About Venus

Venus' celebrity is far from a recent phenomenon. Throughout history, numerous (at least 30) cultures have observed, been enthralled by and found their own name for Earth's sister planet. Often depicted as a female (although in some Native American stories, it is a male character), Venus the planet and its atmosphere present an extremely hot and hostile environment. The planet's sheer radiance may be a key to its sway on the imagination - Venus surface is completely shrouded in highly reflective clouds, making it the most brilliant object in the night sky other than the moon. Additionally, because its orbit is inside the Earth's, Venus can be seen shortly after sunset and before sunrise at different times of the year. These appearances occur in an eight-year cycle, an observation the ancient Mayans of Central American used to construct a highly accurate Maya Calendar.

Venus' brightness and periodic proximity to the Earth have also made it useful in some of history's most significant astronomical advances. Venus has been in the sights of telescopes since the beginning, when Galileo discovered the planet's moon-like phases. Galileo's discovery was a milestone in the modern understanding of the Sun-centered (heliocentric) solar system. In addition, Venus has played a very crucial role in many modern advances in science. Early measurements of the speed of light were derived from observations of the transit of Venus across the solar disk. In the late 1960s, Venus was hit by the first radar signals to bounce off a solar system object. And in 1983 the former Soviet Union's Venus orbiter, Venera 15 made the first radar observations of another planet from an orbiting platform.
