Since our sun is a main sequence star fusing hydrogen into helium, doesn’t that mean virtually everything around us came in on an ISO at some point?
Comet Bowell and Uranus. There's a joke in there.
He is working so hard on the pronunciation.
I believe that an object in a solar system can only go hyperbolic if:
A. It has its own propulsion, or
B. It’s interstellar.
I’m no physicist but I believe a hyperbolic trajectory only happens if an object’s speed is high enough to achieve escape velocity. In this case I guess the Sun would be the candidate for that object to revolve around but a hyperbolic orbit comes in flat and leaves flat, usually gone to the next solar system, wherever that might be.
Gravitational assists are also a thing. If an object passes too close to a much larger object (like a planet) its velocity (speed and direction) is going to be significantly altered. Plenty of space probes have exploited that to reduce the fuel requirement, but the larger planets could just as easily boost a random comet onto an escape trajectory.
Did we track it to where it could have been coming from? I mean if you know the trajectory, hyperbolic or and other form, can't we trace it back?
It's not that simple. Even if it came directly from one of the closest stars (which it didn't), that's still thousands of years ago. Stars are constantly moving and affecting each other's orbits, and these rocks have probably been travelling through interstellar space for millions of years. It's not really possible to extrapolate backwards on those sorts of timescales.
Hi Reid!
This feels familiar.
I SWEAR THIS VIDEO SAW ME THE OTHER DAY
Nice medicine pouch.
6:24 - We, as in humanity as a whole might well figure out someday whether those objects really are of interstellar origin or not. I'm certain that knowing more about the solar system as a whole and those objects in particular would enable us to firmly place them in one category or the other.
Some things we'll never know for sure because the evidence is too mixed up to ever feasibly untangle it. But I don't think the origin of these objects is like that.
Cosmic rays, Extra Solar Particles do irritate my skin.
I swear the rarest object in the solar system is the actual Sun 😂
"We will make a wall and make the Proxima Centauri-ans pay for it"
im so high rn that i thought the thing in the thumbnail was a blunt, great video tho.
Halicona plant, flamingo shirt, Maui hook… brah you on island?
Someone knew what they were doing with this thumbnail
How do they distinguish an ISO from something that originated in the Oort cloud?
They are traveling faster than the solar system's escape velocity. Which leaves only 2 options. Something very massive like a planet gave them a gravitational assist, like we did to get the Voyager probes on a trajectory out of the solar system (I'm assuming scientists ruled this out based on their position relative to the positions of the planets), or they must have come from outside the solar system.
@@phaedrus000 Thank you! Of course, this assumes there is not a planet sized object in the Oort cloud that could accelerate objects, no?
@@bomafett I think so, but I'm definitely not enough of an expert to say. But that does make sense. If Planet X is out there, then I suppose maybe these could be from our Oort Cloud.
2:51 💀
So what you're telling me is that we need an interstellar ICE to spot interstellar ice?
I'll let the space forces know.
So it was a skipping stone.
