Q: It's your last chance to catch one of the rarest cosmic spectacles _ Venus slowly crossing the face of the sun. Weather permitting, the transit of Venus will be visible from much of Earth _ Tuesday from the Western Hemisphere and Wednesday from the Eastern Hemisphere. This sight won't come again until 105 years from now _ in 2117.

 The nearly 7-hour show can be seen in its entirety from the western Pacific, eastern Asia and eastern Australia. Other parts of the globe will catch portions of the transit. 
  
 Here's a sampling of local viewing times: 12:10 p.m. Honolulu, 3:06 p.m. Los Angeles, 5:06 p.m. Mexico City, 6:04 p.m. New York _ all on Tuesday _ and 5:37 a.m. London, 6:10 a.m. Beijing, 6:38 a.m. Cairo, 7:10 a.m. Tokyo, 8:16 a.m. Sydney, 10:15 a.m. Auckland on Wednesday. 
  
 As in a solar eclipse, do not look directly at the sun. There are ways to watch the Venus transit without blinding yourself. 
  
 If you still have your pair of eclipse glasses from the May 20 "ring of fire" solar eclipse, now is a good time to reuse it. You can also find the special viewing glasses at your local museum _ if they're not already sold out. Another option is to buy welder's glasses from a home improvement store, but make sure it's number 14 or darker. 
  
 To celebrate the last transit in a century, museums, observatories and astronomy clubs are setting up telescopes with special filters for the public. Many will also feature special programs including lectures. 
  
 If clouds spoil your view or if you're shut out, there's always the Internet. NASA plans a live webcast from Mauna Kea, Hawaii. Slooh.com and the Exploratorium in San Francisco are among others that will the sky show broadcast online. ||||| Astronomers and stargazers will get a last chance to glimpse a rare astronomical event known as the transit of Venus starting on Tuesday. 
  
 The phenomenon, which occurs when Venus's orbit brings the planet between Earth and the sun, takes place roughly twice a century—the last transit was on June 8, 2004—and won't happen again until 2117.

 Unlike in a solar eclipse, in which the moon temporarily obscures the sun, Venus will appear as a small black dot passing across the sun in the daytime sky. Spectators are advised to wear special solar eyeglasses, or dark, polarized lenses such as welder's glasses, to prevent eye damage.

 Richard Vondrak, deputy director of Solar System Exploration at NASA's Goddard Space Flight Center, said studying the event is "important in understanding our place in space." The transit of Venus was critical to the determination of Earth's distance from the sun, and thus the size of the solar system, Dr. Vondrak said. In the late 19th century, scientists finally ascertained the distance based on data from several transits, after a mathematician first proposed observing the transits back in 1663.

 Jay M. Pasachoff, an astronomy professor at Williams College in Williamstown, Mass., said such events continue to provide scientists with insight into planets in Earth's solar system and beyond. Dr. Pasachoff, who will be in Maui, Hawaii, for the transit, will be studying it for clues to Venus's atmosphere as sunlight passes through the outer rim of the planet. He said scientists hope the same method can be used to study atmospheres on exoplanets, distant planets outside the solar system. 
  
 Viewers on the East Coast of the U.S. can watch the transit of Venus with their protective glasses from 6 p.m. EDT until sunset, Dr. Vondrak said. It can be viewed from most parts of the world, but not from Portugal or from big swaths of Spain, South America and Africa. 
  
 From many parts of Europe, people will be able to view the latter part of the 6½-hour transit after sunrise. Alaska and Hawaii are the only two states from which it will be possible to view the full transit. 
  
 Dr. Vondrak said people can watch the transit without special glasses by tuning in to NASA's live webcast of the event from Mauna Kea, Hawaii, starting at 5:45 p.m. EDT. 
  
 "So many people are missing the fact that it's a 21st-century topic," Dr. Pasachoff said. "It gives us a last chance in over 100 years to test ideas about distant planets." ||||| The rare Transit of Venus is coming Tuesday afternoon in the United States, and it's a once-in-a-lifetime viewing chance for West Coast viewers. The next time this astronomical phenomena will happen is 2117. 
  
 At its heart, the exquisite show in the heavens is simple — Venus will cross paths between the sun and the Earth, and Earthlings will see a tiny dot floating across the surface of the sun over several hours. 
  
 How to view the Transit of Venus? You could buy a pair of solar glasses from a planetarium, like the Griffith Observatory in Los Angeles, which will sell them Tuesday after 12 p.m. for $2.99 a pair. An even better view, also at the Observatory, is seeing the transit magnified by a telescope, equipped with special solar filters.

 You can also try buying No. 14 welder's glass from a welder's shop or home improvement store. Or use a pair of binoculars, preferably with more than seven times magnification, to project the sun's light onto the sidewalk or a piece of paper. If you're able to find an image of the sun, look for a tiny dot showing the image of Venus. 
  
 Don't look at the sun directly. The sun's rays are so bright it will obscure Venus, and you could damage your vision. If all else fails, watch a live NASA webcast from Hawaii. 
  
 This week's viewing will be only the eighth time the Transit of Venus has happened since the telescope was invented, according to NASA's Fred Espenak. It will begin at 3:06 p.m. Pacific Daylight Time, and hit the center of its journey at 6:25 p.m. The sun sets in Los Angeles at 8:02 p.m., but in points west — such as Alaska, Hawaii, Australia, eastern Asia, and most of Europe — the show will go on for two more hours. (The transit will occur on Wednesday for points west of the International Date Line.) 
  
 As long as clouds don't interfere with the view, most of the world will be able to see at least part of the Transit of Venus, except for southeastern South America, western Africa, Portugal and Spain. 
  
 Entire lifetimes can go by with no one being able to see a Transit of Venus, but we're living in a lucky time to see what Espenak calls one of the rarest of planetary alignments. The viewings occur only twice every 120 years. Since the telescope's invention, Espenak says, it was only viewable in 1631, 1639, 1761, 1769, 1874 and 1882; the last viewable transit happened in 2004 but happened before sunrise in the western United States. |||||
A: 
Tuesday night Bingo will have to wait: Barring the discovery of some fountain of youth, today is the last chance you'll get to watch the second planet cross the sun in a simple, twice-a-century phenomenon called the transit of Venus. All the usual rules apply, notes the Wall Street Journal, like don't look right at it. Rather, use solar glasses, No. 14 welding glass, or project it onto the ground with binoculars. Or just watch NASA's live webcast, notes the LA Times. But do check it out, because Venus won't be back this way until 2117. Past transits helped astronomers figure out our distance from the sun, and were vital "in understanding our place in space," one NASA official says. "So many people are missing the fact that it's a 21st-century topic," adds an astronomy professor. "It gives us a last chance in over 100 years to test ideas about distant planets."
