Look up next Sunday to see a truly special cosmic event: A supermoon total lunar eclipse.


Not only will the moon be at its closest point point to Earth in it orbit on Sept. 27, it will also pass completely into Earth's shadow, turning the lunar body into a red-tinted "blood moon" for anyone who has clear, dark skies on the planet's surface.


"All of South America and most of North and Central America will see the entire eclipse, while those west of roughly 120°W will see it in progress at moonrise," NASA said in a statement. "You won’t need special equipment to see it. Just go outside and look up!"


This will mark the first time a total lunar eclipse during a supermoon has occurred since 1982, and it won't happen again until 2033.


During a supermoon, the moon can actually look up to 14% larger in diameter; however, everyday skywatchers might not be able to tell the difference.


Scientists can also collect a fair bit of data about the moon during a lunar eclipse that they wouldn't be able to get otherwise.


For example, NASA's Lunar Reconnaissance Orbiter (LRO) will be able to take measurements of the moon's surface temperature.


By learning more about how the temperature of the surface of the moon changes, scientists can actually have new insights about the structure of the surface of the moon, NASA LRO deputy project scientist Noah Petro, said in a NASA video interview.

“通过研究月球表面温度的变化,科学家们可以对月球表面结构有更新的认识”,LRO的助理项目科学家Noah Petro在一次视频采访中说。
