介绍： Who was NASA's first chief of astronomy? Nancy Grace Roman, Edwin Hubble, Carl Sagan or Annie Jump Cannon? NASA's first chief astronomer who is known as the mother of the Hubble telescope was Nancy Grace Roman.
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.
NASA says this will help it observe more of the sky in less time and that's intended to help it hunt down rogue 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 meander through the galaxy on their own.

There are a lot of ideas about how these planets form and why they go rogue.

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。
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。
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。
