Weekend Pick: Why Winter Is the Best Time for Stargazing

Winter offers some of the clearest night skies in Korea because cold, dry air reduces water vapor and dust—NASA says atmospheric transparency can be ~20% higher than in summer—making stars appear up to 1.5 times sharper. Of the 21 first-magnitude stars visible from Earth, seven can be seen in Korea during winter, including Sirius (in Canis Major), Betelgeuse (in Orion), and Procyon (in Canis Minor). These three form the “Winter Triangle” (겨울철 대삼각형), a useful guide to nearby constellations. Under good conditions you can also spot nebulae and star clusters with the naked eye, such as the Orion Nebula (M42) and the Hyades cluster. For best viewing, visit a nearby observatory—many around Seoul and other regions offer weekend programs—or travel to low-light locations like Anbandegi in Gangneung, Unyeo Beach (Anmyeondo) in Taean, Hwangmaesan in Hapcheon, or mid-slopes of Hallasan in Jeju. Note that many dark-sky spots have limited lighting and narrow roads, so take extra care when driving.
