the new james webb telescope has completed a crucial task in its quest to observe some of the most distant objects in the universe. its controllers completed the deployment of the space observatory s giant kite shaped sun shield, which is the size of a tennis court. the barrier will allow the telescope to detect signals deep in space, including from objects present during the formation of the first galaxies. the men s tennis world number one, novak djokovic, will defend his australian open title in a fortnight, after receiving a medical exemption to take part without having a covid vaccine. the serbian s involvement had been in doubt because of australia s strict virus protocols. djokovic, who has previously voiced scepticism about vaccines, hasn t revealed why he was given an exemption. here s our sports correspondent katie gornall. novak djokovic isn t about to give up on this trophyjust yet. the world number one will now defend his australian open title following months of uncertain

provide new insights into the existence of life on other planets. it will help us understand possibilities and maybe even the probability of potential life forms, although we re not looking for a life form itself, we re looking for the environment that would allow life to thrive. reporter: to reach this point has taken $10 billion and combined brain power of thousands, from 14 countries. but it s still just at the beginning. over the next few weeks, webb will continue deploying its antennas, sun shield, and mirrors. each procedure a critical and complicated step to fully assemble the telescope, a process space fans will be able to follow in real time. now taking its first steps in pursuit of cosmology cal discovery. reporter: much larger and a hundred times more powerful than the hubble telescope which launched in 1990, webb can
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. from seeing the birth of the very first stars and galaxies, to revealing new planets in far flung solar systems.
to deploy antennas, mirrors and sun shield. it is 100 times more powerful than the hubble teescope before it. scientists will get a deeper look into the universe capturing light so far that the lens will show images of what happened 13 billion years into the past, maybe even from the beginning of the universe. we are going to discover incredible things that we never imagined. reporter: the new seven-ton telescope will also expand the search for earth-like planets with elements that make life possible. thousands of people from 14 countries worked on the project for more than two decades, and it will be another six months before it is fully operational. celebrations after a successful launch. we have delivered a christmas gift today to humanity. reporter: a gift of knowledge, perhaps unwrapping
