Monday 25 April 2016 Go to http://stedu.stheadline.com to listen to the story Billionaire wants to send spacecraft to nearest star Robot explorer will be as small as a computer chip R USSIAN (俄羅斯的) billionaire Yuri Milner recently announced a plan to send a spacecraft to the star system Alpha Centauri (南門二), about 4.37 light years away from us. That is much farther than Neptune (海王星), the planet farthest from the sun. Scientists thought that this was impossible, because sending a spacecraft would take too much time and energy. Milner and his team has decided instead to make the spacecraft very small – as small as a computer chip! Its speed will be about 20 percent the speed of ▲Yuri Milner (L) and cosmologist Stephen Hawking (C) pose with the prototype ‘Star Chip’ spacecraft.

More to Know ‘Light year’ is a unit that does not measure time, but distance. A light year is the distance light travels in a year, which is equal to about 9,000,000,000,000 kilometres. But when ‘far’ means something we cannot see, the comparative is ‘further’ and ‘furthest’ respectively. - Do you have any further questions? - The novel explores the furthest extremes of human emotions. But ‘furthest’ can also be used when we talk about distance. - That is the furthest I could see without glasses. light year (n phr) 光年 planet (n) 行星 energy (n) 能量 estimated (adj) 估計的 Challenge
