By 2030, the world's largest radio telescope will be operational in remote Western Australia, but by then tens of thousands of satellites will be blanketing Earth's orbit with radio noise.
So, this is a key period in the evolution of our universe that we know had to happen but we ve never yet observed it. the other very big science programme that we re hoping to do is to look at pulsars. so pulsars are very precise clocks in the universe. audio cuts out the stars that rotate very rapidly at a very - constant rate and we can look at the changes in the ticking of these clocks to be able to look for gravitational waves as they travel through the universe and distort space time, and this is something that ska mid and ska low high will be able to do very precisely. professor cathryn trott. three chinese astronauts have returned to earth after living for six months on an orbiting space station. their shenzhou 14 spaceship landed as planned in inner mongolia. the astronauts completed the assembly of the space station before handing it over to another crew. all three are said to be in good health.
Of the major outstanding questions in astrophysics. this is an artist s impression of what the telescope will look like, once it s completed in six years. professor cathryn trott is the chief operations scientist on this project in australia. she says the telescope will allow astronomers to study the very earliest moments of our universe. in australia, we re building a low frequency telescope that will operate from 50 to 350 megahertz and in south africa, a telescope operating from 350 megahertz to 15 gigahertz. and across those two telescopes, we re able to look at the full evolution of the universe, from its infancy until the present day. so, in australia here, we re building a telescope that will span nearly 75 kilometres across the western australian outback. it will be nearly ten times as sensitive as any radio telescope that we have now. and what it delivers for us
And in front of mps, a complex bill years in the making, dividing opinion, trying to right that balance between family and big tech. angus crawford, bbc news. ceremonies are getting underway in australia and south africa to mark the start of construction on the world s biggest telescope. the square kilometre array is a network of radio antennae spread across two continents. it will aim to address some of the major outstanding questions in astrophysics. this is an artist s impression of what the telescope will look like, once it s completed in six years. professor cathryn trott is the chief operations scientist on this project in australia. she says the telescope will allow astronomers to study the very earliest moments of our universe. in australia, we re building a low frequency telescope that
And south africa today to mark the start of construction on the world s biggest telescope. the square kilometre array is a network of radio antennae spread across two continents. it will aim to address some of the major outstanding questions in astrophysics. this is an artist s impression of what the telescope will look like once it s completed in 6 years. professor cathryn trott is the chief operations scientist on this project in australia. she says the telescope will allow astronomers to study the very earliest moments of our universe. here in australia the telescope will have a couple of very large science goals to be the first is to look at the cosmic lawn, this is a period 200 million years after the big bang, that s 13.6 billion years bang, that s13.6 billion years in our past when the universe was dark and filled with neutral hydrogen gas. the very first stars and galaxies turn
