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 three of four months. so we will be atient, three of four months. so we will be patient. but three of four months. so we will be patient. but it three of four months. so we will be patient, but it is three of four months. so we will be patient, but it is very three of four months. so we will be patient, but it is very exciting, - patient, but it is very exciting, and ijust wonder, what might
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 new universe in a new way, we discover things we hadn t thought about. and there s something really exciting about doing that. to get into space, the telescope is so big, it s been folded up to fit inside the rocket. the most challenging part is getting it to unfurl. it s been practised here on earth, and that s hard enough.
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 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.
