안녕하세요, 브레어 토끼입니다. 오늘은 NASA에서 어떤 우주의 모습을 비춰줄까요?
먼저 사진부터 감상하시죠!
이 사진의 제목은 All of These Space Images are Fake Except One 입니다. NASA에서 공식적으로 제공한 사진 설명을 보시죠.
Why would you want to fake a universe? For one reason -- to better understand our real universe. Many astronomical projects seeking to learn properties of our universe now start with a robotic telescope taking sequential images of the night sky. Next, sophisticated computer algorithms crunch these digital images to find stars and galaxies and measure their properties. To calibrate these algorithms, it is useful to test them on fake images from a fake universe to see if the algorithms can correctly deduce purposely imprinted properties. The featured mosaic of fake images was created to specifically mimic the images that have appeared on NASA's Astronomy Picture of the Day (APOD). Only one image of the 225 images is real -- can you find it? The accomplished deceptors have made available individual fake APOD images that can be displayed by accessing their ThisIsNotAnAPOD webpage or Twitter feed. More useful for calibrating and understanding our distant universe, however, are fake galaxies -- a sampling of which can be seen at their ThisIsNotAGalaxy webpage.

광활한 우주 사진을 보면 우리가 살고 있는 지구가 더욱 소중하게 느껴집니다. 오늘도 광활한 우주 앞에 인간이 얼마나 작은 존재인지 깨닫게 되네요.
저는 다음에 더 좋은 사진과 함께 돌아오겠습니다!
