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.
