    Great video. I like that you use actual astro photography an not so much artist impressions

      Thanks. I'm using NASA images, and I want to make sure I give proper credit if needed. That's also why it's ad-free and I'm not monetizing any of these videos.

    I like the way you jump right to the topic and not thank everybody in the phone book and try to sell some crap nobody is interested in.

      This happens because none of my videos are monetized.

      @@JasonKendallAstronomer when you get time please do a video on that tail created by the DART probe. That would be interesting

    as an interested lay-person I was hoping for a clear, schematic presentation of the various flows (plasma, photons, magnetic fieldlines) not only inside the disk but also inside the jets and - most critically - from the disk 'around' the black hole (which is always represented spherically) from the equator to the poles so to speak into the jets! so it remains mysterious, how matter (plasma, photons) flows from the accretion-disk into the jets and in both directions and how precisely the spiral movement of the jets is generated. the illustration you provide of electrons sprialing around magnetic fieldlines seems highly unsatisfactory to me a) because one doesn't understand the cause (geometry of the various charge flows) and the 3d-geometry of the magnetic fieldlines in the whole system (disk, core, jets; interaction of the magnetic fields of the charge flows in the disk and the jets) and b) because fieldlines, I'd say, should not be thought of like sort of seperate strings around which electrons can form distinct spirals... of special interest is the question how the disk, turning just in one direction, and thus producing just one magnetic - toroidal? - field which turns only in one direction can produce jets in two directions...? I'd be grateful for a link to such graphic representations (simplified and schematic or 3D vector fields) of these flows! thank you! mail@culturetripguide.com

    What type of Star it's S0-2 (S2) The only info I found so far is that it's 10-15 solar masses and very luminous, as all the S objects seem to be.
    Also, what do we think the G-clouds are? Proto stars?

    the jets are clearly finite and you mention that they look as if the run into something. what is it that brakes them? and what would happen to two black holes, orientiend axially aligned, whose jets would meet 'head on'? would they drift apart being blown away from each other, so to speak, by gas and radiation pressure?

    2:00 but how big are black holes physically if we can't see them to measure.

      I suggest taking a a stare at my entire series on Black Holes: ruclips.net/video/CGPurPAFVVI/видео.html
      All the best!

    14:42 you mention that jets move at many times the speed of light! How so?

      Good catch! Superluminal motion is an apparent motion across the sky in AGN jets. It's not a "trick" but rather a result of the nature of what exactly is being measured. Take a peek at the oh-so-standard wiki page....
