美国有线新闻 CNN NASA以哈勃之母南希·格雷丝·罗曼命名新望远镜

Who was NASA's first chief of astronomy? Nancy Grace Roman, Edwin Hubble, Carl Sagan or Annie Jump Cannon¹? NASA's first chief astronomer² who is known as the mother of the Hubble telescope was Nancy Grace Roman.

美国国家航空航天局（简称NASA）的第一任首席天文学家是谁？南希·格雷丝·罗曼、埃德温·哈勃、卡尔·萨根还是安妮·詹普·坎农？美国国家航空航天局第一任首席天文学家是被称为“哈勃望远镜之母”的南希·格雷丝·罗曼。

She's also the namesake of NASA's newest telescope. The Nancy Grace Roman Space Telescope is set to launch sometime in the middle of the 2020s. NASA estimates it will cost between $3.2 billion and $3.9 billion. Its viewing area is said to be 100 times larger than the Hubble telescopes.

美国国家航空航天局的最新望远镜将以她的名字命名。南希·格雷丝·罗曼望远镜将于2025年发射。NASA预计，这项工程将耗资32亿美元至39亿美元。据称，该望远镜的观测范围比哈勃望远镜大100倍。

NASA says this will help it observe more of the sky in less time and that's intended to help it hunt down rogue³ planets. Didn't they make a "Star Wars" about this? Scientists say rogue planets are found outside our solar system and they don't orbit stars like Earth does. They meander⁴ through the galaxy⁵ on their own.

NASA表示，这将有助于其在更短时间内观测到更多天空，同时帮助其追踪“流氓行星”。《星球大战》不就与此有关吗？科学家表示，“流氓行星”在太阳系外流浪，不像地球那样围绕恒星运行。而是在银河系中蜿蜒穿行。

There are a lot of ideas about how these planets form and why they go rogue. They're not easy to find since they don't g?ive off light. And they don't give off much heat either which makes them difficult to detect using infrared⁶ light. NASA hopes that the Roman Telescope will help scientists track down more rogue planets. The reason they want to do that is because they hope this will help people understand more about how planetary systems work.

关于这些行星的形成方式以及其变“流氓”的原因有很多种说法。由于“流氓行星”并不发光，所以它们不易被发现。而且它们也不会释放过多热量，所以很难被红外钱探测到。NASA希望南希·格雷丝·罗曼望远镜能帮助科学家追踪到更多“流氓行星”。因为他们希望这能帮助人们对行星系统的工作原理有更多了解。

NASA has a different space telescope set to launch next year. That one's named the James Webb Space Telescope. Its cost is estimated at $10 billion. It will be the biggest instrument of its kind and Webb's mission will be to study distant galaxies⁷.

NASA明年将发射另一台太空望远镜。该望远镜名为詹姆斯·韦伯望远镜。据估计，其耗资将达到100亿美元。这使其成为同类望远镜中规模最大的仪器，韦伯望远镜的任务是观测遥远星系。
