The Death Of Mars | The Planets | Earth Science

[@HowlingWolf518]

There's a competing theory that Mars _was_ large enough to sustain its magnetic field, but several repeated impacts (or one big one) during the Late Heavy Bombardment stabilized the core and cooled it down. In other words, if one or two rocks had missed, we could have had neighbours.

[@shukrenan_]

[@theshumsshowforfun2.051]

But its a theory so maybe that may be true or not

[@wazzup233]

The reason why it happened it's because Mars is a bit smaller than Earth and it didn't survived from an enormous asteroid bombardment. If Mars is larger than Earth then that planet would have a chance to flourish life there just like our planet.

Mars still has auroras but on the north pole and has an induced magnetic field this field is unique because it forms a comet like tail which spirals into space however this field is not strong but is strong enough to retain most of the martian atmosphere to allow light scattering through its skies and clouds to form around the globe.

Possibly, but but the expansion of the sun will probably make Earth uninhabitable well before this happens (say, Earth turns into another Venus when the sun boils off the oceans; and then gets mostly burnt away when the sun goes red-giant).

The drag of the dust cloud dragged everything in passing through differentiated layers of the spinning dust cloud. There must have been a water region and a nitrogen region of the disk. Ahhh that's why Titan and Europe have volatiles on the surface! The Gas planets also had large differentiated disk around them too!

Something has to sustain it just like what we have on Earth. It could be something as simple as tourism in the end that keeps colonies going.

5:15: 4.6 trillion years ago, Sirius was formed for the Swedish who were dying in the Milky Way. Sirius has always three suns. You see two rocks collide and created the first burning Saturn.

Mars is awesome. We will transform it in the future, watch

thats really sad

[@tygical]

we should really try to get mars's core spinning again before trying anything else for terrarorming

[@sintes88]

So in the end size does matter

[@IngridKen]

The magnetic field is still intact, there's alot of discoveries and evidence 2020-2021, although weak, it still fights for its planet

[@cwuzii]

Are your videos just snippets of documentaries now??

It's just TOO SMALL! :(

Did Brian Cox offend someone? It’s odd that a BBC KZbin channel is using clips from the PBS/Nova redub of this show…

[@ALegendthateatslunchatam]

what if venus and mars swapped places

[@xd-qg5dz]

Venus has no magnetic field today so probably another dead world just slightly larger. If it was rotating faster like earth, then it would probably be full of life.

[@wazzup233]

What about switching mars and earth? Then Ice Age on our planet would be forever. 🥶

[@Matt-jp6if]

Could we genuinely in some distant future “create” a new moon for Mars to liquefy the core once again? Even if it doesn’t matter in our lifetime, it could one day give rise to life on that planet..

[@koharumi1]

If Venus was swapped with Mars...

[@bringbackthetwinntowers2429]

Venus would be in a better and longer time habitable position than Earth

[@adarsh4764]

If you mean by Venus being in Mars' place from the beginning then we would be surely having a 2nd habitable planet in the solar system. But if you mean by swapping the present Venus to Mars orbit, nothing much would change for Venus as its Greenhouse gas would still keep its surface way too hot for life to survive. But there's another thing, Venus doesn't actually have a intrinsic magnetic fieldnlike Earth which is generated by mantke convection current but instead Venus has a substantial magnetic field because of its Ionosphere and thick heavy atmosphere.

[@markloosen3430]

I’m confused about “there was less material out there than where earth was formed”what about Jupiter? It’s a pity though that there is no magnetic field around mars today as this would make staying there in the near future so much easier.

[@coenkloppert]

Jupiter is mostly gas, in the formation of the solar system the most dense materials such as hydrogen and helium were expelled outwards towards the orbit of the gas giants and the heavier elements like silicon were mostly based in a disk close around the sun. All planets formed there,actually, but the gas giants slowly migrated outwards absorbing the gas in the outer solar system into their huge atmospheres.

[@coenkloppert]

Another fun fact to mention is that scientist think Mercury actually formed as the furthest rocky planet. Assumed is that it was slingshotted inwards by Jupiter in the early days. Also explains why Mercury has water ice on its surface because no water would be present at the distance it currently orbits.

[@markloosen3430]

@@coenkloppert Ok, so Jupiter with its 143000 Km diameter has less Mass ( material) then Mars with 6800Km diameter ? Still confused

[@octaviusv]

@@markloosen3430 More like, the stuff that makes up Jupiter is lighter, but the combined total mass of all that light stuff is greater than Mars, which is made up of heavier stuff.

[@coenkloppert]

@@markloosen3430 Jupiter formed as the first planet so it was able to eat all the lighter material and gasses, thats why its so much bigger then even the other gas giants.

And just like that 50% of the planets in entire universe fall out of equation for having life. The other 50% doesn’t leave much wiggle room either...

[@Fido-vm9zi]

Lol 😆

[@achinism]

Life didn't become a thing on Mars 'cause it has too little atmosphere, in retrospect big Jup has too much which is also a big no-no. I've really come to appreciate the responsible middle child, Earth!

[@manojmaitydm]

Same will happen with earth
