Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that repeats every 243 years.

A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun.
The duration of such transits is usually measured in hours (the transit of 2004 lasted six hours). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is almost four times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth.
Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 commensurabilities.
The next transit of Venus will occur on 5 and 6 June 2012, and will be the last Venus transit this century; the prior transit took place on 8 June 2004. The previous pair of transits were in December 1874 and December 1882. After 2012, the next transits of Venus will be in December 2117 and December 2125.
Venus transits are historically of great scientific importance as they were used to gain the first realistic estimates of the size of the Solar System. Observations of the 1639 transit, combined with the principle of parallax, provided an estimate of the distance between the Sun and the Earth that was more accurate than any other up to that time. In addition, the June 2012 transit will provide scientists with a number of other research opportunities, particularly the refinement of techniques to be used in the search for exoplanets.
A transit of Venus can be safely observed by taking the same precautions used to observe the partial phases of a solar eclipse. Staring at the Sun without appropriate eye protection can quickly cause serious and often permanent eye damage.

The transit of Venus is amazing. We had a great view of it in Australia. Nice video and explanation! Thanks.
you're right, its the waiting that makes it more exciting. ill save a seat for ya.
On the sixth in the morning, starting at 5:30 on sunrise until around 6:30 when the transit ends.
thanks for uploading.
Very nice video!
it is cloudy I ll wait for a next one :)
OH GOSH, Thank you so much for telling me to never look directly into the sun, I totally would have looked at it if you hadn't.
Thank you!
Let's make it BIGGER !
This will start on June 5th Tuesday at 3:07PM pst / 6:07PM est.
i dont wanna miss it !!
hyh... didn't know this channel is still alive...
I would assume no because the heat gets distributed to a larger area when it's projected to a screen or a paper. So the heat energy of a lit match concentrated in a point straight into your eye through the eyepiece isn't the same as the same amount of energy spread out on a large piece of paper. If you've ever tried to light anything on fire with a magnifying glass, the distinction should be clear.
YAY two special things happens on tuesday for me. my birthday and this YAY!
Can't wait! :D
:D I CAN SEE THE TRANSIT! THANK YOU FOR THIS INFO! NOW, I HAVE A GOOD PICTURE OF TRANSIT VENUS! THANK YOU! ;D
I was meaning that if you take a conservative estimate of life expectancy and say that the average person born within 70 years of the second transit in each pair will be able to see both, then the probability of a randomly selected person being able to see both is greater than .5
It did occur in 2004 and will again in 2012. There is no possible way anyone born between 2004 and a2010 will see it more than once unless they live well over 100 years. Realistically it's no more twice in a lifetime than once and a lifetime.
You can prbably find a video of it on youtube afterwards
Watch it online guys!
I'm using 3 layers of shade film on front of my binoculars, I see Venus at the upper right. :]
I'm using a small refractor to do solar projection. :D
i think im going to miss this transit but ill mark my calender so i dont miss the next one.
How could I have been made aware of this BEFORE it happened.
Is there a site or society that posts regular updates such as meteor showers and events like this?
Damn, that's completely disappointing.
Man, bummer.
Gawd damnit its stormy D:
In Europe (I'm in Germany), will it be visible at the morning of the 6th, or when? I'm a bit confused by the diagrams.
:) nice!
Will los angeles see it?
Darn the gawds. I live in Ireland where the transit will not be visible. *sob*
is it possilbe to film it as i live in a village no fields no mountains or even a telescope
Huh? Surely this is more often a twice in a lifetime occurrence if it happened in 2004 as well?
It usually happens in pairs twice a century.
The transit will be on Tuesday, not Monday.
If its as hot as a lit match, wouldn't it catch the paper on fire?
~Safe viewing tips~
Do Not Use:
Sunglasses,
Multiple Sunglasses,
Mylar Balloons,
Mylar Food Wrappers (Pop Tart Bags, etc.)
Smoked Glass
X-Ray Film
Film Negatives
CD's or CD-ROM's
Stacked Welder's Glass
Liquid Filters (coffee, tea)
Can use:
Proper glasses specifically made for eclipse viewing,
Number 14 welder's glass,
Use ONLY solar filters SPECIFICALLY DESIGNED for viewing the Sun!
Also Do Not put on the eclipse glasses and then look through binoculars or a telescope.
Happy viewing =)
Where could i watch Venus transit online? Does anyone know that? :)
RUclips, meet the shorthand police chief of the internet...
The dislike bar is like the shadow of Venus on the Sun :)
02:15 So, I could light a cigarette in the projection?
A shadow on the sun??
...but mama that's were the fun is..
A shadow on the sun?
It was very cloudy, I couldn't watch anythings...))
Venus is a disk!
come on man we're not so stupid as to stare at the sun directly.
"Do so online" But that's not as fun!
or pop popcorn
Goto Nasa.gov to see it live
oh no! ill be working tomorrow! Why!!!???
I'd just like to remind everyone: DO NOT TO COMBINE THE GLASSES WITH OPTICAL MAGNIFIERS SUCH AS BINOCULARS. THIS IS UNSAFE AND CAN PERMANENTLY DAMAGE YOUR EYES.
oh...ill be working tuesday too T_T so it does not matter anyway
It will damage your eye. Severely...
YAAFA, NPOAD. You're welcome.
Loool XD
Will it damage my telescope? It's a cheaper one.
Sun? In England? Don't make me laugh.
you're being sarcastic right?
I enjoyed this video. Here is a mystery: Jesus Christ claimed to be the morning star. And I would like to know how Venus could be related to himself. He is one with the Creator of these heavenly objects, so he would know, being one with our heavenly Father.
I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star. [ Revelation 22 : 16 ]
