Artificial laser star over Yunnan Astronomical Observatory, Yunnan, China. By focusing on the artificial guide stars in the form of the laser beams, telescopes are calibrated to remove the effects of the atmosphere on observations, a process known as adaptive optics. The Milky Way is visible in the night sky at right, with zodiacal light also seen. The Milky Way is our galaxy seen from the inside, forming a band of stars and nebulae stretching across the sky. Zodiacal light is sunlight reflected from dust particles orbiting in the plane of the solar system. From Earth it is seen as a cone of light along the ecliptic, the orbital path of the Sun, Moon and planets in the sky. Photographed on 26 December 2013. | |
