목성과 토성 800년만에 초근접<br />Tonight is a once-in-a-lifetime treat for stargazers as Jupiter and Saturn will form the closest visible alignment in 800 years.<br />The two planets align every twenty years in what's known as the "great conjunction". But on December 21st, they will appear just one degree apart, the closest alignment since 12-26. <br />Astronomers say that this rare event is best observed with a telescope,... but it can also be seen with the naked eye.<br />We'll have a live update during our main evening newscast. <br />
