A quasar is an object far out in space that looks a bit like a star — a sharp point of light — but is not a star. It shines with huge brightness, far brighter than an ordinary galaxy, even though it is so distant that the light has travelled for billions of years.

A quasar類星體 is是 an object far out in space一個在太空深處的天體 that looks a bit like a star看起來有點像星星──a sharp point of light一個銳利的光點──but is not a star但其實不是星星。It它 shines with huge brightness會發出巨大的亮光, far brighter than an ordinary galaxy比一般的星系亮得多, even though即使 it is so distant它那麼遙遠 that the light has travelled for billions of years使得那道光已經走了幾十億年。

Scientists first found them as strong radio sources that looked almost like stars, and the name comes from that: quasi-stellar, “as if they were stars.” Though actually, we now take a quasar to be the very bright centre of a young galaxy, where a huge black hole is pulling in gas; the gas heats up and pours out light.

Scientists first found them科學家最早發現它們 as strong radio sources是很強的電波源 that looked almost like stars看起來幾乎像星星, and the name comes from that名字就是這樣來的: quasi-stellar意思是類星的, “as if they were stars.”「好像是星星一樣」。Though actually不過其實，we now take a quasar to be現在我們認為quasar是 the very bright centre of a young galaxy一個年輕星系非常明亮的中心, where那裡 a huge black hole is pulling in gas有一個巨大的黑洞正在吸入氣體；the gas heats up and pours out light氣體因此升溫並噴出光。

You will meet the word in science news and astronomy, not at the dinner table. It is a 1960s science word, and it is still the normal term.

You will meet the word你會在 in science news and astronomy科學新聞和天文學裡遇到這個字, not at the dinner table而不是在飯桌上。It它是 a 1960s science word一個1960年代的科學用語, and而且它 it is still the normal term至今仍是通用的說法。
