What did ESA's Rosetta-Philae discover at comet 67P/Churyumov-Gerasimenko?

[@astrumspace]

Enjoy the timelapses? After making the first few, I had to keep making more! I found them breathtaking, it feels like you are there when you can appreicate depth and perspective from the movement of the sequence. Also I'm curious to know your thoughts about the CGI sticker in the corner during the CGI sequences? I wanted to create a easy way for the viewer to know if something is CGI or not, if the sticker is not there then you know you are looking at a real images. In the past I have just had a subtle "Illustration" text in the top corner but I guess too many viewers missed that. Thanks for all your support!

[@matthias4]

The ,,CGI" corner is helpful, you might consider another abbreviation for real images (RI for real images, RIT for real image timelapse or something like that) Thank you for all your work, videos, your curiosity and everything else :) I've got the feeling that your narrating voice improves, it sounds more secure/firm

[@Jerbod2]

The CGI headsup is really nice. I like it when I am told something is an artist impression, some people have a hard time distinguishing it.

[@channelantoneon]

I say keep the CGI stickrr, it's convenient to know whether something is CGI or not

[@theColJessep]

I noticed it right away and think it's a very good idea!

[@adventureswithdogs2251]

I agree with your closing statement that "Space exploration is getting exciting!". As a 62 year old, it all began shortly after I was born, so to see how far we've come in those years is especially amazing to me. I've always been an avid reader of science fiction, even as a very young person. It seems that much of that old fiction is becoming science fact!

[@Stigstigster]

This is such a high quality upload. You have put together and narrated some of the most amazing space images I have ever seen. I remember seeing the low resolution images of this comet when the mission was in the news. For you to put together and show the later higher resolution pictures and time lapse is fantastic in conjunction with your commentary. I can tell you put a lot of work into this and I really appreciate it. A gem of a video in a sea of shite that is KZbin. Thank you.

[@Teknishun]

I couldn't say better, obviously a lot of work has been put into this. Highly appreciated content. Great quality, stunning pictures, very captivating narration! Don't stop making these awesome video!

Thanks for covering this, my university was apart of this project and I actually sat on a couple of meetings in a room named after Rosetta. I read about the project and was really fascinated, and it gets even better when you release a video about it.

[@ross-carlson]

Isn't it extremely sad that these kinds of missions aren't front and center with all news outlets around the world? Instead we get to hear from lying politicians, about every horrible crime in our city and the terrible things happening around the world. This nearly brought me to tears in a few places when I'd try to comprehend what I'm actually looking at. HUMANS LANDED A CRAFT ON A FUCKING COMET - that is absolutely amazing and shouldn't be brushed off like it is.

If you are going to love this stuff , it's better to know the truth about 67p. Google the hip bone of a human and come back and look at 67p. All asteroids are the biological identities of gigantic creatures. As told in biblical accounts , there was a huge war in heaven and destroyed many . Allbthe organic compounds mentioned in this video that's ssid to be on the commet are in your body's composition because it was once a living creature thatbwas destroyed by this great war. We are being lied to about the big history of this world and beyond. If a part of these body patrs ever makes it to earth , DNA test will prove it was human mitochondrial DNA in a living stated.

Here’s a fun question for you... both the comet/asteroid missions have found precursors to life. What does that really mean? Is there really life everywhere it can flourish? Were these comets or asteroids from a planet that had life before us in our solar system (that was subsequently destroyed in a cataclysm)?

[@xairak]

Alex, your mention of previously unknown cometary organic compounds evoked a memory of Fred Hoyle’s book The Intelligent Universe, where the author postulates the idea of cosmic panspermia. While I won’t debate any actual of perceived merits or faults of his hypothesis, it is interesting to note that many of his theories are now woven into the discussion of the impact (no pun intended) that comets may have played in the origin of life on Earth, and by inference, anywhere. Your presentations are alway “must watch”! Thank you!

[@astrumspace]

Sadly no life detecting equipment on this mission to prove it either way, could have been interesting though!

[@gabrielpena2070]

I always wait every Saturday to watch your amazing videos.

[@RAIDFIX]

Dear Astrum. Thank you for the video. Very nicely presented. From my observation, 67P indicates that the "dirty snowball" hypothesis for comets is not reasonable. The neck of the nucleus appears to have been excavated. But by what? My understanding is that as the comet passes through the electric field of the solar wind, it becomes electrically charged. Sensors have detected this field. As the field varies by distance and location in the heliosphere, there is a change in electrical potential. Electro-cavitation and electro-chemistry would be occurring continuously, explaining the "outgassing". However, it is not reasonable to call the jets and plumes outgassing. The velocity of the particle streams is too slow. Rather, the particle velocity indicates that they are drawn away electrostatically. Also, the behaviour of the jet streams is evidence that the particles are kept in well defined filaments that remain visible for 100s of thousands of kilometers, by electric and magnetic currents in the tail, also measured. The jets too, appear to be derived from spiky outcrops, rather than "nozzles" on the surface, further evidence of electrical cavitation discharges. The intensity of the comet activity is enigmatic for solar heating but perfectly reasonable for electro-effects particularly when it's distance is far from the Sun.

[@bobsmith231]

Wrong. The dirty snowball was given up on long ago. It was a press thing. We have known for some time that the dust:ice ratio is >1. Still plenty of ice though. And there is nothing that could excavate the neck. And please don't say anything about electrical woo!

[@RAIDFIX]

@@bobsmith231 I remember the head of ESA's 67P project espousing the "dirty snowball" idea. It was what ESA expected to find. There is water ice on 67P but the comet is primarily rock. And why should the science community be silenced about "electrical woo"? Isn't science supposed to be open to all ideas and propositions? After all the evidence that the ESA 67P project collected, there is so much that is "unexplained". Perhaps because it doesn't fit the standard model for comets. Maybe time to include consideration of electrical effects in the cosmos?

[@zoompt-lm5xw]

[@sbruce899]

I've watched your channel for several years now, and find it one of the better astronomy channels on KZbin. You touched on a subject that I have asked on another channel but I'm not getting the answers. you spoke of hydrogen and oxygen coming together to form water. I had asked on the other channel how this happens, what is the process?. Is it just that easy, when the two molecules (or three) you get water? I hope some of your Astrum fans can help me with this question, I know Google can't. keep up with the great videos

[@politicallycorrectredskin796]

One of the good things about being old is that I got to see Halley's Comet the last time it came round in 1986. Of course the young might get a chance to see it again in 2061. But I can definitely attest that pictures do not do it justice at all. I went outside the town I live in to see it without any lights disturbing, and it stretched pretty much halfway from horizon to horizon, dominating the night sky. It was clearly visible even during the day.

[@tempname8263]

I'm not a specialist, but I think both gas and dust tails are blown away by the Sun. Dust has much more mass per unit area, so it is not getting kicked out of the comet's orbit as much.

[@astrumspace]

There is definitely some interact between solar wind and the dust tail, but not so much. In fact, a comet can have both tails go in completely different directions! www.universetoday.com/wp-content/uploads/2015/11/Catalina-Nov22-Chris-SchurCROP.jpg

I think it would have been way cool if the Rosetta-Philae probe harpooned 67P and then was flung around while this comet rotated.
