How am i supposed to ever go to sleep when you tube is so darn interesting

I always love how so many of these sounds of space, sound like something from a 1950/60s science fiction film.

Man, even comets sing better than I do.

My sleeping cat sat straight up and listened to the 3rd recording!

Sound cannot travel in space, so how can you record a comet? This is a very common question in the comment section of this video, perhaps I should have gone into more detail (hindsight is a beautiful thing). So to help answer this question, here is more information on sound recording number three, the singing comet audio. In the vacuum of space, there is no sound, acoustic waves require a medium, such as a gas, liquid or a solid to propagate through, the atmosphere of a planet, for example. The coma that surrounds a comet, although sometimes referred to as an atmosphere, would not allow for traditional acoustic waves to travel, it is too tenuous. But there is another type of wave that can propagate in the mixture of charged particles and ions, or plasma, present in the comet’s environment. These magneto-acoustic waves are caused by the interaction of the local plasma around the comet with the magnetic field carried by the solar wind, a stream of electrically charged particles blown by the Sun. While probing the magnetic environment of the comet, the Rosetta spacecraft detected these waves as very regular oscillations in the comet's magnetic field. We cannot see magnetic fields, but we can transform their oscillations and make them audible, allowing us to hear the bizarre sounds of a comet. I hope this helps answer this question. Space is full of incredible sounds, we just have to find different ways to listen to them! Thanks, Rob

The first sound just sounds like a typical winter day driving in Michigan. Ice pelting off the windshield…

That 3rd one I’m gonna use for my alarm.

At 5:20, it sounds like what I would think a giant praying mantis would sound like. Kinda creepy but interesting! New subscriber, thanks for the vid.

The third audio sounds like the Predator creature.

The video from the surface of the comet is absolutely awe inspiring!

These findings are bizarre and amazing all at once

Don't you need AIR to hear sound? Explain that one please.

Isn't it amazing that we can not only see these magnificent frozen objects but also hear them as well? Let me know which one is your favourite. It's got to be recording number 3 right?

Thanks for the audio.

Always excited when you post a video! Thank you!

That was so eerie! I honestly didn't realise that sound can exist in the vacuum of space. I thought that sound waves had to have an atmosphere to happen. Obviously, I didn't learn about this in physics at school. I also thought that the surface of comets would be smooth, what with them travelling at incredible speeds. I thought that it would wear at least the leading surface smooth, even though I can't imagine that there'd be much friction, but considering how long these bodies have been travelling for, I thought that the eons of time would have allowed for this. Not only that, but I didn't think that there'd be what really looks like loose particles on the surface, from large rocks to lots of dust. How do they remain on the comet? I'm not stupid, but I find it hard to comprehend how this happens. Please, will someone enlighten me? Don't be mean, though! I'm always willing to learn! Thanks.

I was around in 86 when Haley's comet made it's last pass around the sun. As of last Dec. 23 it has just begun it journey back inwards toward the sun. With a good measure of luck I might live long enough to be around in 38 years when it swings around the sun again. 🤞 Thanks Rob. Hope you and Rolo have a great weekend. 🇺🇸❤🇬🇧

Thanks Rob, fascinating as always and brilliant pictures and video.

Yes! Great video indeed. Keep 'em coming.
