2004 Venus Transit In Pictures
oneiros27 writes "For those astronomy fans out there -- pictures are starting to come in from the 2004 Venus Transit (where Venus passes in front of the sun). Times of the transit will vary by city, but make sure you use safe techniques for viewing the sun if you want to look for yourself."

I'M BLIND!!!!
I tried to look at Venus, and I burned out my eyes! Damn you Slashdot, damn you Sun! (The Sun, not Sun the Java people!)
It would be interesting if someday human could live in Venus (w/ the little help from terraforming), and experience the transit directly from there.
NASA.gov is in for the Slashdotting of its life!
When an event such at this occurs once in a lifetime, for the scientific enthusiasts or hobbyist, this is more than just a round disc blocking another shiny round disc.
We will learn more about this planet and how the corona varies compared to an eclipse.
If you look at the NASA website, it's just entered the sun's corona (from Earth's perspective). It hasn't actually gone past the disc yet, but it's still visible to the SOHO telescope.
Karma: Segmentation fault (tried to dereference a null post)
This is a big desert, you could really get hurt out here. Now go away.... remember that you saw nothing.
I suggest you read Slashdot
The Australians will only be able to view a partial transit. According to my New Scientist, Eurasia and Africa will be able to view the entire transit, Eastern North America, South America and Western Africa will find that Venus will already be in transit at Sunrise, and Australia, Japan, Alaska and Indonesia will find the transit interrupted by sunset. New Zealand, the Western US and southern Chile will be unable to view the transit.
It says that you can project an image of the sun with binoculars, Im hoping that a telescope will work as well, if not, watch the news for "Wild fire obliterates southern ontario, /.er in questioning"
Dear aunt, let's set so double the killer delete select all
At least we'd all get an article on Slashdot....
actually dear poster its a twice in a lifetime experience..
the next transit is due in 2012
(+1 wiseass..)
transists come in pairs with venus, there shoud be another one in a few years then it will be a long time till the next pair.
Dear aunt, let's set so double the killer delete select all
From the article on safe viewing:
"More recently, solar observers have used floppy disks and compact disks (both CDs and CD-ROMs) as protective filters by covering the central openings and looking through the disk media."
My Dear Watson, I have discovered another use for AOL CDs! Grab the one from under that cup over there; we're going to watch Venus!
It seems there is a Canadian atmospheric research satellite that will also be making measurements of Venus. They are using a infrared Fourier transform spectrometer and cameras with the hope of improving models for extra-solar transits (think finding ET).
I'M BLIND!!!!
For one thing, it doesn't start for another day and an hour or so.
(I'll admit that I panicked and rushed outside and took quick looks at the sun, before I came back and read the article and realized we still have about 25 hours until it even starts.
For another thing, slashdot was kind enough to post a link to safety instructions in the headline.
So, what are solar filters? How much do they cost and where can I get one if I want to drive across the country in a mad dash to catch it at sunrise in South Dakota or whatever?
I've been wanting to check out that Wall Drugs that so many people have bumper stickers for for awhile anyway. Maybe they sell solar filters? But if I'm going to drive halfway across the country I want more then just a pinhole thingy.
Who's up for a road trip?
But if you forgot safety and go temporarily blind, at least you can turn your Chinatown apartment into one big computer and discover a way to predict the stock market.
Howdy Doodly Doo!

Back when the Magellan mission was mapping the surface of Venus, I had a planetary geology friend who was involved in assigning names to features. I managed to persuade him to name a crater after my girlfriend Marianne, as a birthday present to her. At the time I thought this gift was pretty cool; unlike star names, which are meaningless, this was an official designation, and furthermore Venus was the Planet O' Love.
My mistake, however, was to forgetting that Venus is eternal, but love isn't. Every time I see Venus hanging in the evening sky, I realize I named that damn crater after the wrong woman. LOL!
Tubal-Cain smokes the white owl.
Ok, let's get a list of public viewings together.
Here's a list of web casts.
Anyone else have information on live viewings?
Thanks.
Opinions on the Twiddler2 hand-held keyboard?
Yes, it is safe, if you're using #14 or darker glass.
A band called Bananarama did a cover of a song called "Venus" in the eighties (1986). It was originally done by Shocking Blue* in 1970.
Lyrics here.
It is a bit of a stretch to go from from a story on a planetary event to a forgettable eighties band, but this is /.
* That site also tells us that "Venus is the only song in the history of the Billboard charts to hit number one three times (first time on February 7, 1970, second time on June 20, 1981 by "Stars On 45"; third time on September 6, 1986 by Bananarama)." So there. Wow. And now I can't get the damn song out of my head... she's got it, yeah baby she's got itWhen they came for the communists, I said "He's next door. Take him away. Goddam commies."
The BBC and Open University have a nice section on this. Its worth looking at.
You can calculate the distance of the earth from the sun.
If you're in the UK, the BBC have some programs covering this on Tuesday. There's live coverage at 9.50AM on BBC1 and another program on at 12PM on BBC1. Theres a full hour program on BBC2 at 11.20PM. All presented by Adam Hart-Davis.
Here is the map of the transit for 2004.
And here is the map of the transit for 2012.
So while I won't get to see it this year unless I hop in my car and drive east for about 20 hours without rest, I will get to see it in 2012, unless I'm in Chille or Argentina, or something.
The further north you are, the better your chances of seeing it.
If you're in Antarctica you won't see it at all.

The term eclipse is reserved for those events where the front object is large enough to significantly cover the back one.
During the transit Venus will only cover about 1/900th of the solar disk and as such this is not usually referred to as an eclipse.
What matters are the apparent sizes of the two bodies not their actual sizes, for example, the Moon is nowhere near half a million miles in diameter but when it transits the face of the Sun the event is called an eclipse. This is because, from the surface of the Earth, the apparent sizes of the Moon and the Sun are very similar and the moon is capable of blocking out a large fraction of the solar disk, sometimes even cover it completely.
Imagine you travelled to Venus during the transit - the disk of the planet would get larger and larger until around 1 million kms (630 thousand miles) from the planet it would be large enough to totally eclipse the Sun.
...I'm tempted to make a Soviet Russia joke about them Slashdotting us...
What, like how in Soviet Russia, Nasa slashdots you?
Hope be with ye,

Just thought this might be an interesting thing to share with you:
"There will be no other [transit of Venus] till the twenty-first century of our era has dawned upon the earth, and the June flowers are blooming in 2004. What will be the state of science when the next transit season arrives God only knows." - William Harkness, USNO, 1882
