渐盈的新月和渐亏的新月在这张暮光长焦视野的对角处被发现。2月1日，在阿根廷的罗萨里奥，人们捕捉到了地球西部夜空中两个最亮的天体信标的紧密结合。在那一天，细长的新月大约诞生了3天。但在2月12日，月亮可见的阳光下的新月将变成明亮的满月。和月球一样，金星在绕太阳公转时也会经历不同的阶段。虽然它在阳光下的可见月牙变窄，但随着它靠近地球，内行星的表观大小也在增加。在来自太阳系的情人节中，以罗马爱神命名的金星也将在2月14日左右在地球的夜空中达到其亮度的顶峰。

A waxing crescent Moon and a waning crescent Venus are found at opposite corners of this twilight telephoto field of view. The close conjunction of the two brightest celestial beacons in planet Earth's western evening sky was captured on February 1 from Rosario, Argentina. On that date, the slender crescent Moon was about 3 days old. But the Moon's visible sunlit crescent will grow to a bright Full Moon by February 12. Like the Moon, Venus cycles through phases as it orbits the Sun. And while its visible sunlit crescent narrows, the inner planet's apparent size increases as it gets closer to Earth. In a Valentine from the Solar System, Venus, named for the Roman goddess of Love, will also reach its peak brightness in planet Earth's evening skies around February 14.
