On September 13, the planet Venus will appear close to the waxing crescent moon in the western sky shortly after sunset. This celestial pairing offers a striking view for skywatchers, with Venus shining brightly as the "Evening Star" just over 5 degrees away from the moon’s slender, 9%-illuminated arc. The event is the first of two close encounters between Venus and the moon this week, setting the stage for an even more dramatic alignment the following day. Venus, often called "Earth's twin" due to its similar size and rocky structure, will be easily visible as a bright point of light in the twilight sky. In contrast, the moon will be more challenging to spot, as its dimly lit face is nearly lost in the bright glow of the setting sun. The pair will appear less than 10 degrees above the horizon at sunset, so observers should find a clear, unobstructed view to the west to catch the spectacle before the sun and its celestial companions dip below the horizon about an hour later. As the moon and Venus rise in the west, look for a subtle glow on the moon’s unlit side, known as earthshine. This occurs when sunlight reflects off Earth and illuminates the moon’s dark portion, creating a faint, ghostly glow. The effect is most visible around the time of the new moon, when Earth’s reflected light is most effective at lighting the lunar surface. On September 14, millions of observers in Europe, North Africa, the Middle East, and southern India will witness a rare celestial event: the moon passing directly in front of Venus in the daytime sky. This phenomenon, called an occultation, will begin at 5:26 a.m. EDT (0926 GMT) and will not be visible from the United States, where the moon and Venus will be below the horizon. Skywatchers should never look directly at the sun through telescopes or binoculars, as this can cause serious eye damage. By September 15, the moon will appear to have moved to the left of Venus, continuing its journey toward its brightest point in the evening sky on September 18.
