2021년 12월 24일자 도착할 우주여행 장소는 사진에 나온 장소입니다. 여기는 M1: The Crab Nebula 입니다. The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers in the year 1054. This sharp, ground-based telescopic view com..

If your night sky is dark and horizon clear enough, the Solar System may have done your shopping for you. Send them outside after sunset to see three planets and a comet.

2021년 12월 22일자 도착할 우주여행 장소는 사진에 나온 장소입니다. 여기는 Launch of the IXPE Observatory 입니다. Birds don't fly this high. Airplanes don't go this fast. The Statue of Liberty weighs less.

Astronomical markers of the seasons, solstice and equinox dates are based on the Sun's place in its annual journey along the ecliptic, through planet Earth's sky. At this solstice, the Sun reaches its maximum southe..

2021년 12월 20일자 도착할 우주여행 장소는 사진에 나온 장소입니다. 여기는 The Comet and the Fireball 입니다. This picture was supposed to feature a comet. Specifically, a series of images of the brightest comet of 2021 were being captured: Comet Leonard. But the universe had other plans. Within a fraction of a second, a meteor so bright it could be called a fireball streaked through just below the comet. And the meteor's flas..

2021년 12월 19일자 도착할 우주여행 장소는 사진에 나온 장소입니다. 여기는 Planetary Alignment over Italy 입니다. It is not a coincidence that planets line up. That's because all of the planets orbit the Sun in (nearly) a single sheet called the plane of the ecliptic. When viewed from inside that plane -- as Earth dwellers are likely to do -- the planets all appear confined to a single band. It is a coincidence, though, when t..
