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? 😂
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
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. 🤞
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👍🤌
🖖
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
Congrats on 10 years Reid!! :D
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.
Wife: Honey i saw an asteroid going the wrong direction. Ka'epaoka'āwela: its not just one, its all of them.
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?
The only thing better than getting a shot of science from Reid is a double shot. Keep up the great work!
Omuamua is further then Uranus 🤣
I really like that set. You guys just get better and better!
I'm diggin' the Casual Reid-ing Corner vibe, gives his shirts a chance to play their role in viewership 😄
I just discovered your channel a few days ago. Congratulations on 10 year's. I'm already enjoying binging! 🤘😎🖖🇨🇦🕊️
I love the casual nature of the set... It's oddly refreshing!
Congrats to Reid on 10 years of hosting SciShow videos.
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
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.
Sitting down this looks way comfier, i love it.
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
The absolute drip on this man
The voice of this man is amazing
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
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.
You sound like Will Sasso doing an impression of Jesse Ventura and I absolutely love it
I have some delay on watching Scishow and I am just discovering the new studio, nice and cozy 😊
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!!
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.*
thanks for doing all the hard work and creating the metric. can't wait to start testing it out myself this coming weekend.
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 ...
This guys one of my favorite narrators on your channel besides , of course Hank
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!
Wonderful host for this video, I hope we shall see more of him in the future.
Someone's lobbing skimming stones at us!
I like the "new" set your using. At least I've never seen it before, so its great looking. Keep using it.
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
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.
Fans of sci-fi were disappointed that the object was named "Oumuamua" instead of "Rama."
Rama's not due for a few decades yet.
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. 😂
Loving that new studio.
Great content ❤
Best explanation for "Ouamuaua" since it did not have a visible inbound track was there was none. It was ejected from the star, which is also why there was no tail. Stars do eject material, you can see it in most videos.
From the thumbnail I can promise you I saw one of those at about 8:30 this morning
We need to have an intercepting vehicle ready in space to catch up to the next Oumuamua that’ll cross our path.
That chair looks like it was custom made for Reid 😎
@9:00... Vectors are much more than "just descriptions of movement through space."
I have that shirt too!!!
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. 🤯
It was supposed to hit, but the three body problem plagues extraterrestrials too.
1:55 zentraedi flagship. Launch the Valkyries.
Thinking about things like this makes me sad that my life is too short to witness certain astrological breakthroughs.
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.
I found six for sale in the Barras in Glasgow, I bought 4. Thought better not buy them all, let someone else get one.
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.
"Sweet! Were in space! That was quick! How much longer till we get to the moon?"
*1 0 0 D A Y S*
Great episode, as usual. the new host sitting down format looks more uncomfortable than when they used to stand though.
I like the new set, and now you get to take a seat! 😀
8:52 Or as they should officially call it, "the red flag delivered to us (the aliens) from that star near-ish to Alpha Centauri." lol
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.
multiverse aliens are watching us, in the intergalactic universes there are aliens that watch us.
I was expecting a Despicable Me quote at the beginning of that ad read. Vector, a quantity with both direction & magnitude.
Incase you're wondering, 400 billion hours is = 45,631,783 years
"Omouamoua is already further from the sun than Uranus is"
Long time no see, where were you mate?
Moon
Sci Show Space is now broadcasting from Reid's basement.
0:41 - If you don't come to Brazil, Brazil comes to you.
Ive seen that thing in the thumbnail before, and let me tell you, it was a mission but it did eventually crash land .
I so wish we could come across another planet's Voyager.
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 : )
9:00 No!! A vector is an element of a vector-space!!! If that vector-space is the cartesian space with its conventional scalar product, then those vectors describe directions in space, but a vector, mathematically speaking, can be WAY more than mere pairs or triplets of numbers.
Tenured Harvard astronomer *Avi Loeb* has been arguing that Oumuamua is an alien space probe due to factors that don't explain it's apparent acceleration out of our solar system.
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.
OOO-ERRRR, that looks like the Domesday Machine from Star Trek TOS.
2:53 - Further from the Sun than my what now?
That back part of the chair looks like the weirdest shoulder pad
Rarity is a matter of definition. To most, it is just a rock.
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
Remember to water that plant Reid !!
Am I the only one who prefers the green screen setup rather than the chair and stuff? It feels more like a cheap talk show now. You know, like "advice for the broken hearted after midnight" kind of thing..
This guy reminds me of The Big Show.
The sun is rarer, there is only 1 in our solar system 💀
Thumbnail look like a space blunt. Some galactic backwoods
Those damn kajiit.
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?
The most rarest object in the Universe is Earth with these strange animals who travel in cars, planes and boats.
I see one or two per day depending on my digestive track
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.
Woah that's cool...so is our solar system a run of the mill system or is it really weird?
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.
The ETs fired a turd across our bow
I've got my eye on Phoebe...
Comet Bowell and Uranus. There's a joke in there.
If a spaceship was out there moving at ludacris speed eventually it would collide with some space junk or some debris….
Thus some of the descriptions of the object were as hyperbolic as the path of the object.
On a Celestial scale, I think Earth is pretty rare in the solar system
did this video get removed and had to be reuploaded or something?
Yep
I thought they just remastered it
The audio was fuggy
Wow, they finally got you a chair. Just in time for a cool video.
Who knew tyson fury was so smart😂
