The transit was a very rare astronomical event that would not be
seen again for another 105 years.
Observers in north and central
America, and the northern-most parts of South America saw the transit begin
just before local sunset.
The far northwest of America, the
Arctic, the western Pacific, and east Asia witnessed the entire passage.
The UK and Europe, the Middle East,
and eastern African waited for local sunrise to see the closing stages of the
transit.
Venus appeared as a small black dot
moving slowly but surely across the solar disc.
Special events provided safe ways
for the public to see the transit
Some of the best pictures of the
event have been provided by the US space agency's (Nasa) Solar Dynamics
Observatory, which studies the Sun from a position 36,000km above the Earth.
"We get to see Venus in
exquisite detail because of SDO's spatial resolution," said astrophysicist
Dr Lika Guhathakurta.
"SDO is a very special
observatory. It takes images that are about 10 times better than a
high-definition TV and those images are acquired at a temporal cadence of every
10 seconds. This is something we've never had before."
Many citizens keen to get a view of
the transit themselves have been attending special events at universities and
observatories where equipment for safe viewing has been set up. For others, internet streams have provided an easy way to
follow Venus's slow trek.
Scientists
have been observing the transit to test ideas that will help them
probe Earth-like planets elsewhere in the galaxy, and to learn more about Venus
itself and its complex atmosphere.
