thank you so much for posting this...no one will see one of these again for a long long time...hugs to all sky lovers out there...may you never get enough of what you love.
That scene is from ESA Proba-2 which is in sun-synchronous orbit. This means it's constantly in line with the sun while passing the equator multiple times per day. This means the viewing angle depends on its relative latitude and results in the oscillation you describe. All the other scenes in this video are shot from NASA's SDO which is in geosynchronous orbit and thus has a constant viewing angle.
According to ESA . "Venus appears to wobble thanks to the slight up-down motion of Proba-2 and the large distance between the satellite and the Sun" It's a bit vague what they mean by up and down, but it's probably its orbit which lies on a latitude, and therefore moves up and down relative to the sun.
Fantastic bunch of footage. I especially like the images where you can see the sun's magnetic flux lines, like a huge goddam bar magnet on the surface.
It shows you just how much beauty we have in the world, how much true, and utter beauty that this universe contains. Why clog it up with other thoughts when you see how little, and insignificant we are in comparison
Very nice video. Went up at 5 AM to get a view myself, only able to see a projection from a telescope onto a sheet of paper though. We'll see if the weather is OK year 2117 as well. Already subscribed so I'm waiting for the superduperultra-high-def video in the subscription feed in 105 years...
The event itself is pretty unspectacular, but its significance is important. It proves that our theories about how the planets move are at least partly accurate.
The cause of the oscillation in the first sequence is due to the parallax effect, as the satellite Proba2 moves along a Low Earth Orbit, with 100-minutes of orbital period (roughly). If you watch carefully you can count between 3 and 4 bounces (periods) of Venus, up and down, while it is over the sun. Infact: dividing the Venus Transit time (5h 52min) by the orbital period of the satellite (100min) you get approx 3.6 periods :) which is a good result
The one view where it seemed to be bouncing was because that was from a earth (ground) based telescope. The rotation of earth caused it to look jittery; whereas you notice the other views through the video shot it in a straight line because they are orbital telescopes.
Your comment gives me some hope for the human species, as do all of the "likes" your comment got. Learning can really be great. Let's respect those with knowledge, and those who really want it.
I said the exact same thing. It's either a flaw in the video introduced in post-production, or it's the way cooler idea that the image was taken at a specific wavelength and at that wavelength Venus is not opaque.
Theres a big difference between remarkable and impressive. You'll also be how pressed to impress anyone subscribed to a channel called "best of science" with such trivial stats.
The camera sensor is operating at a very high cadence and the rapid succession of images doesn't give it time to reset between each. That makes the image of the bright sun linger like a ghost in all frames.
Venus had two small moons, Ignolus and Laro. Ignolus is made mostly of metals and is very dense. So dense, although you cant see it, it causes the planet to wobble. Much like how planets are sometimes found around stars.
The camera sensor didn't have time to go back to it's initial state so the image of the bright sin remained as a ghost in the frames. Normally this camera takes one image of the sun every 10 minutes so it has time to reset in between (and from what I've heard they also take shots "in the dark", with the hatch closed, to further reset it) but at this event it took an image every few seconds.
I am completely in awe of those images of our own sun, to be able to see inside our closest star is a complete mind-fuck. Don't get me wrong the transit was amazing, but its the images of our sun that has blown me away. Go N.A.S.A you rock
The shots are likely taken from different spots across the planet, giving a slight angle to Venus against the backdrop of the sun. As I recall, Venus transited the sun for several hours, and was visible across Earth. However, local weather conditions may not have created favorable conditions for picture taking in any one area for the entire transit- even if it were possible to take the entire transit in in one area- and so it would have been stitched together from a number of areas.
I thought so too at first, however, if you look at the pics really close, like at 1:06, you will see that it is actually the light that bends around the planet. The "contour" which makes it look somewhat transparent changes angle as the planet moves, to bend along the planet. But I might be wrong, I'm an engineer, not an astrophysicist. :)
ESA's probe orbits Earth, the transit took seven hours, so it did several orbits during it, causing the up and down motion. NASA's SDO is located between Sun and Earth, that is why same doesn't happen here.
The close-up entry's from 0:50 onwards seem to make Venus appear translucent. As it passes the curvature of the Sun you can see the Sun through it. Its like an X-ray of the planet Venus.
Those shots are taken from spacecraft on earths orbit. Since it orbit from top to down (so it can always see sun) and there its great distance between sun and venus we have this effect. The same effect you can see when you stand up and your monitor will be lower but background don't be effected so much.. Sorry my English isn't best. Cheers
its being filmed from a sattelite that orbits earth in less than one hour. Thats what the wobbling motion in the first clip tells you, nothing more nothing less. Actually the wobbling motion could be used to derive the orbital characteristics of the sattelite.
Glad to see you figured it out. I do have to agree with you about maybe a little more info for the not as informed might be a good idea. It is especially hard for someone who hasn't ever looked through a telescope before, ie the moon is upside-down as well as it's a mirror image. Flipping this image right side up causes it to be on the wrong side of the telescope because its still a mirror image. Hope that helped, cheers
thank u so much for sharing this wonderful event . here in ontario canada it was raining cats & dogs yesterday which made impossible to see it in real life .
Seen it with my own eyes through one of the telescopes in school. I took several photos rather similar scene at 1:24 using my iPhone 4S looking into the telescope. It was about to exit.
More than likely it is an artifact created by CCD that captured the video. Kind of like when you stare at the sun and then see spots in your vision when you look away.
Well, I'm sure we don't know everything there is to know. There's most likely things we can't observe (yet), or things that have only happened once, or things that happen so rarely we have never had the opportunity to observe them. Since we have observed this, we know at least this is true. In science/knowledge, there's always more to learn.
I TOOK THE BIGGEST BONG RIP RIGHT B4 I WATCHED THIS AND THAT WAS SOOOOO COOL. I LOVE OUR UNIVERSE AND THE MULTI-VERSE AS WELL.. I SURE HOPE WE ALL GO LIVE AMONGST THE STARS AFTER WE DIE. AWESOME SHOTS!!!!
@walkabout16 G'day... Thanks for sending this ! Them there genuine Rocket Scientists got some lovely shots, indeed. Remarkably, the most Expensively-Obtained view (from Orbit) was the wobbliest... I still reckon the Hillbilly Method of Observing the Transit, which I posted, is the most Cost-Effective way to view the Sun. I had a 60mm Solar Orb, & a 2mm Venus Disc, to look at... Pity it was only 8 Degrees Celsius, & Windy. I kept retreating to the Potbelly. Ciao !
What I mean is that the satellite that filmed this is not leveled like we are standing on the ground so it must be titled hence why it started from left to right instead of top to bottom
Just think, you're using an electrically powered calculating machine, to interface with a worldwide network, bringing magnetically stored information to people through copper and/or glass wires and even through the air itself, to form words on a liquid crystal screen, using nanometer scale circuitry made from sand. All while not dying from malnutrition or disease. All so can reject how awesome science is.
Please please please,why is it ,when venus starts crossing in front of the sun it looks as if the planet is see thru..... optical illusion ??,would like a convincing answer to this question
I meant to watch this live and forgot and was gonna get up early morning for sun rise (i'm in UK) to see the end for myself but forgot that too. I'll wait until the next one (hehe) when i'll be 134 years old ! ! LOL
Am i the only one who thinks it looks likes Venus is wiggling up and down as it goes past the sun for the first 49 seconds? Also i heard from a BBC documentary that they were planning on pointing hubble at the moon(pointing it at the sun would have been bad) to try and pick up the spectrum of Venus. If their analysis comes off with the atmosphere of Venus as they know it to be then that means theyre correct in their analysis of exoplanets :)
A poorly educated guess: The FIRST image/video was complied from multiple angles. Earth's rotation during those shots likely caused the illusion of Venus moving in the wave pattern.
+stephenexmachina Retrograde motion refers to the change of direction of the planets as they wander through the fixed background of the stars. Most of the time the nightly course is east to west in fairly predictable paths near the ecliptic. Occasionally each planet turns around and moves to the east ('backwards') for awhile, then turns around to head westward again, making a loop or zig-zag against the star background. There are two good explanations or models to explain retrograde motion. One involves a geocentric view, where the sun and planets go around the Earth which is stationary. The other is a heliocentric view, where the earth and planets go around a stationary sun.
after Venus has passed the right edge of the Sun, can we see it going farther into space in its orbit? that would be super-awesome....although very difficult, I imagine, to capture!!!

This was a "one time" life event. VIDEO IS MARVELOUS. Thanks NASA & Others.
Wow! You read my mind and answered my question 2 hours before I thought it! Thanks
it is so aw inspiring to see an actual planet pass by and at the same time reallize how big the sun is compared to it
I really hadn't thought of the transit from your perspective. I totally agree. Thanks for the insight.
Schöne Video - Schöne Bilder :)
Danke :))

I'm so happy I was alive to see this happen last year.

Awesome! Watching the little black dot from the little blue dot.

Venus had two small moons, Ignolus and Laro. Ignolus is made mostly of metals and is very dense. So dense, although you cant see it, it causes the planet to wobble. Much like how planets are sometimes found around stars.
It's definitely a lot clearer than the photos I took on my camera phone pointing through a telescope.
The camera sensor didn't have time to go back to it's initial state so the image of the bright sin remained as a ghost in the frames.
Normally this camera takes one image of the sun every 10 minutes so it has time to reset in between (and from what I've heard they also take shots "in the dark", with the hatch closed, to further reset it) but at this event it took an image every few seconds.
Is it just me or does the soundtrack make this extremely epic?

SO BEAUTIFUL AND INSPIRING, I CANT WAIT TILL WE CAN TRAVEL FREELY THROUGH SPACE.
ESA's probe orbits Earth, the transit took seven hours, so it did several orbits during it, causing the up and down motion.
NASA's SDO is located between Sun and Earth, that is why same doesn't happen here.
Next transit of Mercury: 9 May 2016
stunning,
Simply stunning.
The close-up entry's from 0:50 onwards seem to make Venus appear translucent.
As it passes the curvature of the Sun you can see the Sun through it.
Its like an X-ray of the planet Venus.
Stunning videography, fantastically edited!

Spectacular.!
It's like when you hold a torch up to your thumb, you can kind of see through your thumb. Given enough back light even planets are see-through.
Congratulations, you've just reached level 2 meta.
i am sad i couldn't see it in miami, it was so cloudy, but this video made me fell better
Solar wind, reflection and your own imperfect visual perception certainly make it look like you are seeing through Venus, doesn't it.
I wish I had a HD laptop to see it even more beautiful.....
Why does it look like it's moving up and down?
its being filmed from a sattelite that orbits earth in less than one hour.

What I really found cool was the sun, I've never seen so much detail about it :D
Absolutely magnificent.
Marvellous.
man, seen like that the sun is truly a fiery ball of scare
Wow, I've never heard the sun being described like that before. :p
thank u so much for sharing this wonderful event . here in ontario canada it was raining cats & dogs yesterday which made impossible to see it in real life .
How beautiful!
Thank you for the best view in the solar system. No need to wear geeky specs.
idk how but this was so pretty and yet so many trolls in the comments.
Thanks bestofscience

Yes of course the music was produced during the transit. That's why they call it the Music of the Spheres.
Well, I'm sure we don't know everything there is to know.

I love the sun, it is very "small" compared to a lot of other stars in the galaxy. But for us it is everything..
And now Plut's found out about the video too. He's jealous he's not in the star system anymore :3
I TOOK THE BIGGEST BONG RIP RIGHT B4 I WATCHED THIS AND THAT WAS SOOOOO COOL. I LOVE OUR UNIVERSE AND THE MULTI-VERSE AS WELL.. I SURE HOPE WE ALL GO LIVE AMONGST THE STARS AFTER WE DIE. AWESOME SHOTS!!!!
Excellent! Awesome! Different views of the sun, on so many spectrums
Great NASA entertainment production! Today: Venus in the role of a sunwalking tumbleweed.
How beutiful the universe is !!! Amazing
i got chills

because the viewpoint changes a bit during the transit as the SDO orbits around the Earth
Mesmerizing!
Universe, I love you so much
Great film. It's only a pity that there is no explanation about how each of the different views have been filmed. (filters, type of light...)

Please please please,why is it ,when venus starts crossing in front of the sun it looks as if the planet is see thru..... optical illusion ??,would like a convincing answer to this question
Its has to do with the light and the camera. Post it on yahoo answers in astronomy or in photography both will give you detailed answers
Very cool BestOfScience.
Very beautiful!
Just so others know, the different wavelengths of light are in the description in the last paragraph. I was about to ask for annotations. :D
thanks for the explanation I wonder why the others didn't have the same effect
DAS ist wirklich BestOf .... WOW!!!
I meant to watch this live and forgot and was gonna get up early morning for sun rise (i'm in UK) to see the end for myself but forgot that too. I'll wait until the next one (hehe) when i'll be 134 years old ! ! LOL
Depends on the distance to the sun or other bodies (earth/moon) And yeah, i think there all filmed by satelites.
amazing. thanks for upload!

uall give this guy thumbs up
Singapore. Nearly 12pm on 6 June 2012
"There's a little black dot on the sun today..."
Should have used The Police's song, KING OF PAIN.
I love you! That was driving me crazy :)
esa/rob interesting bounce !!! possibly calibration illusion from craft
back in the ancient times this event was celebrated almost worldwide. nowadays it's just a minor event that most dont even know or care about....
I would expect it to be due to the camera taking the pictures were in orbit around earth, and this is in fact a parallax effect. But I don't know...
What's the music played at 2:00? It sounds like the requiem for a tower piece.
oh and in case i forgot mispellings aren't incidental when they change the meaning of a word.
BEAUTIFUL! :)
oh my god is perfect!!!
Much better than flying to Tahiti to see it, huh? Ya I thought so.
A poorly educated guess: The FIRST image/video was complied from multiple angles. Earth's rotation during those shots likely caused the illusion of Venus moving in the wave pattern.
I'm no genius...but the zig zag probably is caused by camera movement and has been corrected digitally so that the sun's position doesn't jump.

FUNNY HOW ITS WOBBLE GETS ALSO MAGNIFIED AND YOU SEE IT LIKE DANCING AND PRANCING ON THE SUN...LOLL
wow good shit man. thanks a lot!
