HONOLULU (AP) - For astronomers, Venus passing in front of the
sun is not just a rare planetary spectacle - it won't be seen for
another 105 years. It's also one of those events they hope will
spark curiosity about the universe.
Sul Ah Chim, a researcher at the Korea Astronomy and Space
Science Institute in the central South Korean city of Daejon, said
he hoped people see life from a larger perspective, and "not get
caught up in their small, everyday problems."
"When you think about it from the context of the universe, 105
years is a very short period of time and the Earth is only a small,
pale blue spot," he said.
As astronomers use the latest technology to document the transit
of Venus, stargazers gathering across the world should only look at
the celestial event with a properly filtered telescope, a strong
welding visor or cardboard eclipse glasses.
If viewed directly, permanent eye damage could result.
Extremely hot Venus is one of Earth's two neighbors and is so
close in size to our planet that scientists at times call them
near-twins. During the transit, it will appear as a beauty mark
moving across the face of the sun.
"In terms of rarity, to be here at a time when it's happening,
you almost have to look at it," said Geoff Chester of the U.S.
Naval Observatory. "It ain't going to happen again in my
lifetime."
The transit is happening during a 6-hour, 40-minute span
starting just after 6 p.m. EDT in the United States. What you can
see and for how long depends on what the sun's doing in your region
during that exact window, and the weather.
Those in most areas of North and Central America will see the
start of the transit until the sun sets, while those in western
Asia, the eastern half of Africa and most of Europe will catch the
transit's end once the sun comes up.
Hawaii, Alaska, eastern Australian and eastern Asia including
Japan, North and South Korea and eastern China will get the whole
show since the entire transit will happen during daylight in those
regions.
In Hawaii, university astronomers planned viewings at Waikiki
Beach, Pearl Harbor and Ko Olina. At Waikiki, officials planned to
show webcasts as seen from telescopes from volcanoes Mauna Kea on
the Big Island and Haleakala on Maui.
NASA planned a watch party at its Goddard Visitor Center in
Maryland with solar telescopes, "Hubble-quality" images from its
Solar Dynamics Observatory Mission and expert commentary and
presentations.
Amateur astronomers from the University of North Texas planned
to watch from points in Alaska and Hawaii to recreate the 1769
expedition of British Capt. James Cook to Tahiti, part of an effort
to use the transit to measure the solar system.
They will use atomic clocks, GPS and high-end telescopes to take
measurements, and will use high-end video gear to capture
time-lapse video.
Experts from Hong Kong's Space Museum and local astronomical
groups were organizing a viewing Wednesday outside the museum's
building on the Kowloon waterfront overlooking the southern Chinese
city's famed Victoria Harbor.
The transit begins there around 6 a.m. local time.
In South Korea, the transit coincides with a national holiday.
Choi Hyungbin, head of the Daejon Observatory, said he was
expecting more visitors than might otherwise come out to watch the
transit. Local media urged residents to visit observatories,
reiterating the danger of looking directly at the sun.
This will be the seventh transit visible since German astronomer
Johannes Kepler first predicted the phenomenon in the 17th century.
Because of the shape and speed of Venus' orbit around the sun and
its relationship to Earth's annual trip, transits occur in pairs
separated by more than a century.
It's nowhere near as dramatic and awe-inspiring as a total solar
eclipse, which sweeps a shadow across the Earth, but there will be
six more of those this decade.
