NASAさんのインスタグラム写真 - (NASAInstagram)「How blue-tiful! 🤩🌌 Near the outskirts of the Small Magellanic Cloud, a satellite galaxy about 200 thousand light-years away, lies this 5 million year young and dazzling star cluster known as NGC 602. Inside the star cluster, bright, blue, newly formed stars are blowing a cavity in this nebula, sculpting the inner edge of its outer portions, slowly eroding it away and eating into the material beyond. Star formation started at the center of the cluster and propagated outward, with the youngest stars still forming today along the dust ridges. Fun fact: Did you know that the color of a star is directly linked to its surface temperature? The hotter the star, the shorter the wavelength of light it will emit. The hottest of stars are blue or blue-white and the cooler ones are red or red-brown. What color star would you be?
