How Can Stars Quake Without Tectonic Plates? (And Other Seismic Mysteries) | Compilation
Astronomers have seen quakes or volcanos on many celestial bodies that don't have tectonic plates like Earth does. So let's take a look around the solar system and see how various seismic features happen.

I'm shaken to the core.
What did the first tectonic plate say to the other tectonic plate? "That last earthquake was not my fault."
I realize this problem may be inherent in any compilation where the segments are arranged thematically instead of chronologically. Still, I found it confusing when, around 8:50, Hank told me about the Insight Lander's seismometer, and 5 minutes later, at 13:50, Reid told me that the Viking Landers had the only seismometers on Mars. I think the latter segment was included for its information on moonquakes and the editor overlooked that it had information on Marsquakes that the earlier segment made outdated. I don't think Hank's intro warned us about that or tried to explain it. The result is not optimal.

Were any engineers involved in setting this compilation up? If not, could explain the lack of optimization? 🤔
I enjoyed this video a lot. Gave many answers to my thinking brain. Thanks sci show space
Ty love the the fun DFTBA!
Quaking rocky bodies is a a great band name
This was a great episode. It talked about stuff I have always wondered about, and some things I never considered. I happen to be very fond of neutron stars and that segment had me cheering for the anomalies in them that continue to make them mysterious. Some day we will build a spacecraft that can withstand Venus' hellish atmosphere and solve the questions it continues to present us with. Space is awesome, scary and fascinating so please keep posting on this channel to keep my brain rotating with new ideas.
maybe a quake like this caused the mystery energy blast this week
"but it's a start!" Actually made me lol
...and in a hundred thousand years the alien will say, "I am not on Earth, nor in orbit". when finally, the sat signal arrives.
Flagging this video as needing (not just auto-generated) subtitles. Please help us hard of hearing and deaf folks access your content!! 🥰🤟🏻
Trip adviser say this is the best place to be in the whole vers.
21:27 The Stars may have faults, but Pizza does not.
Has there been any physics simulations that can calculate how long an impact may cause plate tectonics to shift? Thea collided with primordial earth and that will definitely shake up the crust formation of ANY planet.
12:26 sorry was eating, and i thought 'Mooncakes' and 'Mars cakes' heh...
Aren’t the plates still under your feet if you’re in orbit?🤔…just WAY under.

Depends on your orientation, I guess.
"...must be jelly, cause jam don't shake like that!"
You guys mentioned not having a lot of Mars quake data. The Mars InSight mission has returned a lot of data regarding quakes on Mars over the past four years.
19:30 I know what he means, but he said it wrong. The rotational axis always goes through the center of mass, if there isn't any outside force. What he means is they spin faster if the mass distribution gets denser.
Also could you put a little more into making sure that Comp info isn't confusing or contradicting earlier info. There was confusing stuff on viking
Spank the Hank~
I never actually thought about gravity waves in that light. If a stars mass is unchanged and the collapse or supernova is crushing and expelling the matter that was already present, why is it creating gravitational ripples? Just a question to no one in particular.

Concentration and proximity, gravity decreases with distance, so the density of that matter and where it is matters for how the matter effects the space around it.

0:16: 🌍 Plate tectonics play a crucial role in a planet's climate, weather, and geology, and are important for the long-term survival of life. 4:45: 🌍 The search for extraterrestrial moving plates could help point us in the right direction in finding life outside of Earth. 9:44: 🌍 Scientists have discovered surprising insights about the interior of Mars, including the thickness and density of its crust, the depth and convective properties of its mantle, and the composition of its core. 14:20: 🌋 Evidence of movement and seismic activity on Mars suggests the occurrence of recent MarsQuake on Elysium Mons volcano. 19:13: 🌟 Studying starquakes can provide insights into the internal workings of celestial objects, but many mysteries remain. 23:31: 🌋 Io and Venus have volcanic activity and mysterious features that scientists are still trying to understand. 28:19: 🪐 The surface of Venus is unique with slow erosion, extensive volcanic features, and a relatively young age.

As a child I always thought If I got a genie lamp I would wish for a planet the same size as earth and habitable to pop into existence opposite the sun to earth. And one orbiting 90°to us. So going over and under the sun. That way wr could have 4 earths.
Don’t they mean the gravitational influences from the *Sun* cause seismic activity on the moon? Since the moon is tidal locked and it’s orbit is near circular, Shouldn’t the the gravitational force stay pretty much the same?

The moon's orbit isn't perfectly circular, so any deviation from a circular path will cause some tidal effect. I'm with you though in saying that it's not just the Earth, it's gotta be both the Earth and the Sun. I would even venture a guess that the Sun has the larger overall effect considering the fact that, as the Moon orbits the Earth, it gets continually closer to and further away from the Sun by hundreds of thousands of kilometers each orbit.
Does Uranus have any eruptions
It’s all fun and games until millions die in a plasmaquake.
Um, how much sulfur is on earth, that seems like a really important question now

Hank talks with his hands.
Is Hank CGI in segment 4? Or is the lighting just weird?
I’m watching this video upside down, now what?
Well technically tectonic plates are still shifting below your feet even if you are watching this in orbit. Unless you're orbiting Mars I guess.

Depends on your perspective of down at that point i reckon lol. But yeh you aint wrong
I thought this was about Stars 🤔
I mean im just spitballing here but i reckon that the cause of venus' "new surface" or whatever was prolly caused by the fact thats its a hot ass hellscape. No idea whatd have cause the whole ass planet to get so many greenhouse gasses outta nowhere but if you take a planet thats cool and heat it up like to say... the 900 degrees or whatever venus is, considering that venus is similar in size to our planet as well the deeper you go the hotter it gets. Heat up the surface to a temp that can damn near melt lead then the interior is bound to heat as well which, at least in my head, melts more rock making the crust thinner which in turn would allow for random ass vocanos to pop up all over the place which would only drive the heating more with pumping sulfer and all that other wonderful stuff into the atmosphere.
After using up their planets the Venus and Mars people fought a raging nuclear war against each other over Earth
I don't think I can put any of that in a terrarium,
Hank is aging! His voice is deeper now than it was a couple years ago.
1:36 So the earth has its own methods of regulating carbon? If this is true, then it directly contradicts the plethora of content on your channel regarding the earth's climate.

stable, in this particular context, means suitable for life, not necessarily for most of the specific living things that exist right now. earth's climate can change, but it won't become a burning hellscape (like venus) or something like that.
Wait, there are chemical processes on the Earth’s surface that cool the Earth’s temperature? Nobody thought that deserved further examination?

My thought is that the inner core of a neutron star is a blobby quark star spinning slightly off kilter, because gravity. I could be wrong.

How do they know the planet like didn't have tectonic plates in the past. When it was more geologicly active. Maybe weigh of the oceans are a factor. Maybe even life it self

Plate tectonics involve lighter continental plates made of granite overriding heavier oceanic basalt plates. Granite can only be formed through plate tectonics involving water. If there is no granite, you know there were no plate tectonics as there are no plates.
