It is one of the oldest questions ever asked: Are we alone or is there other
life out in the
Universe? Last week, an international team of scientists and
businessmen launched a project they
hope can answer that question. They announced plans for a huge space exploration program.
Its goal is to find alien
life in space. The team includes British physicist Stephen Hawking,
Russian-born billionaire Yuri Milner and American Mark Zuckerberg, who founded
Facebook. Their project is called Breakthrough Starshot. It will develop and
build thousands of robotic vehicles that can speed through space. Their
first goal is to explore the nearest star system, Alpha Centauri. It is about 40
trillion kilometers — or 4.37 light years – away from
Earth. Once launched a spacecraft would have to
travel 20 years to get there.

the universe = 우주 (밖) 생명체/ launch = (특히 조직적인 일을[에]) 시작[개시/착수]하다/ space

light year = (천문) 광년(빛이 1년간 나아가는 거리. 9.4607 x 1012 킬로미터)/ spacecraft =

The way they will make it happen is like
something from a science
fiction story. Crews on Earth would use
powerful laser
beams to power extremely small
vehicles
through space.These spacecraft would travel much farther than any other
spacecraft built to
date. Estimates say the project will cost from $5 to 10
billion. Yuri Milner is giving the project $100 million to get started. Last
week, Milner showed a model of the spacecraft to reporters in New York. “This is
a starchip, a gram-scale wafer containing cameras,
photon
thrusters, power supply and
navigation and communication equipment.” The starchip is a computer chip about
the size of a large postage stamp. Each one will cost no more than an iPhone.
The chip will have a light
sail — very thin material that can open in space and move
the spacecraft forward. Together the chip and the sail are called
“nanocraft.”
