Moving around the Sun on an orbit inside that of the Earth, Venus displays phases like the Moon, cf. VT-2004 InfoSheet D3. The famous Italian scientist Galileo Galilei (1564 - 1642) first observed Venus's phases in 1610 with the recently invented telescope. This contributed to convince him that Venus moves around the Sun and is illuminated by this body and that the Sun, not the Earth, is at the centre of the world.
On this page, photos of Venus's phases are displayed in chronological order, as they were photographed before and after the Venus transit on June 8, 2004 and are now shown at the VT-2004 website. Please note that the orientations of these photos depend on the equipment used and are therefore not uniform.
Early in 2004, Venus was about "half", but as it moved along its orbit between the Sun and the Earth, we began to see it more and more "from behind". Consequently, the illuminated part of the disc steadily diminished and right before the transit on June 8, Venus' crescent had become extremely thin. At the same time, some of the sunlight was refracted through the Venusian atmosphere, creating the effect of an illuminated, partial "ring". The same phenomenon was observed on some photos taken when Venus "entered" and "exited" the solar disc at the time of the transit.
All photos on this page may be downloaded and used, provided the photographers (authors) and the VT-2004 programme are indicated as source.
