starts feb 22nd on d w. plus . if we just take the time to observe it nature provides us with a fascinating spectacle. over time the inhabitants of our planet of woven complex relationships of collaboration symbiosis dependence and predation. earth is the planet of life running crawling all flying life abounds everywhere. but for all these beautiful diversity to have proliferated the earth has had to provide a favorable environment for around 4000000000 years. more

then with the conditions which enables the blooming of life on earth. and could these conditions be present elsewhere resulting in alternative ecosystems. in attempts to answer these questions scientists get all the cosmos for science. life. they've built giant telescopes with which to probe the universe and listen to the whispering of the stars but space has remained resolutely silent. scientists have sent probes to the very edges of our solar system. but all they have sent back has been images of planets inimical to life. over the last 25 years however astronomers have discovered thousands of incredibly diverse planets in our galaxy alone. so many strange worlds with no sign of life not one of the

planets similar to our own so could it be that earth really easy to make. in this program scientists will tell the fascinating story of how earth developed how this bowl of ice and dust became the planet of life. in their liberal trees or out on the ground they continued their research into the extraordinary circumstances which allowed life to appear and eventually transform this planet. they said to call palos all the we're trying to understand but with all the possible outcomes what it was that made the uniqueness of our system was there and

then of course shit seems like earth's climate fix that self to always be favorable to life that's amazing sickish with us who don't know. each will explain the incredible saga from the viewpoint of their own discipline from the birth of our planet to today's ecosystems it's a story punctuated by an incredible succession of lucky accidents to evolve a feeling that it was she. there's the analogy with the lottery the game you know the 3 of the probability of winning is that i need so i think so in the game of planetary formation forming a solar system with our earth is like winning the lottery. scientists are only now 15 together all the various chapters of this turbulent history our history that of a succession of helpful nudges lucky chances and beneficial cataclysms. without a helping hand from jupiter and saturn without the moon without hurtling comments without the power of volcanoes without the genius of certain micro-organisms we

would not be here you perceive that it's possible that life is a one off if we see exactly you know or else that only our last has all the conditions necessary for life as we know it that could occur in the. let there also sausage in that sense earth is probably unique although we may detect some life elsewhere that it will necessarily be completely different. only it was this mind blowing series of improbable events that made earth the possibly unique life bearing planet it now is. the idea that earth main. could have been spawned by these famous photo taken on the apollo 8 mission in 1968. changed our way of looking at.

there is al planet floating like an oasis in the magnificent emptiness of space. for the 1st time there we all were bacteria mammals insects and plants on the same photo our planet a unique ecosystem and even today this photo hints that vein. with clouds an envelop in its the anatomist fear could be alone in the universe. the 1st reason earth was able to become this welcoming blues fear is because it's at just the right distance from the sun in a narrow zone not too hot and not too cold where the temperatures are compatible with liquid water and life. but planetology just have discovered that earth's very presence in this goldilocks zone is itself to an amazing stroke of luck.

when the solar system was still young and this zone came close to being taken over by the planet jupiter so how was earth able to form here. research into the answer to these puzzle has been carried out it needs observatory . sundram or be delhi has written a new account of the birth of our solar system. how many years a lot is it is there but it working on the origin of planetary systems as like being a detective you arrive at the crime scene and use the clothes to try to work out what happens if by sea. knew about the abuses them so that act will issue from our solar system as it is we try to reconstruct how it formed and develop a doc when we come up with a scenario we get

a shiver of excitement with thinking that maybe we've got close to what actually happened for us here in. planetology just start from the present position of the planets attempting to hypothesize a scenario of the solar system's formation with the help of computer simulations. our solar system like all planetary systems formed from a cloud of gas and dust that surrounded the young son 4500000000 years ago. but our solar system seems to have a very different structure from the majority of planetary systems discovered over the last few years. old really cool we now think that our solar system is pretty magical to them so they have a lot of chance events had to happen for it to be as it is usually this suggests that our solar system isn't a typical planetary system but a relatively rare one more. because all shamash when we look at planets around

other stars we see that climates of a similar master jupiter are found in earth's spark plus they left there this is an important if jupiter was in the spotlight earth it wouldn't be here so they put up . the discovery outside our solar system of giant planets similar to jupiter but much closer to their star posed a serious puzzle for astronomers because giant planets of that kind cannot form in such suns you planets are far planets form in a disk of gas and dust that surrounds a young star the giant planets form far out where it's cold where there's ice which lets these planets grow to a huge size clothes. like a snowball rolling down a snowy heal the planet grows ever. or bigger as it gathers to itself all the dust in its path. it calling it late when

a planet gets big enough when it acquires enough mass it migrates and works towards a star athlete was on the. understanding this phenomenon was a real revolution planetary migration explains why the majority of giant planets discovered elsewhere in the galaxy don't stay in their distant orbits as they formed a spiral inwards towards this dark but in that case why didn't our own giant jupiter migrate closer to the sun why did it stop just in time leaving the space free for the future earth. young scepter should go on portables the saturn is very important this is a giant planet too and as we've studied the dynamic between jupiter and saturn we've realized that saturn was able to stop jupiter's migration and even reverse it off it should be so jupiter started migrating to the sun but when saturn appeared there was a complicated gravitational effect which reversed the migration and the planets

moved further from the sun one usually. thanks to saturn the giant planet jupiter changed trajectory it left the in a zone of the solar system and it was this change of course that saved earth's future. without the intervention of saturn jupiter would have ended up in the zone where earth now is earth would never have formed and we would not be here. our planet was luckier than its future neighbor mars because on its migration jupiter passed through design when mars was forming. the giant planets swallowed up a lot of the material available leaving only crumbs for mass our neighbor would end up with 110th the mass of earth which in turn. reduced its possibility of maintaining an atmosphere favorable to live. good i mean

we're understanding how planetary migrations totally changes how the planets get distributed player sized their position in space and the collisions between these objects before they stabilize the planets make the system developed and it's only a particular way with a 53 year. narrowly st by assassin our planet could keep on growing and being just the right distance from the sun meant that it would later have liquid water on its surface. and yet 4500000000 years ago our planet was completely drying it formed in the rockies own in the solar system gathering up dust with barely any water content so where did this water which would later give us our oceans come from. on tour initially in danger and now young earth jupiter would give it

a helping hand. and also a lock but unless you're willing to be there like quasi we think that the formation of the growth and the migration of jupiter outlet these bodies which formed far out in the solar systems and so there was cold bodies with water sent towards the enters around where they crashed into the still forming earth contributing their elements to it but then orders anymore that. these bodies asteroids and comets enrich the chaotic pull of matter which earth then was with water but as our planet started to solidify the water molecules remain trapped under the surface in the magma. yes an essential mechanism for. and its future was already in place and starting to bring some of that water to the surface. it's a mechanism that still very active today. little

. room with. these folk a knows these mountains of fire has been helping to bring water to the surface from the very beginning in earth's youth there was

a lot more full kind of activity than today. so i go home now both when you 1st think about a volcano you think of lava danger and life threatening eruption but volcanoes were essential for life as we know of you and that can occur in the.
