This is a photograph of Venus at dawn. All the stars have disappeared and in the sky there is only the bright spot of Venus and the crescent moon.
Venus is the easiest planet to distinguish with the naked eye. After the sun and the moon, it is the brightest object in the sky. Its dense atmosphere of carbon dioxide and sulfuric acid reflects sunlight and makes it look very bright white.
Venus is closer to the Sun than Earth. Therefore, it can only be seen at certain times and always in the same direction as the Sun. To the east in the hours near dawn and up to a couple of hours later. Or to the west when it is visible at sunset. The months in which it is visible in the morning, is the last bright spot to disappear, hence its name "the morning star". We can never see it during closed night hours, because at that time the Earth is oriented towards outer space and the planets farthest from the Solar System.
Although it cannot be seen with the naked eye, from the Earth Venus presents phases. With a telescope it is seen without difficulty in its increasing or waning phases.
