12,667. What was observed by us in the third place is the nature or matter of the Milky Way itself, which, with the aid of the spyglass, may be observed so well that all the disputes that for so many generations have vexed philosophers are destroyed by visible certainty, and we are liberated from wordy arguments. (Milky Way & Galileo) Galileo Galilei
3,355. Quasars blast away huge quantities of gas from the surrounding galaxy. The equivalent of ten Earths every minute. Black holes suck gas in; quasars blow it out. But eventually there’s no gas left to make stars. And the galaxy stops growing. With no gas left to feed on, the quasar jets shrink and die. What’s left is a super-massive black hole at the centre of the galaxy with a lot of infant stars. Just like our Milky Way when it was young. (Black Hole & Quasar & Galaxy & Milky Way & Universe) How the Universe Works s1e2: Black Holes
3,395. We live in a galaxy called the Milky Way. An empire with hundreds of billions of stars. There are two hundred billion galaxies in the known universe. Each one unique, enormous and dynamic. (Galaxy & Milk Way & Star & Universe) How the Universe Works s1e3: Galaxies

3,397. Our galaxy contains many billions of stars. And around many of them are systems of planets and moons. But for a long time we didn’t know much about galaxies. Just a century ago we thought the Milky Way was all there was. Scientists called it our island universe. For them no other galaxies existed. Then in 1924 astronomer Edwin Hubble changed that thinking. (Galaxy & Milky Way & Star & Universe) ibid.
3,399. Andromeda our nearest galactic neighbour is over two hundred thousand light years across. Twice the size of our galaxy. (Galaxy & Milky Way & Universe) ibid.
3,400. They all seem to orbit something at their centre ... A black hole. And not just any sort of black hole: but a super-massive black hole. The meal is gas and stars. And it’s being consumed by the super-massive black hole. But sometimes black holes devour too quickly. And what they’re consuming is discharged back into space as beams of pure energy. It’s called a Quasar. (Galaxy & Milky Way & Black Hole & Energy & Quasar & Universe) ibid.
3,401. The black hole at the centre of the Milky Way is gigantic. Twenty-four million kilometres across. (Galaxy & Milky Way & Black Hole & Universe) ibid.
115,723. The Milky Way: a galaxy of over 200 billion stars. But where did it all come from? So what was it? What sparked our galaxy into life? New research has suggested a source: is the great destroyer of the universe actually a creator? Did a black hole build our galaxy? (Universe & Black Hole & Milky Way) How the Universe Works s3e7: Did a Black Hole Build the Milky Way?

116,760. The fate of our galaxy hangs in the balance. The Milky Way is dying. And we don’t know why. The hunt is on to find the cause. It’s a cosmic Why investigation. And every possible reason is under suspicion and will be scrutinised. What is killing the Milky Way? (Universe & Milky Way) How the Universe Works s6e6: Death of the Milky Way
116,761. Repeated dwarf-galaxy collisions could have radically altered the shape of the Milky Way itself … Are dwarf galaxies killing the Milky Way? (Universe & Milky Way) ibid.
116,762. The Milky Way is eating itself to death. (Universe & Milky Way) ibid.
3,371. If you want to see a black hole tonight, tonight just look in the direction of Sagittarius, the constellation. That’s the center of the Milky Way Galaxy and there’s a raging black hole at the very center of that constellation that holds the galaxy together. (Black Hole & Milky Way) Michio Kaku
3,381. Astronomers had an existential shock! In one year we went from the universe being the Milky Way galaxy to the universe of billions of galaxies. (Galaxy & Milky Way) Professor Michio Kaku
3,391. The new hybrid galaxy, half Andromeda, half Milky Way, will be more of a ball than a disc. In its core two super-massive black holes will orbit each other in a tightening spiral until they finally merge. As our new galaxy falls towards the Virgo super-cluster more titanic collisions are in store. (Galaxy & Milky Way & Black Hole) Unfolding Universe
3,393. Throughout the universe galaxies crash into each other at phenomenal speed. This may be the fate of the Milky Way. The most violent impacts in the universe occur when galaxies collide ... Our own galaxy is at risk of crashing with its closest neighbour Andromeda. (Galaxy & Milk Way) Cosmic Collisions: Galaxies
3,394. It’s a collection of gas, dust, planets and millions and millions of stars. (Galaxy & Milk Way) ibid.
3,518. A broad and ample road, whose dust is gold,
And pavement stars – as starts to thee appear
Soon in the galaxy, that milky way
Which mightly as a circling zone thou seest
Powder’d with stars. (Star & Milky Way) John Milton, Paradise Lost
104,317. There is a region at the core of our galaxy the Milky Way where nothing escapes … a super-massive black hole. (Universe & Galaxy & Milky Way & Black Hole) The Universe s1e9: Alien Galaxies, 2007
3,361. It’s a crucible of creation. And destruction ... Now astronomers have pierced the galaxy’s heart of darkness to find out a way through the Milky Way. (Milky Way & Universe) The Universe s2e4: The Milky Way
81,102. It’s one hundred thousand light years in diameter. Has a trillion times more mass than our sun. It began about thirteen billion years ago. And is still under construction. This is our galaxy. The Milky Way. (Milky Way & Universe) ibid.
81,103. This is where we live. Our solar system is among the Milky Way’s spiral arms twenty six thousand light years from the bustling centre. The galaxy is so large that it takes the Earth two hundred million years to complete one lap. (Milky Way & Solar System & Universe) ibid.
81,104. A community of two to four hundred billion. (Milky Way & Universe) ibid.

81,106. The Milky Way sounds like something kind of comforting. Sweet. But the Milky Way is a monster. Professor Michelle Thaller, NASA & Caltech
81,107. Just recently we’ve discovered that there are two small galaxies colliding with the Milky Way right now. And the only reason we didn’t know there were there is because there is were so much dust at the disk of our galaxy ... With infra-red you can cut through that dust ... So saw these little galaxies up there coming right at us. Professor Michelle Thaller
81,110. Our galaxy, the Milky Way, is one of 50 or 100 billion other galaxies in the universe. And with every step, every window that modern astrophysics has opened to our mind, the person who wants to feel like they’re the center of everything ends up shrinking. Neil deGrasse Tyson
