And then you launch it. and first you have to deploy the sun shield so that you are protecting the telescope from the sun. which is huge. the sun shield will stretch out to be as big as a tennis court. and it will just then slowly sail away from us a million miles away and then slowly deploy these hexagonal shapes. this is the largest ever space telescope we've ever launched. >> amazing. >> yeah. >> and we are about two minutes away. and if we do get countdown, i'll have to interrupt you. but i want to look at that it will study things like super massive black holes, dark matter of space, but ...

Enter the rocket, so it has to deploy, and this will take 29 days to be done really perfectly, like a surgical operation. think about it, just like the sun shield, done by 100 little pieces of operation that have to be done to the millimetre, perfect. in order to make it a great telescope. the mirrors have to align, the instrument has to cool down, they have to arrive to —34 kelvin in order to work perfectly in the infrared. this will take a few months, probably in operation in three of four months. so months, probably in operation in three of four months.— months, probably in operation in...

From the most distant stars. it also has a huge sun shield, about the size of a tennis court. it's made up of five layers, each as thin as a human hair, and this protects the telescope from the heat and light of the sun. sitting a million miles away from the earth, the telescope will give us our deepest ever view of the cosmos. from seeing the birth of the very first stars and galaxies, to revealing new planets in far—flung solar systems. what excites me is making discoveries, things we haven't thought about. and there's a whole history of astronomy that shows how, when we've looked at the n...

But 100 times more powerful. after three decades in the making, and a cost of $10 billion, it's finally on its way. we've never attempted anything like that in space before. we're going to be entering a whole new regime of astrophysics. a new frontier. and that is what gets so many of us excited about james webb space telescope. this space telescope is a feat of engineering. at its heart is a 6.5 metre—wide mirror, made up of 18 hexagonal segments, each coated in a layer of gold. its size means it can detect the incredibly faint light coming from the most distant stars. it also has a huge su...
