In this segment of our “How far away is it” video book, we cover the structure of the Milky Way galaxy.
We start with a high-level description of the three main components: the galactic center with its black hole, the galactic disk with its spiral arms, and the galactic halo stretching far out in all directions using the European Space Agency spacecraft Gaia’s findings. We also show how full images of the Milky Way can be created from within the galaxy.
Using the full power of the Hubble, Spitzer, and Chandra space telescopes, we take a deep dive into the center of our galaxy with its central bulge. We detail the evidence for the existence of a supermassive black hole, Sagittarius A*, at the very center of the galaxy’s core. We cover and illustrate the work done by the UCLA Galactic Centre Group in conjunction with the new Keck observatory on top of the Mauna Kea volcano in Hawaii, and the Max Plank Institute for Extraterrestrial Physics in Germany and more recently and the European Southern Observatory with its array of Very Large Telescopes in Chile. This includes a look at how close the star S2 approached Sgr A* and what that black hole might look like. In addition, we cover stellar interferometry with ducks on a pond to see how these measurements were done.
Next, we go a level deeper into the nature of a Black Hole singularity. We cover the Schwarzschild radius, event horizon, accretion disk, gravitational lensing, and gamma-ray jets. We then actually build Sgr A*. In addition to the supermassive black hole, we take a look at a solar mass black hole.
We then cover the structure of the galactic disk including: the bar core, the two 3 Parsec arms, Scutum-Centaurus, Perseus, Sagittarius with its Orion Spur, Norma and the Outer Arm. We review the locations of various celestial objects we’ve seen in previous Milky Way segments, to show how close to us they are. We also cover the disk’s rotation and the Sun’s orbit. We look at our solar system’s Ecliptic Plane with respect to the galactic plane. And we cover the galaxy’s dust clouds and how we see them with radio astronomy. We also cover the galaxy’s rotation curve and its connection with dark matter.
Next, we cover the galactic halo. We start with Shapley’s globular cluster map that first showed that we were not at the center of the galaxy. We cover the size of the halo, the inner and outer halos orbital motion, and the newly discovered galaxy within our galaxy called Gaia-Enceladus. We end with recent discoveries of massive amounts of Hydrogen in the halo and this findings impact on the Dark Matter debate. And we end with a calculation of the entire Milky Way’s mass.
We end our galaxy coverage by illustrating how far one would have to go to take a picture that would include what we see in our illustrations. We conclude the chapter with another look at the distance ladder that took us across the galaxy.

Thank you for your work, this is so fascinating... I got back into Astronomy following forced retirement due to back injuries. I don't sleep well so instead of watching tv from the couch when I wake up in pain, I go outside and observe with my 10 and 12 inch Dobsonian telescopes... I have learned ALL of the sky from my latitude in Victoria British Columbia Canada. Thanks again!!!

David Butler can put you to sleep. In a good way. I was watching something about ants where David Atenburough (jees, spelling? ) last night and my wife was trying to put blankets on me and I kept yelling about ants all over me for some reason. Don't remember a thing. I just fell asleep to an ant documentary. Ok. goodnight hopefully.

So we feel so alone... where are all the aliens? Is there a great Fermi filter etc etc... but now I know the answer.. I believe there are millions of alien civilizations but THEY ARE REALLY REALLY REALLY FAR AWAY!!! If its gonna take voyager 562 MILLION years to reach that photo point, and us humans have only been watching space for what... 200 years? Even a close alien civilization would be VERY hard to communicate with. Talk about waiting hundreds or thousands of years for an answer to a signal.

The Black Holes.. no matter how many times I have heard about them it still blows my mind, 17:11 "In this region, space itself is dragged around by the black hole's spin" its impossible to imagine something having that much power. - Also wouldnt it be wild if humans and life on earth is not of the Milky Way but of Gaia Enceladus?

There is just one problem with your measurements of light speed: it is valid at one point time with one point position in the Universe. It does not take inflation in account.
Chris Schaiberger
Chris Schaiberger Maand geleden
Agreed...but recognize that in virtually every possible realm of measuring anything the assignment of a value is valid only from 'your' unique perspective. The designation of a fixed value, much less a maximum, to the speed of light has forever been an obscene claim. Our delving into the essence of the realities of 'physics' is nothing but infantile at best. The future will be bemused by our having claimed the certainties now promulgated.

Ok people, enough with the incorrect paradigm.. black holes do no exist and have been scientifically debunked by Pierre-Marie Robitaille , PhD and S.J. Cothers. Many of you are so engrossed in the teachings of old, which by the way, had the science incorrect on many very important topics. Don't believe me, as of course you will not, but seriously.. do your own research with an open mind and lets get this back on track. Yeah it may seem hopeless, why would over a century of what has been taught, be revisited to ensure the accuracy of theories etc... academia has nothing to gain... and why would any professor, especially those who are being funded on their work, change that in which they have revolved their entire life on.. ( albeit, and sadly on bad science) but I still have faith. Why am I even spending my time and energy on this... BIG SIGH!!

Very Ver Very good information. What people cant understand is they are looking at controlled Creation. Everything you see in our Milky Way is involved in the creation of our Milky Way. Creation might go on for millions of years but i promise you it will be controlled by a Mighty force that is in charge of every thing in the Milky Way. We are very privileged to have scientist that dont lie.

Hear you now the mystery of mysteries: learn of the circle beginningless and endless, the form of He who is One and in All. Listen and hear it, go forth and apply it, thus will you travel the way that I go. Mystery in Mystery, yet clear to the Light-born, the Secret of All I now will reveal. I will declare a secret to the initiated, but let the door be wholly shut against the profane. Three is the mystery, come from the great one. Hear, and Light on you will dawn. In the primeval, dwell three unities. Other than these, none can exist. These are the equilibrium, source of creation: one God, one Truth, one point of freedom. Three come forth from the three of the balance: all life, all good, all power. Three are the qualities of God in his Light-home: Infinite power, Infinite Wisdom, Infinite Love.

Good afternoon, hope you are well and continue to keep on teaching thicko's like me...quicky question, you said that the newest Milkyway mass estimate is 1.5 trillion solar masses, I think I remember seeing somewhere that Andromeda mass estimate was 500 billion to 1 trillion solar masses and its usually described as larger than the Milkyway, sometimes said to be far larger. So is Andromeda now smaller than the Milkyway or am I comparing apples to oranges and have got the wrong end of the stick? Edit, Just occured to me to ask something else if this does get your attention, Concerning fusion in stars...Why is the next step up from Helium Carbon via triple process, why dont 2 Heliums fuse to form Berylium? or Helium and Hydrogen fusing to form Lithium or some combination of the two fusing to get Boron? Why does it go from element 2 to Carbon at 6, why is there never a Boron or Lithium or Berylium shell in the cores of stars?.....I did warn you im a thicko if this question is really stupid. Ive one more question...but lets leave it at just 2 today....Have a nice day!

Let me ask you one thing that is we,our planet is just beside of big big milky way galaxy.And it is so much huge...big more than billion lightyrs of our solar system. The questiin is how do you see the over view or the top view of milky way galaxy...as we can see today.I think it is so much big and so far away,watching from the ground or by satallite.... My questions is may be childish or.... cause i want curious!....Pls reply Best regards...
