You know exactly what he meant! if he said "Venus is larger than the moon but appears smaller on the sky", etc, EVERY single time, these videos would all be about two hours long! :)
Don't miss our new astronomy channel DeepSkyVideos
"Venus is much much smaller [than the moon]"
Are you allowed to say something like that if you're a physics professor?
Saw the transit from the top of the cable car in Tromso. My first Midnight Sun. Perfect weather! Best seat in Europe! I am ecstatic!
im flattered you took the time to visit good sir
Love how he spends time explaining it's significance and building it up, but then he sums up nicely with "it's just a little black dot travelling across the face of the sun".
I'm so blessed! I live in the part of the world where I can see the whole transit, and Brady made this video upon my request!!!(probably much more than mine since I believe most of the viewers knew this in advance). Thank you so much, Brady!! I really love the video! Would the transit be a little late for you?
I got to see the 2012 transit of Venus from my back yard. I didn't have a sun filter, but instead used a small telescope to project an image of the sun onto a card.
I could listen to this guy talk all day...one of my favorites!
Waiting eight years for the chance of observing? That's dedication.
i love how you guys get this every video
I did, thank you! A huge blanket of clouds rolled in like literally 10 minutes before the transit started, we still stuck through with our plans, and the clouds cleared for a few minutes. Some nice folks from a local astronomy club let us watch it through their equipment, which was modest but let's face it, still far better than my welder glasses! I swear I could hallucinate the transit just fine watching the sun through my welder glass though! :P it was still nice to actually see it for real..
Thanks again Brady. You give us for free, an education many shell out multiple-thousands for. I really do appreciate your hard work and also the willingness of your stable of brilliant Professors to willingly impart upon us the knowledge they have worked so hard to obtain over the years. The Professors in your arsenal truly are wonderful people. I was not able to finish my degree, and to continue learning like this means very much to me. Thank You.
WOOOO!!!! new sixtysymbols vid!
Mike will be pleased you thought so (if I can get him to read the comments!)
fanatastic, talking quite passionete for a good 7 minutes about this event and in the end it is just "a black dot passing in front of the sun"
love this video again Brady, as I do all of your videos on all of your channels!!
greetings from the Netherlands
Oh that's awesome thanks for the tips!
thank you for bringing us this video i found it very infomational and i enjoyed it thank you
enjoy!
I love how there is this big discussion about how amazing and rare this even is, then in the last 10 seconds he basically says fuck that I'm not getting out of bed to see a little black dot move across the sun. Awesome...
All that great info, but not cool enough to wake up early for!
I could listen to this guy all day long...
nice video!
Yeah, and you may like to consider visiting the location with a compass beforehand, and try not to pick peaks or ridges. I know it sounds counter-intuitive, but in summer, morning mists may be quite regular around mountains and affect the observation. At least it is true in the part of the world I live in. I picked a reservoir for the annular solar eclipse last month, also progressing in sunrise, so you can also consider this option.
great videos! makes me proud to live in Nottingham :D
I know perfectly well that this will not be a spectacular event in terms of eye candy, but being able to see it with your own eyes is something special I think. Gives me a sense of where I am in the solar system. I'm in the UK now, but hopefully I'll be at 24E longitude in time for the transit - less chance of horizon obstruction.
Hi Brady! just to let everybody know welding glasses or face shields are very good for looking at the sun safely, it was not mentioned and they would be much easier for the average person to acquire
wooot, getting excited for this, since it'll be late afternoon to sunset here! I'm going to test out my solar projecting rig this weekend (hopefully it works!) and get ready to spend an evening on the roof! I know it's not the most spectacular thing to see, but to be able to say I've seen it will be worth the effort. Not to mention that it gives my neighbors something else to wonder about...
I am PA aswell and will also be trying to observe this through my telescope! Its my first year with a telescope and I'm really hoping to get pictures of this.
very interesting. thanks
My dad did that for the solar eclipse a few weeks ago. It was pretty interesting.
"It's a little black dot traveling across in front of the Sun!" LOL
any pics?
I'm here in Pennsylvania, I have a nice Mac-Cas hobby telescope and a solar filter I bought a few years back. Hoping I can catch it when it happens :)
smoked glass possibly using the soot off a candle flame.
Alternatively, you could use a pinhole camera type of thing.
I've had this discussion a few times already... I am not trying to write Sixty Symbols in Greek.
I have chosen symbols that resemble the shape of the letters... Like when someone writes football and replaces the Os with balls, etc.
But is it makes it easier, you can think of the project as sixtps sgmbfls!
Yea, I caught that too. Obviously he meant that from where we are on earth, Venus "looks" smaller than our moon.
What Will We Miss? - Vsauce
Miller welding helmet set to 12. I just used it to watch the awesome ring eclipse.
"It's a little black dot going across the surface of the sun"
Yeah i meant to add an addendum that even with a 12 it should only be for very very brief moments. Unfortunately It was too cloudy in Seattle at the time of the transit but i had my little solar telescope ready just in case.
Question: is a welders mask adequate for viewing the transit? I know it blocks out enough visible light, but want to make sure it blocks out other wavelengths (read: UV etc) so I can show my young neice and nephew this historic event.
It would be defintly bigger :) as for transpacency thats interesting quastion, most likely it would be translucent on part of the clouds that lights go thru.
His stance on getting up to watch the transit makes me feel much better about missing it.
Atlas of Creation on the shelf? Is it the one by Harun Yahya? Is that a leisure time read or a part of an astronomer's research literature?
Sorry, I meant outside Earth's orbit. That why retrograde motion is observed in all of them (Mars and beyond)
That goes for telescopes with reflecting mirrors. Refractors don't succumb to these scenarios, so they're used for projecting the image.
6:30 Nice shot!
thank you
Just to be sure, smoked glass is NOT SAFE. The only safe filter, including specialized solar filters, are #13 and #14 (better) welder's glasses. They're quite cheap and absorb enough UV/IR and visible light.
Love how passionate people were in the past in terms of discovery! Imagine, spending 8 years alone just waiting for another chance to witness what you spent who knows how long getting into position with a boat, by no means a financially small task.
brady, thank you for making this stuff. and thanks to these scientists brilliantly excited about what they do. even though my mom says she was interested in this sort of things when she was like 15, after which she went on to become a professor in chemistry (her interests becoming more particular), and i'm a 23 year old dickhead, i still find these videos excellent. there is no bad knowledge after all)
Did you get to see the Venus transit?
It's best if it's rated at a 6 or above, but yes. I used one for the eclipse and I don't think it damaged my eyes at all.
Yes, but you should use #14, that's the darkest glass available. You can use #13, too, but #14 is the best.
It blocks UV and IR, as those rays emanate from electric arcs welders work with.
that'd be cool
I like how he summed the video up for laymen at the end. "It's a little black dot travelling in front of the Sun!" - glad that line wasn't the whole video ;)
By the way, is that Harun Yahya's Atlas of Creation on the back shelf there?
What time would it be visible in North America on the east coast? Would the pinhole method for viewing solar eclipses work for viewing this?
Hah, I love how he speaks the entire video about how amazing this is, then at the end he's like "It's just a little dot traveling across the sun! No big deal" :P
where would i buy those kind of glasses
Some people seem to think that because it's a rare event, it makes it worth watching.
I saw it like that in 2004, It worked perfectly!
I have a question.
Where does charge come from?
Yea about the same, around sunset, I'll be out watching at about 5pm so i don't miss it, though the forecast isnt looking good.
Do you know what times to be watching? After a quick online search it appears it'll begin transit around 6pm for me, then end around 1am :/
CD's work pretty well too, but be careful of the hole in the middle ...
Go to places with flat terrain north-east, like seaside, if u live around there
My dad loves genealogy, and he found out that my direct ancestor--William Crabtree--was one of two to see the first recorded Venus transit and predict the next one. :D
Where can I get those glasses?
I projected the image of the Sun using my Odyssey 8 dobsonian, through an eyepiece that I felt comfortable melting. I stopped the aperture way down too, of course.
And don't forget to let it cool down sometime, especially if you're using one of your favorite eyepiece!
You're right, and I should have known my source on that was unreliable. I guess I'm just lucky that I didn't look for too long and severely damage my eyes during the eclipse.
where can i seee it live?
Is there any way I could improvise those eclipse glasses, because there's no way for me to get a real pair.
Yes, but that is very rare. Wikipedia entry on Venus transits also mentions double Mercury and Venus transits at the same time, also very rare.
Yeah, northern Norway was maybe the best place to watch it:)
I hope i can use my 400mm lens without an ND filter, so long the sun is still low on the horizon. Would love to record this.
I live in the UK but me and my mum will be getting up at the crack of dawn to see it.
As I write this, if I look down, I'm actually observing the transit of Earth in front of the sun. Turns out it covers the Sun entirely! By using trigonometric calculation methods on the difference in Earth position while I move my head, I figured out the distance to the Earth is 1.86 cm. Gotta love this stuff...
While I decrease the distance to Earth, as my head falls to the pillow, I wish you all a good Earth transit :)
i've done it before, put 3 on at the same time and its pretty well blocked. One was a good pair of ray bans though.. wither that made a difference I couldn't say.
I, personally, will look at it with binoculars. All you have to do is take a piece of paper point the binoculars at the sun, and focus the sun on the piece of paper. In theory, I should be able to see the event! :)
In relation to how far away it is and the size it appears, yes it is...
Around what time does this supposed to happen today.?
not what I was talking about, but thanks for sharing. lol.
I will look directly to the sun through my telescope. THIS GOING TO BE AWESOME
Why do these transits occur in (relative) pairs?
When will the transit be?
Haha, I love how Prof. Merrifield just can't be bother, like meh, it's only a dot going across the sun... :P I personally can't wait, I've been categorizing light curves, looking for exoplanet transit signatures pretty much everyday with Zooniverse, so maybe I'm biased, but my dad's welder glass hat is gonna get some love next tuesday! ;)
Is Mercury too small and too close to create such a visible event?
I'm in the UK, how's the best way for me to go about seeing this?
As long as they're shade 14 or above, I think.
I think that was the point ;)
I live right next to the North West coast so maybe that's a good sign
how much damage does looking at the sun actually do?
Me too, but we play with the cards we're dealt.
The transit reminds me of buses, you wait a lifetime and two come at once...
Varies, how long you look at it, and how sensitive to light your eyes are. Such as a blind person, non really. You won't go blind from looking at the sun on the first go, unless you have a pre-exisiting condition. But your eyes expanding to absorb that much light will do damage.
Yeah i saw it with my naked eye, with 2 pairs of sunnies, and the 3D glasses from the movies :D
There was only 'ecliptic' and 'transit path' on the picture at 2:00, so if ecliptic wasn't what you were talking about, then transit path? If you are instead referring to the E/W being on opposite sides, its because that is the east side of the sun when looking at the sun from earth, as it relates to the earth from space. If you were standing on the sun, then it would be the other way around.
ahahaha "it's a bit early in the morning for me"
Venus will cross the sun here during sundown. Would it be alright to view it without glasses even when it is close to the horizon?
